The Mufti had nothing to do with the rise of Hitler.Congress supported Israel when they discovered Hitler had ordered the genocidal murder of 6,000,000 German Jewish citizens with the help of the Mufti of Jerusalem, using WWII as their cover. Most US Congress members do not support those who harm American Allies.
How do you feel about the Lavon Affair or the bombing of the King David hotel or the attack on the USS Liberty? How about the betrayal of Reagan and the Sabra Shatilla massacre? The PLO had already left for Tunisia.
