Waging war is a complicated matter, including technologically. But it looks like within a few years Israel will be better protected from these sort of nasties than anywhere else in the world.
Barak advocates what he calls a "multi-layered" missile defense, with a
combination of complementary systems affording protection against attacks from
just a few kilometers to over 1,000 miles. Ideally, the Phalanx would cover
threats up to around 12 kilometers; the Iron Dome, being developed by Israel
Defense Industries' Rafael and scheduled for operational deployment early next
year, would deal with Qassams and Katyushas fired from between 4 and 40
kilometers; the American-made Patriot Advanced Capabilities or PAC-2 already in
operation, and David's Sling (a.k.a. Magic Wand), being developed jointly by
Rafael and Raytheon and scheduled for deployment in 2012-13, would meet
medium-range threats like the Iranian-made Fadjr 3 and 5, Zelzal 2 or the Syrian
Scud-C from 40 to several hundred kilometers; and the Arrow, which could also
provide cover against the Zelzal or the Scuds, would take it from there for
longer-distance missiles, like the Shihab.
Barak sees the creation of an anti-projectile shield around Israel as a "strategic goal." Not only would it protect civilians and strategic installations, but the knowledge that their missiles might be intercepted could deter potential aggressors from using them.
An effective missile shield could also give Israeli policy-makers added
options: For example, they might feel more confident about withdrawing from the
West Bank if they believed strategic installations like Ben-Gurion Airport were
adequately protected against rocket attack.
Because it's more threatened, one might add.
