The Farhud, published in 2010 to broad praise, is Black's most recent Holocaust work, this excavating and chronicling the explosive international alliance between Nazis and Arabs. It came down to this: The Nazis needed oil. The Arabs wanted the Jews and British out of Palestine. The Mufti of Jerusalem forged a far-ranging alliance with Hitler resulting in the June 1941 Farhud, a Nazi-style pogrom in Baghdad that set the stage for the devastation and expulsion of the Iraqi Jews and ultimately almost a million Jews across the Arab world. The Farhud was the beginning of what became a broad Nazi-Arab alliance in the Holocaust. From Palestine to France, from concentration camps to the battlefield trenches, from sabotage units to three divisions of Waffen SS operating savagely in central Europe, tens of thousands of Arabs and Muslims fought shoulder to shoulder to advance Hitler's war against civilization and his determination to exterminate the Jews.
