Nonsense.
There was not a single "death camp" in Germany or any area the US troops got to.
All the death camps were tiny and totally obliterated before the Russians got to them, since they were almost all in Poland.
My father liberated a concentration camp at Nordhausen. The shit he saw there haunted him for the rest of his life.
I'm the first one to criticize the Zionists for their bad behavior, but we should never minimize what happened during the war.
