Imagine reversing the situation between Iran and Israel. Noam Chomsky sketches it out:
Iran is carrying out a murderous and destructive low-level war against Israel with great-power participation. Its leaders announce that negotiations are going nowhere. Israel refuses to sign the Non-Proliferation Treaty and allow inspections, as Iran has done. Israel continues to defy the overwhelming international call for a nuclear-weapons-free zone in the region. Throughout, Iran enjoys the support of its superpower patron.
Iranian leaders are therefore announcing their intention to bomb Israel, and prominent Iranian military analysts report that the attack may happen before the U.S. elections.
Iran can use its powerful air force and new submarines sent by Germany, armed with nuclear missiles and stationed off the coast of Israel. Whatever the timetable, Iran is counting on its superpower backer to join if not lead the assault. U.S. defense secretary Leon Panetta says that while we do not favor such an attack, as a sovereign country Iran will act in its best interests.
