wasn't there some sort of change in the US nuclear credo a while ago? Or pending? Saying that the US could use nukes as a pre-emptive striking means.
Anyhoo, like J said, it's really a delicate matter. From iran's pov you have to imagine: a lot of countries who've got nukes themselves -and loads of them too- preventing them to make one. In the eyes of a country like Iran that is both hypocritical and patronising -after all, who's to say the US or France are to be more trusted with their nukes than Iran with theirs?
Needless to say, I prefer -say- France with a nuke than a theocracy like Iran, I'm just saying that from their pov the attempts to stop them make no sense.
It's really all about the double standard used between the West and the rest.
'you can't violate human rights!' ->US has prison camps and death penalty
'you can't have WMD's/Nukes!' ->all big Western countries have them. Heck, Israel has nukes. But does the west mind? Course not.
Ah well...international politics are always a delight. Like with the geneva conventions, everyone does something else than they say they're doing.
Let's just hope we don't die in the process. And of someone gets nuked by Iran or any muslim country its Israel anyway.
