The bolded part is pure apologism and revisionism. Like I said to vendur, no aspect of communism had the concepts of Lebensraum, exterminating of Jews, subjugation of Slavs, subjugation of non-Germans, supreme racial superiority, etc. Communism allowed the Soviet Union to become a world power - which is miraculous considering that Tsarist Russia had been constantly humiliated on the international stage - without starting the largest and most terrible war in history.
Communism is simply a failure in practice based on Marx's false perceptions of reality. Nazism is a corrupt ideology in an of itself. That's the difference between them.
No, it isn't apologism or revisionism at all. First off, if we are to be apologists, all nations that took part in the war have a lot to apologize for because all nations, with all the major political players, industrialists, bankers and other influential people were in the wrong.
Secondly. Tsarist Russia was never humilliated on the international stage, at all. It had one of the most respected houses ruling it, one of the largest armies, the most land, a history of victories in war, and much more. It was, furthermore, a center of knowledge and culture. Most of the great Russian writers were born before communism took over. Most of the great composers and men of culture and integrity were in the era before communism took over. Communism destroyed Russia and the Russian people, along with all east European nations and people. Yes, tsarist Russia wasn't an industrialized nation as the UK was, or as germany was, at the start of WW1. But it is much harder to industrialize a nation as huge as Russia, not to mention that Tsarist Russia stretched further than the USSR did, occupying much of Poland, Ukraine all the way to the Nistor river.
And make no mistake, you can't distance yourself from communism. "Communism is simply a failure in practice based on Marx's false perceptions of reality" this is complete and utter non-sense. The way communism was implemented, especially during the stalinist era, was the best possible version that communism could ever be implemented as. The closest to the perfect ideal of communism. And we all know what that resulted in. Over 15mil in gulags, about 20mil died in the Holodomor, millions deported from their homelands for no good reason. Millions more shot and killed to instill terror. Nothing beats the commies in the human suffering department.
And of course it had a superiority doctrine. All nations during WW2 had a superiority doctrine... except the French maybe... and the British had mostly a dehumanization doctrine to keep their men fighting, but the USSR, the nazis, the Americans, the Japs, all had superiority doctrines against their enemies, dehumanizing them as much as possible. They were no better than the nazis in that regard.None was better. There were no "good guys" or "bad guys". If we look to the world according to how these nations saw each other, collectively, we would be looking at a world of inferior human beings.
