What's more likely to happen in 30-40 years is what you're trying to do - make people forget that there were two equally evil empires - Nazis and Soviets. You want people to remember only Nazis.

The Soviets killed millions - there is no way to deny it. Holodomor alone resulted in 3-5 mln deaths. At least one million were murdered in Russia alone. In total, up to 60 mln people are estimated to have died at the hands of the Soviets. Millions more were forced out of their homes, raped and maimed.

There is only one difference between Germans and Japanese on the one hand and Russians on the other. Germans and Japanese admitted to these atrocities and apologized for them. Since the end of WW2, they have not attacked anyone else.

Russians, on the other hand, are still trying to whitewash the crimes committed by the Soviets, and they keep invading other countries. We can only hope they will either grow up and join the civilized world this century or the Russian Federation collapses.
