Actually, it was the Palestinians who were working with Hitler. The Mufti of Jerrusalem was a genocidal Nazi who headed death squads in the Balkans and who had been promised the extermination of Midddle east Jewry after the Nazis finished off the European Jews. Within the Palestinian mandate, he ruthlessly persecuted both Jews (who were terrorized by the muslims long before the establishment of the Irgun) and any Arabs who opposed his genocidal ambitions.

The Nazi connection is well established, as is the relationship between the Nazi ideology and Hamas/Hizb'Allah and their ilk.
