I think if Hitler didn’t break the Molotov Ribbentrop pact, he wouldn’t be remembered as the devil he is now. Without USSR on the allies side, it would be a lot harder to defeat Germans. If the Nazi Regime survived, the successors of Hitler would get closer to USSR most likely and embrace the socialist nature of the Nazi party more than ever. Germany could even become another country in the eastern socialist Bloc.
Even the Soviets would remember the Nazis as socialist heros who unified western Europe and rebelled against the Angelo Saxon capitalism.
If the Nazis lost they would also remember them and Hitler as martyrs. People around the world would have Hitler’s portrait on their wall and clothes just like Che Guevara. Just a revolutionary socialist rebel who fought against capitalism until death.
