You know Toronto, call me nutty, but I'm not so sure anyone will.
Given the difficulty of the operation, only the US could actually carry it out.
It would be a massive undertaking though. First, you'd have to prep the Iranian Air Defense Grid, taking it down all along the most heavily defended stretch, the Western border with Iraq. Then you'd have to launch multiple strikes throughout the country, to include research establishments.
The hits on active reactors and plants would inevitably cause massive collateral damage, and probably several fallout problems for neighboring countries. After which the Iranians would have no recourse but to declare war. They'd also go immediately from being the sabre rattling nutters to the poor underdogs in world (not to mention Middle Eastern) opinion.
I think we want them to think we would be willing to pre-emptively strike in order to bring them back to the table. But I doubt that will happen. We'll eventually get some tepid sanctions going in the UN, but I think they will inevitably eventually become the second power in the "Axis of Evil" with Nuclear Weapons after NK.
Whether they decide to use them to vaporize Tel Aviv (and countless Arabs in the process) will be up to their Mullahs.
