Dr. Dov Zakheim, who has served in senior positions in the Pentagon under several administrations including the present one, thinks Israel should not carry out a pre-emptive attack on Iranian nuclear facilities. "There are two problems with the Iranian question," Zakheim told Ynet. "An Israeli attack would cause the world to continue to think that this was an Israeli problem, and this will lead to a situation in which no one lifts a finger to solve this problem," he said.
"That means that Israel will need 100% certainty of the attack's success, because in five years' time, maybe even less, the Iranians will be back," Zakheim explained.
When asked how he thinks Israel will be able to defend itself against nuclear-tipped Iranian missiles in the future, Zakheim noted that Israel has a defensive array with radar and "Arrow" missiles, and that the U.S. could supply Israel with anti-missile missiles for intercepting longer-range ballistic missiles.
