Check out the Treaty of Versailles
and try to imagine yourself being a German patriot or any patriot. It was extremely humiliating, considered outrageously unfair by the German population and when Hitler came to power he reversed the effects of the treaty step by step and - like Khan - gave Germany order. Unfortunately he didn't stop there but was seeking revenge.
