Israel has just carried out a major aerial exercise, putting a hundred or so F-15s and F-16s into the skies over the eastern Mediterranean, evidently a rehearsal for a strike against Iran’s nuclear facilities. The move follows the statement earlier this month by Shaul Mofaz, Israel’s deputy prime minister, that an Israeli attack on Iran’s nuclear program is “unavoidable.”

Israel almost certainly knows the location of some of the critical nodes in the Iranian program that it must hit if it is to set the Iranian effort back by several years. It also possesses the technology to assure that its bombs will fall close to or on their targets. But would such a strike succeed?
