Under treaties of 1944 and 1945 the USSR permitted the departure of hundreds of thousands of Polish citizens, many of them Jews, who had found themselves on Soviet territory after the annexation of eastern Poland or who had fled there subsequently. In addition to relieving the USSR of a potentially unreliable group and increasing the population of its future satellite state, another consideration in permitting a large-scale emigration may have been Stalin’s desire to gain sympathy in the West during negotiations over Poland’s future borders, and thus to neutralize one basis for the hostility promoted by the London-based Polish government-in-exile. Stalin’s related willingness for Poland’s new Communist government to permit the emigration of Jews to Palestine likely manifested the dictator’s interest in creating difficulties for the British Empire and gaining influence in a possible future Jewish state.
