BIBI needs to do the math and we need to use a little common sense. If Iran did develop a bomb and perhaps a intercontinental missile would he have the lack of common sense to launch against the US or Israel, I don't think they would want to bring the destruction of Iran to watch just one of their bomb blow.
The danger here is that a nervous Israel strikes out on their own to destroy Iran. What then would we do? I for one say you started it I hope you can finish what you start , but were not going to play.
