The very dependence of the government-in-exile on the British was a source of much tension, and Peter in 1942 tried to involve the Soviet Union and the United States as counter-balances. In 1942 Peter made a diplomatic visit to America and Canada, where he met American President Franklin D. Roosevelt and Canadian Prime Minister William Lyon Mackenzie King. The whirlwind tour was unsuccessful in securing Allied support for the exiled Yugoslav monarchist cause. Roosevelt and Churchill had already engaged the support of the Communist Yugoslav Government in the Allied effort to defeat Nazi Germany, with a view to ending the Second World War. Roosevelt made Yugoslavia eligible for Lend-Lease aid during Peter's visit, but given the small size of the Yugoslav forces in exile, this was not of much assistance.
