My view is that WWII was, militarily, an unavoidable consequence of how WWI ended.  Whoever was in charge of Germany in the late 1930s and early 1940s would have started the war and lost the war in much the same way Hitler did.  Whether German democracy would become a dictatorship in 1932 or 1942 is academic.  All the "good" things Hitler did, the minimum wage, the monetary stabilization, the reduced unemployment, almost any other party in charge of Germany could have also done at that time.

However, the genocide of Jews and Gypsies and Poles is not at all included in that inevitable war.  That's the part you can fully lay at Hitler's feet.
