Towards the end of World War II, Stalin was already putting in place measures for a communist takeover. On the other hand, Churchill sought the survival of the British Empire and the territory’s supremacy. The United States under Roosevelt and later Truman was focused on economic supremacy and the establishment of global institutions to foster world peace. Supremacy struggles between the three strong groups led to conflicts emanating from underhanded deals among the powers.
After the war, Stalin strengthened the Soviet Union’s foothold in Eastern and Central Europe. The United States and Western powers secured Western Europe. The United States later bombed Hiroshima and Nagasaki, but Truman prevented Soviet forays in Japan. The situation deteriorated when the Stalin and Truman administrations prepared for a supremacy war due to what seemed to be an expansionist agenda. In addition, Churchill’s “Iron Curtain” speech supported an Anglo-American coalition to face the Soviets. Grandstanding by the different leaders eventually led to the Cold War.
Stalin was stronger at the outset with control of Eastern and Central Europe. However, the Containment policy and the Truman Doctrine eventually forced an end to the war.
