First, as for the whole Hitler vs Gandhi discussion, it is a silly and ridiculous scenario and has no porpouse on our current discussion. I hardly think that a raving lunatic Adolf Hitler, killing apathic Gandhis with a machine gun in such a bizarre hypotetical world has anything to do with our discussion. besides, after he travels all around the world killing people, and clone himself (as we all know, Hitler was a cloning scientist as well), and kill everyone, what was he going to do? Dance and laugh, shooting in the air?! Hitler did what he did because of other reasons. Stalin did what he did due to other reasons.
I have to quote this. It's the funniest thing I've read all day, and it was basically what I was trying to say in my last post, but you nailed it.
EDIT: However, it's become so silly and such a funny idea that I'm tempted to make a new thread for pitting together ridiculous combinations of world leaders to see who'd win in a direct fight.
