How did FDR’s leadership decisions in World War II shape the post-war Cold War?As the post-war era approached after years of continuous fighting, there were many plans that were needed to be made for the future of Germany. The Allied nations claimed the victory of WWII and the United States held the status of the “protector of democracy”. The post-war era allowed for feuding countries to rebuild and seek peace among each for the future. The “Grand Alliance”, which included: United States, Great Britain, and the Soviet Union, were faced with the obligation to ensure that the post-war era was successful. Although the three countries were allied, they had some different interests at hand which led to many wavering opinions and constraints during the later conferences. To keep peace between the three countries, FDR, the president of the United States, made many decisions out of compromise. These decisions were meant to make the relations between the countries stronger, but created unwanted tensions and animosity between the countries. The cumulation of the wartime efforts had a direct correlation to the start of the Cold War era.The Tehran Conference was held in Iran during November and December of 1943. Roosevelt, Churchill, and Stalin engaged in discussions where the British and Americans finally committed to launching “Operation Overlord”, an invasion of northern France, to be executed by May of 1944. They also discussed the plan for post-war German reconstruction. But, the interests of the US and the Soviets were not the same. FDR wanted to persuade the Soviet Union to participate in the fight against Japan. Stalin, however, did not want to fight a war on the Pacific front. Eventually, he agreed to declare war on Japan under the conditions that it would be 90 days after Germany’s surrender and that the Soviet Union would receive the Japanese islands of Kurile, half of Sakhalin, and a few select Japanese ports. The plans were made, but they were not finalized till the Yalta conference, which was held almost two years later. Another important conference during this time period was the Cairo conference. This was an important factor in the decisions made for post-war. During the Cairo conference, Stalin refused to make an appearance. FDR, Churchill and China’s Chiang Kai-Shek focused on the topic of Korean independence from Japan. The three men agreed that “Japan will also be expelled from all other territories which she has taken by violence and greed. The aforesaid three great powers, mindful of the enslavement of the people of Korea, are determined that in due course Korea shall become free and independent” (Cairo Conference). The decisions were not concluded until the Potsdam conference in 1945. After German defeat, the Allied powers focused on the reconstruction of Europe and the battle with Japan. As a continuation of the policies agreed upon, in the Potsdam conference Korea was discussed in further detail. The Soviet Union now wanted to gain control of a part of the Northern region of Korea and rule with a communist government. FDR felt obligated to compromise and split Korea along the 38th parallel into North and South Korea. Americans were against the idea as it showed FDR’s inability to make a compromise without solely agreeing with Stalin. The split of Korea was unethical as it was thriving unified nation. After the Japanese defeat to the Soviet, Stalin wanted to gain complete control of Japan and turn it into a communist country. This battle against communism in Korea is known as the Korean War.During the Yalta Conference, there were many agreements made between Roosevelt, Churchill, and Soviet. After the war ended, the Soviet Union did not follow many of them which had a direct impact on the events that led to the start of the Cold War. The Cold War was a fight for world dominance between the United States of America and the Soviet Union. At Yalta, the leaders of the Allied nations met to plan the defeat of Hitler. Although they couldn’t agree on much, they all agreed to end the Nazi regime. Along with this, Germany would undergo many changes. Primarily, the split of the territory into the four occupation zones. As the war was coming to an end, there was an increase in the tension between the United States and the Soviet Union. Roosevelt and Churchill discussed with Stalin the conditions under which the Soviet Union would enter the war against Japan. Roosevelt let Stalin have his way but did as much as he could to secure Russian participation in the war against Japan. This had a direct impact in making the tension between the US and USSR greater. When the atomic bomb was dropped on Japan, the Soviets became more nervous and wanted to be ahead in the arms race. Along with this, the fate of Poland led to the mistrust and animosity among the different nations. Poland was supposed to be an anti-communist country with free elections but FDR let Soviet take control of Poland to ensure their participation in the invasion of Japan. This caused severe criticism towards FDR for “selling out” and it condemned Poland to Communism and Soviet control. Many of the outcomes of the Yalta Conference had a significant impact on the events that preceded the Cold War. The goal of the Potsdam Conference was to create a plan for rebuilding Europe and specifically the future of Germany. Both the Easterns and the Westerners had contradicting ideas on the best option to prevent another act of German aggression. The Potsdam Declaration states, “The German people would be given the opportunity to prepare for the eventual reconstruction of their life on a democratic and peaceful basis.” The Grand Alliance decide to divide Germany into four occupation zones, each under the temporary control of the Soviet, British, French and American. The general policies of the occupations were to demilitarize, decentralize and deindustrialize. The British and Americans had to accept the Oder-Neisse line as the new border between Poland and Germany. This caused a lot of discrepancies as the reparations of almost 3 million Germans were now into the Western zone. Stalin promised the the Polish provisional government would hold “free and unfettered elections as soon as possible on the basis of universal suffrage … in which all democratic and anti-Nazi parties shall have the right to take part,” and that the Western press shall enjoy “full freedom to report to the world upon developments in Poland.” Finally, Stalin ensures Soviet agreement to enter the Pacific War a few months after the German surrender. They also showed support to the declaration against Japan that stated: “prompt and utter destruction” if it did not surrender immediately and unconditionally. Truman, the new president of the US, was being sincere about his intentions with the declaration. After, Potsdam, the US detonated the world’s first atomic bomb.
