And the last fun thing to ponder: how secure are the nukes in the world actually? Could any guy you take from the street actually launch one? Now in the movies you see passwords, security protocols and other crap, but I would hazard a guess it's all massive lies. You just need to think about the reality of MAD. You have your radar operator in Russia, US or China and he sees a mass of ICBMs flying at you. Now your own nuclear arsenal is basically enemy's priority numero uno. If they can destroy that crap, they basically won the nuclear war without triggering MAD (now of course there are submarines with nukes and other countermeasures, but as far as I know majority of the arsenal is in silos). So what you need to do at this point is to launch that shit as soon as possible. This is basically the last moment you want to fumble with passwords and keys and other crap, you need those rockets in the air and flying. You basically need any guy you take from the street to be able to launch that stuff as quickly as possible.
