Palestine or the areas of the emergent Jewish State; and the Yishuv did not enter the war with a plan or policy of expulsion. Nor was the pre-war ‘transfer’ thinking ever translated, in the course of the war, into an agreed, systematic policy of expulsion." Other authors, including Palestinian writers and Israeli New Historians, have also described this attitude as a prevalent notion in Zionist thinking and as a major factor in the exodus. Peel Commission's plan and Yishuv's reaction The idea of population transfer was briefly placed on the Mandate's political agenda in 1937 by the Peel Commission. The commission recommended that Britain should withdraw from Palestine and that the land be partitioned between Jews and Arabs. It called for a "transfer of land and an exchange of population", including the removal of 250,000 Palestinian Arabs from what would become the Jewish state, along the lines of the mutual population exchange between the Turkish and Greek populations after the Greco-Turkish War of 1922. According to the plan "in the last resort" the transfer of Arabs from the Jewish part would be compulsory. The transfer would be voluntary in as far as Arab leaders were required to agree with it, but after that it would be almost inevitable that it would have to be forced upon the population. According to Nur Masalha, heavy Zionist lobbying had been necessary for the Peel commission to propose this "in the last resort" compulsory transfer. Shertok, Weizmann and Ben-Gurion had travelled to London to talk it over, not only with members of the commission, but also with numerous politicians and officials whom the commission would be likely to consult. This solution was embraced by Zionist leaders. Masalha also says that Ben-Gurion saw partition only as an intermediate stage in the establishment of Israel, before the Jewish state could expand to all of Palestine using force. According to Morris, Arab leaders, such as Emir Abdullah of Transjordan and Nuri as-Said of Iraq, supported the idea of a population transfer. However, while Ben-Gurion was in favor of the Peel plan, he and other Zionist leaders considered it important that it be publicized as a British plan and not a Zionist plan. To this end, Morris quotes Moshe Sharett, director of the Jewish Agency's Political Department, who said (during a meeting of the Jewish Agency Executive (JAE) on 7 May 1944) to consider the British Labour Party
