In 1938 he set up an information office in Damascus which received some funds from the local German and Italian Consulates. Meanwhile, within Palestine the British and the Jewish Agency were funding 'Peace Bands' to combat the rebel's successes. During this period his proposals included pledges of equal rights for Jews in any future Palestine. In 1939 he led the Arab delegation to the London Conference following the failure of which the British Government announced its plans for the future of Palestine in a White Paper which included plans for a limit to Jewish immigration. By this time Jamal had become far more outspoken: “The Jews have turned Palestine into hell.” The outbreak of the Second World War ended all diplomatic activity related to Palestine and the British proposals were quietly shelved.
