(over Zionist immigration) led to the 1929 Palestine riots. In these religious-nationalist riots Jews were massacred in Hebron and the survivors forced to leave the town. Devastation also took place in Safed and Jerusalem. In 1936 an Arab uprising occurred, which lasted for three years. The Supreme Muslim Council in Palestine, led by the Mufti, organized the revolt. During the revolt the Mufti was forced to flee to Iraq, where he was involved in a pro-Nazi coup during which the Jewish areas of Baghdad were subjected to a pogrom. In 1939 he rejected as insufficient the British White Paper, which imposed restrictions on Jewish immigration and land acquisition by Jews. After the British reoccupied Iraq the Mufti joined the Nazis. He worked with Himmler and aided the SS his main role was broadcasting propaganda and recruiting Muslims, primarily for the Waffen SS in Bosnia. In 1948 the Mufti returned to Egypt. He was involved in the short-lived All-Palestine Government sponsored by Egypt but was sidelined by most of the Arab countries.

Following Roosevelt's death, the Truman administration publicly adhered to the policy announced in the letter in an official statement released on October 18, 1945. Growing conflict with the Palestinian Arab population One issue fatally divided Arab and Jew in Palestine: immigration. Jews would not compromise over immigration, which they needed as a means of escaping European persecution and which was a core doctrine of Zionism. The Arabs for their part could not compromise on immigration because to do so would effectively end their majority in Palestine. As time went on the conflict between the two communities became increasingly bitter. British immigration restrictions British support for Zionism was always controversial and the issue was periodically debated in Parliament. Churchill also restricted Jewish migration to an annual quota decided by the British. Certificates allowing migration were distributed by the Jewish Agency. Jews with 1000 Pounds in
