Any Israeli attack upon Iran would invite retaliation, not only upon Israel but upon American targets in the gulf. Most vulnerable would be Americans in Iraq. It won't matter if America is actually complicit or not since America is the one who supplies Israel's military, no questions asked. If Israel were to put Obama (and America) behind the eight ball with some stupid attack, it will blow up in Israel's face. America won't be sucked into another mideast war by Israel and the American tax payers who usually ignore Israel will turn upon Israel and (and their American politician stooges) with a vengeance.
