No one expects the world to sit back in fear while the mullahs become a nuclear threat.
Expect or not expect, the failure of the Iranian people to fight for their own freedom means the US and responsible countries will have to take the nuclear potential away from the crazy mullahs so that they cannot bully others. It'd be fine if the Iranians would fend for themselves to become a free country, but if all we're going to get from them is pious words and pipe dreams, then men of action will have to act to save lives. If the Iranians cannot accept that, it's too bad. The whole world should not have suffer in fear of a clique of crazy mullahs because doing nothing strikes some in Iran as better than taking out these dangerous weapons.
