Well. . DUH. . .
1. The Palestinians had no part in the Holocaust. . .except maybe cheering it on from afar. . .
2. Why must EVERYTHING revolve around the Palestinians ??? A nation that does not, and never did exist other than a British Protectorate, which does not, and never did have a distinctive government, culture, or language, and primarily exists today because other Arab nations have refused to assimilate these "refugees" (who left of their own accord to make the supposed conquest of Israel easier. . .).
There were nazi death camps in which 800,000 Christians and Jews died. I cannot remember the totals but is was something like 20,000 Jews and the rest were Christians.
Actually, the leader of the Palestinians at the time, Yasser Arafat's uncle Haj Amin al-Husseini, spent much of the war in Berlin. He and his people in Palestine wanted to bring the "final solution" home.
So, yes, some Palestinian Arabs were involved on the Nazi's side.
