By March 1945, it had become clear that Stalin had no intention of keeping his promises regarding political freedom in Poland. Instead, Soviet troops helped break any resistance to the provisional government based in Lublin, Poland. When elections finally took place in 1947, they consolidated Poland as one of the first Soviet satellite states in Eastern Europe. The Yugoslav partisans received the full support of the Allies, and The Allied support to the Yugoslav Cheniks was halted because they were believed to be working with the occupying Germans instead of fighting them. Communist supporters under Tito took power in Yugoslavia when the Germans withdrew from the Balkans. Roosevelt devised a plan to divide the country into several autonomous regions, with the main industrial and commercial centers under international control. Churchill felt that this was impractical and preferred instead a kind of north-south divide that weakened « preusism » at the expense of what he saw as the less militaristic and aggressive regions of southern Germany. Stalin saw things differently and said that all Germans were belligerent and infidian by propensity and that their country had to be permanently fragmented, with no possibility of reunification. During the conference, the three heads of state and government coordinated their military strategy against Germany and Japan and made a series of important post-war decisions. The conference`s most notable achievements focused on the next phases of the war against the Axis powers in Europe and Asia. Roosevelt, Churchill and Stalin had discussions about the conditions under which the British and Americans finally committed to launchIng Operation Overlord, an invasion of northern France that was to take place until May 1944.
The Soviets, who had long pushed the Allies to open a second front, declared themselves ready to launch a new large-scale offensive on the Eastern Front, which would divert German troops from the Allied campaign in northern France. Stalin also agreed on the principle that the Soviet Union would declare war on Japan after an Allies` victory over Germany. In exchange for a Soviet declaration of war in Japan, Roosevelt recognized Stalin`s claims to the Kuril Islands and the southern half of Sachaline, as well as access to the ice-free ports of Dairen (Dalian) and Port Arthur (Lashun Port) on the Liaodong Peninsula in northern China. However, the exact details of this agreement were not finalized until the 1945 Yalta Conference. When the German-Soviet war broke out in June 1941, Churchill offered aid to the Soviets and an agreement was signed on July 12, 1941.  However, in a radio broadcast in which he announced the alliance with the USSR, Churchill reminded listeners that this alliance would not change his attitude against communism.  Delegations had travelled between London and Moscow to organize the implementation of this support, and when the United States joined the war in December 1941, delegations also met in Washington. A committee of team leaders was set up to coordinate British and American operations and their support for the Soviet Union. The consequences of a world war, the absence of a single allied strategy and the complexity of the allocation of resources between Europe and Asia have not yet been elucidated and have quickly led to mutual distrust between the Western Allies and the Soviet Union.  This was the opening of a second front to relieve German pressure on the Soviet Red Army on the Eastern Front, the issue of mutual assistance (where Britain and the Soviet Union sought both loans and material support to the United States and where there were tensions between the United States and Great Britain, with Washington not having the desire to support the British Empire in the event of an Allies` victory).  Neither the United States nor Great Britain were prepared to give Stalin carte blanche in Eastern Europe, and finally there was no common policy on how to treat Germany after Hitler.
