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.
Of the 6 million Poles who died in WW2, 1/2 were Jews. About 1 in 5 Poles were killed during World War 2. A few hundred thousand civilians also died at the hands of the Soviets. Personally, I believe that WWII ended only when the last Soviet soldier left Poland.
Ok, if you are so smart, 12 million die in concentration camps, mostly located in Poland...who were other 6 million? As for Russian civilians, they do not die in concentration camps, I never say such, and they do not die fighting Germans...unless you consider example of 40,000 killed in Stalingrad on first day of air bombardment as "fighting". Most killed in mass murder or executions or bombardments or starved. Another 8 million Russian soldier die in battle or slave camps.
Wrong, Hitler had all measure to clear Poland of all Poles, as it was first wave for Liebensroumen...can't have colony land if no land available.
Do some serious reading:
Czechs & Slovaks were to be Germanized.
Poles, exterminated or sent off as Ouslander Arbieten (foreign worker: slave) in Germany.
Russians to be cleared out from all cities, mostly killed off the rest left in small villages as slave labor, agricultural.
Jews, exterminated.
Roma, exterminated
Roma were mostly killed off in Yugoslavia and Russia, where they have highest percentages (rest is in Romania but as allie, Romania did not let Hitler have his way). Those rolled up into general death toll.
