Israel's Iron Dome Missile Defense Shield Actually Works
Hugh Pickens writes "Sarah Tory reports that the debut of Israel's Iron Dome missile defense shield has added a new element to the conflict between Israel and Palestinians in the Gaza strip, one that military officials are calling a 'game-changer.' Israeli officials are claiming that the shield is destroying 90 percent of missiles and rockets it aims at that have been fired into southern Israel by Hamas. This level of success is unprecedented compared with older missile defense systems such as the American-made Patriot model used during the 1991 Gulf War. The missile-defense system can detect rocket launches and then determine the projectiles' flight paths and only intercepts rocket or artillery shells if they are headed for populated areas or sensitive targets; the others it allows to land. It takes a lot of raw computing power to rapidly build a ballistic profile of a fast-incoming projectile, make a series of quick decisions concerning potential lethality, and launch a countermeasure capable of intercepting said projectile in-flight. One reason Iron Dome is showing a much more robust capability than the Patriot system did is simply that its battle control hardware and software are several generations more advanced than those early interceptor systems. 'Israeli officials point out that Iron Dome saves money despite the fact that the interceptors cost up to $100,000 each,' writes Tory. 'The cost of rebuilding a neighborhood destroyed by a rocket attack — not to mention people wounded and lives lost — would be far greater than the cost of the interceptor.' Most important, the system buys Israel time, allowing it to plan out an appropriate response without the political pressure that would be generated by hundreds of potential deaths."
Anyone else thinking they should deploy it on the Gaza side too? Not instead (I know people will misread me). As well.
You mean that SDI might work after all?
That will get us out of the nuclear age. A stop rate of 90% eliminates a first strike advantage.
But what's going to replace mutually assured destruction (MAD) when the destruction isn't assuredly mutual?
These missile shields could bring us closer to nuclear war, or end it forever when the party with the shield tells everyone else to drop their nukes or vanish in sparkly glowing fireballs.
Miscalculation? Mechanical error in the defense? I imagine the margin of error is relatively significant just because it does all of this on the fly, so the best way to get a quick enough response is to guess at a few things.
Given what it's doing, however, I'd say 90% is pretty damned good.
I'm not saying Israel's defenses don't work (I've no reason to think that) but given the timing do you think we'd be told
a) If the defenses didn't work well at all
or
b) About all the instances the defenses failed to work?
Given the circumstances what we hear *especially* from official sources on either side of this conflict should be taken with quite a grain of salt.
So the Palestinians launch missiles at Isreal and you are upset that Isreal is pissed off about it and launches counter attacks? If Canada started launching rockets at the US, I would expect us to invade and conquer them in short order. I'm surprised that Palestine has been allowed to exist as long as it has.
You need to 1) detect the launch 2) determine the trajectory 3) determine the speed 4) determine a few other factors (mass? range? payload? whether it's capable of changing trajectory mid-flight?) 5) calculate where it's going 6) determine if that counts as a populated area 7) fill in any missing variables 8) make a decision 9) direct the defense
How fast could you do this? What if there's a hundred rockets coming in at once? It's not like a dumb bomb that's dropped straight down on a given point.
Yes, both parties are at fault for continuing this ridiculous feud. But is America blockading and occupying Canadian land to begin with? No.
And yes, I'm surprised that Palestine has been allowed to exist as long as it has considering the United States really doesn't give a damn about the fact that Israel continues to bulldoze their homes down for their own settlements.
Let's make it clear, I condone the actions of Hamas but Israel's actions are very heavy-handed in proportion to Hamas' attacks/
Does it really take so much computing power to calculate trajectory of a falling object? I know there's a lot of uncertainty coming from measurements but I don't really think you need anything more than an equivalent of pentium 100 to effectively decide wheter the missile is heading toward a populated area or not.
It depends when in the trajectory it plots the intercept path. If it is during the rocket-propelled phase then calculating the possible trajectories of something that will accelerate for a while then descend is probably a lot. Also the protected areas are likely to be a number of irregularly shaped patches on a three-dimensional terrain, not just one circle.
Then of course you have to calculate your intercept trajectory, again not simple
You seem to have left out the US and Israel funding Fatah to wage a proxy war against Hamas (democratically elected, by the corrupt system that the US and Israel pushed), the IDF killed a thirteen year old boy last month, then a twenty-three year old mentally disabled man who walked too near Gaza. Then, when the PFLP wounded four in a rocket launch near the border, Israel ASSASSINATED one of the leaders of Hamas and the strip.
Just thought you could use that background info.
I wonder what it is about the other 10% that lets them through?
How far do you manage to get in Missile Command? Do you 100% every level up to the 810,000 point, or do you rely on bonus cities?
Wow...you should REALLY read even a tiny bit of Middle Eastern history before making comments like that...also, rely on at least one non-US feed for your news...you do yourself a disservice otherwise.
So the Palestinians launch missiles at Isreal and you are upset that Isreal is pissed off about it and launches counter attacks? If Canada started launching rockets at the US, I would expect us to invade and conquer them in short order.
Well, if the US sent their military into Vancouver for "security" reasons, throwing out all the Canadians who lived there and allowed US citizens to build homes and "settle" the area and considering the US's superior military, I wouldn't blame Canada in the least for shooting rockets over the border.
I'm surprised that Palestine has been allowed to exist as long as it has.
You are either an excellent and crafty anti-Israel troll or an incredibly ill-informed person.
Best missile defense shield : peace treaty.
Reading the comments, it seems I'm the only one here who thinks this is awesome. When it comes to weapons development, this is exactly the sort of weapon we should be cheering for. Whether you agree with the ones using it or not, this is a wonderful thing. A weapon which only works as a shield to block incoming attacks; that is what the weapons used by enlightened countries should have evolved into.
A better example would be if American Indians, subjugated and embargoed on their reservation, started rocket attacks on the US.
It's not a falling object, it has a rocket engine.
You have to estimate acceleration, correct for mistakes, compute a plausible trajectory for it, compute a plausible trajectory for the interceptor, and since it involves objects moving at high speeds, it all has to be very accurate. You probably have a lot of crappy data sources to aggregate (radar, optical, etc) and things like wind and coriolis effects to take care of.
The optimal control problems involving launching and controlling the interceptor are already hard to write down on paper, and solving them numerically is far from trivial. And it all has to be done in real time.
In sum, it wouldn't surprise me if they had a 500-core, state-of-the-art supercomputer crunching the numbers.
One other large difference that the summary glosses over is that there's a big difference between the Katyusha and improvised rockets of Hamas, and the much larger Scud missile used by Iraq. There's almost an order of magnitude difference in size and range, and a several-fold difference in speed.
There's a correspondingly large difference between the Tamir interceptor missiles used as part of the Iron Dome and the Patriot missile.
Still, on the whole, it's probably a good thing that we are getting better at setting our lethal weapons against each other, rather than at people.
There was a huge problem with the Patriot system early on where the tracking computers lost so much accuracy even after only running continuously for 8 hours that the system would fail to intercept threats. The short term solution was to reboot the system at regular intervals.

I'm surprised Palestine has survived as long as it has. Bit by bit, Palestinians are being forced from their homes as Israel expands its lebensraum.
The Palestinians are defending themselves against an invading army. What would you do if the Canadians surrounded your town, marched you out of your home at gunpoint, bulldozed it flat, and told you to get the hell out of Canada?
Holy crap, check this thing out!
Color me impressed...
This same hamas threw fatah members from high floors of buildings when the won their fair elections. I'm not sure elections are supposed to end that way
Dr. Freud just slipped, he may take a moment to answer your page.
Thus, in both a military and an economic sense, MIRVs render ABM systems less effective, as the costs of maintaining a workable defense against MIRVs would greatly increase, requiring multiple defensive missiles for each offensive one. Decoy reentry vehicles can be used alongside actual warheads to minimize the chances of the actual warheads being intercepted before they reach their targets. A system that destroys the missile earlier in its trajectory (before MIRV separation) is not affected by this but is more difficult, and thus more expensive to implement.
Even if you made an iron dome for ballistic nuclear warheads, who ever is firing them at you is just going to make them split right before they hit your interceptor kill zone. And then you'll have less time to act or deploy your interceptors and a random number at each entry point. Could you take out some of them? Sure but it's a clam shell game.
I'm pretty sure Hamas isn't using MIRV technology and the Israelis have developed this Iron Dome tech to stop this specific kind of attack. Not ICBMs with complex nuclear payloads.
My work here is dung.
It's not just calculating a trajectory. I'm not an expert, but I assume it involves at least:
1. Detection - multiple layers of detection systems such as
- radar
- IR
- computer vision / pattern recognition AI
all of these have to work in unison to produce a high detection ratio and eliminate false positives
2. Tracking
- tracking the object during its flight path using the aforementioned systems
3. Projection
- thinking ahead of where the object is likely to strike, a small part of this is the "trajectory calculation"
4. Threat assessment
- use projection data to assess the strategic value of impact location
5. Fire control
- make decision to intercept, if positive
- allocate the most appropriate platform
- check airspace / final safety assessments
- send warnings / signals / fire confirmation
All of this has to happen within seconds.
The fact that those missiles strike crowded residential areas probably has something to do with various Arab organizations launching missiles at Israel from those very same residential areas. When you place military targets in residential areas, those residential areas become military targets.

Heavy-handed? Try showing restraint when your backyard is being targeted by rockets.
That analogy works if and only if you consider Palestinians to be more indigenous than Israelis.
"[Regarding the 'cloud,'] ownership was what made America different than Russia." -- Woz
Palestinians are Christian too.
Are we now separating them into good Palestinians and bad ones?
Kill all the Muslims and let the Christians live? Or just kill them all.
I'll wager the ones firing missiles at Israel are all Muslims. The 0.3% left after their victimisation by the Muslims are keeping well out of it. Of course every effort should be made to minimise casualties of all non-combatants, but you cannot just let someone keep firing rockets at you because they set up in a populated area. That would just reward the Muslims for their disregard of international law and human rights
In those days, rockets were made of thin pieces of wood and launched from a device resembling a stringed musical instrument. As a result of their brazen unprovoked attacks, their civilisations were wiped off the face of the Earth by the technologicall superior interlopers a few decades after arrival. Kind of like the Palestinians. Isolated by the lines that the British drew all over the Middle East, impoverished by a long standing blockade and confined to the largest concentration camp in human history, all the while being bombed, starved and shot into annihilation.
How dare some of them get angry enough to attempt to fight back?
I hate printers.
It's trickier than it sounds. For one, you need good radar to pick those things up and accurately track them. You need to track it long enough to know its trajectory, but not so long that you are left with no time to respond. Then, you have to get your missile to the rocket, correcting for Wind and a possible new trajectory (we are talking about crude rockets, so they can't be too stable).
I have heard about 2/3 rate, not 90% rate. There is little room to independently separate propaganda exaggeration from actual facts.
I do not believe in karma. "Funny"=-6. Do good and forbid evil. Yours, Oft-Offtopic Flamebaiting Troll.
Heavy-handed? Try showing restraint when your backyard is being targeted by rockets.
Israel stole land from the Palestinians. They then allowed their people to build "settlements" on other people's land.
And you're condemning those people for fighting back?!? And obsolving Israel of any blame and condoning their complete over reaction?!?
Israel has lost all sympathy from me.
And people like you are going to keep this shit going on and on and on.
Israel is just living with their own karma. Oh, well. Too fucking bad!
Here's a random question for some knowledgeable person: how much of that $100,000 cost per interceptor is overhead? I realize that missiles aren't simple things, but that strikes me as way out of line with what it would actually cost to build one of these.
That goes for other missiles as well - you always hear about Tomahawks, etc., costing $1 million+, how much do they actually cost to build?
Well, they were just thrown out of office.
When Fascism comes to America, it will call itself Anti-Fascism, and tell you to give up your guns.
I really don't understand the argument against Isreal on this one. They've done a lot of wrong towards Palestinians, especially on the west bank side, but hundreds of rockets are being fired from Gaza targeting civilians. Isreal's assassination was a military target. Maybe they've killed some civilians in Gaza too, which is horrible, but at least accidental. They seem to avoid that when they can. Hamas is firing rockets directly at civilians. You have to see the difference.
Here's a handy diagram that may help to explain things. Try showing restraint when your neghbourhood has been invaded, bulldozed, and then built on.
...we put effort into our own defense...
"You didn't build that..." You had to spy on the Americans and get... how many billions in aid? Let's reduce you both to sticks and stones, and see how well you hold up.
“He’s not deformed, he’s just drunk!”
Only Jews would be dumb enough to try and live somewhere where everyone else fucking hates them, then act in a way to ensure that everyone continues to fucking hate them.
Because they were treated SO WELL in Europe over the years?
Israel assassinated one of the leaders of Hamas
The man who was killed, Ahmed al-Jabari, wasn't just "one of the leaders of Hamas". According to Gershon Baskin, who was involved in Israeli-Hamas negotiations:
"Passing messages between the two sides, I was able to learn firsthand that Mr. Jabari wasn’t just interested in a long-term cease-fire; he was also the person responsible for enforcing previous cease-fire understandings brokered by the Egyptian intelligence agency. Mr. Jabari enforced those cease-fires only after confirming that Israel was prepared to stop its attacks on Gaza. On the morning that he was killed, Mr. Jabari received a draft proposal for an extended cease-fire with Israel, including mechanisms that would verify intentions and ensure compliance. This draft was agreed upon by me and Hamas’s deputy foreign minister, Mr. Hamad, when we met last week in Egypt."
In other words, if Israel had really wanted a cease-fire agreement, they would have just waited for Jabari to sign the deal. Instead, they killed him.
I am officially gone from
The Patriot missiles were known to occassionally follow their target to *its* target.
Aside from just missing, another issue is that even if you hit the target, you need to make sure that your missile detonates when it makes contact with any part of the target.
Finally, detection isn't perfect, trajectories are approximations at the time of launch. The missile needs to adjust using information collected in-flight.
You do realize this is because the missiles being fired into Israel are being fired from civilian areas.
This is but one thing that separates terrorists from soldiers... terrorists hide among the civilians using them as shields and propaganda.
There is little honor to go around on either side of this, but hiding among the civilians is an act of supreme cowardice and Evil.
--- Nothing To See Here ---
I remember how during the gulf war the patriot system was being lauded on news sites as being fantastically accurate, taking out most missiles before they landed, etc.
Only turned out later that it wasn't so accurate.
I'll give it a couple of years before I conclude whether the accuracy reported in the new system is just propaganda or not.
NY Times article has more information than the top link, e.g.: "Iron Dome has successfully intercepted more than 300 rockets fired at densely populated areas, with a success rate of 80 to 90 percent, top officials said."
So a bit lower percentage. Yet I'm skeptical of even that, because we have no independent verification, and officials are incented to cheerlead/bluff for things like this. Also note that it was about half paid for by the U.S. to the tune of about $900 million.
We know where leadership by an anti-intellectual "strongman" who scapegoats minorities and likes boisterous rallies goes
...to Isreal, I think Egypt, Lebanon, Syria and Jordan should cut off all land, sea and air crossings, build walls, install tunnel detectors and disable all Israeli power and water plants.
Occasionally storming with ground troops couldn't hurt. You need to find those radicals who oppose the seige.
When Isreal stops opposing the seige, then the seige will be lifted. But we have to be sure they don't stop temporarily, so the seige should probably end if Isreal stops opposing for a couple decades or so.
Yes, both parties are at fault for continuing this ridiculous feud. But is America blockading and occupying Canadian land to begin with? No.
No, but America did blockade Cuba. Was it at fault that Soviets were trying to place missiles in Cuba? No. The Soviets were at fault. Just as the Arabs are at fault for electing Hamas to lead Gaza. If Hamas wasn't smuggling weapons in order to commit terrorist acts against Israel, Israelis would do what they with everyone else who doesn't shoot at them -- trade and cooperate.
I condone the actions of Hamas but Israel's actions are very heavy-handed in proportion to Hamas' attacks/
You misspoke, but your misstatement is actually the truth. You DO condone the attacks by Hamas simply because you call Israel's actions heavy-handed. Saying that Israel overreacts in self-defense gives too much deference to the attackers.
Go ahead and spew something about propaganda. That's what everyone else who hates Israel seems to do when hear plainly stated facts.
Any guest worker system is indistinguishable from indentured servitude.
Strangely, it's more complicated than that. Isreal was attacked more than once by it's neighbours before 1967. It's not really unreasonable for them to want a buffer zone they control access to around their main populated region.
Well, if the US sent their military into Vancouver for "security" reasons, throwing out all the Canadians who lived there and allowed US citizens to build homes and "settle" the area and considering the US's superior military, I wouldn't blame Canada in the least for shooting rockets over the border.
Exactly. At first, when you learn about a few Arab-instigated wars Israel has had to fight off, you have a little sympathy for their argument that they need Gaza, Golan, and the West Bank as buffer zones as well as a little punishment upon their aggressors, with the notion being that "You'll get this back when you've learned your lesson".
But then you find out that they're displacing the people living in those areas and then just gifting that land to Israeli settlers and you're like "WTF?!?! How are they ever going to undo that? You can't just go to the settlers and say 'Okay. Time to come back home, we are giving that land back to the Palestinians...'".
So, yeah... when Israeli's call those areas "buffer zones" or anything implying that they're temporary for as long as their neighbors are hostile toward them, I don't believe them for a second.
Israel is practically carpet bombing Gaza every time Hamas launches an attack. They're killing at LEAST 10 times as many civilians as the terrorists are. I wouldn't be surprised if Israel was secretly hoping Hamas continued being stupid, just so they'd have an excuse to slowly wipe Palestine and all it's people off the map.
Which is why it's so hard for the rest of the world to not buy into the deluge of photos of dead children, supposedly from Palestine. I mean seriously, I've seen more photos of dead children than the official numbers stated. It seems anti-semitic propaganda is alive and well in 2012.
Hm. I sure haven't.
Then on the other hand, I treat ALL information in situations like this as propaganda, which means I do not trust the "semitic" information one iota more than the "antisemitic" kind.
Additionally, the "semitic" information gatherers only has the information of the weapon systems and their operators, which, to put it mildly, usually leads to quite crappy and low estimates of the civilian casualties involved. So it is not only "anti-semitic" propaganda that is alive and well in 2012.
The correct number is usually somewhere in between.
Humanitary organisations are usually pretty close. And their numbers are horrendous enough.
To not "believe" either side of a conflict at all, is a very dangerous path.
Completely innocent people, including children, going about their normal life, are ALWAYS terribly hurt in conflict.
Especially so when they have nowhere to run, which is the common case here.
That is just a fact. Try go to a war torn area sometime and see for yourself.
Baboons are cute.
When are the Palestinians going to explicitly recognize Israel's right to exist?
Well, technically, when Israel officially starts defining itself as an Islamic country intended (although not necessarily for real) into adopting Sharia law, coupled with a sizable portion of the currently non-Islamic population following suit and converting. Then it wouldn't be possible, from an Islamic perspective at least, to call its government an external power who came to desecrate land that had already been Islamized.
Not that this would be a good thing, mind you, but that it'd achieve this specific goal, it would.
Although I wonder if that wouldn't end with "New Muslim" Jews being persecuted in a similar way their "New Christian" counterparts were in pre-19th century Europe.
Conservatism: (n.) love of the existing evils. Liberalism: (n.) desire to substitute new evils for the existing ones.
Also, a quick glance at the death tolls of each nation can be quite handy in identifying who the aggressor is.
"goofy" rocket fuel
rather than a nice straight acceleration curve, "poison" the rocket fuel so it sputters and weakens in flight on purpose. Yes, the rocket won't be accurate, but I don't think accuracy is the point. Meanwhile, the goofy microaccelerations and microdecelerations would make the rocket impossible to target accurately.
intellectual property law is philosophically incoherent. it is your moral duty to ignore it or sabotage it
No, actually the summary says "the shield is destroying 90 percent of missiles and rockets IT AIMS AT." The system is not aiming at rockets headed toward unpopulated areas. I think what they are claming is that 90% of the interceptors hit their intended target. If true, this is quite impressive.
...must be overjoyed at helping fund this.
Israel IS a war-torn are, which you armchair commentators don't seem to be able to understand.
Sure, people get hurt on both sides. But if we're the stronger party, it's not our fault. If they can't build hospitals fast enough, it's not our fault. If they can't organize a proper military or government, it's not our fault. It's THEIR fault for spending all their effort acquiring and firing rockets instead of working hard to bulid their own state. Israel was built by hard-working Jews, and if the Palestinians aren't civilized enough to do the same, it's NOT OUR FAULT.
If they don't want their civilians to be killed in battle, then all they have to do is not start battles. When these unprovoked rockets enter our country, are we supposed to ignore them just because our military is bigger? That's an absurd proposition. They fire, we respond. It's as simple as that, anyone saying otherwise has anti-semitic agendas. Jews have a right to live, and retaliate when faced with aggression. Why can't the Palestinians go live in some other part of the Muslim world? 1.2 billion of them and they can't find homes? Jews want a homeland too, and Israel is ours. They have enough fucking countries of their own. It's not our fault if none of them can put together a decent economy or political structure. Saudi Arabia has plenty of space, and the government there gets just as much support from the US as we do.
Muslims just want the Palestinians to suffer so they have someone to claim they are fighting for when they blow up towers in New York.
Well, in this case, Iron Dome doesn't have any effect on Palestinian dead, only Israeli dead and damage to Israeli neighborhoods. Presumably, Israel has facts and figures on it's own dead and destroyed property.
Are they misreporting to make their own population feel safer? That is possible, although of a somewhat different quality than lying about killing Palestinians.
I don't want Palestinians dead, but what do you do when people start shooting off rockets at your country? To some extent, the Palestinians need to control their own people or at least keep them from launching rockets at people somehow. Otherwise, it's a bunch of artillery strikes and rocket launches at inhabited areas on both sides.
Agreed, it has to be a two way street. He can't take responsibility for being able to broker ceasefires as and when he wants and then not also blame him when firing starts again. Either he has the power to prevent rocket fire from Gaza or he doesn't, which is it?
An alternative and equally valid reading of the situation to the GPs is hence, if Israel really wanted a long lasting ceasefire, it was clear this guy wasn't going to be the one to give it to them having allowed rocket fire to commence once again against Israel time and time again.
But meh, I don't know why I bother with discussions like this, they're far too partisan to include this kind of rational balancing of alternative theories. Taking a quote from someone on one side of a conflict, and using it as damning evidence against the other side without considering both sides of the argument, is about as stupid, partisan, and ignorant as it gets.
There is something called "proportionality" too. Rocket attacks have taken exactly 28 lives since 2001. Compared to only the Christmas offensive in 2008 that killed over 1200 Palestinians. The planned attack is not because of rocket attacks, it is because there is an election coming up in Israel in about a month. Nothing improves the chances of an incumbent to be reelected as much as a fresh war to show he is tough on the "terrorists."
Football Odds
Actually, it is a relatively cheap computation on modern computing hardware. The specification for many modern tactical intercept systems is that the complete decision cycle has an upper bound of 20-50 milliseconds. You can do an amazing amount of computation on sensor data in that amount of time.
Remember, sophisticated multi-target tracking and engagement systems were built in the 1970s and 1980s with much less processing power than your cell phone has today.
And in fact, if you look at the chipsets used in state-of-the-art terminal guidance packages for hypersonic kinetic intercept of agile targets, they are embedded systems chips that would have been obsolete as desktop CPUs even a decade ago. Think MIPS R3000 or R4000 class CPUs and a modest DSP.
Basically, CPUs can drive computation at a much higher rate than material physics allows targets to change their behavior. We passed the threshold where computation is the bottleneck decades ago.
Buffer zone? That's good. For any German readers out there: that translates to Lebensraum.
And let's not forget that during past conflicts:
Hamas have conspired to lend themselves a false legitimacy by claiming high civilian losses, when in fact they used human shields during ground offenses by deploying armed soldiers dressed as civilians in violation of the Geneva Convention rules of engagement. Hamas leadership has sought shelter underneath hospitals, putting the population least able to defend themselves at great risk. They even used a captured Red Cross vehicle to launch attacks, a flagrant violation of the Geneva Convention. Hamas have used mosques, schools, and civilian homes as hideouts and to store weapons and rocket launch sites or have placed their storage and/or sites adjacent to those dwellings.
The collateral damage was stragetically planned and such tactics had been previously used by Saddam Hussein during Operation Desert Storm of the 1991 Iraq-Kuwait conflict. They have attempted to deceive and manipulate international press and public opinion by staging rocket damaged areas in civilian areas and exploiting image manipulation, and the international press now carefully scrutinizes photographs and sources of information from those war zones.
Hamas has been planning a campaign of deceit from the beginning. While neither side are angels in this conflict, the greater sin is upon Hamas for their deceit.
Eternity: will that be smoking, or non-smoking? I Corinthians 6:9-10
One caveat:
Artillery rockets are so called because they essentially act just like artillery: straight (as in nominally, not linearly straight) ballistic arc. They reason they aren't called "ballistic" is because that word is typically applied to larger, more preciesely targeted, strategic level weapons rather than smaller, tactical scale, primarily untargeted/unguided rocket warheads.
and "ballistic missile" trajectories, even unsophisticated barely targeted ones like the scud, tend to have more vertiacl than artillery rockets; artillery rockets tend to have a more "artillery" like, ie, flatter, less vertical, trajectory. it's still ballistic (scientific term) in nature, but not "ballistic" (military term).
So still using a ballistic trajectory simplifies the math. Big difference from a scud is, being a shorter range, more tactical scale munition, there's less time for the intercept computation.
(scud was considered a tactical scale ballistic missle, but its considerably larger than the ones used in the past week, using .

The only thing thing anti-Semitic that is alive and well is the ignorant people who try and equate any criticism of a nation or of a person to anti-Semitism as if it is impossible that the criticism might be based on a valid concern rather than racist motive.
You see, this is what I don't understand about people looking at this. This isn't a numbers game. Yes, the Palestinians will eat the brunt of any casualties. Not only are they not represented by a military with a systematic defensive capability, their "military" doesn't even really care much for civilian casualties.
Israel is going to have fewer casualties because they're going to be significantly better at preventing attacks on their people. That doesn't mean the threat is not real, nor does it mean that Israel should have to stand for random rocket barrages on their territory. Would there be a ground assault on Gaza if there were no rockets being launched? Of course not. So how is this about the Israeli election, other than the fact that the Israelis are being targeted at a time where everyone knows that they would want to respond strongly to any attack.
I keep hearing about "proportional" response, but honestly, what does that do other than maintain the status quo? And how do you have a "proportional" response to weapons fired from civilian areas? Even the most surgical of strikes is going to hit civilians.
I would like nothing better than for the Palestinians to have a normal economy and have peace, but honestly, it always seems like they have to keep poking Israel with rockets or attacks. And while many Palestinians do not support terrorists like Hamas, many do. I was just struck by reports of "spies" being dragged through the streets, while wondering if perhaps by giving good information for targeting, those same spies may have made it possible to save Palestinian lives by ensuring Israeli strikes are placed as accurately on rocket installations as possible.
In the end, the Palestinians are pawns. They are not served by their so-called defenders, who are basically proxies for Iran and other regional troublemakers who want nothing more than to keep them a distraction so that the world does not turn its attention to their activities. It may be that the only way for them to save their lives is to realize that they exist only to garner sympathy for an otherwise unsympathetic Arab world.
This is unlikely.
Quoth wikipedia:
"Most people with ALS die from respiratory failure, usually within three to five years from the onset of symptoms. The median survival time from onset to death is around 39 months, and only 4% survive longer than 10 years."
So maybe you meant 39 months or somewhat less when you said you wanted him to die of it soon, but this is unlikely; no one really contracts that ailment and passes away quickly. Probably you should have picked another ailment.
What concentration camp? You mean the one with million dollar homes, and a 5-star hotel? Packed with full markets, and Iphone 5's, where the average person gets $60-80k USD in aid every year? Yeah...what a concentration camp. Imagine that, they even have their own and full sovereignty. And could import things as they saw fit, until they turned around and started shooting at Israel. Then both Israel AND Egypt closed the borders and imposed a blockade.
Om, nomnomnom...
As a followup, I think those calling for a "proportional" response neglect the fact that ideology seriously skews what proportional means. How does one have a "proportional" response to a suicide bomber? How does one have a "proportional" response to rockets fired anonymously from densely populated civilian areas?
Quite frankly, the only reasonable definition of "proportional" in these situations is "hurts the other side enough that they will think twice about doing it again". People condemn the Israelis for bulldozing the homes and towns of suicide bombers, for invading by ground, and for carpet bombing areas where rockets are shot from - but the simple fact of the matter is that it takes at least that level of force to get the attention of the extremists on the Palestinian side. Yes, it sucks, and yes, innocent people die, and yes, it's unfair. But "proportional" is in the mind of the attacker, not the mind of the defender, and lobbing rockets tit-for-tat back into Palestine just isn't going to cut it.
That said, I think Israel has a serious problem with its religious nutjob haredim population. They are the primary driver of the idiotic Israeli settlements on Palestinian land, and their extremism and growth as a political power is going to cause nothing but problems going forward. It's not impossible that they will get a political ruling majority in coming years, at which point any prospect of peace or a two state solution will be completely off the table.
My preferred mechanism for dealing with the Israeli haredim extremists in the outer settlements is to finish building the wall on the 67 borders and cut them off from all support. Let them defend the land if they think they can. No government assistance.
