And who were the Germans following when theystarted WWI?
It was'nt Hitler.
So it's not the leader that causes wars. Its the leader that takes advantage of the situation to propagate war. People are people, and I doubt the Germans have evolved in the span of 90 years. They no better or worse than the rest of the world.
There's a reason they are balking on Iraq, and it has nothing to do with past wartime experiences.
