MIT's Ted Postol Presents More Evidence On Iron Dome Failures

Lasrick (2629253) writes In a controversial article last week, MIT physicist Ted Postol again questioned whether Israel's vaunted Iron Dome rocket defense system actually works. This week, he comes back with evidence in the form of diagrams, photos of Iron Dome intercepts and contrails, and evidence on the ground to show that Iron Dome in fact is effective only about 5% of the time. Postol believes the real reason there are so few Israeli casualties is that Hamas rockets have very small warheads (only 10 to 20 pounds), and also Israel's outstanding civil defense system, which includes a vast system of shelters and an incredibly sophisticated rocket attack warning system (delivered through smart phones, among other ways).

    So, "5% effective"...

    As TFA description reads, the number of Israeli casualties is mostly due to a combination of factors, including bomb shelters and early warnings...

    I think the "Iron Dome" people would respond to TFA thusly:

    "Yes, but **the program** is effective. "Iron Dome" is our missile defense system, which is one part of our civil defense, which is an entire program of things to keep people safe...if you look at the program in its entirity it's a success"

      Actually his assessment is simply based on a false premise.

      What performance characteristics make a rocket defense effective? To successfully intercept an artillery rocket of the type Hamas has been firing, an Iron Dome interceptor must destroy the warhead on the front end of the rocket. If the Iron Dome interceptor instead hits the back end of the target rocket, it will merely damage the expended rocket motor tube, basically an empty pipe, and have essentially no effect on the outcome of the engagement. The pieces of the rocket will still fall in the defended area; the warhead will almost certainly go on to the ground and explode.

      The Iron Dome's purpose is not to destroy the rockets mid-flight, its to protect the population centers. If the rocket is damaged and blows up a parked tractor in the farm field, mission accomplished. If the rocket is damaged and falls on an empty farm house, mission accomplished. If the rocket is damaged and falls on a school, ok yeah we can call that a failure.

      Interesting, lets read the link then:

      So where did the rockets go? Well, according to Israel, they went right back to Hamas. As an official told The Times of Israel:

      The rockets were passed on to the government authorities in Gaza, which is Hamas. In other words, UNRWA handed to Hamas rockets that could well be shot at Israel.”

      Ok, that sounds damning, but lets read till the end for the buried lede:

      On Monday afternoon, Chris Gunness, the spokesman for U.N.R.W.A., denied that the rockets went back to Hamas.

      UNRWA did not give the rockets to Hamas. The rockets were taken away by bomb disposal experts that were answerable to the newly formed government of national consensus, which Hamas has left."

      So the rockets went to people most likely hostile to Hamas. Now maybe the UN could have done better disposing of the bombs themselves, but a UN bomb disposal mission in Gaza sounds like something that could also go really wrong. Remember the role of the UN isn't to fight for Israel, in that case they're just trying to provide humanitarian aid.

Second, Postol (and Lloyd and others) assert that the falling warheads aren't large enough to do damage. But mortar shells do substantial damage and then contain, even using Postol's numbers, perhaps 1/20th the TNT. That's enough to blow big holes and kill a lot of people. Where are the holes?

    we should stop for a moment and listen to Hamas; we may even be permitted to put ourselves in its shoes, perhaps even to appreciate the daring and resilience of this, our bitter enemy, under harsh conditions.
    Read the list of demands and judge honestly whether there is one unjust demand among them: withdrawal of Israel Defense Forces troops and allowing farmers to work their land up to the fence; release of all prisoners from the Gilad Shalit swap who have been rearrested; an end to the siege and opening of the crossings; opening of a port and airport under UN management; expansion of the fishing zone; international supervision of the Rafah crossing; an Israeli pledge to a 10-year cease-fire and closure of Gaza’s air space to Israeli aircraft; permits to Gaza residents to visit Jerusalem and pray at the Al-Aqsa mosque; and an Israeli pledge not to interfere in internal Palestinian politics such as the unity government; opening Gaza’s industrial zone.

    These conditions are civilian; the means of achieving them are military, violent and criminal. But the (bitter) truth is that when Gaza is not firing rockets at Israel, nobody cares about it. Look at the fate of the Palestinian leader who had had enough of violence. Israel did everything it could to destroy Mahmoud Abbas. The depressing conclusion? Only force works.

    True, after Hamas started firing rockets, Israel had to respond. But as opposed to what Israeli propaganda tries to sell, the rockets didn’t fall out of the sky from nowhere. Go back a few months: the breakdown of negotiations by Israel; the war on Hamas in the West Bank following the murder of the three yeshiva students, which it is doubtful Hamas planned, including the false arrest of 500 of its activists; stopping payment of salaries to Hamas workers in Gaza and Israeli opposition to the unity government, which might have brought the organization into the political sphere.

  6. Definition of a successful intercept... by David_Hart · · Score: 5, Interesting

    It seems that Ted Postol defines a successful intercept as one where the opposing warhead is completely destroyed in mid-air and doesn't count a rocket being damaged enough to be knocked down over an area where it can detonate harmlessly. He also relies on personal and public photos and reports to draw his conclusions. This would miss a good portion of the rockets fired as most are fired at night, when photographing rockets and interceptions are much more difficult.

    I'm not going to argue that he is right or wrong. It just seems to me that his extrapolations are not based on enough factual evidence to draw a conclusion with any amount of confidence.

      The rockets generate more psychological damage then physical. As far as weapons go, they are rather pathetic. All the iron dome really has to do is to make those it protects feel safe. If statistics have the potential of damaging this feeling of safety then you ca be assured that they will be kept secret.

      The other purpose of the iron dome is to limit the desire to fire the rockets in the first place. If one thinks their efforts are in vain then they are less likely to follow through. If Israel can convince members of Hamas that their rockets are not working then there will be fewer rockets launched at Israel.

    The way he defines success and failure is framed to say all missile defense fails.

    Iron Dome uses a combination of a proximity (radar activited) fuse and fragmentation. Sometimes the interceptor destroys the warhead. Sometimes it causes an explosion of the propellant which destroys the warhead. Sometimes it simply breaks the incoming missile or rocket into segments or destroys its ability to follow its planned ballistic path. According to Lloyd and Postol, if the warhead isn’t destroyed the interceptor failed.

    You don’t need a Ph.D. to see the immense flaw in this logic: if someone fires a missile at you and you aren’t hit that is good news.

    The Israelis are there. They aren't going anywhere, and they don't like the rhetoric that has been thrown at them about being cast into the sea. They remember genocide, and they aren't going back to Diaspora. The rocket attacks on the cities will only increase the resolve of a people who have the history that the Jews have.

I think the Palestinians would have the most advantage from ending the struggle and adopting a policy that might actually net them more gains and fewer deaths of their own people. If Israel persists in extremist settlements and reprisals when there is nothing to reprise against, they will lose the support of their allies, and they need their allies.
