When the alliance defeated Germany, the power of the Soviet Union remained even stronger than ever. However, the country drifted from the alliance with Western countries slowly due to several issues that caused differences between the Soviet Union and Western countries. The success of the alliance between the Soviet Union, Britain and US strengthened the Soviet Union economically and politically. Its military also became strong.
As a result of this immense rise of the Soviet Union after World War II, the union joined its western allies in postwar reconstruction. However, conflicts between the Soviet Union and its western allies made the reconstruction difficult. Specifically, the Soviet Union and the USA became very strong and strongly opposed each other in fundamental economic and political issues. This conflict resulted in the Cold War, in which the USA and the Soviet Union played a primary role in evoking.
USA’s power started since World War I when the country joined other countries of Western Europe to fight the Germans. The US got economic and political support from European countries such as Britain and France during World War I. This support helped the US to build a very strong nation with a very strong military base. This powerful nation then joined World War II with Russia and Britain to fight against the Germans who had caused the problem in the Atlantic region and affected the trade between US and Western countries.
The US military was cut into half its prewar size as a result of World War II. Russia’s Stalin had predicted that the US would be given in to domestic pressure for demilitarization and cut down on its military expenditure. As a result, they would encounter overproduction; hence causing another great depression.
