Tell me what we should have done to stop Hitlers march on Europe, because the Germans sure weren't stopping Hitler's March. If you're going to lay blame, lay it where it belongs.
We could have changed the conditions in Germany that led to the rise of Hitler. It's called being proactive and not reactive. The seeds of WWII started at the end of WWI. The Allies had almost 20 years to change their behavior and failed to do so.
