As a side note....
I don't understand by what standards western nations came to an unanimous conclusion that somehow the Nazi regime was by far more immoral than any of the Communist regimes.
Yes, Nazism was evil. No doubts about that in my mind. They persecuted not only Jews but many other minorities. I don't have the figures, but for the sake of the argument, let's say they went after 10-20% of the population. Absolutely horrible. But how is that worse than communists that often persecuted at least 90% of their population?
