That is true, but least one forget the 6 million Poles who die in Concentration camps, 22 million Russian civilians, 1 million yugoslavs, 1 million Greeks, 1 million Italians (after it switch sides), 2-4 million French and few million Germans who less then agree with Hitler.
Six million Poles and 22 million Russians did NOT die in concentration camps. Rather, most died fighting Nazism. They, too, are victims of Hitler and the Nazis and should be remembered and honored. However, Hitler never had a plan to exterminate all Poles and Russians as he did Jews and Roma (gypsies). I noticed you didn't mention the 3 million Roma dead. By percentage of the population they lost more than the Jewish people did.
