i pretty much agree with LSOC. in a perfect world, no one would have nukes. in a perfectly fair world, everyone would have the same amount of nukes (or nukes per capita, idk). the iranians are (sort of right). it's not fair that they have nukes and their neighbors/enemies don't.
but in the world we actually live in, the US would be dumb as crap to advocate for a nuclear Iran. it wouldn't help the US at all.
