Introduction The period 1945-1990, referred to as the cold world war, arose because of national conflicting interests between the United States and the Soviet Union over the future of Europe. Europe fought their final battles in the World War II, which left their economies in tatters with Eastern Europe under communist control. The cold war between United States and Soviet Union took the dimension of economic pressure, discriminating help, half-truths and assassinations. Shallow military operations intensified in bid to avoid a nuclear war. With the end of the Second World War, the Soviet Union swore against a repeat German invasion. Additionally, the Soviet Union’s intention was ensuring that the non-communist nations in Eastern Europe crashed. This is when the United States concern over Europe grew and thus increased her involvement. Economic Intervention Europe had embraced industrial revolution. There was high industrial development across the region prior to the World War II. The war brought the economy of Europe into waste, with many of its industries destroyed. During the period of 1945-1990, many of the countries in Eastern Europe fell into communist hands of the USSR. United States came in seeking to help save the European economy under the Marshall Plan. It aided the western part of Europe militarily and helped in rebuilding the economy. By the 1980’s the communist nations were rapidly falling while the economies of Western European countries were increasingly gaining power. This is highly attributable to the support of the USA. With the help of America, many of the western nations moved to link together through economic integration. They formed the European Union that increased trade among them through shared infrastructure. They agreed on a common currency (the euro) and made trade agreements that set their economies on the path to recovery. Britain had been weakened by the Second World War hence it could no longer support countries in Europe like Greece and Turkey. Therefore, Britain sought the intervention of the United States. United States was strongly opposed to communism and to avoid European economies from falling in the hands of the Soviet Union they provided financial aid. They also played a major role in stabilizing the civil wars at the time. America’s intervention through the Truman Doctrine saved the nations from soviet communism. In effect, America saved Europe from foreign policy failures and military humiliation. America believed that once a country falls into communism it would also weaken the neighbors as there would be minimum interaction because of diverging trade systems. Their support was evident when the Soviet Union pressured Turkey over the Dardanelles Strait concessions that would have allowed invasion from the west, through enunciation of the Truman Policy (Archie 2011). When Stalin attempted to blockade West Berlin in a bid to take control and convert the Market System to a Communist System, USA aided Berlin with supplies and food (Berlin Airlift). This enabled Europe to maintain control of its cities from the Soviet Union. Were it not for the vast amount of aid America gave to Europe, European economies would have fallen further with the Soviet Union invasion during the cold war (Archie 2011). Effect of United States Political Policies After the Second World War, United States and the Soviet Union were the only remaining super powers. During this period a greater part of Eastern Europe was in the hands of the communist, the boundaries of Europ
