"As Churchill and Roosevelt were overselling Yalta to the West, the agreements made there broke down in Eastern Europe during the month after the conference. The Soviets dragged their feet on repatriating prisoners of war. They did not send representatives to London to start up the new Control Commission for Germany. In Romania they forced the king to appoint a new government dominated by communists. In Poland they allowed the communist provisional government to veto candidates for its own “reconstruction” and to exclude Western observers, while potential rivals in Poland were butchered or sent to the camps. Stalin also said that Molotov was too busy to come to San Francisco and that the Soviet delegation to the UN founding conference would be led by Andrei Gromyko, then a midlevel diplomat. This was taken not only as a blatant snub but also as a real threat to the whole structure of postwar cooperation."
