Not to mention the fact that it was the wrong question. An Iranian nuclear attack on Israel will be met by an immediate, devastating response from Israel. They’re not going to wait for the US. Iran’s remaining capabilities, and there terrorist reach outside Iran is substantial, will be striking at US interests as well as Israeli. The real question is, presuming we allow Iran to acquire nuclear weapons, how will we react to what will be an imminent threat to American interests should a nuclear exchange be imminent. Hillary came close with her proposal to provide a defensive shield to the region in the event of an Iranian attack, a very good idea but one which would have to be backed up with assets, including an anti-missile shield in the region, for Iran to take it seriously. And since she’s in withdrawal mode, it’s really no proposal at all.
