Towards the close of 1944, it had been decided that there would be a need to divide Germany into four occupied zones run by the Soviet Union, French, British and the US forces after the unconditional surrender of Nazi Germany.
In February, between 4th and 11th, 1945 {more here}, a World War II meeting was called and held by the three chief leaders, Soviet Union’s Premier Joseph Stalin, United Kingdom’s Prime Minister Winston Churchill and United States’ President Franklin D. Roosevelt in a Russian resort town. The three met at Yalta Crimea to plan on abolishing and confiscating the German military industry.
The Yalta Discussion

The meetings focused on four key topics. They discussed the eventual surrender, the voting procedures with the United Nations Security Council, conditions in which Stalin would get into the war against the governing of Manchuria following the Japanese surrender and the governing of Poland and Germany post-war.
The three knew that victory in Europe was inevitable but not entirely convinced about the end of the pacific war. Stalin, Roosevelt and Churchill agreed to include France in Germany’s governing and allow Germany to assume some power for reparations.
The negotiations followed the declaration for the provision of the inclusion of communists in Poland’s post-war national government. Regarding the UN, they all agreed to settle on an American plan in the Security Council voting. All the permanent members were then required to hold a veto on the decisions before the council.
The Yalta Reactions
After they had all come to an agreement, the discussion received a celebratory reaction. Americans viewed the decision as enough proof to carry the Soviet wartime cooperation of the US into the postwar period. However, the celebration was not to last.

In April 12, 1945, after the death of Franklin Roosevelt, Harry S. Truman was voted the US third president. This led to an almost immediate clash of the new administration with the Soviets following their influence on the United Nations and the eastern Europe region. The lack of cooperation caused Americans to begin criticising the Yalta meetings and negotiations.
The Yalta conference is arguably the most famous, a meeting held by the three heads of the Allied powers after World War II to create stability and peace in Europe. The implications of the conference are still felt decades afterwards, marking the final stage of the war and Europe formation.
