You sure don't know what you're talking about. Germany didn't cause or start that war, it was started by Austria. Germany was dragged into it due to a pact they had with Austria. Later, after they got defeated, the Germans got blamed for everything while the Austrians got away with it without having to pay any reparations at all. The Versailles Treaty should have targeted Austria, not Germany. WW2 is a direct result of this failure, ultimately it is the western allies who are to blame for WW2, they forced Germany's hand.
