Bombing Iran would be the single stupidest thing that Israel and the US have done in the region. It would entrench the regime, trigger a missile blitz on Israel that the nation had never seen before in it's history, plunge an already unstable region into war, and burn away all the limited progress Obama's made to building good will with the Middle East, and worst of all not really do anything to stop Iran from getting the bomb. Obama isn't stupid enough do something like that right before an election.
