No sane country, that's for certain. But when nukes are in the possession of national leaders who believe in stuff like "the returning 12th Imam" and receiving heavenly virgins for killing infidels then we've got a big problem. Obviously we'd win any such war, but at what cost? ...a few major U.S. cities? That's why we can't allow nuclear proliferation in the Muslim world.
I think human nature is no different in the middle east than anywhere else, the leaders use ideology and hate to control the masses and keep their power, they likely don’t really believe in the junk they spew, and the last thing they want to do is risk loosing their power and lives (they are cowards) in a war, nuclear or otherwise with the United States, IMO.
