Lockheed Martin Selects Linux for Missile Defense

m3lt writes "Business Wire is reporting that Concurrent announced today that Lockheed Martin Space Systems has selected RedHawk(TM) Linux as the operating system for their United States Army Theater High Altitude Area Defense (THAAD) program." From the article: "Lockheed Martin selected RedHawk for the THAAD program due to the precision and guaranteed response time of Concurrent's RedHawk Linux real-time operating system. Only RedHawk Linux was able to ensure the high frame rates required in their HIL simulation without frame overruns, thereby ensuring the highest quality of system test."

Good point. I don't advocate war either but I do advocate term limits for politicians. What was that saying about old men debating while young boys die??? I don't remember but something to that effect.

Re:Arms

[TheLink]

Old men debating whilst young boys die? Well how about this:

If political leaders wish to send troops to battle for _offensive_ (not defensive[1]) purposes, they have to put their own lives at risk as well.

This could be done in the following manner:
A referendum is held. If there is an insufficient majority, the proposers' lives are forfeit. They are put on deathrow.

If there is actually a majority, there could be a "redemption" referendum, and their lives depend on the results.

A similar referendum is also held if at any time it is found that a politician caused the public to be deceived/misinformed (even unknowingly) and "justify" a war or similar military action.

If a leader's life is not successfully redeemed, but later it is found the war was justified, the leader will get the equivalent of a "purple heart".

The idea is that even leaders who have no qualms about lying about "caring about the lives of soldiers" would then actually think twice about sending soldiers to risk their lives. Even amoral people without a conscience would be inclined to take things a bit more seriously when it's not just a matter of losing the next election, or going to jail for a few years.

After all if a leader thinks it is worth risking the lives of soldiers and civilians, that leader should also be willing to risk his/her life. That's only fair right?

Also, if >= 66% of Nation A thinks it's worth attacking Nation B, then it might be easier for people in Nation B to decide whether to kill people in Nation A or not.

[1] Defensive wars are different of course.

Re:Arms

[demachina]

This is an interesting problem.

Yes it is good to have enough weapons to deter someone bad from attacking, invading or destroying you. There are bad people in the world, and there are people who good or bad don't like what you do or stand for.

A problem today is certain American enemies know full well that they can't go toe to toe with the U.S. in conventional or strategic war. They don't and can't squander $500 billion on weapons, the military and intelligence a year, much of that money borrowed by the way. So they don't even try and don't need to.

What do the do? Well they use hijacked jetliners, suicide bombers, IED's, propaganda and other forms of asymmetric warfare. They have proved in Iraq that they can spend millions of dollars on asymmetric weapons and tie up the U.S. military in knots, which is spending billions a month, and which has hundreds of billions of weapons most of which are useless in urban guerrilla warfare. They can launch attacks that costs millions of dollars, if that, that cause, billions of dollars in economic damage to the U.S.

THAAD is in a lot of ways a good weapon if it works. Its main goal is to keep someone with ballistic missiles from killing people weather they are civilian or military.

There are other classes of weapons which unfortunately are dual use, and can be used both offensively and defensively. There have been times when American's have shunned foreign adventure and aggressive warfare. During those times our defense department was really for defense, to deter attack and counter ruthlessly when attacked.

Sadly political and military elites have at various times forgotten the basic difference between defense and preemptive or aggressive warfare. Preemptive and aggressive warfare is something only bad people, like the Nazi's did. Well not ture, The U.S. for example launched the Spanish American war largely under false pretense and to cover a large colonial expansion in the Carribean and the Phillippines. In the Phillippines there was an entire, lengthy, bloody war in the early 1900's never taught in American history classes where the U.S. ruthlessly killed civilians in a largely vain attempt to suppress an insurgency that didn't appreciate decades of American colonial occupation. It holds a lot of parallels to Iraq today, and probably could teach some lessons if we hadn't pushed it out of our collective conscious because it was so ugly.

I guess what I'm saying is that I'm all for paying for enough weapons to defend the U.S. but the U.S. military is completely beyond that today. Its is a cold war relic turned in to an preemptive, offense tool for dominating the world and that flies in the face of what many people want the U.S. to be. What's worse it isn't even any good to deal with terrorist attacks or insurgencies like the ones in Vietnam and Iraq which are far more likely than a conventional war today.

You also need to look no further than the Duke Cunningham case yesterday to realize the Pentagon is mostly just a vast corrupted mechanism for funneling vast quantities of money from tax payer's pockets in to the pockets of largely corrupt defense contractors.

There is irony that China may well dominate the U.S. militarily and economically in the near future because the U.S. is squandering its wealth on excessive defense spending, and watching its economy wither in the face of globalization, budget and trade deficits. The Chinese might well win World War III without firing a shot. They will win it with a steady stream of containers ships to the U.S. and of U.S. dollars to China. The U.S. spends billions developing new weapons technology and the Chinese spend thousands to steal them. The Chinese will soon have all the manufacturing base to make weapons and the U.S. wont be able to make any without importing them from China.

The Iraq war is different, I think, because it is a war waged for one [set of] reason[s], justified with another, funded with yet another, and finally morphed into something altogether different. It's also irritating how much false information, from all sources, is floating around there, so the citizenry cannot form a coherent picture of what's going. The result: anger and a growing desire to flee, which would be disasterous for all parties involved.

"The Iraq war is different..."

Its not really that different. Its one in a long string of regime changes where the U.S. seeks to take down people it doesn't like, people who don't do what the U.S. says, people that thumb their noses at U.S. corporate interests, who challenge the U.S. on the world stage. The goal is to prop up friendly puppets who defend U.S. business interests and kowtow to U.S. demands.

Its been long established that the surest way for a sovereign leader of any state to be taken down by the U.S. is to have oil reserves and to not sign them over to the control of American/British/Dutch oil companies. The U.S. military and intelligence agencies have spent most of the last century insuring Allied oil companies control of the world's oil fields. The U.S. toppled the government of Iran, and installed a ruthless dictator, the Shah, precisely to put its oil fields in to the hands of American oil companies.

The U.S. has tried unsuccessfully to topple Chavez in Venezuela pricesly for the same reason, to get its oil reserves in to the hands of friendlies.

The only things really different about Iraq is the blatantness of the aggression, the blatantness of the lieing and the fact that it failed badly. Taking down Noriega in Panama was very much the same kind of war, its just it was much better executed and there wasn't the deep ethnic division that there is in Iraq, which is fueling the civil war there. Taking down the Sandinistas in Nicaragua, very similar, its just the war was much more covert and used largely indigenous guerrillas with CIA handlers. American's didn't die much in Nicaragua so American's mostly didn't care, even when the Reagan Administration tore down the Constitution by waging a war Congress forbad. The never ending series of coups in Haiti, pretty much the same thing. The U.S. gets tired of leaders there that don't play by U.S. rules so they arm bands of right wing thugs in the Dominican Republic and their CIA handlers send them to do their bidding.

I wish Iraq really was different but in fact its just how power politics is played. The U.S. and the U.S.S.R did it most of the last century and killed millions of people in assorted third world countries around the globe fighting proxy wars. In the process they created the cauldrons that brew terrorism. Somalia is the hell hole it is thanks to decades of proxy wars to control the horn of Africa. Afghanistan likewise became the base for Al Qaeda thanks to a proxy war between the U.S. and U.S.S.R there. The U.S. is just seeking to shape the world out if its own self interest, and the harvest it is reaping is very, very ugly.

Re:Arms

[AstroDrabb]

As a U.S.M.C I agree with most of what you said. These ultra rich, corrupt politicians have no problem sending me or others off to die while they continue to get the big "phat" pay checks.

However, what I don't totally agree with is this statement:

If political leaders wish to send troops to battle for _offensive_ (not defensive[1]) purposes, they have to put their own lives at risk as well.

Why should it be OK to send people to die for "defensive" purposes? A defensive op could very easily turn to an offensive one where you are fighting for you life.

My position is simple. If you attack the USA, we come and blow the crap out of you. Otherwise we don't fight. By attack I do not mean just some "official" military attack. 9-11 was enough for us to blow the crap out of Afghanistan IMO. However, to just keep going "since we are in the neighborhood" is pretty wrong. We knew Afghanistan had a part in 9-11, not directly, but indirectly. IMO we should have hit them harder. But to continue and go on to Iraq was wrong. Where do we go next? Do we just keep going throughout the Middle East until we wipe it out?

I think a much better approach is to be the "sleeping giant". We should refrain from war as much as we can, we shouldn't just start attacking for any reason. However, if a nation does cross that line, then we go in fast and hard and bring them down. That should send a nice message around the world that A) we don't want to fight. B) if we do have to fight, we are doing it to win.

When I think of how much money has been spent on the "war" on terror, the "war" on drugs, the "war" on $POLITICAL_TERM, it is just sickening.

Re:Arms

[c_woolley]

Not trying to start a fight, but think about this one for a second...

Term limits stop you from being able to vote for a President/Senator that you feel has done a good job, and forces you to have to choose between other people you very well may feel are not qualified. What does a President that is in his second term have to risk when there is a 100% chance he is not getting re-elected? Term limits were created in response to FDR's 4th term in the seat of the President. Since he did die, there wasn't much of a chance to re-elect him anyhow, but for those who did feel the man did an outstanding job, why should someone not have the RIGHT to vote for him again, if he would have been a viable runner? Senators were scared of him being re-elected, because he held so much sway in the public and he was a formidable person to say "No" to when he asked the Senate to complete something.

Like I said, I am not trying to start a fight, and I have heard a few arguements in favor of term limits that do hold water, but this is my honest and open opinion (and not the same as everyone else's, I know). The bottom line for me is that I feel that the people should have the right to vote for who they want, and not be limited in their choices. How can we, as Americans, boast about our freedoms, if we don't have the basic freedom to vote in the candidate whom we feel is most qualified?

Granted, we haven't really had many Presidents like FDR or some of the other greats lately, but if we do manage to find someone that is a good leader, term limits guarantee that he/she will not be in office past two terms, and that we may be voting on the lesser of two idiots again...

WOW, was this ever off-topic! :)

Re:Arms

[theLOUDroom]

Well put.

...nothing else to say really, it's nice to see someone have some perspective about the situation.

Re:Arms

[TheLink]

What I meant by "defensive" is when a nation is directly attacked and under _immediate_ threat, there would be no time to hold referendums and all that.

Shooting planes attempting a 9/11 = defensive. The attack on Afghanistan = offensive.

Shooting nukes that are launched at you while within foreign soil before they reach your country = defensive.

One may wish to come up with a clause dealing with nuking countries that launch nukes at you. It's not very defensive. It's more a "revenge" thing. The threat of revenge is the defense I guess.

However, if a country uses my proposal, I believe far fewer nations would ever view that country as a military threat - what would be the point of nuking that country? You'd destroy most assets you'd want to take.

The "sleeping giant" thing is still compatible with my proposal, in fact it may be complementary.

If there is a war between two such countries, they can proceed to _really_ wipe each other out totally. If you think wiping out the 33% minority who weren't for the war is bad, then go adjust the ratio.

It's still better than many wars where far far more didn't want war but were dragged into it. Most people don't want war. Often politicians/leaders may want a war for their own selfish reasons.

My proposal will help make it clear whether people actually want war or not - after all who pays the most for the war - in blood, money, life?

Typically it's not the leaders. I wish that to change.

Well, I think your proposal is pretty good. As a former U.S.M.C, I agree with you about 97%. I am not a pacifist. So I do not think war is totaly wrong/bad, however I think it is very ugly and should be a last resort. I think what Regan did was the best option. He led the USA to defeat the U.S.S.R without firing a single shot. He beat them politically. Anyway, I agree with you 100% that if our "leaders" want to send _us_ to war, then they _need_ to be responsible for that decision with their lives. If I can die because of their decision, then so should they.

To me, it is really simple. If our "leaders" want a war, then they need to be the first in, and on the front lines. The U.S.M.C. has a motto of "First to go, last to know". Which sadly is all too true. Anytime our military is ordered/voted to take action and a war is not officially declared, those "leaders" should have to put on the flak-jacket and carry their M-16 like the rest of the military is expected to.

Why doesn't Bush send his daughters to the FRONT line? Why shouldn't his to daughters be subject to what we are? Why shouldn't the Bush daughters be subject to having their heads cut off with a dull blade like others in the military?

While I am not the biggest fan of Michael Moore, one of the videos I watched was actually pretty good. He went around DC and was asking all of our "representitives" why their kids were not taking part in the "war effort". Sadly, most just ran away from the camera.

Re:Arms

[daraf]

Perspective indeed.

Yes it is good to have enough weapons to deter someone bad from attacking, invading or destroying you

What do you consider an attack? Does somebody have to directly destroy your troops / invade your land? Weapons are one of the array of tools used to defend the interests of a nation. These interests include, but aren't limited to, integrity of territory, freedom of navigation, strategic interests of allies, and vital economic interests. Aggressors don't always stand up and say, "Hello, I am going to attempt to f*** with you now, I declare war". Sometimes they willingly harbor terrorists, or annex a neighboring state and mobilize the 4th largest army in the world to the Saudi Arabian border, or shoot surface-to-air missiles at your aircraft attempting to enforce a no-fly zone that they agreed to.

A problem today is certain American enemies know full well that they can't go toe to toe with the U.S. in conventional or strategic war ... They have proved in Iraq that they can spend millions of dollars on asymmetric weapons and tie up the U.S. military in knots, which is spending billions a month, and which has hundreds of billions of weapons most of which are useless in urban guerrilla warfare.

The US military is subordinate to and follows the wishes of elected representatives, who ultimately are elected by the people. You want more troops to come home alive? Well, then we can't just overwhelm the enemy with numbers. You'll have to buy better training. You want a fast war, rather than a protracted conflict? Okay ... but fighter aircraft aren't exactly sold below sticker price. Oh, yeah, you'll also need AWACs crews to support the fighters, maintainers to support all the aircraft, and you'll have to build a tent city to house everyone. You want to reduce civilian casualties? Break out that checkbook - those smart bombs cost a premium. Oh, yeah, there will also be an additional charge to deploy and maintain that GPS constellation to guide those bombs.

Asymmetric warfare isn't some mysterious, secret terrorist weapon. It's warfare with blatant disregard for the lives of civilians (or your own soldiers, for that matter), and using information to turn the fickle opinion of an electorate with a culture of free expression, while brainwashing your own people in madrasas.

Used in specific ways, conventional weapons can be an extremely effective counter to guerilla warfare tactics -- reference Linebacker II. For many reasons, we don't always choose to use them in those ways.

I guess what I'm saying is that I'm all for paying for enough weapons to defend the U.S. but the U.S. military is completely beyond that today. Its is a cold war relic turned in to an preemptive, offense tool for dominating the world and that flies in the face of what many people want the U.S. to be.

Many people in the U.S. want their government to protect their interests. An assured energy supply is one of those interests. Did you type your post on a computer? Did you drive today? What about those lights all over your neighborhood, burning away all night -- they make you feel safer, right? Do you get your food from a grocery store (that's all delivered by truck, you know)? Do you want to make sure you can do the same tomorrow? You can spin it however you want, call it "dominating the world" or "nation-building" (though I dare say the current situation in Iraq is more akin to the latter -- promoting stability by building a new democracy in a culture to which the concept is foreign is the essence of doing things the hard way). The fact of the matter is, no matter how much you can get diplomats together to talk and hold hands, there will always be a need to use the military in more than a defensive role to protect our interests. Feel free to move to Europe if you want to send your soldiers out under a NATO flag instead so you can feel better about it.

I think nowadays it's impractical for "kings" to lead their troops into battle, right at the frontline, as in the old days.

I'm no soldier, and never ever want to be one, but I figure most soldiers would be more willing to risk their lives for a particular war if they knew their leaders were willing to risk their lives too (and most of the country were in favour of the war).

You try to make it sound as if we don't have any choice. We HAVE TO attack other countries because we NEED their stuff. But it's not true.

The US has a long history of propping up nasty dictators that later comes back to bite them in the ass.

"Stuff" is a subset of our interests, and in a military context a very small one at that. It's an order of magnitude more expensive to go to war to get "stuff" than it is to simply buy the "stuff".

The U.S. has a long history of propping up governments -- some of which were nasty dictators -- to contain the spread of communism and, by extension, the influence of the U.S.S.R. In hindsight (which is always 20/20), the long-term consequences of such actions makes them seem shortsighted. However, propping up governments seemed to be pretty effective and expedient for most of the ~50 yrs of the Cold War. I'm not trying to be an apologist for past wrongs, just trying to show how those past decisions supported legitimate and important strategic aims.

We should be creating governments that americans would be willing to live under

You, me, and the Secretary of State seem to agree. Condi (from speech in Cairo):

Re:Arms

"most evil or idiotic think that Khomeini, Hussein, and Chavez"

Khomeini came to power THANKS to the U.S. The Mossadegh government the U.S. toppled originally was in fact a pretty progressive government, the only thing they did wrong is they got fed up with the fact British oil companies, who got their foothold in the middle east thanks to colonial expansion from World War I, were taking the lion's share of their countries wealth so they nationalized Iran's own oil fields. The British whined to the U.S. to do something, they did, the CIA overthrew a sovereign government, oh and then they screwed the British too and gave the oil fields to U.S. companies. How did the U.S. put Khomeini in power? They put the Shah in power and he and his secret service were one of the most brutal regimes in the middle east, they were every bit Saddam class, disappearing, torturing and killing their opponents. The Iranian people hated the Shah so much they viewed Khomeini and Islamic fundamentalism as an improvement. Many Iranians hate the U.S. with a passion to this day thanks to the Shah.

As for Chavez he has been demonized by the U.S. as is the U.S. way when they want to topple someone, Kaddafi, Castro, Noriega, Saddam etc. Notice who since Khaddafi started kissing American and British boots, and opening his oil fields to them, they don't demonize him any more? Same guy, trust me. Chavez isn't perfect but the dynamics in Venezuela come down to two groups vying for power which is true of just about every country, especially in the Central and South America. A wealthy plutocracy where a few percent have all the wealth and power, and 90+% who are in grinding poverty and powerless. Chavez is popular with the 90+% who have nothing. He like Castro does some great things the U.S. always forgets to mention:

A. They insure universal access to quality health care for everyone, not just those who can afford it

B. They insure universal access to education, especially university education, again based on need and merit not ability to pay. Cuba turns out huge numbers of doctors for example that provide health care to poor areas around the globe who would have no health care if left to the whims of capitalism

C. They seek to distribute wealth more evenly versus having a few percent who are filthy rich and comfortable while everyone else is starving, illiterate and die young due to absence of basic health care.

Unfortunately Socialism is flawed just like Capitalism. People get drunk on power in both systems and abuse it. Socialism means big government and big government tends to be bad no matter what political philosophy it prescribes to. Socialism tends to trample individual liberties and freedom, but so does Capitalism. Capitalism just uses more carefully crafted and better concealed means to rob you of your freedoms.

Its been long established that the surest way for a sovereign leader of any state to be taken down by the U.S. is to have oil reserves and to not sign them over to the control of American/British/Dutch oil companies. The U.S. military and intelligence agencies have spent most of the last century insuring Allied oil companies control of the world's oil fields.

It's actually a bit broader than just oil, including sugar and fruit. As well as being something which appears to have started with the Spanish American war at the end of the 19th century.

The U.S. toppled the government of Iran, and installed a ruthless dictator, the Shah, precisely to put its oil fields in to the hands of American oil companies.

Wheras Iran's (democratic) government wanted instead to nationalise oil production. Since whilst oil was making foreign companies rich it wasn't doing that much to enrich the Iranian economy.

The U.S. has tried unsuccessfully to topple Chavez in Venezuela pricesly for the same reason, to get its oil reserves in to the hands of friendlies.

The unusual thing about Chavez is that he has managed to remain in power dispite the best attempts of the US to get rid of him. Maybe people in South America are learning some historical lessons. The other thing that must really annoy the US Government is that Venezuela supplies oil to Cuba. Cuba being another country where US "regime change" failed.

"Well, then we can't just overwhelm the enemy with numbers. "

If you are referring to Iraq, for example, sir you have no clue. You can't overwhelm them with numbers unless you are going start indiscriminately massacring innocent civilians, kind of like the U.S. tried in flattening Fallujah. All you do is make the people you have under occupation hate you more, and work harder to kill you. The more troops you put in, the more targets you give them, both in people and supply convoys.

"Did you type your post on a computer? Did you drive today?"

LOL. Most of the power I'm using is unfortunately coming from coal mined right next door to me. There isn't any global power projection necessary for us to have electricity.

As for gasoline yes I do drive, but I telecommute and I drive as little as absolutely possible. You see unfortunately the U.S. has been designed for nearly a hundred years to be completely dependent on gasoline. It was a bad design and a bad idea. Its led to complete dependence on a fuel which is finite, and is now crossing in to short supply, its led to pollution, and people spending 2 hours a day driving to and from work. Some of the worst life style choices imaginable. I have for a number of years lived in a city where I didn't own a car, walked to work and took subways and street cars power by nuclear energy to travel to get about.

So not only have we designed our civilization to be completely dependent on fossil fuels, but big oil and coal have done everything in the power to prevent any attempt to switch to something better. They jack up prices and profiteer like this year, people start switching to alternatives and then they drop prices, through collusion, to kick the legs out from under the alternatives, wash, rinse and repeat. Aren't monopolies wonderful.

STOP LAYING YOUR SORRY ASS LIFE STYLE GUILT TRIP ON ME. The world would for the most part be a better place without gasoline and cars. Save it all for the farm machinery we need to grow food and maybe some trains, ships and planes for transport, not for some dumbass to drive 2 hours a day to get from the suburbs to a job in the city.

I would be overjoyed if all my electricity came from nuclear, hydro, solar and wind.

If "defending my economic interest" means killing people, I'm willing to live with get by with less and live and let live.

Re:Arms

[Anonymous Coward]

How about we only fight when necessary?

e.g. when you are under credible threat of attack.

You make it sound like we didn't have a choice about the Iraq War -- but the choice was made, without a clear and direct threat. Saddam was just another evil pushover 3rd world dictator that didn't really mean much.

Iraq was never any kind of threat to Europe and North America. Even the countries actually bordering Iraq were unconcerned.

except for some oil reserves...

Invading Iraq appears to have cost several times more than simply buying the oil on the open market.
Thus it's hard to see any way in which the governments who decided to invade Iraq acted in their own national interests. Instead a relatively small number of people (who, together with their relatives, have stayed thousands of miles away) have made some money from the suffering of their fellow human beings.

Re:Arms

[Anonymous Coward]

My position is simple. If you attack the USA, we come and blow the crap out of you. Otherwise we don't fight. By attack I do not mean just some "official" military attack. 9-11 was enough for us to blow the crap out of Afghanistan IMO.

The rational for attacking Afghanistan as a response for 9-11 was rather weak. Something along the lines of "The person who we think might have planned the attack might be somewhere in that country."
When you factor in that several of the alleged hijackers turned up alive (or already dead), obviously planted "evidence", etc. The whole "Al Quada did September 11th" simply looks like a very weak conspiracy theory. That's before you get to issues such the primary advocates being people who wouldn't know the truth if they bumped into it in the street.

Re:Arms

[mpe]

What I meant by "defensive" is when a nation is directly attacked and under _immediate_ threat, there would be no time to hold referendums and all that.

Which is a reason for having a standing army. However it's hard to have soldiers protecting your nation when they are elsewhere.

Shooting planes attempting a 9/11 = defensive.

Which is the case of the US and Canada is part of the function of NORAD. Who were utterly useless on the 11th September 2001.

It's still better than many wars where far far more didn't want war but were dragged into it. Most people don't want war. Often politicians/leaders may want a war for their own selfish reasons.

Having some kind of referendum would also help protect against the case where a war is being pushed to further the interests of some third party, be it a nation state, corporation or terrorist gang. Maybe reading (and understanding) "The Art of War" by Sun Tzu should be a requirement before voting too...

I got a *serious* issue with this statement. Were you there? Do you know anything about the fight? Do you know what happened? I have 4 personal friends, Marines, no less that were IN that fight. And you know what, there was NOT ONE civilian killed. Certainly not a massacre as you describe. Our Marines were fighting for their LIVES.

http://www.indcjournal.com/archives/001320.php
http://www.indcjournal.com/archives/001324.php

My close friends were in the line of fire for 16 months, in Fallujah and Tal Afar. There were no civilians, as they were removed from the city PRIOR to military action. In Tal Afar, they were removed by Iraqi Security Forces. The only people left were insurgents, and they were warned - get out of the city or we will take you prisoner. As you all well know by now, they would rather DIE than be taken alive. There were well over 1,000 insurgents left behind during the Fight for Fallujah, but no civilians were harmed. And that's from eyes on the ground, fuck the goddamn liberal media. They get it wrong 90% of the time anyway.

Please, before you go sputing off about things you don't know, do a little research. Most of all, use your reason and logic I know you were blessed with. May I point you in the direction of the BBC produced program on the History Channel - ShootOut! - they have two episodes that deal directly with the Fight for Fallujah, as well as the March for Baghdad (more like sprint, but we won't tell).

*WAH*!!!!!!!! In so many areas of our country, that's the only place for some DUMBASSes to afford a place to live. Who are *you* to judge people for the choices they are forced to make to survive? In order for me to buy a home that I could afford with the job that I have today, I would be forced into a 3 hour commute. That's because all of the homes within a 2 hour commute are over $500,000 USD. Do you really have any idea how much money that is???? No one can afford that on a decent salary, let alone someone who actually WORKS for a living but only makes 10 bucks an hour. Don't they deserve a home too?

And as far as your 'world being a better place'.... PLEASE!!!!!!!!!! Do you *really* think that this country, technology, space, and science would have advanced as far and as fast as they have in the past 100 years since the use of gasoline and cars? How do you think information travelled back in the 40s and 50s? And let me tell you something else - if we had NOT developed all of the technology and engines and transport that is still heavily in use today, you wouldn't even be here. Or your parents would be speaking German or more likely, Japanese. Yeah, the world sure would be a better place without fossil fuels... we'd be just like all the other third world countries! At least *they* only pay 0.16 a gallon for gas. (Sudan, Ethiopia, Nigeria)

If people would stop deriding nuclear energy as filthy and environmentally destructive as they have every day since the 60s, we would HAVE more than a handful of power plants, and we wouldn't have so much of these issues, particularly not with coal and natural gas. We could be like France and Japan where more than 70% of their power is provided by nuclear energy (yes, that's why THEY could sign the Kyoto treaty) - hell, we might have even developed beyond nuclear energy by now if we actually USED it. But NOOOOOOO... all the wonks and the peaceniks are so dumb, they constantly knock it down and spout misinformation.

I'm like you, I would LOVE to see alternative forms of energy. But these things take *time*. They don't happen over 20 years, they happen over generations. Fossil Fuels did. And why the hell do people forget about all the advances we've *made*? And why don't they know that it's not America using up all the damn fossil fuels, it's China and India - as proven in a report released last week. I just hope that SF really does build that tidal power system. I doubt it though, because *waaaaah* it costs too much. STFU! :P

Re:Arms

[demachina]

" And you know what, there was NOT ONE civilian killed."

That is naive to the extreme friend, or maybe military propaganda. You can't engage in a knock down drag out fire fight in an urban area without killing civilians. Sure a lot of civilians left before the assault, so did a lot of insurgents.

The point you are completely missing is when soldiers don't wear uniforms you CAN'T tell the difference between a civilian and a soldier in a war zone. The U.S. military quotes these wonderful numbers of how many insurgents they kill in their various offensives, and never report ANY civilian casualties. Why, because they just declare everyone who is KIA to be a terrorist, with some twisted reasoning that if they weren't a terrorist they shouldn't have been there, glossing over that this war is in the middle of people's homes and businesses. If you just declare all the dead as combatants, wallah, no civilian casualties.

You do also forget there is video tape of U.S. soldiers shooting wounded and incapacitated combatant one at point blank range, both by CNN during the invasion and by NBC in Fallujah. If someone did that to an American you would be screaming bloody murder and war crimes.

I feel for all the American soldiers in Iraq, they are in a difficult situation because they are fighting an enemy that doesn't wear uniforms and play by rules. They can't tell a combatant from a civilians. Soldiers placed in that situation are compelled to shoot first, and they make a lot of mistakes. I'm pretty sure most of them know that they are killing civilians, its is just an inevitable part of an insurgency. A key goal of insurgencies is to get the occupying army to kill civilians because its the easiest way to turn the population against the occupier.

All in all your bullshit is little more than disingenuous propaganda. And don't tell me that since I'm not in the Marine Corp and in Iraq killing people that I can't talk.

Well, it's probably best not to let what you call these things limit your thinking about them. Looked at from the other side of the chessboard, many "defensive" systems clearly have offsensive implications. There may be offensive applications for many components (e.g. shooting down satellites). Even if a system is purely defensive in nature, one of the limiting factors in offensive action is the way it exposes you to harm.

This is why many peaceniks are against defensive systems: because they create the illusion that we can attack others with impunity. As we're finding out in Iraq now, it's not enough just to have the military strength for victory. There are bound to be consequences outside your planning framework.

Re:I was killed by Linux

[mmkkbb]

An effective ballistic missle defense system allows the owner to avoid the threat of nuclear annihilation. It woud probably be most effective against a rogue state with few nuclear weapons, or an accidental launch. This worries countries like China and Russia because it upsets the balance of power between the US and other nuclear powers. The US with a missile defense system could attack another nuclear power without the threat of mutually assured destruction.

I tell you though, what these guys can do does almost seem like magic. What they do is really impressive. Kind of like tracking and shooting a bullet out of the air fired from someone elses rifle. The collision speeds are huge.

What an assinine statement. This was well known, by EVERYONE involved, well before the war started.

Alas, this is 20/20 hindsight. Sure, people paid lip service to this. There was lot of talk of "hard work", but not an inconsiderable amount of verbiage about "low hanging fruit" as well. By in large, most people were deluded as to the extent of our post-war involvement. Present company excepted of course.

If you recall, Mr. Lindsey lost his job a White House economic advisor because he predicted the war would cost in total as much as $200 billion, which we now know to be a gross underestimate. The White House said the war would cost between $50-$60 billion. I think it's fair to say the difference between these estimates is the cost of the aftermath of the initial campaign -- the part that cannot be accomplished with military strength. You can do a 2x2x2 matrix and place yourself in it: for the war then/against the war then. For the war now/against the war now. Underestimated the cost of victory/correctly estimated the cost of victory. I'm against/against/correct. Perhaps you are a for/for/correct, but I think there's quite a few people in the for/against/underestimate box, as well as the for/for/underestimate box.

I don't think we've done a bad job in Iraq, though no doubt things could be better. Remember, it's easy to be a Monday morning quarterback.

Indeed. However since I protested the war before we went in, I believe that I have a bit of a right to say "I told you so" to the people who were for it then and against it now. Those people have no right in my opinion to say they were duped. As you say, you'd have to be pretty stupid to think this was going to be easy, and right now it's going very nearly exactly as I expected it would.

Naturally, if you were for it then and are still for it, you might be able to justifiably claim that you knew this all along, that you were a for/for/correct. However, I believe you wouldn't have much company in that box. But you'd have problems establishing your bona fides. Everybody who is for/for wants to say they they knew all along, just as the for/against want to say they underestimated the costs because they were lied to.

BTW, I hope you realize that much of the criticism of postwar Iraq mirrors criticism of postwar Germany after World War II...and look how that turned out. ;-)

Ah, I see. You're suggesting that Iraq is going to end up carved into two or more states who are mortal enemies. That they'll spend decades facing each other over frozen battle lines. That the fate of the region will remain in balance only through a combination of exhaustive militarization on either side of the line with the added threat of global nuclear conflict? I'd say then that you are most prescient.

Re:I was killed by Linux

[Anonymous Coward]

Haha.. are you for real? A "stable democracy" in five years? You yanks really don't understand what's going in Iraq, do you?

Let me tell you what they won't tell you on Fox News (or CNN, MSNBC, AlHurra or any other US government propaganda outlet, "support the troops" you know). Iraq is in a state of civil war. You get one side of the conflict in the US media (Shias suicide bombing yanks and Sunnis), but outside the "green zone", where US journalists seldom dare venture, there is a full blown civil war being fought.

After the initial phases of the occuptation, even though many Iraqis were extremely displeased with the US, there was a slim hope for reconciliation. It didn't take the US forces long to fuck the situation up beyond all hope though. As an example, take the four "contractors" (a euphemism for hired killers and mercs) who went gung ho cowboy in Falluja. When they started killing civillians, the inhabitants of Falluja responded (rightfully so) by killing these yankee dogs. The US response was to raze Falluja, one of the most modern cities in Iraq with over 300k inhabitants, to the ground, on the pretense that they were combatting insurgents.

Now there is no hope of reconciliation with the people of Falluja and elsewhere in Iraq who have witnessed the true nature of the yankee dogs. There will be no peace with the occupying forces, and there certainly won't be a "stable democracy" (or rather a US puppet government). Instead there will be bloody war and probably a lot of Iranian influence. Way to go yanks. Your lust for blood and riches has once again improved the world. Fuck you, and fuck your family. Greedy yankee dog.

Re:I was killed by Linux

[hey!]

I believe you are missing the point.

1 The USSR fielded and tested satellite killers in the 70s so the ability to take out a satellite is not new.

Relevant to my point, but not a good counter example. It's always been possible. It's never been practical. Making the impractical practical is one definition of technological advancement. Furthermore, you ignore the strategic implications. If the Soviets attacked our satellites, it would be an act of war. They could not engage in an act of war without risking it going nuclear. However, if you had a missile defense systme you believed in that could also destroy satellites, you could believe it possible to deny the other side the ability to counterattack, either by conventional means (by hampering their communications) or by nuclear strike. You'd be foolish to believe so, but it's foolish to predicate your defense on either the competence or incompetence of your enemy.


2 The missile defence system doesn't have to use Linux but wouldn't you prefer it to use an Open Source system to a closes source system?


Irrelevant to my point. I don't think it makes any difference. The system vendor will get source on this kind of contract if it needs it, along with whatever kind of rights it thinks is necessary. Since it only has one customer to worry about, the OS vendor will be happy.


3 I thought GPL was all about freedom? I have heard all sorts of rants on Slashdot when people where trying to stop PGP because terrorists could use it.

4 This is a system that if it works will shoot down missiles not kill people. Most of those missiles will be aimed at civilian population centers since they are currently not accurate enough to hit military targets.


Now we're back on track. This is like saying that having your king well protected or not is irrelevant to your ability to capture your opponent's pieces in chess. Naturally a well defended position is easier to attack from. An apparently well defended position is a good way to lose a game through overconfidence. Furthermore in life, the game never stops, nor is it played on a single board by two sides according to strict rules.

No, I don't think such a system automatically and necessarily limits civilian casualties, even on our side, although it clearly does so in some potential scenarios. Technology is a tool, not a solution.

Yeah, how did that turn out? Oh, right, Germany was split into two countries, both occupied by foreign soldiers for decades. The world lived under the threat of nuclear war during that time because of the (at least perceived) possibility of a Soviet invasion of western Europe. Sure, West Germany did incredibly well economically, with a massive amount of aid from the U.S., plus having an established history of economic strength. And eventually the Wall fell and the reunited country is doing better now. But it's not exactly a great example of how to handle the rebuilding of a country.

Besides which, Iraq is not Germany.

I do understand that a strong defense can be used as an offensive asset. The Grumman F4F of WWII is a prime example. The Japanese Zero could out turn it, out run it, and out climb it. The F4F only strengths where it could out dive it and had better armor. The F4F had a good record against the Zero because the pilots had a much better chance of getting home.

Fortunately THAAD is built by Lockheed, whereas the Patriot is built by Raytheon. Raytheon is the classic example of a large, sloppy, wasteful defense contractor that continues to get defense contracts by purchasing its competitors, leaving it the sole source for many types of systems. My father worked for Hughes Aircraft, a Rytheon competitor, for thirty plus years and he repeatedly had to deal with astounding engineering incompetence in Raytheon-supplied subsystems (the DOD forced Hughes to "second source" many parts from Raytheon; smells like graft to me). Imagine his dismay when Raytheon bought Hughes from GM. He retired a year later after watching idiot managers from Raytheon come in and turn the well-run, competent, efficient Hughes Missile Systems Group into a clown factory. Lay-offs for the old timers making too much money, pay cuts for the mid level guys, and lower hiring salaries for new engineers have essentially turned it into a typical Raytheon division.

I don't disagree at all with this. I think theater missile defense systems are a good idea; to some degree I'm guilty of overgeneralizing to strategic systems.

Personally I think it's irrelevant what they use for software. My point is that division of weapons systems into offensive ones (which therefore are somehow bad) and defensive (and therefore somehow good) is very fuzzy thinking. Offense and defense are inextricably linked so one cannot examine one without the other.

I'm a ultra-liberal, very anti-war kind of person. I'm the kind of person who thinks that weapons systems concepts do sometimes have moral implications. However, it isn't as simple as defensive is good and offensive is bad. Every weapon system that is deployed will, if used, result in some people losing their lives and other people being saved. In Iraq the precision aerial bombardment technology did not protect innocent civilians from "collateral damage" as advertised. However it may have saved many more lives due to the shortening of the campaign. If you fight a war, which eventually one must, then by all means do it with the maximum lethality to enemy combatants.

Re:I was killed by Linux

[gatzke]

It is not perfect, but the fact that it can be done is amazing.

I would take a 50% effective defense over no defense at all.

Don't let them fool you LM is no better. I used to work with the guys they sent to military bases to install security/access control systems. Most of those folks are really nice guys, but when I was helping one of them troubleshoot a problem on the phone I was sorely wishing they would bring in a trained monkey on the other end of the line, at the very least it would follow directions and not argue with me about a system I knew way more about than the installer I was talking to. I'll give them credit, they knew how to get wires run throughout an installation, but putting them in front of anything more complex than a punch-down block was a sure way to get something fucked up, an even the punch-down block was questionable. And talking one of them through SQL commands on a system which was based around an MSSQL database was about as enjoyable as elective dick surgery without anesthetic.

Re:I was killed by Linux

[Chris Burke]

What an assinine statement. This was well known, by EVERYONE involved, well before the war started.

Then why didn't our worthless defense secretary actually have a plan for the post-military-ass-kicking part of the invasion?

If he knew that the post-invasion would be this difficult, but did not develop a serious plan, then he is negligent. If he didn't know, he is incompetent and less qualified than you or I to hold his post.

I don't think we've done a bad job in Iraq, though no doubt things could be better. Remember, it's easy to be a Monday morning quarterback.

Monday morning? What about Saturday Afternoon?! Many of the problems we are having were predicted in advance by established members and ex-members of the military and they were ignored by the administration as being biased and politically motivated. Because of course the admin. isn't...

Saturday
      Asst. Coach: If you don't change your play book, you're going to lose.

Monday:

There is nothing more infuriating than hearing people say that the problems and mistakes in Iraq could not have been known in advance and it's all post-facto criticism, because it means they weren't paying attention in the first place.

BTW, I hope you realize that much of the criticism of postwar Iraq mirrors criticism of postwar Germany after World War II...and look how that turned out. ;-)

If more U.S. soldiers had died "post-war" in Germany than "during-war", this point would be meaningful in the slightest. Clearly, we are not "post-war" in Iraq.

And I hope you realize that much of the criticism of during-war Iraq mirrors criticism of during-war Algiers and Vietnam -- and look how those turned out.

Re:I was killed by Linux

[westyx]

I believe you are missing the point.

1 The USSR fielded and tested satellite killers in the 70s so the ability to take out a satellite is not new. Relevant to my point, but not a good counter example. It's always been possible. It's never been practical. Making the impractical practical is one definition of technological advancement. Furthermore, you ignore the strategic implications. If the Soviets attacked our satellites, it would be an act of war. They could not engage in an act of war without risking it going nuclear. However, if you had a missile defense systme you believed in that could also destroy satellites, you could believe it possible to deny the other side the ability to counterattack, either by conventional means (by hampering their communications) or by nuclear strike. You'd be foolish to believe so, but it's foolish to predicate your defense on either the competence or incompetence of your enemy.

Uhm, the US has had anti-satellite capability for a long long time - IIRC, they were launched from fighters, F-14s I think. Due to various treaties I think they were put in storage.

Re:I was killed by Linux

[sickofthisshit]

"Cut and run" vs. "stay the course" is a false dichotomy.

The question is whether what the U.S. is doing in Iraq is helpful to U.S. security overall compared to *all* the possible variations in policy that could be enacted now.

Like *increasing* troops, or changing their strategy/tactics, or just getting the hell out, or whatever.

Of course, dumbshits who weren't willing to answer tough questions before the war are not the most likely to consider tough questions now, so we get "muddle along, while claiming the *next* political milestone will *really* make the difference, and this is all just *great* for the Iraqi people, and, no of course no general is asking for more troops, and anyone who questions us is a liberal revisionist terrorist-appeasing wimp...."

Re:I was killed by Linux

[hey!]

Your opposition to the war in Iraq is moot.

Alas, too true. However, it is not moot with respect to those who supported the war, continue to support the war, but do so by shifting the goalposts. I think it's important to keep an eye on how the goalposts are moved so we can project our future commitments.

Unless you have a time machine it doesn't matter. The question now, is do we cut and run (which we know will end in disaster) or do we finish what we started (even if you think we shouldn't have started anything).

Well, I think it would be good start to divest ourselves of the kind of baggage that political slogans like "cut and run" have. It leads to emotional decision making where rationality is called for.

Reason says that sometimes you can't finish what you started. Sometimes you do have to surrender, because that's the best thing for your country. But even if you don't have to surrender, even if you fully expect to prevail in most of your objectives, it is sometimes necessary to accept tactical retreat and repositioning, particularly when you have placed yourself in a position where the enemy has advantage. This is essentially what Rep. Murtha has proposed: a tactical retreat and repositioning of our forces in such a way they are less exposed and able to respond to the enemy actions with greater agility. For that he's been called a cut-and-runner.

Still, I say we stay and finish it right. Our half-assed nature of messing things up and then leaving is what got us islamo-terrorism in the first place

Agreed. I think we have a moral duty to Iraqis to set things as right as we can possibly make them. But we must be realistic. Opportunities have been missed along the way, repeatedly. You can't keep doing that and not have your options narrow or your costs inflate. When we pull out, there will be civil war in Iraq without a doubt. I think it is tactically possible to avert this, but it won't happen. If the level of sacrifice needed to avert the mess we are in was too high, who knows what it would take now to fix things? Certainly more than we as a country will ever be willing to do in my opinion.

Best to reduce our exposure, and stop trying to pretend the inevitable won't happen. Then do our best to help them pick up the pieces.

I have also had the displeasure of working with Raytheon at a customer site where the group from Raytheon was more in line with your description of the LMCO employee you dealt with. I still laugh at a particular situation where they came to me and asked if I could reset all their passwords (including root) after they applied some updates to the system...fortunately I had been logged into the system prior to the upgrade. I don't think I would base my whole opinion of Raytheon on a few employees though.

If you find that the person you are dealing with is incompetent, just ask that the contractor consider providing someone with a little more experience. Large contractors do hire a significant number of fresh out of college employees so maybe you ended up with a "noob".

ICBM may end up being multi tiered, with orbiting lasers/brilliant pebbles in space, multiple rounds of ground launched ICBM intercept possibly with multiple methods (nuke vs kinetic) plus some air based laser systems as last resort.

Right now, I think only kinetic ground based is online, but the other star wars programs have languished in various stages of development.

Actually, the main criticism about postwar Iraq is its absence, since fighting is still going on.

What worries me is that the current attitude toward Iraq is a lot more like post-WWI attitudes about Germany than post-WWII. Today, people are war weary and want to avoid as much further interference in the middle east as possible. This is the same attitude that led to the highly popular, but ultimately costly and ineffective, appeasement policies toward Hitler.

Saddam Hussein is not the Hitler of our generation, although he might have been. Our Hitler will be some terrorist or dictator in the near future that will build up weapons of mass destruction unhindered because we don't want another Iraq war.

Post-war Iraq isn't yet safe...this is not a news flash, and it isn't surprising. I see you provide plenty of criticism, what is your suggested solution? What should the US have done differently after the invasion?

That's just the personal safety side of the issue. You've got intermittent power and water, the Sunnis didn't participate in the first round of elections so they are largely left out, the Kurds may split off and form their own state, a bunch of Shiites are trying to set up an Iranian-style theocracy in the South, and corruption in the government.

Even if this worst-case scenario plays out, we end up with three smaller countries and less of a security threat.

We've gotten rid of Saddam with his torture rooms and death squads, and now we've got a new government with torture rooms and death squads.

Do you have any kind of evidence that the new "torture rooms" and "death squads" come anywhere close to the scale of abuse that existed under Saddam? Do you know how many Iraqis died at the hands of his regime every year?

At least the new government isn't gassing entire villages of Kurds, or machine gunning thousands of people and dumping the bodies in trenches.

If this is success, God help us if we encounter failure.

The article you linked to is talking about a boost phase interceptor. The appropriate program for this is the "Kinetic Energy Interceptor," (KEI) not THAAD. THAAD is the "Terminal High Altitude Area Defender." Boost phase means while the missile is still boosting and going up. Terminal phase is when it is falling down on the target. THAAD is an amazing system. It will be able to shoot down short and medium range ballistic missiles both inside (endothermic) and outside (exothermic) the atmosphere. Well above the ceiling for Patriot PAC2 or MEADS. It is mobile, unlike GMD (Ground-based Midcourse Defense) which have to have silos to launch their rockets. It can defend a very large area, while Patriot and other low-altitude systems can only protect a small area. THAAD just passed a flight test last week. It will work.

Re:I was killed by Linux

[Anonymous Coward]

Ground based Midcourse Defense
They shoot down ICBMS outside of the atmosphere, around the time that it apogees. It is not a mobile system, needing very large multi stage kinetic interceptors to reach the required speed and altitude. GMD is already deployed, but I am unsure how many successful intercepts they have achieved. I remember a few test failures last year due to different malfunctions that kept the rocket from ever launching. Hopefully they have that fixed by now.

It would be amazing if it could be done, and I too would at least consider paying for a 50% effective missile defense. But it isn't 50% effective. It's 0% effective. We went ahead and built the part in Alaska at great expense without ever having a successful full scale test. What few tests there have been have been rigged to various degrees, and it has failed most of them anyway. The biggest real world success was shooting down a target missile that was carrying a radio beacon, broadcasting it's position.
I mean no disrespect to the engineers involved; they've done very impressive work. But the task does not appear to be achievable. Unless you consider that the task is to funnel money to specific campaign-contributing contractors & key congression districts. At that task missle defense has been a huge success. Meanwhile, ICBM seems like about the least likely way anyone would try to deliver a bomb to America.

Re:I was killed by Linux

It was the F-15 and it was called ASAT. It was never put into service but just tested. The US also had some very effect anti-satillite system based on the Nike Zeus/Spartan missile and the Thor.

Getting your town gassed by Saddam for political reasons is a totally different threat than "can't drive to the Baghdad airport without a convoy, or without being attacked by a U.S. convoy because I get mistaken for a car bomber." Guess which one pisses off a Baghdad resident more?

Plus, give them time. Once somebody solidifies power enough to eliminate general guerilla conflict, I'm sure they'll bring back the torture chambers and ethnic politics in full force.

And, don't forget to count the civilians killed during the U.S. invasion and occupation. They're just as dead as if Saddam killed them, and just as randomly and unfairly.

Step back for a minute and think what you are claiming. "At least we are not as bad as Saddam was in some dimension." Is "not as bad as Saddam" really how low the bar has been set now?

As for a different plan, perhaps a force more like the 300k troops to maintain order that Shinseki had discussed before he got shitcanned, without the pie-in-the-sky assumption that we'd be greeted with flowers, would have been a good start.

As you say, you'd have to be pretty stupid to think this was going to be easy, and right now it's going very nearly exactly as I expected it would.

Really? Then you thought from the beginning this would be one of the most one sided and painless military victories of all time?

Almost every anti-war pundit was screaming about "tens of thousands of American soldiers dead" in Iraq from urban warfare before fighting began. I guess you were more attuned to our military capabilities.

And for those of you who insist on comparing Iraq to Vietnam: in Vietnam over *50,000* soldiers were killed. We lost *thousands* of aircraft. We never defeated the enemy militarily, and we never occupied all of Vietnam. North Vietnam never had democratic elections.

Iraq is an amazing success compared to Vietnam, and anyone who says otherwise is a fool, and a tool.

Ah, I see. You're suggesting that Iraq is going to end up carved into two or more states who are mortal enemies. That they'll spend decades facing each other over frozen battle lines.

I think you've confused the current situation with the Iran-Iraq war. ;-)

That the fate of the region will remain in balance only through a combination of exhaustive militarization on either side of the line with the added threat of global nuclear conflict?

How exactly is this different from the pre-Iraq-war situation? Not a bit that I can tell.

On the other hand, there are some very hopeful signs such as the withdrawal of Syria from Lebanon, the reduction in the Libyan threat, and calls for increased democracy across the region. None of that would have happened without the conquest of Saddam's Iraq. So, I think your analysis is flawed...or intentionally distorted.

Re:I was killed by Linux

I don't see "victory" yet. As in "achieve the stated goals." Yes we cleaned up against Saddam's regular forces. Luckily, there weren't any WMD to be used on our troops. Now we're pinned down in urban warfare that is chewing our Army up slowly but surely.

"Not as bad as Vietnam in body count" is not equivalent to "victory."

As for democracy, what's the most stable democratic country in the Middle East, excluding Israel? Why, it's IRAN! Oh, boy. Good thing Iran is not a security threat. Someday, Iraq may be a Middle Eastern democracy, too! Now who's view is distorted?

I don't have the time now to make such a thoughful and respectful reply as you did (although I'll leave the respect in).

I don't see our situation as weak and in need of repositioning. Military targets are hard to get to, and the obstrucionist murderers are now mainly killing Iraqis. I don't see how US force repositioning can help them.

I also don't see a civil war as inevitable, that orientation is what really shapes our views. I just think that it'll take the comitminet of US forces for up to 10 years to really stabilize the country.

Sadam had fake elections too, that didn't make Iraq a Democracy. When you have an un-elected board that trims and picks those who are allowed to run (including the omission of many incumbants) it's a sham, not Democracy.

You have to go North to Turkey to find the closest Democracy in the region.

In Iraq the precision aerial bombardment technology did not protect innocent civilians from "collateral damage" as advertised.

LOL! You are totally clueless.

Do you have any idea how many civilians would have died in Baghdad alone if precision guided weapons *hadn't* been used?!? It would probably have been 100x more.

Precision munitions saved many, many civilian lives. That isn't the same thing as saying "No civilians were killed".

I put Turkey in the Near East; basically, Europe. But, I'll admit it is more democratic than Iran. Lebanon is a more ambiguous case.

Still, Iran is not a single-party sham like Baathist Iraq. Yes, it is seriously flawed, especially by Western standards, but their recently-elected president (and his predecessor) were elected in basically freely contested elections. You think Ahmadinejad was not democratically elected? Yet certainly he is not pursuing policies that are favorable to the U.S.

"I hope you realize that much of the criticism of postwar Iraq mirrors criticism of postwar Germany after World War II...and look how that turned out."

You know, I'm really sick of the World War II comparison. I'm not a historian and even I know it's bullshit.

First, in the Japan case, we kept the Emperor around. The Emperor of Japan, at the time, was the absolute power to the Japanese. If the emperor said, "Cooperate with the Americans", the people cooperated. If the emperor said, "We're now a democracy. Go vote," people went and voted. If the emperor said "Hop on one foot for the day," people hopped on one foot. You did what the emperor said.

Second, in the Germany case, you had a country that already had a democratic history. The people of Germany essentially elected Hitler as dictator. When the War was over, they had experience and trust in a democratic system. The people of Iraq have no such history. Also, the rebuilding of Germany was sort of the first steps of the Cold War--we had to show the people of the world that America, Freedom, Mom, Apple Pie, etc. were better than those godless commies. Again, the idea was to win the hearts of minds of the people of Germany. There was no such plan in place in Iraq.

Then there's the whole "rebuilding" thing. Who do you think rebuilt Germany? The answer, of course, is Germans via money provided by the US's Marshall Plan. In the end, you had German companies who owned their own assets. Who is rebuilding Iraq? Halliburton. And what do you have in the end? US Ownership of Iraq's assets.

"If Iraq doesn't have a democratic form of government in five years, THEN we'll talk about failed US policy..."

Ah, yes. A "democratic form of government."

Remember, Iraq had a democratic form of government before this. They had elections. Hussein won them--usually by large margins.

Re:I was killed by Linux

[Anonymous Coward]

We never defeated the enemy militarily, and we never occupied all of Vietnam.

And there are many areas in Iraq that are no-go zones. Occupy today, gone tomorrow. Essentially there simply aren't enough troops, so it's not the troops fault, it's the *#&(*%heads back in Wash. North Vietnam never had democratic elections.

Puhleez, don't call those democratic elections. That's purely for political purposes, once the troops leave, the real work will get done, hopefully some of the work will be useful, but highly doubtful. On the other hand, there are some very hopeful signs such as the withdrawal of Syria from Lebanon, the reduction in the Libyan threat, and calls for increased democracy across the region. Reminds me of the latest issue of the Onion - Bush calls for more hoping for a change Anyway, you've been watching too much Fox. Back to reality: Basically, that's all very nice 'maybes', meanwhile, Iran is building up Nukes, N. Korea's got nukes, we are massively indebted to China, a communist country. And any middling progress has been far far outweighed by the sheer idiocy of such moves as Flamegate ( treason), Abu-Garaib, Gitmo, secret CIA Gulags, burning corpses, napalming innocent civilians, threatening to bomb Al-jazeera, contractors shooting families on their way to the airport, etc etc. Basically the U.S. has lost whatever 'moral leadership' it had after WWII, squandered by some f'up from Texas and his lobbyist, oily pals.

None of that would have happened without the conquest of Saddam's Iraq. So, I think your analysis is flawed...or intentionally distorted

Uh, and you know how great things are because you've been to Iraq and seen for yourself? Thought so. Distortion is all yours, sadly. Wish it were a good thing. Wake up people.

Don't come back at me with "Hitler's Germany." Germany had multiple advantages that Iraq does not have

1) at least a history of the Weimar republic, dysfunctional as it was. Hitler had only been in power for 12 years.
2) a central part in the culture of the Enlightenment, great universities, and a tradition of first class technical and industrial development
3) "occupiers" who were culturally and religiously compatible with German norms
4) had become a country on its own, not from external forces, without a past of colonial subjugation.
5) No guerilla aftermath; occupation which was overwhelming in its presence, yet, in the Western sector, generous with reconstruction efforts.
6) A commitment from the U.S. and allies sufficient to maintain forces there for 50 years.

Re:I was killed by Linux

LOL! You are totally clueless.

LOL! You shoot from the hip too much. ;-)

Do you have any idea how many civilians would have died in Baghdad alone if precision guided weapons *hadn't* been used?!? It would probably have been 100x more.

Naturally. But while they are a great improvement, they still didn't work as well as advertised. Remember there were adminsitration officials talking about a "humane" war. And in relative terms the aerial phase of the Iraqi campaign may have been the most humane campaign ever conducted. But strict honesty, the kind that is employed in the field of science for example as opposed to politics, would admit that even a highly precise aerial bombardment campaign is not humane or harmless.

Precision munitions saved many, many civilian lives. That isn't the same thing as saying "No civilians were killed".

Indeed. Because you and I are having an honest discussion of this, we can both agree that this is so. I think we can both agree that since the Iraqis had deliberately situated military installations in close proximity to civilians, it's a very good thing we used precision munitions. I think we can both agree that it probably saved an enormous number of lives. I think we might disagree on whether it's a good idea then to make a great point of how are campaign was "humane". I also think it is extremely harmful to exaggerate the real world performance of systems, excellent thought it may be, because it depends so much on the higly fallible intelligence and target selection process. At the very least this convinces people that the inevitable civilian casualties are deliberate -- as in the Chinese embassy incident.

My basic point, which you did not address, is that even if one hundred times the civilians had been killed, it's important to remember that civilians will be killed in every phase of the war. Therefore it's very important to win quickly, because unending war means unending civilian casualties.

What I've been arguing against is the view that weapons system "A" is an unmitigated good because it is purely defensive. Or that weapons system "B" that blows people to bits or burns them horribly to death is inherently more evil because it makes us feel bad. Because if A is used to get into a war or to prolong a war, it will result in people being blown up or burned. If B is used to shorten a war, it will save people net. What I detest about this notion is that it stems from the wishful thinking that we can fight an absolutely humane and just war, and that giving into that romantic notion means that we won't get it over as quickly as possible.

Re:I was killed by Linux

Second, in the Germany case, you had a country that already had a democratic history. The people of Germany essentially elected Hitler as dictator. When the War was over, they had experience and trust in a democratic system.

Horsepucky. The German people had a terrible time under their "democratic" government. That's WHY they brought Hitler to power.

The people of Iraq have no such history.

Below you point out that Hussein was elected... Which is it?

Also, the rebuilding of Germany was sort of the first steps of the Cold War--we had to show the people of the world that America, Freedom, Mom, Apple Pie, etc. were better than those godless commies. Again, the idea was to win the hearts of minds of the people of Germany. There was no such plan in place in Iraq.

Also nonsense. We have a very large rebuilding plan in Iraq, designed to do EXACTLY what you suggest. It hasn't gone as well as hoped, mainly due to security issues.

However, the factor that you're conveniently ignoring that makes Iraq a much *easier* proposition than Germany in the long run, is the proliferation of Western culture and technology through the media. From what I hear the typical Iraqi teenager in Baghdad today is sporting a rapper T-shirt and talking on a cell phone. Satellite TV dishes are everywhere. McDonalds franchises can't be far behind. ;-)

Every government in the area is terrified of the effect of Western media on its citizens - and Iraq is now thoroughly immersed in it.

Things are actually looking quite good, depending on how things go through December 15. I'm highly optimistic.

Then there's the whole "rebuilding" thing. Who do you think rebuilt Germany? The answer, of course, is Germans via money provided by the US's Marshall Plan. In the end, you had German companies who owned their own assets. Who is rebuilding Iraq? Halliburton. And what do you have in the end? US Ownership of Iraq's assets.

Horsecrap again. The US can't afford to come out of this looking "imperialistic", so sadly enough we're absorbing the cost ourselves (well some is being borne by our allies, but not much). US companies won't end up owning much in Iraq, though there well may be some "sweetheart deals". I don't see a problem with that - better us than Germany, France or China.

The other thing you're missing is that Germany was quite poor at the end of WWII, while Iraq has vast petroleum wealth. Iraq won't need nearly as much help to succeed, it just needs a working government, industrious citizens, and a modicum of security.

Re:I was killed by Linux

[R3d M3rcury]

"Horsepucky. The German people had a terrible time under their 'democratic' government. That's WHY they brought Hitler to power."

The German people had a terrible time under their democratic government mostly due to rampant inflation brought on by repaying their war debts. They brought Hitler to power basically because they were sick of it.

"Below you point out that Hussein was elected... Which is it?"

Sorry. I was being a tad facetious. Iraq "elections" were not private and if you didn't vote for Hussein there was a good chance that you would have trouble later on. So pretty much everyone voted for Hussein so that they didn't have to worry about being shot.

"We have a very large rebuilding plan in Iraq, designed to do EXACTLY what you suggest. It hasn't gone as well as hoped, mainly due to security issues. [...] The US can't afford to come out of this looking 'imperialistic', so sadly enough we're absorbing the cost ourselves (well some is being borne by our allies, but not much). US companies won't end up owning much in Iraq, though there well may be some "sweetheart deals". I don't see a problem with that - better us than Germany, France or China."

Here's where we disagree.

Consider the Marshall Plan, again. We essentially gave money to German companies to rebuild. Take an example like BMW. With America's help, BMW became a leading auto manufacturer in the world and improved Germany's economy.

If we did what we're doing in Iraq with Germany, we would have payed GM to build an auto-plant in Germany and ask them to hire German workers. Sure, Germans would have gotten a salary out of it, but it wouldn't have made Germany into an economic powerhouse. The money that was made selling GM cars would have left the country.

The entertaining part of your quote are phrases like "Sadly enough." Your theory is that because the US liberated Iraq, Iraqis should allow us to set up their government so that it's beneficial to the US and US corporations? It's good for the US to be imperialistic, as long as we don't look too imperialistic?

Gee, and I'm sure you can't understand why the rebuilding hasn't gone "as well as hoped."

I hadn't heard of RedHawk Linux until this news blurb, so at first I thought I had read it as "RedHat" and just about choked on my coffee!

Re:w00t!

[Anonymous Coward]

RedHawk Linux is used in some high-end applications. It is provided by Concurrent, a company which also offers several different hardware solutions that work with the Linux offering.

Re:w00t!

[wde]

Our group has one of the Concurrent "iHawk" systems on order. They're pretty sweet. Essentially, RedHawk is a Concurrent-licensed version of Montevista's HardHat Linux modified to have its scheduler driven by a Concurrent-custom hardware interrupt card (the "RCIM"). You program your interrupt frequency, tie your task to be driven by the card, and determinism goes through the roof. The computer itself is COTS server-grade stuff. Presently Concurrent is using Dells I believe.

well I couldnt see picking windows for such a thing..."so the rocket just launched....uh-oh....we just got the BSOD....is that bad?....umm...nah...*ducks under desk"

Re:w00t!

[Anonymous Coward]

RedHawk Linux is based on RedHat Enterprise Linux 3 (as of RedHawk 2.2). RedHawk's kernel modifications are implemented as modules (without source) which are installed on top of a RHE 3 installation. A Dell server with the RedHawk OS is sold as a "NightHawk" system.
I used Redhawk extensively at my previous job (another major DoD contractor) to develop a similar simulation system (aircraft rather than missile). Good system, my main complaint was that the API was a bit kludgy, and the documentation wasn't up to standard for the price (NightHawks are _far_ from free). The resulting system, however, was rock solid.

Re:w00t!

[Jah-Wren Ryel]

You program your interrupt frequency, tie your task to be driven by the card, and determinism goes through the roof.

What if your program needs to do I/O? He has to hit the kernel for that, won't that just blow any sort of guarantees for a timeline? Aren't there a bunch of locks that may or may not be locked already through any system call that will do I/O?

Re:w00t!

[Anonymous Coward]

RedHawk is not necessarily faster or more inherently deterministic than the stock Linux kernel. RedHawk's value-add is in the increase in determinism of programs using the frequency-based scheduler. Essentially, a program configures an fbs (frequency-based scheduler) and enters a loop, at the beginning of which it calls fbswait(). fbswait() wait returns when the frequency-based scheduler decides that it is time for that process to execute again. If any process doesn't call fbswait() in time, an overrun has occured, and overrun handling code can be executed.
You are correct - an IO intensive process that does not carefully manage time will overrun and cause nondeterminism. However, using RedHawk and the NightStar tools, you have better visibility into what processes are causing the lag and when, making it much easier to isolate and deal with problem processes.

Re:w00t!

[Anonymous Coward]

Back in the day, Harris sold a computer called a NightHawk. Up to 8 Motorola 68K processors. The ones we used ran CX-UX from, wait for it, Concurrent. The selling point was that it was a hard realtime operating system -- very useful when you're doing realtime hardware in the loop simulation with avionics.

Re:w00t!

Yep. That's the million dollar question and I can't answer definitively until after December 30th (when our box arrives). I/O has always been a stickler with real-time apps. Concurrent does offer engineering services to integrate approved I/O cards into their real-time OS and we've taken advantage of that. Real-time I/O for us will be restricted to D/A-A/D via a General Standards card which appears to use memory-mapped registers (reading the manual right now). I'm sure the iHawk has limitations as does any system but it's magnitudes beyond the plain vanilla 2.6-linux-on-a-PC approach.

Only to the degree that I don't like the idea of any technology being used in war, or any people being harmed as a result of war.

However, as of today there is no practical solution to the generalized problem of war that does not include actually fighting one somewhere in the decision tree. Within that hopefully narrow scope of contingencies, it behooves us to fight the war effectively and finish it quickly. In the run up to Iraq, my hawkish friends thought that somehow our precision military technology would allow us to prosecute a new kind of "humane" war. I thought this was an infantile militarist fantasy, in which we could throw our military might around but still be "good guys". While I agree it's a good thing that our technology reduces "collateral damage" (innocent people harmed), I think it's much more important that this technology allows us to get it over with quickly.

War is in my view always a calamity. A longer war is necessarily a greater calamity.

This is not "real-time" application. This is hardware-in-the-loop simiulation. Moreover, not only is Linux inappropriate for real-time primary defense system.. it is generally strictly prohibited (almost uniformly) by military specification because it is not a true real time operating system. Back at the old job, VxWorks variants were most common.

Re:To all the naysayers...

[Glock27]

This is not "real-time" application. This is hardware-in-the-loop simiulation.

HIL simulations are hard realtime applications. Do you even know what the definition of "hard realtime" is? In a nutshell it's "If a task fails to run at it's scheduled time, it's a fatal error.". Soft realtime means it's not a 'fatal' error if the task schedule isn't met (i.e. a dropped frame in a game).

Moreover, not only is Linux inappropriate for real-time primary defense system..

Baloney.

it is generally strictly prohibited (almost uniformly) by military specification because it is not a true real time operating system. Back at the old job, VxWorks [xs4all.nl] variants were most common.

Also not true. Linux (with an appropriately modified kernel) is in fact a "true" realtime OS. Here's a list of military projects using Lynuxworks (only one flavor out of several).

This page has a good description of the Lynuxworks product, along with some RT certification information.

WindRiver is also offering Linux, though I see their version isn't RT capable. Guess they still haven't figured out that vxWorks is on the way out...

(BTW, I'm a certified vxWorks developer myself...)

Feel any good for building weapons?

[Anonymous Coward]

So we can conclude that the open source effort that has contributed so much to Linux, is the same effort that has built weapons of mass destruction.

All the people who contributed to the Linux project can now assume that they have taken part in building weapons that kill real people. Do you feel any good about this? I would if I was a contributor.

Re:Feel any good for building weapons?

Don't be stupid. The GPL states that Linux may be used for any purpose the user sees fit. That can be good or bad. Things to note:

1. People do bad things using Linux on a daily basis including cracking, handling violent or child pornography, sending spam, and writing unpleasant messages to people.
2. War happens so get over it. Kernels don't make war, human nature and the tendency of agressors to wind up in positions of power do. If Linux provides better accuracy that allows us to moderate destruction and keep it to strategic targets, then that is a good thing.

You really cannot be serious "all the people who ... have taken part in building weapons that kill". They didn't build weapons, they built general purpose software. They can have completely clear consciences about this. Don't let one application of this software politicise Linux or the Free Software movement in this way.

It's not like they were going to scrap the missile defense system just because there was no Linux OS.

There are always other choices. If Lockheed has a contract, they are damn certain to build a missile defense system. Would you feel any better if they spent millions of taxpayer dollars to build an OS from scratch -- probably crapware from land of offshore/outsourced bargain buddies?

Who needs a missile defense system that gets infected with the Sony rootkit just because someone popped a music CD into the drive?

Re:Feel any good for building weapons?

[jc42]

... like saying that the inventor of the hammer contributed to violence and killings.

This has been a constant objection to all advances in knowledge throughout hiistory. It's hard to think of any technical advance that can't be used for both bad and good.

And strictly speaking, it wasn't really the inventor of the hammer that enabled more killings. Rather, the "basic research" that led to better hard-material devices (chipped flint, forged metals, etc.) led to the artisans makng both better tools and better weapons. Some of them (blades, hammers) could be immediately used for both good and bad purposes. Try building your hut or grinding your grain or carving up your deer without a good hammer or quern or knife.

Now that so much of our technology includes software, it's not surprising that the same principle applies. Anyone working on low-level software (OS kernels, runtime libraries, comm systems, whatever) will inevitably find it used for both bad and good. Many of us who foisted the Internet on the world are not at all surprised to see it spin off viruses, phishing, and RIAA lawsuits against children and grandmothers. In fact, we discussed such things long before they arose, but we didn't ever find a way to prevent them.

The problem is that, like knives or hammers or gunpowder, software really can't distinguish bad from good. That can't be done with any of our current technology. We have to use social methods for handling bad/good distinctions.

We won't stop killing by taking away bombs or guns or knives or OS kernels; we can only do it by taking away the social and political structures that support and encourage the killers.

Given that we had to migrate, the best option was to migrate to a free OS. Linux is likely to be around a lot longer than a commercial unix. And if it comes to the worst we can maintain it ourselves.

Re:Unlimited Budget and picks Linux...Wow!

[Kadin2048]

Actually, this isn't the DoD, it's Lockheed Martin, a private company which does business as a government contractor. Although I claim no knowledge of their finances, I'm willing to bet however that their budget is definitely not "unlimited," although it might be large compared to what you and I are used to. Especially if they are on a fixed-price contract, where their total revenue has been specified in advance, the employees are probably under a lot of pressure to keep costs down since every dollar they spend eats into their profit.

I think in this case though there wasn't much competition, at least of the Linux/Windows variety, since Windows doesn't really do real-time applications very well apparently. I'm not actually sure what the other options would have been besides Linux for a project like this: I can only assume that there are some highly proprietary, niche-market OSes for this sort of thing, but that in general the COTS field is pretty limited.

Re:Unlimited Budget and picks Linux...Wow!

So why wouldn't I want all that fame and fortune? One simple reason: Negative publicity. Yes, negative. How? Well, simple.

What if the system were to fail?

Now, I'm not badmouthing Linux or anything here – especially not my own system ;-) – but even the most stable distributions can crash. For example, all my systems run my distro, which is for the most part a very highly customized Slackware. Well, Slackware's legendary for its stability, and for the most part everything runs just fine, but it can still be brought to its knees, say, if I decided to pull up a really CPU-intensive and potentially dangerous program such as Mupen64 to play Mario Kart without having to walk downstairs to my N64. It usually does just fine, but if it goes down, the entire system soon follows...

Just something to think about if you suspect that you may be the next RedHawk ;-)

Re:But what if...

[glaswegian]

However if you were to stick to the more stable applications on your stable Slackware box you would have fewer (or no) problems. I imagine that the software that will be running on the missile defense computer(s) will be more thoroughly tested than some dodgy game port coded by someone during their spare time.

Saying that, if there were a problem it would give windows fans endless amounts of ammo to gun down Linux (sorry for the pun).

You do have a very good point there, one which is worth noting. I will admit that a game emulator and a missile defense system are two completely different tasks so it wasn't the best comparison, but what do you expect from something posted in about a minute before I had to leave for school?

For the record, most of the programs on the system are highly stable, tested versions, and anything that I don't like doesn't go on. For example, unlike most Slackware derivatives I still use 2.4 – I've had some really nasty experiences with 2.6 before – and all the other stable choices Slackware seems to prefer.

The point I'm trying to make here is that no software, no matter how tested and stable, is bug-free, and accepting an offer to run your distribution on such an important system where failure is not an option is a very big responsibility. What I'm trying to say (and I should have worded it better earlier, I know) is not that I'd turn down any hypothetical offer on the spot, but that I would want to give it very serious consideration because even though it hopefully won't have any problems, there is still a slight possibility of failure, and we don't want another Mariner 1 now do we?

It's not that liberal. Most conservatives think the same way.

Certainly not getting killed is a very good motivating factor to develop new technology but I'm not sure that is the sole reason for the spikes in creativity. More accuratly I think we could see the same spikes in creativity without the need to go to war.

Eh? I hear you say. Well look at it like this. The people that take a country to war are normally loud mouths. Most of the time they bang on about going to war and making money. When they get their way and end up at war they start spouting about needing new and better weapons. Money and or resources get diverted to research and new things emerge. They used the war as an excuse to divert the money / resources. The war didn't cause the innovation the resources did. Ergo we could create that spike in innovation by diverting money any time we wanted and, better than that, we wouldn't have to bear the cost of the war either meaning that the boom in innovation could last longer.

That's a logical fallacy that imbues scientists with the power to make discoveries and advances on demand. Technological advances occur based on the availability of scientists, raw materials, pre-cursor technologies and excess wealth to piss down many avenues of fruitless research so that one day the right solution 'may' be found. Once these technologies are discovered it may take some time for them to find uses in various aspects of a society's life including war. For example flight wasn't initially invented in search of war and neither was the phonograph/grammaphone invented in order to distribute music records to the masses.

When wars occur over the usual squabbles over limited resources advanced civilizations usually overcome less advanced civilizations. That is, it's best to think of technology's use in war as one thinks of evolution: the zebra didn't will itself to grow a longer neck over many generations but just that the zebras with longer necks ended up eating more and producing more offspring.

The rise and fall of human societies are governed by the same evolutionary processes as those that govern microbial societies.

"availability of scientists, raw materials, pre-cursor technologies and excess wealth"

were forced into use during the war. This led to immense technological advancement, pretty much on demand (or as close as you can get in science) despite your erroneous claims to the contrary.

Re:One day

count the number of allies, the number of tons of resources they had access to, the number of people they had access to and the relative land areas they controlled and their distance from the axis powers. Now do the same for the axis powers. The axis powers had far fewer resources , people and were not even in striking distance of USA, Canada and South America while both sides were even in terms of technological advancement. Once the war started america entered unscathed by the devastation in much of europe and also possessed native reservoirs of oil in the midwest which germany did not have access to. No stellar advancements were made in this era. The technologies used in that war were refinements that had been in development ever since the end of world war I. Germany ultimately failed after they ran out of fuel oil for their blitzkriegs when then they were stone walled by the russians with a great loss of personnel on both sides.

It is quite obvious you are unfamiliar with the details of the war and of the major turning points that led to the defeat of the axis powers.

Technology did not win ww2 in europe and new technology was not produced on demand. A few nacent inventions were refined over the course of the war and put into use as time and resources permitted.

Cryptography won the war basically. More accurately cryptoanalysis. If you want to get really technical the Poles won the war. As more information is declassified about just what was being done with Ultra it becomes pretty clear that was deciding factor in not only most major engagements, but the overall war plan of the allies. Granted, we do not know what would have happened if the Allies were fighting blind, it is possible they would have made the same tactical decisions and the outcome would have been the same, but that does not seem likely. There is always disagreement as to the final impact of intelligence in WWII, I happen to believe it was of pretty significant importance.

The technologies used in that war were refinements that had been in development ever since the end of world war I.

Literally all advancement in just about anything can be described this way. Certainly the war did not magically cause miracle advancements, but it kicked into high gear a lot of promising work that bore fruit much faster than it otherwise would have. The Atomic Bomb (leading to tons of nuclear research), early computer technology, radar, jet aircraft, etc. were all basically products of WWII. Going back further than WWII, you see that war (or more accurately survival) has been a primary catalyst for advancement in many fields.

Germany ultimately failed after they ran out of fuel oil for their blitzkriegs when then they were stone walled by the russians with a great loss of personnel on both sides.

Germany's resource problems did not really emerge until well after they had lost on several fronts in Europe, including Africa, Italy, and much of France. They didn't really have a problem until late in 44, leading to their abandonment of the Russian front (effectively) and focus on capturing Allied resources in their ill fated final offensive (battle of the bulge)

Re:One day

[prurientknave]

Allied cryptanalysis techniques involved finding both the enigma machine and the code sheets from a submarine and collections from other human intelligence assets. This let them have full access to german military communications. humint and dumb luck are hardly astounding technological advances on demand. The atom bomb's initial idea was circulated since about 1910 the problem was a lack of refined uranium and lack of political will to fund such a test before the war. The war added the missing ingredients but the refinements came too late to be used in the actual war in europe and was only used as a field test on a broken oriental enemy that had already been firebombed into oblivion.

Can we stop fighting the Cold War?

Missle defense is a waste of money. Apart from the fact that the progress on the systems hasn't gone well after this many billions of dollars, the usefulness of a boost phase missle defense system is questionable at best. It won't stop attacks from what is now the most likely vector - terrorist attack via smuggled weapons.

Many people bring up Iran or North Korea as possible threats. Perhaps, but apart from the fact that they're years away from having missles that can hit the US, the more sensible tack would be to build a launch phase system that could be parked near a threat country. The system would be easier to construct given the shorter range for the interceptors to travel to target, the targets are moving more slowly, and there are fewer targets since any MIRVs haven't reached the point where they independently target. It'd be smaller and cheaper, and much more practical to do that.

Of course, then, we wouldn't be able to pay out so much money in corporate welfare to defense contractors.

Missle defense is a waste of money.

Who else is going to pay for this type of pure research? Most shareholders and other commercial ventures will avoid R&D that does not have a short term ROI. The problem the military contractors are trying to solve are hard - essentially shooting down a bullet with another - and if you look beyond the star wars hype, it would be good to have some of those technology bits that will come out of this. The military is willing to pay an astronomical sum to keep an advantage over their opponent, so the money will be spent regardless. At least with the defense contractors, it is more of an engineering exercise than market driven fluff. Not that it is a huge solace.

I look at this research and see a better gyroscope. Look at the ring laser gyroscope technology that started as military kit, then worked its way into commercial aircraft. I would love for this to become such commodity stuff that I could put it cheaply into a homebuilt aircraft. Here is to hoping, anyhow...

This is a theater-defense system - it's a high-altitude defense against ballistic missiles such as Scuds and the like. It's not designed as a defense against strategic weapons.

Really, your complaint makes almost no sense at all - whatever weapon you're objecting to, it isn't THAAD.

Re:Yeah, but it's still a stupid waste of money

[kaiser423]

Huh, it's odd that you're attacking the THAAD system. It's probably one of the more useful systems in the whole MDA (Missile Defense Agency) program. I can see people whining about some of the other interception schemes, but THAAD can be very, very useful.

For example, say China is threatening Taiwan. Say North Korea is threatening Japan (or some other country). Take an Aegis group out there, fully armed with THAAD systems, and park it in the ocean between the two. Now, we can sit there and try to force talks, because with that fleet in the ocean, we can guarantee (to some amount of reliability) that the fight can't escalate TOO far. At least the smaller side doesn't have to immediately capitulate to threats via nukes.

Basically, the THAAD system is a mobile THEATER based defense system. It's meant for diffusing extremely tense situations between two nearby countries. It's a very useful capability to have -- immediate de-escalation since the biggest threats are now mitigated.

Complain about MDA all you want, but the THAAD system would find it's usefulness proven even without the current political climate, and without Bush's current push for missile defense. It's just plain useful to have.

Re:Yeah, but it's still a stupid waste of money

[Kadin2048]

You do realize I hope that this system, THAAD, is a theater missile-defense system, not a global "Star Wars" hemisphere-defense one.

It's designed to protect strategic assets from medium range, single warhead ballistic missiles, which are exactly the thing that China, N. Korea, and other ex-Soviet client states have in spades (and are significantly easier to put together than an ICBM). The intended use is to place them as a spot defense over a high-value target, as the farthest reaches of a layered system that includes short-range defenses like Patriot, etc.

This is not an ICBM shield for the U.S. in the manner that I think you are thinking it is, that would really have any effect in the event of a global thermonuclear war. The preventative measure against that is still MAD. However when you step down from that scenario (and terrorism), the next most likely case of a nuclear weapon being used against us is with a theater ballistic missile against a strategic target like a foreign city, aircraft carrier, or air base. In a situation like that, a defensive system like this makes a lot more sense.

Re:Yeah, but it's still a stupid waste of money

It won't stop attacks from what is now the most likely vector - terrorist attack via smuggled weapons.

Boost phase missile defense will discourage Kim Jong Il and Mahmoud Ahmadinejad and others from even trying to develop strategic nuclear weapons. It is also indispensable considering the ever increasing role of tactical misslles on today's battlefield.

Many people bring up Iran or North Korea as possible threats. Perhaps, but apart from the fact that they're years away from having missles that can hit the US,

Mr. Kim has already lobbed a missle over Japan. He can already reach the Aleutians. Why not deal with the gathering threat?

the more sensible tack would be to build a launch phase system that could be parked near a threat country.

I agree with this. Patriot batteries already provide this kind of defense. You can bet they are already deployed in Japan, South Korea, and Taiwan given their proximity to the crazy Mr. Kim and a bellicose China.

More info on RedHawk?

Does anyone have any more information on RedHawk Linux? I went to their website and it appears they modified the stock Linux kernel to make it hard realtime.

Any ideas on how RedHawk is able to make these claims?

Well, if you're interested on hard real-time simulations in general, check these guys out: RTAI. They've been around for a long time too, so you shouldn't be so scheptical of the linux kernel being modified to be hard real-time.

It's free (as in freedom AND beer), and it works pretty well, especially with I/O cards that are supported by comedi drivers, which are designed with real-time use in mind.

We use them for our real-time HIL simulations at my department, and we're happy with the results.

Re:More info on RedHawk?

I don't know any specifics on Redhawk, but I can say without a doubt that they know what they're doing and have a lot of history.

HWIL = Hardware In the Loop

[everphilski]

Hardware In the Loop testing is where a missile is put basically in a 3 axis gyroscope mount so it is able to maneuver freely. In front of it is put a projection screen where RADAR images are being projected. The seeker on the missile then sends a signal to the fins to move but instead of moving fins that signal is hijacked and an algorithm figures out how the missile would have rotated in space and instead rotates the gimbal (the gyro mount) instead. A computer program tracks how the missile would have really moved in space. A RTOS comes in handy for these kinds of simulations. HWIL testing is an important step between pure software simulation and firing the actual beast because you can start to see lags in the system and test indvidual subsystems non-destructively without ever firing a missile.

Gosh.

...a missile is put basically in a 3 axis gyroscope mount...

The THAAD missile it 20 ft long and weights a ton, putting it in a gymbal would be expensive and pointless because...

...projection screen where RADAR images are being projected...

This is wrong on so many levels. First of all, how does one "project" a radar "image"? Second of all, the THAAD radar is ground-based, not part of the missile. The vehicle is steered to the projected intercept point by commands from the ground. The kill vehicle steers itself to the intercept with an IR seeker.

Maybe the KV hardware test article is gymbal mounted but again, how does one "project" an IR "image" on a "screen"?

...sends a signal to the fins...

THAAD is exoatmospheric. Fins would be useless. It uses vectored thrust.

...A computer program tracks how the missile would have really moved in space...

See now, if you are modeling the dynamics of the vehicle, why bother actually physically moving it? In this case, you aren't testing the vehicle dymanics, you are imposing them, the only purpose of which would be to exersize the seeker mechanisms (of which the missile has none.) Why not simply vary the seeker's simulated target signal (what you call an "image" projected on a "screen" but which is probaby purely electronic)?

So which of you just revealed Military Secrets because some yahoo got confused as to the particular HWIL test for this particular missile?

The gimballed HWIL system is how my old boss tested the sidewinder. You put the fully constructed missle on a mount, and point it at a wall that looks and acts like a TV, but apparently also does IR as well as visible light, since the sidewinder is heat seeking.

From what he says, the point is to shake the missle up enough that the insides come loose and see what it does when that happens. If it still hits it's mark while being shaken apart, then it's ready.

Re:HWIL = Hardware In the Loop

[Frank T. Lofaro Jr.]

First of all, how does one "project" a radar "image"?

That's classified.

Re:HWIL = Hardware In the Loop

[Sinical]

I make HILs.

You don't need the whole missile. You need the guidance electronics and the seeker. I've seen THAAD's HIL.

Yes, you absolutely can project IR imagery. Look for the word "mirror". You can make mirrors that are RADAR transparent. I've seen them.

I don't the details of THAAD, but for the lower stages (since they simulate from launch), you intercept fin commands and use that information within a simulation to calculate updated attitude and position information. This is then used in returning data to the missile (altering IR imagery, etc.).

For the upper stage, they can detect the commands to set off the little "poppers", and they jitter the image with a high-speed mirror. They adjust the position, too.

For my missile, we don't feel a HIL is necessary: we will inject everything, including the video, and fully simulate the inertial measurement unit (IMU). But what if the Army wants to take a missile out of its container and test it? You can't tell them to take the whole damn thing apart, but you can usually get them to take the motor off. Then it goes in the table. It's not strictly necessary, since you can provide modes and still simulate everything, but they have millions of dollars and it gives them warm fuzzies, and they are the customer.

For THAAD, they may have rate sensors on their seeker that need to be fooled by putting them on a table. They may want to combine real and synthesized IMU data (real data for rates, synthesized data for unsimulatable acceleration (gravity, thrust)). Javelin and AIM-9x have to do this for various reasons: I'm not sure of them all. I think Javelin has *no* IMU: because it's lock-on before launch, you can figure out how you're moving based on how the seeker gimbals are pointed. Something like that.

You do HIL tests to make sure things work. For the early models, you want to make damn sure your seeker is good before you shoot off a $1 million missle in a test that costs $30 million (range time is *damn* expensive, and THAAD can only use White Sands cuz they shoot so far). In general, including as much of the flight hardware as you can is good. If you can't mount the CAS on the 3-axis (or whatever: I've seen up to 5-axis (3 for missile, 2 for target (no roll)) table, then you can put it on the floor in a test fixture and apply torques to the fins to simulate pressures and stresses. Depends upon what your requirements are.

In general, though, you use what we call a CIL: Computer-in-the-loop. No seeker: imagery is all injected, no IMU: all simulated, etc. This is purely for flight software and electronics hardware check out. I make these, too.

Re:HWIL = Hardware In the Loop

[Anonymous Coward]

20 feet = 6 m, it can't really be considered as big amd 1 ton is not heavy, a std. 20 ft. container may have a gross weight of 15 tons.

Radar is based afaik on electromagnetic radiation (and so is light btw.) sending a radar image is sending the echoes... and it does really not matter if the radar is ground based when you are testing the whole system.

Fins or thrusters is the same... the point is to intercept the signal and move the gymbal.

There may be equipment on board measuring the position of the missile.

This is a very cheap way to test all systems.

This is to prevent a hot war with China.

[Flying pig]

That the long term threat will be China, and your close launch system will not apply.

Mod this how you like or not at all, but when a competitor arises for a dominant superpower, the result is war. The Soviet Union never really competed with the US where it counted; the theatre wars in Afghanistan and Vietnam did not threaten the US (and Europe) the way Chinese power and hegemony over the Far East will. I am sure that the planners in the Pentagon have been replaying WW3 for years, and this program is part of what has come out of that.

Re:This is to prevent a hot war with China.

[Waffle Iron]

That the long term threat will be China, and your close launch system will not apply.

Trying to build a missile defense system to counter China is futile. China has the resources to build enough ICBMs to overwhelm any possible missile defense, and we're sending them $Billions more resources every quarter in exchange for trinkets.

Given that it costs orders of magnitude more to defend against an ICBM as it does to build one, they would ultimately win any ICBM defense arms race. Not to mention that countermeasures against the defense system are trivial, it's questionable if these systems even work properly without countermeasures, and it would only take a handful of intercept failures to cause devastating damage to the US. All such a deployment would do is prompt China to crank out more nukes. We would not be one iota safer than we are today after that happens.

Re:This is to prevent a hot war with China.

[Anonymous Coward]

You do know that the Chinese pay our govement's bills, right? They don't need nukes to bring us down. All they have to do is stop loaning us money.

Re:This is to prevent a hot war with China.

[AJWM]

Given that it costs orders of magnitude more to defend against an ICBM as it does to build one,

That's far from a given. There are many ways to interfere with an ICBM attack, THAAD is just one, and is one of the last resorts if other methods (airborne laser attack on the ICBM booster, coast-phase interception, etc) let something through.

The point, though, is that it messes up the attacker's planning. He can no longer count on every ICBM (less normal malfunctions) getting through, he has to figure that only some percentage will get through, and some targets may not be hit at all. This raises the stakes considerably -- a knock-out first strike becomes impossible, unless one is willing to spend the money on enough more ICBMs (or to toughen them up to resist counter attack) to again give the attacker overwhelming odds.

Not to mention that countermeasures against the defense system are trivial,

Right, don't mention that, because it isn't true. That canard was trotted out in the 80s, and some of the suggestions were positively ludicrous. (For example, it was suggested that defending against boost-phase laser attack was simply a matter of "spinning the booster". Consider the dynamics of a rapidly rotating cylinder of liquid fuel (as were Soviet ICBM boosters) on top of normal launch stresses. No laser required, the thing would probably disintegrate of its own accord. Decoys? Yes, please! To fool modern sensor technology, the decoy has to be roughly the same shape and mass as a real warhead -- so every decoy launched is one less real warhead for a given launch capacity.)

The cold-war defeat of the Soviet Union was exactly for this reason: they couldn't afford the spending to maintain their ICBM force at their desired threat level in the face of the various defensive strategies.

Now, you have a valid point with "we're sending them $Billions more resources every quarter in exchange for trinkets", which certainly wasn't the case with the Soviet Union. We could hope that this raises the standard of living of the Chinese to the point where they feel they have too much to lose themselves to start a war, but given the totalitarian government, there's no guarantee. Meanwhile, given a choice, try to avoid buying Chinese goods. (Yeah, good luck.)

Re:This is to prevent a hot war with China.

[Waffle Iron]

This raises the stakes considerably -- a knock-out first strike becomes impossible

China doesn't currently have a first strike capability anyway. Why drive them towards that direction? With their current posture, all they need is for some percentage to get through to deter us from doing an Iraq on them.

Right, don't mention that, because it isn't true.

It is true. There are literally hundreds of possible easy-to-implement countermeasures, and we have no idea what combination they might try. These missile defenses don't properly work today even under the laboratory conditions they're tested under, much less in the real world with evasive features tacked on.

The cold-war defeat of the Soviet Union was exactly for this reason: they couldn't afford the spending to maintain their ICBM force at their desired threat level in the face of the various defensive strategies.

The USSR couldn't afford their own missile shield, which would have been ridiculously expensive. We couldn't have afforded it either. China is not going to be making a missile shield for the same reasons I stated above. All they have to do is crank out some more missiles, which are relatively cheap. The current situation is not like the old cold war.

Re:This is to prevent a hot war with China.

[AJWM]

There are literally hundreds of possible easy-to-implement countermeasures,

Describe ten, along with an assessment of their impact on both the launch vehicle and the defensive systems. Come on, if they're easy to implement I'm sure that will be easy to do. I'm only asking for less than 5% of what you're claiming ("hundreds" implies at least 200).

Re:This is to prevent a hot war with China.

[Waffle Iron]

1. Launch a couple of extra nukes and explode them in the ionosphere just ahead of the real missiles. There won't be time to intercept them before they go off. It will be kind of hard to operate radars with all the plasma disruption. Handling this scenario can't be tested for, and any good engineer knows that something that's not tested isn't likely to work.

2. Give the warhead heat shields a good liquid nitrogen wash just before launch. They'll be a just a little hard to spot with infrared sensors. By the time they hit the atmosphere and warm up again, you're going to have just a minute or two before it reaches the target. Little impact on launch system other than a little plumbing.

3. Toss a few dozen flares out with the warhead. More problems with infrared sensors. Flares weigh almost nothing.

4. Cold gas thrusters constantly jostle the warhead back and forth randomly by a few yards. Kinetic interceptors wouldn't have much chance. It's a little bit of engineering, but it's standard spacecraft technology.

5. Release a bright cloud of vapor or dust around the warhead. It will be hard to pinpoint in the glare. Not much harder to implement than strapping an aerosol can onto the payload.

6. Spin the warhead around a small counterweight on a long tether. Once again, hard to hit. Harder to implement, but it's been done with satellites.

7. Inflatable decoys. Simple to implement.

8. Real decoy missiles with inert warheads, with identical mass and external materials as actual warheads. Relatively expensive, but much cheaper than adding more interceptors and command structure on the defense side.

9. Strobelights and radar transmitters on the warheads broadcast noise signals. Likely mess up delicate tracking systems designed to look for feeble signals.

10. Lots of cheap decoy rockets that simulate only the boost phase of real rockets. Defense systems would have a lot of sorting out to do before trying to locate the actual targets.

I could go on and on. How about you prove that not a single one of these or any combination of them would impact the effectiveness of the defense systems?

Re:This is to prevent a hot war with China.

[AJWM]

Those are pretty damn funny! I note you didn't discuss the effect on the launch vehicle, i.e. the engineering effort to get some of your gizmos to actually work.

And none of your techniques (save the last, sort of) address boost-phase intercept (eg by airborne laser or orbital-based kinetic interceptor.)

1 - That will nicely fry the rest of the attacking missile fleet electronics and the neutron pulses may well mess up the fissionables in them. You basically have the attackers do a self-inflicted Spartan/Sprint (look 'em up) defense on themselves.

2 - Warhead heat shields fail from thermal shock, warheads disintegrate on reentry. And, lookdown sensors from satellites see very obvious cold spots against the warm background of Earth and relay the coordinates. And, the LN2 plumbing (and LN reserve) reduce the payload, thus range, of the LV.

3 - Again, multiple sensors in different locations have no problem differentiating flares from RVs, and the weight of the flares and ejection mechanism reduce payload/range. Flares do NOT weigh "almost nothing", neither does the ejection mechanism. If they do weigh almost nothing, they'll lag behind the RV as soon as it hits upper atmo.

4 - Only "a little bit of engineering". Clearly you're no engineer. It adds weight (reducing range and payload), it really messes up targeting (oh well, if the nuke targetted for Los Angeles detonates in Death Valley, no big deal). Some of the designed and tested kinetic interceptors deploy to a rather large structure a lot bigger than "a few yards".

5 - Clouds in vacuum disperse pretty damn quickly, both from internal and sunlight pressure. And the denser LV will soon leave the cloud behind in the extreme upper atmo. Besides, the cloud disperses predictably, so we just have a bigger target for the interceptor to aim for the center of. (If the cloud is dispersed directionally, again you've messed up the warhead trajectory and targetting.)

6 - Now that really messes up the targetting, especially if the tether breaks (or is broken by the interceptor). Deploying it is no engineering triviality in the few minutes of ballistic coast that the warhead has, either.

7 - Inflatable decoys are trivial to differentiate from the real thing, even if you manage to give them the same thermal characteristics (careful choice of materials, paint, etc) they react differently to sunlight pressure, atmospheric drag (even very tenuous), or being pinged by a laser beam.

8 - An intercontinental missile is always going to be more expensive than a much smaller interceptor. You need to add in launch and command infrastructure on the attacking side, too. If you go the cheap route and base your decoys at obviously non-nuclear missile launch facilities (consider the relative security and command and control infrastructures), then the defender can ignore missiles tracked as launched from those sites.

9 - Yes please! That greatly simplifies the interceptor's job -- just home in on the strobe lights and radar transmitters.

10 - Again, rockets launched from known decoy sites can be ignored. If you want to convincingly make a decoy site look like the real thing, it's going to cost as much as making the real thing.

Nobody is claiming that a missile defense would be 100% effective -- any more than a bulletproof vest is 100% effective. But if someone is going to be shooting at you, you'd probably want one. Further, protective gear (or missile shields) are effective against accidents or single (or few) shot attacks.

Nothing is going to significantly protect against an all-out attack (although the severity can be reduced), the only hope there is to discourage the attack from being launched in the first place. This is much easier to do if the attacker knows that a significant portion of the attacking missiles won't make it to their targets, and that he cannot prevent a certain, devastating retaliation. Ultimately the potential attacker has to be convinced that he has more to lose than to gain by attacking.

Re:This is to prevent a hot war with China.

[Waffle Iron]

Blah blah blah. As I said, the defense system probably doesn't work anyway. There is little evidence that the tests done so far haven't been rigged, and many of those haven't worked. All it would take is the tiniest change to make ensure that it doesn't work at all. Few of your assertions about handling the countermeasures have been or ever will be tested in the real world.

Much of your objection is "it would make the payload heavier". So what? They'll build bigger missiles or lighter warheads. You assume a static situation; that's not the case. Our potential adversaries will adapt as fast as we can sink money into this giant black hole.

This really is nothing more than the latest in a long line of US technological bluffs that included the SAGE air defense network and the original SDI. Each has been extremely expensive and would never work in actual combat conditions, but just by letting the world see us spending so much money, we hope that they're bamboozled into thinking that we're building something that actually does something.

This is much easier to do if the attacker knows that a significant portion of the attacking missiles won't make it to their targets, and that he cannot prevent a certain, devastating retaliation.

We were talking about China and other small countries here. They're already going to get certain, devastating retaliation if they try to launch any missiles. They already know, as you've admitted, that at least some fraction of the missiles are going to get through. The best way for them to increase that number is to just build more nukes, and that's exactly what's going to happen each time we increase defensive deployments. And we won't even feel any safer, because no matter how much handwaving you do, we can never be really certain that they haven't put effective countermeasures into their missiles.

Re:This is to prevent a hot war with China.

[AJWM]

SDI worked, it defeated the Soviet Union. That was all it was intended to do. For all the risk that nuke wielding terrorist nations, and even China, might pose, that's a tiny percentage of the thousands of nukes that the USSR had ready to go. (Sure, Russia still has plenty of those, but they are far less likely to use them. We're not exactly worried about Britain or France's nukes, either.)

They'll build bigger missiles or lighter warheads. ... The best way for them to increase that number is to just build more nukes,

All those approaches cost money. Lots of it. Nuclear and missile technology is expensive, especially if you want it to work when and only when desired. It also takes time to develop and deploy. Buying time is worth doing, because the rules of the game may suddenly change (as witness the USSR in the fall of 1991).

As for whether it would "really" work if push came to shove, that's irrelevant. As Sun Tzu tells us, defeat occurs in the mind of the enemy. If he believes the defense may work well enough to spoil his offense, he will not launch it. If he doesn't believe that and launches an attack, then even if the defense turns out to be an amazingly 99% effective (nothing is 100%) we have a mess on our hands. (And the enemy is toast.)

Exactly -- I was going to say the same thing, but you beat me to it.

The flip side to having Free software is that you have to be prepared to let some people that you might not exactly like or agree with use your work. On the other hand, people who might not like you very much have to do the same.

The community would really be shooting itself in the foot if they put some sort of clause like that into OSS licenses, because basically it would be throwing away all the millions of dollars of R&D money that government contractors can and do put into software development, and which might trickle down into OSS projects. Plus, there are a lot of companies out there that you wouldn't think would be affected, that might shy away from OSS after a restriction like that was added, just because they don't want to limit their future business. IBM, for instance, probably wouldn't want to write itself out of the defense sector because some hippies thought it would be cool to ban military uses of Linux, and they're one of the biggest contributors. The NSA, if I remember correctly, has a secure distribution of Linux that's provided some useful things back to the community, and you'd be throwing that away as well. With the exception of RedHat and a few other Linux-only shops, a lot of money comes from companies that sill have proprietary OS options sitting around. If they start to feel that Linux is a hindrance instead of an advantage, there's nothing stopping them from going back and pulling the plug on their OSS ventures.

Overall, it's a foolish and dangerous idea to consider such limitations in licensing, and I think it's important that we put that idea down quickly before it gains any mindshare. It would quite literally be the end of the corporate deep-pocket support of Linux that we've enjoyed until today.

There is a message above about ties to what you describe as "a mechanism of legalized killing." Certain contributors such as IBM, etc., may not want to play in the OSS arena if segments start to get excluded.

The military is not a true "thing" in and of itself. Our military / armed forces are a set of people with given goals and directions. While you may disagree with some of the political goals executed as a whole, let's remember that a military unit is composed of specific individuals.

Legalized killing? Again, a matter of perspective. There are, however, actual people involved at all levels that may contribute to the OSS effort in general.

Sure, it means that various "L33T h4x0R" script kiddies can download software without paying for it, but maybe that really doesn't make up for the fact that any military (not just ones from countries that you like) can incorporate software into systems designed to kill people. If you were a GPL software author, you could discover that code you wrote was used as part of a weapon system used to kill innocent people -- maybe even your own wife, children, and parents. (Yes, I know that MD is defensive, but OSS could just as easily be used for offensive weapons.)

#1 : All military contractors and personnel would suddenly stop contributing to any OSS efforts.

So what? If someone is a conscientious objector to war, why shouldn't he prohibit military use of his code? Is supporting OSS supposed to be a more important to him than his beliefs about killing human beings?

Fundamentalist Christians could be placing a "free for non-gay use" clause in their releases.

Oh no! The gay community would be denied access to thousands of amateurish Bible study programs! What a tragedy that would be.

Welcome to Hunt the Terrorist

The Terrorist lives in a cave of 20 rooms. Each room has 3 tunnels
leading to other rooms. (Look at a dodecahedron to see how this works
- if you don't know what a dodecahedron is, ask someone.)

Hazards:

explosive mines - Two rooms have explosive mines in them. If you go
there, you are blown up by the mine (and lose!)

Super Copters - Two other rooms have super Copters. If you go there, a Copter
grabs you and takes you to some other room at random. (Which might be
troublesome.)

Terrorist:

The Terrorist is not bothered by the hazards (he has sucker feet and is
too big for a Copter to lift.) Usually he is asleep. Two things wake
him up: your entering his room or your shooting an missile.

If the Terrorist wakes, he sometimes runs to the next room. If you
happen to be in the same room with him, you lose.

You:

Each turn you may move or shoot a crooked missile.

Move: You can move one room (through one tunnel.)

missile: You have 5 missiles. You lose when you run out. Each missile can
be shot from 1 to 5 rooms away. You aim by telling the computer the
room #'s you want the missile to go to. If the missile can't go that way,
it moves at random to the next room.

If the missile hits the Terrorist, you win. If the missile hits you, you
lose.

Warnings:

When you are one room away from Terrorist or hazard.

The computer says:

Terrorist - I smell a Terrorist
Copter - Copters Nearby
mine - I feel a draft

I have tested it for you !

THAAD is theater defense, not strategic defense.

Sorry, I had to say that, I _love_ French Fries, French Toast, and lots of other French foods. And hey, French kissing! Whats not to like? All things French in general. Except Quebec of course. But then, Quebec is not really French now, is it? They are really Canadian. And what is that whole thing with "Canadian Bacon"? That's not really bacon. I mean, it is tasty and all. Great in Eggs Benedict. Yum. But Bacon it is not. And as far as Quebec, French it is not. So what is it about Canada about all that fakery? Except the beer of course. I like that Canadian Beer. American beer is just so, so, cheesy. I like Toronto a lot too. Nice city, but then, it is not really Canadian! Not like Ottawa. Now there is a Canadian City for you. Wonderful people, crap weather. Even Canadians complain about the weather up there. Given how harsh it is, it is amazing how nice they are up there. Not like Quebec City (or Montreal...) at all. No sir. Folk are nice in Toronto too. They are, and it is a close drive from here. Watch the speed limits though, the goofy signs are all in Kilometers per hour, not miles. So when it say 100 it means, you know, 100 not _100_. The nice officer cut me some slack though, and issued a warning. I guess he figured I really was just a thick skulled American. It was an old car too. Only one set of marks on the speedometer, so I pointed the needle at the only 100 there. He was nice, so I graciously offered him one of the nice Canadian beers I had behind the seat, and he graciously accepted. Luckily, he had an opener, because they weren't twist tops. So actually the stop benefitted us both. Nothing like cruising up the QEW to Toronto with one hand on the wheel and the other holding a cold Molson Export.

Re:the right tool for the job?

[Anonymous Coward]

> Linux isn't really a realtime OS.

You are wrong. Linux is a hard realtime OS (and you can get soft realtime without making a big effort) when you have the right hardware and the right scheduler. This Linux OS has independent timers and a special scheduling system, which makes it run realtime with granularity of microseconds in the simulation. Now you will ask how I know that... Ill tell ya, I work with this product, as a control engineer, and help desk for this product.

The difference of this version Lockheed purchased is that its not an Operating System, but a full HIL/MIL (hardware in the loop, man in the loop) system, which means the software, the computer, special acquisition I/O cards, the special timer system AND a special set of realtime debugging tools that are the hottest thing available. I could try to explain you what these tools are all about, but i) people would tell Im doin marketing bla bla bla and ii) I doubt you understand industrial simulation, so I must assume you are some student repeating like a parrot that QNX this, vxworks that. But just to prove Im not lying, these tools are able to hot patch a running code without stopping the process (when you have the source available, in C, C++, Fortran and ADA), kernel intrumentation, graphical view from the scheduler taks, execution time of process and syscall, cpu isolation to run a dedicated simulation in a certain cpu, you can monitor critcal vars and setpoints in a GUI, so you can run the simulation and check they are never out of the sweetspot, running distributed simulations in high speed deterministical networks, etc, etc.

But goin back to the topic, these debugging tools are amazing and a great add-on to the package. Im not surprised of the choice, the product is very good. And its something the RTLinux (from FSM Labs) and Wind River versions (of Linux - ya, they are doing linux too, or even its VxWorks doesnt have).

The reason Linux is not so popular is that these guys are really really traditional people, and they dont change very often their tools, its hard to break the stablishment. In the other hand, some simulations users loves using Linux in their simulation systems. Others are using other solutions for years, and dont feel the need of changing them, no matter how painful it is to run old/legacy applications.

So just to finish my point. This is a full simulation system that can do the job even better than other proprietary solutions, and with a better cost-benefit. Its not "clever trick". The people who make this product are not newbies (they are playing this games for decades, check their history), neither their users. They didnt pick up this solution because they are cheap, or they look beautiful, or they like tux. They picked because its the finest one available.

>Something that was...well, designed to do RT, and designed so you can easily take >out all the stuff you're not using (think less room for bugs).

You can do that with Linux OS. FSM Labs has versions that can boot in 300 miliseconds to full operational status and as small as some kbytes. If you use google a little, you will find some harcore realtime systems with linux

[Voltageaav]

In 1998 the Commission to assess the ballistic missile threat to the United States gave this report. There is evidence that North Korea is working hard on the Taepo Dong 2 (TD-2) ballistic missile. The status of the system's development cannot be determined precisely. Nevertheless, the ballistic missile test infrastructure in North Korea is well developed. Once the system is assessed to be ready, a test flight could be conducted within six months of a decision to do so. If North Korea judged the test to be a success, the TD-2 could be deployed rapidly. It is unlikely the U.S. would know of such a decision much before the missile was launched. This missile could reach major cities and military bases in Alaska and the smaller, westernmost islands in the Hawaiian chain. Light-weight variations of the TD-2 could fly as far as 10,000 km, placing at risk western U.S. territory in an arc extending northwest from Phoenix, Arizona, to Madison, Wisconsin. These variants of the TD-2 would require additional time to develop and would likely require an additional flight test. I'd also like to point out that was 7 years ago. http://www.fas.org/irp/threat/missile/rumsfeld/exe csum.htm

Re:the right tool for the job?

[Vo0k]

but it wasn't built for RT from the ground up.

And that's why it won here.
This distro IS true Realtime OS, with kernel modified to work in realtime. In this it's equal with all the other available RTOSes, or even a bit below, because the support for realtime operation is young and not fully-featured. But while other RTOSes focused on adding more features, making it more stable and such, while neglecting actual efficiency, plain vanilla linux was developed to be a speed monster, with all that extra schedulers, optimizations, support for custom architectures, SMP and all the stuff that just made it a very FAST OS. Then the RealTime extension was added.

Make no mistake, Realtime doesn't mean fast. On normal systems, no matter how much CPU power, you can't guarantee some thread won't be stalled for longer than X miliseconds. On RTOS, given certain hardware speed and certain software load you can -guarantee- some threads will be given time within some fixed time. Often longer than they usually get on non-RTOS, but never longer than certain X miliseconds.
Now thing is, how much can the X be, and what does it depend on? Well, certainly on amount of $$$ you put in the hardware, more CPU power = more spare CPU power that can be given sooner. So theoretically: Give enough CPU power, have arbitrarily short guaranted response time, down to time of one loop over the kernel procedures. In reality: You have just as much hardware, and the kernel of the RTOS eats up most of the resources, and due to all the failsafe checks, runs quite slowly in fact. True, at a constant safe pace that allows for granted 20 frames per second of input sensors analysis. But if you want 30, sorry, it starts crubmling, CPU overloaded, failsafes launched, frames lost. As long as you tell it to grab 20 frames a second, it won't fail, ever, no matter what though (as opposed to non-RTOS, which may lose a few frames just because it needed to swap out some memory or run a cron job in the background).
All RTOSes do this. x MIPS, y RAM, m miliseconds for response, n miliseconds when the thread must finish or it will be forced to finish. Plus costs, reliablity and all the standard issues with any generic OS.

Now, given certain speed of hardware, what speed can you guarantee? Depends on the OS, and the faster the OS, the better the speed. And while Linux is really very fast, others aren't so. Writing a system that GUARANTEES 50 fps instead of 20 fps is damn hard. But writing a normal system that does 90fps on the average, without lowest speed guarantee? Well, possible, not so hard. Just keep it optimal. Then throw in the extra bits that make it a RTOS, and you notice that even after the RTOS overhead it never gets below 70fps. Check most pessimistic scenarios and you see it will never drop below 50fps.

THAAD

[Karrde712]

First point. THAAD is actually "Terminal High Altitude Area Defense" and is being developed concurrently between Lockheed Martin and Raytheon.

I worked on the THAAD project for Raytheon from 1999-2000. Here is the unclassified description of how it functions:

Upon radar detection of an incoming missile (such as a SCUD) the THAAD missile is launched against it. Unlike earlier technologies for missile defense (such as the PATRIOT*), the THAAD missile does not contain any explosive warhead, instead using the available space and weight for a more sophisticated guidance system. The THAAD warhead contains an active guidance system that will seek the incoming missile and collide with it, destroying the incoming missile with its own warhead.

Earlier technologies relied on a wide-area warhead that would be detonated once the missile was within a certain diameter about the target, relying on the concussion wave and shrapnel to destroy the missile. This was unsatisfactory as in some circumstances the missile would destroy only the target's propulsion system and allow the undamaged warhead to fall to the ground, resulting in collateral damage.

*The PATRIOT missile was not designed as an anti-missile weapon, it was in fact designed as an anti-aircraft weapon, but was retasked during Operation: Desert Storm to shoot down SCUD missiles. It was considered very impressive that it worked at all, considering it was designed for use against much slower-moving targets.

This by itself doesn't mean anything though. Remember that the GPL doesn't require you to make your code available online to just anyone, it just says that you have to distribute it along with the software. So it could be something as simple as a /src directory on systems they sell, or on the CDs or however they distribute it.

They can't prohibit you from buying the product and redistributing the source code, but it doesn't mean they have to go out of their way to make it particularly easy for you to do so. The only real way to tell if they're breaking the license would be for somebody to buy RedHawk Linux in whatever form is closest to a "retail box" and see if it comes with source, or a written offer to provide it. I believe those are the requirements of the GPL.

The alternative: Mutual assured destruction

[s20451]

For those who oppose missile defence, I ask: The only other thing protecting you from nuclear attack is the fact that the United States is willing to commit an act of genocide to avenge your death. Does that make you sleep better at night? Especially since this does not protect you against mistakes, malfunctions, or insanity.

Re:The alternative: Mutual assured destruction

[hey!]

For those who oppose missile defence, I ask: The only other thing protecting you from nuclear attack is the fact that the United States is willing to commit an act of genocide to avenge your death. Does that make you sleep better at night?

Well, it's a very nice sounding argument, but very poorly thought out in my opinion. The question then is not do I sleep soundly when the only thing that keeps nuclear armageddon in check is mutually assured destruction? The question is am I justified in sleeping more soundly after we deloy a missile defense system? I think it is all to common to examine only one side of the coin -- the intended outcome -- and not the other.

The way the missile defense would work in an idealized world is that (1) it would operate well enough to significantly reduce damage, (2) enemies would not adjust their tactics to avoid the systems strengths and target its weaknesses and (3) our leaders would not place undue faith in the system's ability to protect us from the consequences of their actions.

Now, suppose that another hypothetical world that (1) the system while somewhat effective nonetheless lets enough through to do severe damage (2) enemies adjust their technologyt o reduce the system's effectiveness or choose other delivery systems such as cruise missiles launched from off our coasts or shipping container bombs and (3) our leaders act as if the system is a complete and flawless defense despite the prior two points.

Now, should I sleep better at night in that hypothetical world?

Especially since this does not protect you against mistakes, malfunctions, or insanity.

I think this is a reasonable target for technological counter measures, provided we don't delude ourselves, which we're all to prone to do.

Re:The alternative: Mutual assured destruction

[sickofthisshit]

Strawman argument. Missile defense is not protecting us against any of those things in a realistic sense.

Missile defense has not proved anything near the ability to prevent an attack by multiple advanced missiles, particularly those which would use even relatively simple anti-simulation decoy techniques.

For the newbies to missile defense, "decoys" are typically large mylar balloons which inflate in space to create radar targets as large or larger than a warhead. They are extremely cheap and light, so anybody able to make an ICBM can afford to put many decoys in their missiles. "Anti-simulation" means you put the warhead in a balloon, or in some other way make it look very similar to the cheap, plentiful decoys.

Now your putative missile defense system has to somehow deal with dozens of things that all look like cheap decoys, but only a handful are actually warheads.

The missile defense folks will hem and haw about how their system is not meant to deal with a sophisticated enemy, which is code for "we think North Korea can't really make fancy warheads that maneuver like we think Soviet warheads can" but ignoring the fact that mylar balloons are not sophisticated. Or that it is only meant to handle single isolated launches, like might occur by "accident." Or they'll say they are only deploying the system to provide the opportunity for more realistic testing. Or that they really need a launch-phase system (before the decoys get a chance to deploy), which needs to be very near the launch site, so you need to post sailors or soldiers very near North Korea (because you can't get close enough to China or Russia's launch sites without invading their territory) whenever you think a launch is probable, and keep them ready enough to respond in minutes.

As opposed to sitting around in Alaska waiting for a single warhead, with at most a few decoys, to come sailing up from North Korea, and hoping that North Korean missile designers never heard of mylar balloons. Then you get to see if the *many* billions of dollars we've spent on this system pay off or not.

Re:The alternative: Mutual assured destruction

[s20451]

I agree, I don't think the problem of intercepting the missiles in space will be solved until the kill devices become as cheap and easy to launch as the decoys, which will probably not be for decades.

However, with existing technology it is trivial to distinguish real vehicles from decoys in the upper atmosphere, say 50 km up, because the light decoys will fall behind the heavy warhead. The energies and distances in this phase of flight mean that successful interception would still destroy the warhead without harming anything on the ground. This is the kind of environment that the article is talking about.

And, sure, missile defence has issues -- it is a fundamentally difficult problem. But I don't see an alternative. I find MAD extremely distasteful, and there have been enough near misses to discredit it as a permanent solution. Disarmament is probably hopeless: the past 15 years have seen unprecedented peace among nuclear-armed nations, yet proliferation is getting worse.

The problems take time and effort to solve, which is why I advocate missile defence research. I do agree that many current implementations suck, but this does not imply that the idea is impossible.

Re:The alternative: Mutual assured destruction

[s20451]

I agree that point (3) is a problem. Points (1) and (2) are technological issues that can be solved with time.

I think the "cruise missiles and container bombs" argument makes no sense, because these two delivery systems do not have the same potential as ICBMs. A cruise missile is basically a jet aircraft, and we already know how to shoot those down. They also take a relatively long time (i.e., hours) to arrive at their target, giving plenty of warning. As for container bombs, you could use them to attack a city, but you could never get one close enough to a hardened military installation to do significant damage. It would be an effective tool for terrorists, but totally worthless as a military strike. And it would be almost impossible to co-ordinate more than a few simultaneous container-bomb attacks.

By contrast, ICBMs can be used to attack any target in the world, take around 45 minutes from launch to impact, can be used in co-ordinated attacks of unlimited size, and cannot be stopped with existing technology.

The promise of missile defence is to make massive nuclear attack obsolete as a weapon of war. I think that is a worthwhile goal.

Re:The alternative: Mutual assured destruction

[hey!]

The promise of missile defence is to make massive nuclear attack obsolete as a weapon of war. I think that is a worthwhile goal.

Yes, I agree it is a worthwhile goal. However I don't think we'll see it my lifetime.

I think the "cruise missiles and container bombs" argument makes no sense, because these two delivery systems do not have the same potential as ICBMs.

Remember, most of the US lives within twenty miles or so of the coast. Consider the Katrina situation. Imagine how much worse a small Hiroshima sized bomb would have been. Consider the following list of cities:

Miami
Tampa
New Orleans
Houston
San Diego
Los Angeles
San Francisco
Boston
New York
Philadelphia
Baltimore
Washington DC

All of these cities are ports that are vulnerable to a container bomb, or they are close enough that an incoming freighter could launch a cruise missile attack with only a few minutes notice. Although missiles could be shot down, it is unlikely. Launched from within fifty miles or so of their target, the missiles are likely to arrive in less than ten minutes, and may not even be detectable. It is also possible that they could be delivered in automated aircraft which are indistinguishable from civilian aviation.

I'm assuming the midwest would be safe because it would not be risky to deliver a bomb via the St. Lawrence Seaway. Other cities with international airports might be vulnerable if control is not effective at the departing port.

Hit one of the cities on this list and you've dealth the country blow far more severe than 9/11 or Katrina. Hit two or more and the blow might be critical. Hit three well chosen cities from this list and it's very possible you won't have to worry about hitting hardened military targets -- American society might well collapse.

By contrast, ICBMs can be used to attack any target in the world, take around 45 minutes from launch to impact, can be used in co-ordinated attacks of unlimited size, and cannot be stopped with existing technology.

A hawk may dive at 200MPH from high above, but an owl dropping from ten feet above at 35MPH is a more fearsome predator. The reason is stealth. The prey doesn't have much time to react to the sound of the diving hawk, but the owl kills before it is perceived at all.

And the kind of attack scale ICBMS are capable of are overkill. The only argument for this capacity because they target hardened military installations. A mere handful of cities is all that is needed to cripple this country. Certainly it would not be difficult to attack six or seven major cities within the course of a few minutes using low tech delivery systems under the guise of normal international trade.

What I'm saying is that once the genie is out of the bottle, there is no technical fix.

The cornerstones of homeland defense really ought to be international cooperation on law enforcement, customs and nuclear non-proliferation. I realize that as rugged individualists, this is distasteful.

Re:The alternative: Mutual assured destruction

[sickofthisshit]

"Upper atmosphere" is terminal phase, meaning your interceptors need to act even faster, and must be located even nearer the target.

In any case, you have to look at the cost-effectiveness of any scheme against other competing schemes and threats. Ballistic missile threats from organized militaries seem much less important to me than other delivery mechanisms potentially used by terrorists, included state-sponsored ones. The countermeasures against those include non-proliferation, securing of nuclear materials, more intelligence gathering, and effective action against terrorist groups. All of which are much cheaper than massive hardware development.

Yes, research is useful. But research down avenues that have poor performance even if they are successful is wasteful compared to investing in approaches which have more chance of success.

Spending billions so that we can actually pour concrete in Alaska to base a non-proven system doesn't really count as "research" either.

Re:The alternative: Mutual assured destruction

Does that make you sleep better at night? Especially since this does not protect you against mistakes, malfunctions, or insanity.

That's an idiotic argument. Nuclear weapons aren't the only deterrents; you've also got the massive conventional arsenal of the United States military- tomahawks, laser-guided bombs, fuel-air explosives, you name it. Plus, if anyone ordered a pre-emptive attack, they would also have to deal with the possibility of allied nations like Britain declaring war on them. Finally, you've got the economic argument. Most nations benefit from trade with the United States. China, for instance, probably isn't going to nuke us as long as we continue to buy billions of dollars of their imports.

Re:The alternative: Mutual assured destruction

[sickofthisshit]

Massive nuclear attack *is* obsolete, and can't be prevented with practical missile defenses anyway. Which is why NMD advocates talk about defending against *small* ballistic missile attacks.

ICBMs are expensive and leave an obvious return address for retaliation. A *small* attack is not likely to be used against hardened military targets, but against soft targets, and typically civilian ones. Container bombs are cheaper and more effective ways for an adversary to accomplish terrorist goals, and actually *launching* a small attack means the deterrent aspect has already failed.

North Korea does not have long-range missiles and nukes to actually use them except in some last-gasp scenario. They have them to deter U.S. military action by adding risk and uncertainty to U.S. plans. Spending many bilions of dollars for an ineffective defense which will likely never be used is a total crock, especially when all military plans against North Korea suck anyhow.

Re:The alternative: Mutual assured destruction

[s20451]

Your argument is based on the premise that if a few American cities were attacked by nuclear weapons, civilization would collapse and the military would be neutralized. I think this is unlikely. Experience from World War 2 has shown that nations can absorb horrific damage without collapsing, and still retain most of their military strength. Also, if you look here (using 0.02 megatons for a Hiroshima-sized weapon) and compare it to this, you will find that the damage inflicted by Katrina is about the same, or greater.

Container bombs can also be stopped by intelligence. If the government is tipped off to expect a container bomb, the navy can be used to hold and inspect all ships to find the weapon(s). There will be some economic stress, but the attack will have been thwarted.

What I'm saying is that a government that is serious about conducting a nuclear war will use ICBMs in large numbers. For a state (even in the guise of state terrorism) to use a container bomb against a handful of US cities, leaving the military intact, would be suicidal. This is why missile defence is important.

Re:The alternative: Mutual assured destruction

[s20451]

I never specified that the act of genocide did not include conventional weapons. So you are confirming my argument.

Also, are you saying that because the US is friendly with nuclear-armed nations today, that it will be friendly with them forever?

Re:The alternative: Mutual assured destruction

[hey!]

. Experience from World War 2 has shown that nations can absorb horrific damage without collapsing, and still retain most of their military strength.

It's a good point. However I think there are key distinctions to be made.

(1) The economies of these countries were on a war time footing. Everything that was destroyed that was essential to the war effort had to be replaced. Therefore there was a clear productive focus; war stimulates the economy. If the enemy blows up bridges, you already have programs to recycle the scrap into more bridges in place. If the enemy disrupts your communiccations, you have alternate channels. If the enemy destroys some of your distribution systems, you have rationing in place. In the case I'm positing we would not be on a war footing at all, and none of these adaptations would be in place, so the chaos in each city would be New Orleans many times over, multiplied by the number of cities.

(2) The damage to the infrastructure in past wars was over months or even years, giving the government and industry time to adapt. I'm talking about doing as much as was done to Germany in WW2 and in some ways possibly more, but happening in the space of a few hours.

(3) Our enemy may not be identifiable or provide us with a clear target to focus on. There is no enemy to drive into the sea, no Hun fatherland to conquer. We might not even know who hit us. We may have no idea whether we continue to be vulnerable or not.

(4) Our economy is more dependent on agility and communication than the mid 20th century economy. We don't do much manufacturing and we do a lot of communication. We're more highly dependent on international trade. When we do manufacture things we're more likely to eschew inventories and vertical integration in favor of elaborate coordination with suppliers. All of which says that disruption of supplies and communications are many times more damaging to us.

I'm not saying it is impossible for civilization to survive a massive sneak nuclear attack. But I don't think anything says our civilization has to be immortal.

Re:The alternative: Mutual assured destruction

[sd_diamond]

I agree that point (3) is a problem. Points (1) and (2) are technological issues that can be solved with time.

(1) perhaps, but not (2). Adversaries will always adjust tactics to route around defensive systems. The very best that anyone can hope to accomplish with a missile defense system is to make ICBMs obsolete as a delivery method for nuclear weapons. In which case, someone wishing to launch a nuclear attack will just find a better way to deliver the warheads -- whether with earth-hugging stealth cruise missiles, or by smuggling them across the border on ships, trucks, and airplanes.

If anything, 9/11 proved that big, fancy, expensive SDI systems are even more pointless today than they were in the '80s.

Re:The alternative: Mutual assured destruction

[Anonymous Coward]

"Now your putative missile defense system has to somehow deal with dozens of things that all look like cheap decoys, but only a handful are actually warheads."

Terminal guidance is not radar based, it used an extremely slick broad spectrum IR imaging system that has excellent discrimination capabilities. It would be impervious to just about any decoy cheaper than just putting another functioning warhead on the missile. Versions of the same guidance package are used in other deployed weapon systems; most of the problems with THAAD and similar revolve around the rocket platform, which is a new design.

It is worth pointing out that the discrimination capabilities of modern US sensor systems frequently outperform human abilities with the same data. It is pretty standard for advanced discrimation systems to be able to determine the make, model, and variant of the targets they detect. The idea that IR guidance is "heat seeking" mischaracterizes what is essentially a very intelligent image processing system that just happens to use broad swaths of the infrared spectrum when compositing its images and constructing its model of the target.

Re:The alternative: Mutual assured destruction

[bemenaker]

I totally agree with what you said here. N. Korea's search for nukes is strictly a bargaining tool, and a fail safe. If you take us out, we will make it very painful to you. N. Korea would absolutely NEVER fire a nuke at the US. Why would they, the standard response to that is for us to nuke them flat, and we can, and we will. This whole missle defense shield is a way that the war hawks in DC want to try to tip the bargaining scales back in the US's favor.

For as horrible as Bush is in global politics, this one almost looks like a smart move, until you realize that the whole plan is a smoke screen. Right now, 3 ICBM's makes the system worthless. Actually, two would, the system is statistically inaccurrate enough that one of two would get through.

Re:The alternative: Mutual assured destruction

[sickofthisshit]

Yeah, I was very imprecise in my description. I should have said "re-entry vehicles" instead of warheads too.

But antisimulation works in the IR too, with a little heater, or playing games with emissivities. North Korea has all the time in the world to think up tricks, and your IR sensing solution has to cover the whole range of possible tricks. We can't really know how North Korea's decoys are going to differ from antisimulated warheads. Brighter? Dimmer? All the precision in the world doesn't help when you don't even know the right sign. Keep in mind the decoys and targets in the tests so far have been deliberately made to look different.

All these solutions work great when you know what is being thrown at you. When your first time looking at the North Korean re-entry vehicles and decoys is on game day, then my confidence in any solution gets a lot shakier.

Re:The alternative: Mutual assured destruction

[r00t]

This "can't be prevented with practical missile defenses anyway" idea is either wrong or missing the point.

Suppose that, in any given year, international relations (diplomacy, non-proliferation treaty, trade, cultural export) is 99% effective. Suppose that an anti-ICBM system is only 50% effective. Well, the defence is 99.5% effective if you have both!

This isn't all that different from protecting a Windows computer network from attack. You don't rely on the firewall alone. You don't rely on Windows update alone. You don't rely on anit-virus software alone. No, you use all the tools you can come up with, even though none of them are perfect.

Re:The alternative: Mutual assured destruction

I agree that "the cornerstones of homeland defense really ought to be international cooperation on law enforcement, customs and nuclear non-proliferation", and in no way find it distasteful.

This does not mean that technical solutions should be ignored.

A technical solution that fails half the time is a technical solution that succeeds half of the time. If you are a pessimist, it is easier to notice the potential for failure. Hey, the glass is half full!

Actually, it's better than that. If a technical solution would succeed 50% of the time, it will also discourage attack. So the effective success rate is much higher that the success rate seen when we assume that the attack will be made.

Re:The alternative: Mutual assured destruction

Are you sure? In Europe during the Cold War, senior NATO officers operated on the policy of "use it or lose it" -- if their position was about to be overrun, and their nukes captured, they were expected to launch. Surely this logic would also appeal to North Korean officers.

Re:The alternative: Mutual assured destruction

Diplomacy is practically free. Missile defense is fucking EXPENSIVE, you dimwit.

Plus, your 50% is highly optimistic. Pardon me if I don't feel it is a good idea to spend hundreds of billions of dollars for that extra 0.5% in protection, diverting money from dealing with REAL threats.

NOBODY believes a *massive* (did you miss that word?) attack can be prevented by a practical ABM system. That's the whole reason people abandoned the Star Wars model and came back with a scaled down system to protect against a *limited* attack.

Windows computer viruses are a present REALITY. ICBM attacks are a worst-case POSSIBILITY. The Soviet Union with thousands of ICBMs never attacked, despite our lack of ABM defenses. Funny, huh?

Re:The alternative: Mutual assured destruction

[sickofthisshit]

You are positing a U.S. offensive against North Korea, then. The scenario was "the U.S. is just minding its business when North Korea decides to launch a nuke." *I* specifically excluded "last-gasp" anyway.

Even if they did launch during a U.S offensive, it would almost certainly be against U.S. bases in Japan, just as the U.S. would have used them against Warsaw Pact forces and the logistic chain behind them. Hitting U.S. territory would be absolutely pointless, and do nothing. Hitting military forces while they are attacking is completely within the rules of war, and might have a slight chance of preventing utter defeat.

Re:The alternative: Mutual assured destruction

[r00t]

Diplomacy isn't even remotely cheap. Check out our "foreign aid" budget. That's only part of the cost of diplomacy.

Missile defence isn't quite expensive as it looks, at least if you consider the whole economy. It's like sending people to the Moon. All sorts of high-tech inventions happen.

I believe a *massive* attack can be prevented by a practical ABM system because:

• the attack might not happen if the ABM system is deployed
• the attack might be moderate once the ABM system takes out some of the warheads

Quit living in a dream world. Nuclear war will happen again, eventually. Our defences will fail some of the time. Would you like the average frequency of failure to be once every 80 years or once every 400 years? Would you like small failures, with a few cities winding up like New Orleans, or big failures with every part of the country looking like that?

To not even deal with the threat posed by a small attack from one region of the globe, just the first part of a system, and not passing basic tests.

They are extremely cheap and light, so anybody able to make an ICBM can afford to put many decoys in their missiles. "Anti-simulation" means you put the warhead in a balloon, or in some other way make it look very similar to the cheap, plentiful decoys.

There are also other things you can use to make seeing where the actual warheads are. e.g. strips of foil. Even lumps of concrete designed to survive reentry. The most difficult part of making a working ICBM is the rocket. Even countries with lots of experience in handling rockets cannot get them to function with the kind of reliability typical of other vehicles.

Or that they really need a launch-phase system (before the decoys get a chance to deploy), which needs to be very near the launch site, so you need to post sailors or soldiers very near North Korea (because you can't get close enough to China or Russia's launch sites without invading their territory) whenever you think a launch is probable, and keep them ready enough to respond in minutes.

Most likely this would equate to keeping a fleet of ships near to somewhere which might be a threat. Capable not only of shooting down an ICBM, but also able to defend itself against attack. Since any country capable of launching an ICBM undoubtedly also has the ability to carry out much shorter range attacks against land or sea.
An ABM system is also utterly useless against the threat of someone smuggling a nuclear weapon into your country and delivering it using a truck. Which is considerably cheaper, much more stealty and has more chance of actually getting to the target than sticking it atop a large quantity of explosive.

I think the "cruise missiles and container bombs" argument makes no sense, because these two delivery systems do not have the same potential as ICBMs. A cruise missile is basically a jet aircraft, and we already know how to shoot those down.

The US failed to do this with some big airliners are few years back. If in someone were to use an aircraft as an improvised nuclear cruise missile they could use a light aircraft. Rather harder to spot and a small jet typically has much better performance than an airliner.

As for container bombs, you could use them to attack a city, but you could never get one close enough to a hardened military installation to do significant damage. It would be an effective tool for terrorists, but totally worthless as a military strike. And it would be almost impossible to co-ordinate more than a few simultaneous container-bomb attacks.

Even a few such attacks would be serious. Even many potential military targets are fairly soft. Whilst fences and guardposts may prevent people and vehicles entering they arn't going to stop a bomb going off just outside.

By contrast, ICBMs can be used to attack any target in the world, take around 45 minutes from launch to impact,

It has the rather big drawback of giving 45 minutes warning, not very useful if the intent is to do something like killing lots of political leaders at once.

can be used in co-ordinated attacks of unlimited size

Assuming to have large number of rockets to hand.

Re:The alternative: Mutual assured destruction

[mpe]

Launched from within fifty miles or so of their target, the missiles are likely to arrive in less than ten minutes, and may not even be detectable. It is also possible that they could be delivered in automated aircraft which are indistinguishable from civilian aviation.

Even actually be a civilian airliner. Finding a suicide pilot is unlikely to be too much of a problem for any military or paramilitary... September the 11th showed that a scheduled airliner can be way off course before alarm bells start ringing. Anyone capable of planning an attack using their own aircraft can probably file a flight plan.

I'm assuming the midwest would be safe because it would not be risky to deliver a bomb via the St. Lawrence Seaway.

Probably not a good assumption. If you can get a bomb into a container port it probably isn't that much harder to get the container onto a truck. Where it can literally go anywhere there is a road.

Stability & Speed a Key in Defense Systems

[trygstad]

People can debate the morality of this all day without really accomplishing anything, but as someone who operated technically sophisticated weapons systems, I can speak from experience as to the value of having an OS that is rock-stable and fast. As a long-time anti-submarine warfare helicopter pilot, the last thing I want ever want to see on my center console screen would be a blue screen of death, because in a shooting war, the "death" part might be far more literal than figurative. The morality of the use of technologies for war is a debate for politicians and academics; for those who are at the cutting edge of the spear--who are all volunteers and are there defending your right to even have this debate--the only thing that really matters about a technology is does it work now, and will it work without fail every time it is needed. Personally I'd go with Linux with a great deal of confidence. And if the political will of a nation is going to ask some citizens to lay their lives on the line to protect the bulk of the people, don't those folks on the cutting edge deserve to have the very best tools to do their job?

Way Back When

[jmichaelg]

I worked on an air defense system back in the 70's. It was built for the King of Morroco so he could show off to the other despots in North Africa. It wasn't as if Morocco was seriously threatened by anyone but I guess that having been overrun by the Germans, French and the occasional American task force rescuing a Greek who claimed to be an American, the king was a little concerned. The system consisted of two radars parked on a couple of mountaintops talking to a single cpu which updated a couple of consoles and huge wall screen. Whereas the consoles got the standard cryptic designators for each plane, the wall screen got elaborate detailed descriptions since they were for the king to read. The cpu was the fastest cpu of the time, a 16 mhz behemoth that filled a room.

The guy I reported to was one of the smartest people I've ever met and fortunately for the project, he was responsible for the software. He'd come into our offices (the only people that worked in cubicles back then were HP employees) and see how we were doing. He'd frequently find us waiting on a compile as the machine was hard pressed to have 30 or so developers using a single computer to compile with. It began to bother him quite a bit because he'd read the design spec which called for the system to handle a couple of 1000 radar returns each minute. As he was technically capable, he sat down one day and wrote a radar simulator that fed radar packets to a "processor." All the processor did was count the number of packets it received and all the radar simulator did was send empty packets. Not a very complicated piece of software but it was enough to show the hardware wasn't going to meet the spec. It couldn't do that simple task, let alone process the packets, draw positions on the controller screens etc.

He wrote a memo and sent it up the chain. A week passed and no response so he wrote another memo saying the same thing but he changed the memo title. The new title was "I know you're out there - I can hear you breathing." That got his bosses moving and the problem was addressed.

[Anonymous Coward]

Because that's the real question, here.

Actually, yes

[Anonymous Coward]

Well, first to answer your question directly ...

There is no doubt that a missile delivered point-blank right onto your head is distributing the binary code in its guidance system to you. Indeed, it has committed an unambiguously intentional act of delivery to its specified target, which is you. The only possible counter is that the guidance system developed a fault and distributed the code to you in error.

In practice however, the problem of not being alive to claim your rightful sources is rather severe.

And to add to the difficulties, this might have to be a class action, because detonation a mile up can render it difficult to pinpoint the actual point of delivery and hence the single target of distribution.

Secondly though ... RedHawk Linux is used for systems testing, not end delivery. :-)

I'm not surprized at all

[ChrisA90278]

I used one of the "real-time modified" linux kernels in my work too. I can see why LM selected it. For those who don't understand "real time" is does not mean "runs fast" it means that if I need a task to run once every 100 miliseconds it does just that. If you are doing something like controling a radar transmitter you need _exact_ timming. For jobs like running a web browser a real-time OS may seem unresponsive and "not smooth" They will likely need access to the kernel source code if they are fielding a military system. These systems have long (25 years plus) lifetimes and you need the ability to repair the OS 20 years from now. I used a real time Linux inside an astronomical CCD camera to generate the waveforms that shift the charges acros the rows and out to the amps and digitiziers. the camera moved relative to the target and the charge was shifted in sync with the moving image. Linuix was great. The hard real time stuff could be done with interrupts disabled inside a kernel level driver and the data was written to disk by a user land process. Standard tols and debugers could be used to develope the camera controller. I'm not surprized at all that LM went this way. But the "Linux" they are using is NOT the "linux" you see when you get Ret Hat or Debian.

Re:Hitch your wagon to a star (OCLI)

In 1985 Perkin-Elmer spun off thier computer division and renamed it to Concurrent Computer Corporation.

According to Wikipedia:

The commission blamed the failings primarily on Perkin-Elmer. Relations between NASA and the optics company had been severely strained during the telescope construction due to frequent schedule slippage and cost overruns. NASA found that Perkin-Elmer had not regarded the telescope mirror as a crucial part of their business and were also secure in the knowledge that NASA could not take its business elsewhere once the polishing had begun. While the commission heavily criticised Perkin-Elmer for these managerial failings, NASA was also criticised for not picking up on the quality control shortcomings such as relying totally on test results from a single instrument.

Hardware In the Loop: Been There

[cmholm]

The parent for this thread probably doesn't have any first hand experience with HWIL, but s/he has the basic ideas down. Lemme hit the previous bullets:

Gyroscopic mount: typically, the seeker for the missile (radar, ir, video, whatever) in question is mounted on the gimbals. The rest of the guidance section is in a nearby rack. The reactions of the rest of the missile (fins, motor, body) is simulated in the kinematic codes running on the HWIL simulation computer(s).

Projection screen: a jargon problem. For Radar: an array of radio frequency feed horns are mounted on a wide hemispheric frame about 50 to 100 feet in front of the seeker, which is at the focal point of their output. By varying the frequency, power, and polarity of the energy from each feed horn, one or more targets can be represented. The simulation computer usually takes care of the radar pulse delay to represent range. Simulated changes in target angle are handled by moving the seeker on it's gimbals.

IR projection: a "hot" video display, to my experience using an led array no bigger than a laptop display a few feet in front of the seeker. Video: to my experience, either a large front or rear video projection system, or a tv display a few feet in front of the seeker.

Fins/vectored thrust: in a HWIL system, the aerodynamic controls are usually simulated. The control computer intercepts the commands from the guidance section, and feeds them into the kinematic software for use in the virtual environment.

Movement in 3D space: Why move the seeker at all? Because it's cheaper than moving the display mechanism (whether radar, ir, or video). The seeker is built to withstand intense shock and vibration, small, and usually weighs anywhere from a few tens to hundreds of pounds. The display system is usually custom built, touchy, and too unwieldy to move in angle or rate in degrees per second needed to represent how a target might present itself. Depending on the scenario, the simulated target may well start 'waaaaaaay off to the side of the seeker's POV. So, throw the seeker on gimbals and move it.

Before moving into an expensive HWIL lab, the guidance software, or guidance computer and s/w, will have been put thru it's paces on a computer-in-the-loop simulation, where nothing moves except logic states. HWIL is the final stage of integration testing before trying the whole missile out on a test range.

Re:Hardware In the Loop: Been There

Granted, in general. As a result of the crap the DoD occasionally had to shitcan in mid-development, bids are now supposed to be considered against a matrix of qualities, including price, performance, maintainability, and the cluefulness of the contractor. But, when the THAAD contract was let back in '92, nearly everyone was absorbed with the idea of the Peace Dividend. So, Hughes Aircraft, which had a demonstrated track record with such complex systems got the shaft not only on THAAD, but for post-Gulf War I replenishment of its existing guided missiles in favor of the cheaper, shody crap from the second source provider, Raytheon.

Certainly price is a factor in any defense contract bid. Though now, as another poster stated, things like quality and CMMI and all that are factors as well. But your assertion that your employer would have had a deployable system by now is unfounded. You have no basis to state that you would have solved the technical challenges in this timeframe other than from the "monday morning quarterback" perspective. Missile defense is a challenging problem. You don't just slap together some hardware and send it out to the field and shoot stuff down.

If you're implying mismanagement, then I'd like to hear evidence of that. Projects that go overbudget or have technical delays are not always cases of defense contractor mismanagement or technical incompetence.

And, yes, I work at LM (in nothing relating directly or indirectly to THAAD), but that's beside the point.

• nuclear non-proliferation treaty
• economic cooperation (carrot)
• economic non-cooperation (stick)
• cultural export
• implied threat of nuclear return fire
• diplomacy, including explicit threats
• intercept of suspicious boats and trucks near borders
• intercept of ICBMs at launch (sabotage, airborne laser)
• intercept of ICBMs in space (smart rocks, X-ray laser)
• intercept of warheads reentering (radar-controlled heavy machine gun)
• bomb shelter, good building codes, iodine and calcium supplements

It looks like you want to rely on the first few layers alone. Note that the first 4 have already failed several times. No thanks dude, I'll have all the other layers too please.

Kim Jong Il seems to be stopped primarily by the threat of return fire. I think he likes to keep his comfy palace.

Not every troublesome leader would be stopped. Someday, perhaps Kim Jong Il (with fading mental health?) will not be stopped by that layer.

North Korea isn't the only place to gain nuclear weapons, but fortuanately the "cultural export" and "economic cooperation" layers work damn well against places like India.

Also, watch out with your "work" definition. A layer that works 15% of the time is still useful. It beats having nothing. Don't dismiss something just because it isn't 100% perfect all the time under all conditions. If we could have such a perfect defence, we sure wouldn't need multiple layers! The whole point of a layered defence is to provide excellent protection despite our inability to create any one perfect defence.

Re:the few remaining layers have saved me, so far

[sickofthisshit]

B.S.

Kim Jong Il, if anything, is HELPED by the threat posed by the U.S. It justifies his militaristic regime. You probably think Castro is going to fall any day now because of the U.S. sanctions.

Plus, you TOTALLY ignored the cost aspect. Yeah, it would be nice to have a missile defense capability, if it cost nothing. And then, I might not care that it doesn't work.

I can go wrap my house in tissue paper to make an *in*effective defense against nuclear attack. And it would be cheap. But I still don't do it because it would be stupid. If I had to spend billions of dollars to get gold-plated tissue paper, it would be even more stupid.

Nope. Anyone who they sell/give/distribute the GPL software to must be able to receive the GPL source code at no/minimal cost, should they want it. It does not mean that the software or source code has to be made publically available for all and sundry, who never obtained GPL software from them. They are in their rights to make available CDs of the source code to customers who obtained the software, should they choose to want the code, instead of public download. What the customers do with the code from there is up to them, as long as they in turn honour the GPL obligations.

You should read the Rama series

[Mr2cents]

I recently read the "Rama" series by Arthur C. Clarke (later books together with Gentry Lee). There was a species, I'm not telling wich one in order not to spoil too much, but they had an interesting war policy. When they entered a war, the society was drastically transformed, and *every* individual involved in the war effort was automatically sheduled for termination (aka death) as soon as the war ended. This included their leaders. They immediatly started producing large amounts of offspring to replace them. There were two reasons. The first was that the individuals confronted with war would be emotionally unstable from the horrors of war, and could not adapt to civil life afterwards. The second was that war is an extreme solution, and their leaders would not begin a war needlessly because it meant they would die no matter the outcome.

It was a really cool part of the series, the species would first allow the agressors to bomb them without retaliation while sending multiple messages saying that they didn't realized who they were messing with and that they'd better stop now. Then after the final ultimatum, they were remorseless and would kill nearly everyone in one big blow.

I liked their attitude :-).

PS: The episode is in the final part, Rama Reveiled, so you'll need some time. Also, the ending isn't that spectacular, imho, but still I enjoyed reading it.

The author is "sort of" right. THAAD was floundering badly in the 90's and was completely restructured in 1996. The battle management and sensors were fine, but the interceptor was a flop and completely redesigned.

He speaks of the old system, you of the new. The only thing in common between the two systems is the acronym, but even the first Word in it has changed.

Not to worry, the THAAD interceptor will probably be replaced with the SM-3 (the missile that the Aegis BMD system is based on). However the radars and C3BM will remain the same.

Slashdot: Just another culture war

[TheNarrator]

Amazingly free software has avoided becoming overtly politicized! Probably because software developers are a lot more intelligent than the average "movement".

When I say politicized, here's the long academic, but very interesting explanation of what I'm talking about:

Why everything everywhere all the time must be political.

The short explanation is this:

I was once on a electronic music mailing list dedicated to the subgenre of electronic music known as "Trance". This is just electronic music but more repetitive. Electronic music of this subgenre in general does not have lyrics.

Anyway, the Iraq war was starting and some guy came on the list and said "If you're really a 'Trancer' and believe in the trance music spirit you'll come to my anti-Iraq war protest".

I replied back that if ALL I really cared about was trance music than I would be for Nuking Iraq, Iran and Saudi Arabia and putting the entire middle east under the domination of Israel as Israel has some of the best trance music in the world and raves, techno music, dancing, hallucinogenic drugs etc are treated far more severely in these Islamic countries than in Israel.

Anyway, invevitably every single movement of any size is at least attempted to be co-opted somehow into the left wing political coalition, no matter how tenuous the link between the left's ideology and the aims of the movement they are attempting to assimilate.

Linux and Star Wars...

[healyje]

One stands a half-decent chance at mounting an active defense to protect us despite obvious weaknesses; the other is riddled with technology, design, and implementation holes and is easily overwhelmed by a multiplicity of means. Which is which...?

GOOGLE WILL OWN CHINA GOOGLE OWNS THE WORLD :)

You sir are wong! :) We americans will own China in just a few years. They are dependent on our Google company :)
j/k

What do we care? He who has the larger army and advanced technology rules the world.
Was it Shang Tzu that defined the ways of war in his book?
We're the most poweful nation on the planet.

Most important question

[Omega Blue]

I went to Concurrent's website and couldn't find any free Linux distro to download.

Aren't they violating the GPL?

I'm sure the enemy won't be any less impressed with PWN3D in crappy fonts instead of pretty ones.

Mod Parent Up!

Hear frickin' HEAR!!!! I couldn't agree more with your reasoning and logic. :D

Screaming in the Night

[JhohannaVH]

(when you have the source available, in C, C++, Fortran and ADA),

AAAAAAAAAAAAAAAAAACCCCCCCCCCCCCCKKKKKKKKKKKKKKK!!! !!!!!!!!!!!!!

Could you please go pick up my inner child at the day care center? You scared her back into infancy!!!!

Holy SHIT! I never thought I'd see those all used together like that every again after I left NORAD and College!!!!! ADA is the *whole* reason that I never could program. CTU pushed us from BASIC -> Turbo Pascal -> ADA -> C -> C++ (can you tell how long ago this is yet?). I got *so* lost in ADA I've never been able to write anything other than scripts. :( What's really sad is that my instructor worked at the same company I did, and he couldn't even understand most of what he was teaching. *feh*

Must be a military application! :P

Is it running a GIT kernel, and will I be able to listen to MP3s without skipping? :P

missile defense

[Con to the Spiracy]

Ideologically at least, I support the idea of national missile defense. But one has to look at this from a cost-benefit angle. A system that could probably stop ICBMs would be worth spending quite a lot on (though not necessarily any obscene amount of money). A system that can maybe stop ICBMs under ideal conditions will probably not stop them in real life. It's still worth a lot, but not billions and billions. This is money that could be much better spent actually protecting America. For example, what's to stop somebody from landing a nuke on our shores in a small boat? How many thousands of times less would it cost to patrol our shores effectively than fuel some military-industrial boondoggle?
