Israel conflict question?

While I don't necessarily think Iran would use nuclear weapons immediately (maybe hold Israel hostage through nukes and rhetoric), the fact of the matter is that Israel, whether you love her or hate her, will be FORCED to act in the event of Iranian nuclear development. Ahmadinejad has stated his supposed intentions for Israel many times, and the Israeli government is more than used to playing hardball, so a terrifying amount of lives are on the line, both Jewish and goyish. A nuclear exchange is... a bad thing.
