After World War II, two super powers emerged; the United States of America and the Soviet Union. The competing ideologies led American leaders to pursue a policy of containment. The struggle that ensued between these two powerful nations is now referred to as the Cold War.
From the 1940s to 1990 tensions developed between two superpower nation. The united states and the Soviet Union had an era of confrontation and competition. In 1945 President Roosevelt, Winston Churchill and Joseph Stalin met at Yalta in order to plan a postwar world. They discussed issues over Poland and came to an agreement that soviets could set up a government within it. Stalin agreed that the government would include members of the prewar Polish government and that free elections would be help as soon as possible. In this a Declaration of Liberated Europe was formed. Soviets broke the Declaration which caused tensions to rise between the United States and Soviet Union. But before action could be taken, President Roosevelt died and Harry Truman took office. Truman met Stalin at Potsdam to decide what to do with Germany. The communist countries became satellite counties. The countries that separated communist and the non communist became known as the iron curtain. Along telegram was released by George Kennon, which explained his views on soviet goals which he thought Europe was experiencing hardships after the war and was in search for a way to secure there economy which the Soviets could provide. The U.S. should take advantage of this in order to keep the government within its borders.(2) After this in 1947 the Truman Doctrine was formed in which Truman asked for 400 million dollars to fight soviet aggression in Greece and Turkey. The goal of this was to free people who are resisting attempted subjugation by armed minorities of outside pressure. Greece was being terrorized by the soviets because they wanted to expand there government.
