LOL Thanks for the laugh. Iran has no nuclear weapons, no way to get them to the USA if they did, absolutely zero reason to do so if they did, and a huge American nuclear arsenal to deter them anywise. It deterred Mao and Stalin, who were vastly more a danger to the USA than Iran could ever be. And of the course there's the fact that Iran is one of the world's more peaceful peoples, they haven't attacked another nation for centuries.
This question is silly even by comic book standards, Faux News watcher I assume?
