Just as an aside I saw “Downfall” a few years ago Germany's first movie on the last days of Hitler. It shows how insane things were in Berlin, like a sci-fi movie.
Downfall is in the top ten of all time great movies, period.
I am really not sure that is true. I read that ethnic Germans, in what was Poland, were being murdered horrifically by Polish people prior to the war. Hitler, being unbalanced, heard of it and flew into a rage. Also, I don't think Germany murdered it citizens (unless they were Jewish). Russia murdered its citizens (Georgians and others).
I think the reason Nazi Germany got the bad press is they lost. Others were just as bad, IMHO. It was a European thing, something we Americans cannot truly understand.
