Iron Dome is an air defense missile system developed by two Israeli firms with support from the U.S. Emphasis on defense. It is never used to attack or retaliate and poses no threat to Palestinians.
The system has three components: a radar that detects incoming rockets; a command-and-control system that determines the threat level; and an interceptor that, if the system determines human lives or infrastructure are at risk, seeks to destroy the incoming rocket before it strikes.
According to Israeli officials, it is about 90% effective in stopping short range rockets fired by Hezbollah terrorists next door in Lebanon or Hamas and Islamic Jihad terrorists in neighboring Gaza. The system protects Israelis of all backgrounds and faiths.
For example, when Hamas and Islamic Jihad fired more than 4,300 rockets from Gaza into Israel this past May, more than 1,500 targeted heavily populated areas, including Israel’s largest city, Tel Aviv. Iron Dome shot down more than 90% of those rockets, greatly reducing the death toll. Even with Iron Dome, about a dozen Israelis were murdered. That number would have been much higher without Iron Dome.
It also saves Palestinian lives. Giving Israel a viable option to defend itself shifts its focus from a strategy of preemptive offensives against terrorists who hide among tightly-packed civilians areas to a defense system that intercepts real and present danger. It also reduces the need for ground operations in and around the civilian areas that terrorists use for launching missiles and rockets at Israeli civilians. Often ground offenses result in greater loss of lives.
