Israel’s Iron Dome Works—for Now

When terrorists in Gaza fired some 450 rockets at Israel last month, the Iron Dome anti-missile system kept the damage to a bare minimum, intercepting at least 86 percent of the incoming projectiles. But it would be both more difficult and more expensive to maintain such a success rate if Hamas and Islamic Jihad were to succeed in upgrading their missiles with precision-guidance technology. The consequences would be even worse if these groups were joined by the various Iran-backed guerrillas in Syria, Lebanon, Iraq, and Yemen, at least some of whom already have such weapons.
