When Bush decided he was going to do it and do it alone if necessary he made it unilateral. Many of the members of the coalition were also either bribed or coerced in to participation. The chances are pretty good all the leaders who willingly participated will get voted out of office at the first opportunity, Spain already having done so and Australia may well towards the end of the year.

      Well, there actually is a component of religion in the mix. Islamic leaders are very concerned about the corrupting influence that our immoral society is having on their own people. Our sort of cultural imperialism is arguably *more* threatening to them than a few bombs, if you keep in mind that to them (as well as to many serious adherents of other faiths, like Christianity), death is not nearly as bad as damnation.

      As a Christian, I look around our society and have to sympathize with them on that point, at least in part. Particularly when I consider that their view of our society is primarily the one portrayed by Hollywood.

      And 9/11, of course, was not at all about innocent civilian deaths, it was mostly about trying to get the infidels out of the Holy Land (Saudi Arabia). Bin Laden's major beef is the fact that the Saudi Royal family invited drinking, porn-viewing US soldiers and their flesh-revealing women into Mohammed's sacred land.

      In fact, very little of the Middle-Eastern terrorism has been in response to American attacks on innocent civilians. The hatred is largely created by cultural imperialism, support of Israel and various apparently anti-Arab actions taken by the US government over the last 30 years in the process of fighting the cold war and suppressing Iran and Iraq.

      Of course, the civilian casualties of these actions just serve to reinforce the perception that America hates Arabs. That plus the religion-based fears plus the political disagreements leads to all of the Great Satan rhetoric and the moral "justification" of terror attacks.

      Be careful not to fall into your own groupthink and excessive simplification. The causes of the situation are many, varied and complex, and there is plenty of irrationality, self-serving and blind disregard for human life on both sides of the question.

      Overall, I think we need to be more sensitive to the Arab world, and less heavy-handed in our approach to international relations around the globe, but I think that there's ultimately nothing we could do that would erase the fear and hatred. Middle-eastern societies are in the grip of their own great internal turmoil, as they attempt to decide whether they're going to be Islamic or secular, whether they're going to join the rest of the world in the materialism we call progress or whether they're going to stay "pure". America is the ideal symbol for one side of this conflict, and much of the hatred directed our way arises from that struggle, over which we have no direct control.

      Over time, the Middle East will eventually join the rest of the world, become secularized, progressive, open and democratic. Why is this inevitable? Because that's what the vast majority of people individually want. In the case of devout and semi-devout Muslims, they also want to honor their religion and obey their religious leaders -- who do not want secularization and progress, and see that openness and democracy lead to empowerment of the common man who will act against his own best interest (in their view). But, over time, the desire for individual freedom and economic progress will push these societies away from religious control.

      Just don't expect the change to be painless, or to stay within the Islamic nations' own borders.

      Finally, it's also important to realize that everything I've said here is a sweeping generalization. The Arab nations are not a unified whole. Iraq is already very secularized (was prior to Saddam, and during Saddam's reign, although he used religion), Iran is very Islamist, Saudi Arabia is Islamist, but still trying to be progressive, Egypt is a melting pot with lots of factions and counter-factions, and a government that is secular. I don't know enough about Syria and Jordan to comment, but I'm sure they have their own, unique situations.

      Sadly, even if the US did create a landmine that would turn inert over time, there are a number of other nations in the military sales business that would not bother to do so.

      Certainly cost is a factor. Why buy a mine that goes dead after a period of time when you can buy two mines that don't for the same money?

      The idea of self destructing landmines is completely counterintuitive not only to the nature of war, but to the purpose of land mines as well.

      Landmines today are engineered to not kill a soldier (I do not know about US made landmines or if this is regulated by treaty as hollow point bullets are), but rather to cause horrific harm to him. In fact, there is one landmine that when it is triggered it launches itself in the air about waist high and then explodes.

      This deeply injures a soldier in a sensitive area. The purpose of doing this is to not only take him out of action, but to tie up resources to take care of him. But most importantly, it demoralizes those around him and those that come in contact with him. If it kills the soldier, the landmine is considered a "failure".

      Which brings up a larger issue of "war". There are no rules in war, period. War is the distillation of evil from the human spirit, with the purpose to cause (usually hurtful) harm to another human being. It might be a "just war" with a purpose (stop Hitler), or it might be "just a war" with the sole purpose of killing (Rwanda).

      Either case, the enterprise of evil is present.

      Which is why you find toys that are actually explosives so that kids will find them.

      In this context, will a new type of landmine be invented that turns inert?

      Yes, it will. But they will be so few in number compared to other countries that don't care, who will produce countless millions that don't turn inert. So, it could be argued that any such effort is doomed to be meaningless.

      As an aside, I don't excuse what is happening in Iraq with the prisoners of war. But people forget a couple of things. First, it is a war . By definition this kind of thing is going to happen. People would like to think that American soldiers are above this behavior. But the fact is many of those prisoners have American blood on their hands, and many families here in the US will not see their loved ones again because of it.

      So, from my perspective, I can see where if you had a buddy killed by a rebel and you manage to catch him, you might want to exact a bit of vigilante justice to show your displeasure.

      In fact, when Americans captured such prisoners at the turn of the last century in wars, they were routinely lined up against a wall somewhere and shot. Another thought was never given to it.

      I don't fault the Bush administration for going to war with Iraq. I fault the Bush administration trying to fight a "polite" war, to in some way rid the Iraqi people of the evil of Saddam and bring democracy to the Arab world. As some have said, you can win the war, but not necessarily win the piece.

      The purpose of war is to inflict pain on, conquer, or kill your enemy. So, the goal of this war, "to help" the Iraqi people, is incongruous with the definition of war itself. Hence, this incongruity has produced instances of abuse in the Iraqi prisoner of war population. It was not the first, nor will it be the last time it happens. I dare say even by other American soldiers at some future date.

      I am not saying that it should be accepted or excused. What I am saying is that war is an evil enterprise, no matter how smart your bombs are, or if the landmines are self destructing. And when people are fighting a war, I think it would be safe to assume that whether a landmine will turn inert at some future date or not is the very last thing on their mind. They just want it to explode when somebody steps on it.

    After a little while people realised that since a HEAT warhead did not rely on kinetic energy to punch a hole thru armour, lighter, manportable anti tank weapons could be designed and built - including the US bazooka, the british PIAT and the german Panzerfaust (the worlds first disposable anti tank weapon). Shells fireing HEAT warheads was also fired from guns of virtually any caliber during and shortly after WWII.
    Relatively soon however, it was found that composite armour and, to a lesser extent, spaced armour was efficient in protecting against both HEAT and HESH shells, signaling a return to the solid penetrators - now fired by guns that could achive much higher muzzles velocities than the pre WWII designs. For manportable weapons however, it was difficult to increase the velocity of the weapon without making it larger, heavier and thus more difficult to transport and operate. Therefore the wast majoity of the manportable anti tank weapons, including the M72, the RPG-7, the TOW missile and many, many more, still uses HEAT warheads - and is likely to do so for the forseeable future.

    So each 60seconds we accelerate 7+ tons of bullet metal to Mach 9 ... using KE (kinetic energy) formula we give it 30 thousand-million Joules of energy @ 500 million Watts (about the output of 5 large electric plants). ... They're going to need big batteries!

    [*> that is the bullet has moved ten times it's length before the next bullet sets off]

    PS: I'm sure someone will find a mistake in these calculations and that someone else with more gun knowledge will correct some horrible assumption, but hey.

      No to mention that, if Newton got his apples right, you'd have an incredible thrust is the oposite direction. Now, the A10, which boasts a considerable firing rate off it's cannon already slows down a bit when firing... I can envision some aircraft going backwards with this one! ;)

      First - essentially no reload time since all the bullets are stacked directly in the barrel before firing begins. Reducing your estimate by a factor of 10.

      Second - as others have pointed out the electrical charge merely ignites the propelant rather than providing the impetus. Reducing your estimate by another factor of 100.

      Third the weapon only fires for milliseconds when at full rate, reducing your estimate by another factor of 50.

      Fourth - the million rate is developed by a weapon that has about 50 barrels, so the velocity of each bullet can drop accordingly, reducing your estimate by another factor of 50.

      Your last sentence was the most correct, it's the assumptions that invalidate our calculations at least by a factor of 2,500,000.

      This isn't a new problem.

      After the D-Day invasion of Normandy (in WW2) the bulk of the German Army was nearly encircled, but was allowed to escape beacuse the Allies did not want to risk the friendly fire casualties that would have resulted from completeing the encirclement.

      Lobster, I'm of the same opinion concerning Friendly Fire that you are, but:
      - The great majority of the German army was never in France. Only 1/3 of the Wermacht was on the western front which includes all forces in southern France & Italy as well as the forces in Normandy.
      - While Friendly Fire was feared & factored into plans, both Monty & Patton tried hard to close the Falaise pocket. The historians I've read attribute the failure to trap the German forces to german proficiency (being the first users of blitzkrieg they knew what getting encircled entailed) & allied exhaustion (breaking out was a Major effort. Sealing off the forces was beyond them).

    Just watch Iraq. The US have an overwhelming military advantage there. Nothing in the whole country can even dent an Abrams tank. The US soldiers have the best protection, the best fire power, the best communications, recon etc... Yet they are slowly losing control of the situation.

    Those futuristic weapons are designed to fight 20th century's wars, not today's or tomorrow's wars. What's the use of a gun that fires a million rounds per minute when you're trying to control a riot? How can space darts help you identify the terrorist hiding in the crowd?

    Overwhelming weapon superiority does not work in Iraq; I don't think further increasing this superiority will work better.

    I knew a guy that worked at White Sands in the early 90's. His project was the rail gun. One evening he brought a few thing by my work and showed me the possibilities. A 5mm plastic BB, not even hard plastic, and a 4inch square of 2 inch thick aluminum with a one inch dia. hole in it. The gun accelerated the BB to mach5 and it went throug the plate like a knife through butter. Very impressive technology.

    This kind of research goes on all the time, it does advance science. Wheather it ever gets used or not, who knows. Once the technology gets developed it can be adapted to other uses. Anyone think the space programs computer research was wasted? While your sitting in front of the result?
