He is the man most responsible for the destruction of Western civilization.

Jews and especially the central banking families hold that title.

German atrocities committed during it permanently

'Atrocities' are common during war and the German military conducted itself honorable compared to most armies in history. Most 'German military atrocity' porn is stirred up by western media that was bought off by central banking. Media is an extension of the central banking cartel. If your nation rejects central banking fiat it's targeted for destruction. I'm curious what you would have done in Germany's position?

it permanently discredited nationalism and racialism in the west and opened the door to liberalism.

Nationalism and racialism is discredited because of liberal propaganda. The wars were a convenient way to accelerate anti nationalism. In fact I'm convinced the war was orchestrated as a structured breaking down of European nationalism.

People simply became fed up with all the wars and atrocities and gave into American globohomo liberalism.

If you oppose globohomo liberalism than why take a position against a leader that attempted to expel it from Europe while it was still in its development stages? Hitler didn't really want to kill Europeans, Americans or Slavs. He simply realized that you had to stand your ground.

You realize the argument you're making could be made against Putin right? Why are you supporting a 'tyrant' that's killing civilized whites in Ukraine?

Hitler's own scatter-brain contributed to the failure as instead of devoting Germany's limited resources to a few important projects, he went for a variety of failed wunderwaffe: Stealth Bombers, Maus tanks, railguns and so on.

Still better to dig in and fight than simply allow evil to take over your nation. I'm fine with you arguing that Hitler was a terrible general. That might be true. To then say Hitler is the most responsible for the destruction of western civilization? That's a specious conclusion.
