The one missing piece of logic in worrying about an Iranian attack is the inevitable size of the fallout. Considering the size of Israel, would Iran not risk killing millions of its allies that are the current antagonists to Israel?

I can see bunker-buster sized munitions, but in reality how utterly stupid do the Iranian mullahs have to be to kill the people they are trying to aid in the Palestinian/Israeli conflict?

Even assuming they are in this struggle just to dominate the region, would they not just put a huge bullseye on their country once such an attack occurs?
