@Dear Krellin,
From other thread I know by now how much you love Putin. This combined with your message about Hitler gives me quite the impression about the men you like. But just as Putin is, Hitler was a mad-man. Hitler failed strategically BIG TIME, so there's that. In terms of "doing awesome things" I have to disagree as well. I take it that you mean other things that created a system of killing people by the millions and actually making money of it, which while a disgrace to human race, was quite impressive in fact. The rest was just as close to a dream of a madman as holocaust, but much less effective or efficient. The history of Nazi Germany is littered with examples of how he got fixated on one particular idea, often extremely costly, that would never turn out to be as useful or successful as planned - V2 and even more ridiculous V3, the railway guns, fortifications in Norway, whole campaign against Russia, all just to fulfill his whims. All tyrants share the love for huge projects (Sochi 2014 ?= Berlin 1936), but as it turns out those project almost never deliver.
