The Nazis where only 'smart' in terms of propoganda. They put on a big show for their people and made themselves look MUCH stronger than they really where.
Hitler was evil. He killed millions of innocent people simply because he had developed a grudge while living in Vanace.
Osama was not exactly good.
however the western world is no more heroic or ethical than the rest of the world. Our idea of 'liberating a coutry' is to go in and bomb a school or two. We have this idea of 'fighting for piece' which is a no win situation. That's pretty much what everyone is thinking, so we end up fighting each other for piece. Which is utterly pointless. It's like throwing oil in a lake to stop pollution.
