Why do we got nuclear weapons anyway... The only real use they have is threatening eachother for wich the bombs itself don't really have to exist. Maybe another good use for it is to blast away some evil aliens or destroy a comet that comes to close to earth, but we don't need so much (or there have to be very many many bad ugly aliens).
If we're going to use those bombs on ourselfs we probably get some kind of 'wargames' situation, how futuristic it is in a movie, because of a million chains of revenge. Those nuclear bomb are pretty much outdated now... They're 50 years old, almost everybody could make them (every country or state). erm... well hope that made some sence
