For years, Pentagon experts dismissed Iron Dome as doomed to fail and urged Israel to instead try a cheaper U.S. approach.
Iron Dome faced similar skepticism at home. But an Israeli mathematician-general, along with a labor-organizer-turned-defense-minister, pushed the project through, overcoming the opposition of some of Israel's most powerful military voices.
During the recent hostilities with Hamas, the system limited Israeli casualties to six during the seven days of bombardment. As a result, there was less pressure on Israel's decision makers to invade Gaza."If it was not for Iron Dome, for sure you would have seen a more aggressive action in Gaza by air and ground," said an Israel general and member of Israel's joint chiefs of staff.
