People don't realize that the source for much of what was brought up at Nuremburg was the Soviets, who were famous for secrecy and lying. This information was presumed accurate, per the terms of the trials. Essentially, history books are willfully full of whatever the KGB wanted you to think at the time. This isn't even pro-Nazi/anti-Nazi. It's anti Communist. You know, whatever the Germans did, the Soviets inflicted in triplicate on E. Europe after they took over and established puppet regimes. And the KGB is still in charge of Russia (tho presumably a different generation than the WW2 one). So you can follow that thread without being a neo-Nazi.

And look who does history think were the worst guys: The Soviets or the Nazis? Essentially the Soviets made shit up to cover their own atrocities in the war, and it worked so well they decided to keep harping on it as they continued to kill in Europe.
