I was simply exaggerating, but Hitler was no idiot, just crazy, 'evil'*, and really, really stubborn. He knew how to push people's buttons in just the right way, and he had some of the most genius plans to bring a country out of the economic hellpit that was 1930s-40s Germany, but he never really got to the best ones before blowing his head off...
We can also thank him for inspiring the Allies to make mines that look like camel poopoo. (true story)
*although, if you've read the religions thread, you know I don't believe in true evil...
