Reality on the ground is much different. While the Soviets did bear the brunt of the Nazi onslaught, what is often overlooked is their own culpability in the war (invading and splitting Poland in partnership with the Nazis, &c) and their evil annexations of peoples and countries that were nearby as part of their own power-grab. In other words, part of the reason they were in the war in the first place is because they joined the Nazis in effectively kicking it off, at least in Europe.
Soviet apologists also tend to forget that the United States and other anglo powers* simultaneously fought the Nazis in the west, took down the Japanese, invaded and liberated Italy, the Philippines, and more, fought and won in North Africa, and did all of this while providing the Soviets with the equipment they needed to stay in the war. Nevermind staging additional campaigns and operations, such as those in China to aid them against Japanese occupation.
* I don't intend to suggest that it was only the United States, United Kingdom, Australia, and Canada that fought the good fight because we undoubtedly received heroic contributions from numerous allies and friends during the war.
Nice story. One problem though: they eagerly joined Nazis in exterminating Jews. The ideology of nationalists aligned quite well, be it German Nazis, Baltic states, Hungarians or Western Ukrainians.
Russians are killing their future for sure.
