In Commentary, Max Boot notices:
The latest Gaza war is only a few days old, but already one conclusion can be drawn: missile defense works. This is only the latest vindication for the vision of Ronald Reagan who is emerging as a consensus pick for one of the all-time great U.S. presidents.
For it was Ronald Reagan who made missile defense a major priority for the U.S. and our allies. His 1983 speech on the subject was widely derided as “Star Wars” because he envisioned that some missile would be intercepted in space. For years critics claimed that it was impossible to intercept missiles in flight, or that at the very least it would be prohibitively expensive to do so. But now the U.S. West Coast is actually protected by a limited ballistic-missile defense system based primarily around satellites, sea-based Aegis and X-band radars, and Standard Missile-3 interceptors. We don’t know how the system would work in combat but it has been vindicated in testing.
The U.S. has also cooperated with numerous allies to develop more tactical missiles defenses designed to stop rockets, not in their boost phase, but just before they hit. One of those projects is the Iron Dome system that Israel launched after the 2006 war in Lebanon, during which Hezbollah bombarded northern Israel with thousands of rockets. Today Iron Dome, which is still officially listed as experimental, is operational–and it is blunting Hamas’s missile-offensive against Israel.
