on a serious note, Hitler rescued Germany from economic malaise through his own form of Keynesian stimulus - rearmament. he broke the back of hyperinflation and followed the policy of autarky. although autarky isn't exactly a formula for economic growth, Hitler's switch to self-sufficiency was not an economic choice but a strateigic one. He knew that he would follow a policy of military domination, thus that policy was the right one for that situation.
He stirred a nationalistic fervour which pulled the great German nation out of the financial woes of the great depression. He filled the political vacuum extremely well and his promises to the people certainly did not go unfulfilled. Maybe he wasn't a humanitarian, it just so happened that the nutter was a rabid anti-semitic, trigger-happy German who was remembered only for his disgusting policy of genocide and racial superiority.
I see the point that he was a strong, successful politician that turned around Germany, but of course, that does not in the slightest, excuse his crimes against humanity.
