The Union began a power grab for supremacy in Eastern Europe. The West led by the United States of America began frantically to defend their interests from the threats posed by the communist expansion. This power tussle, in the history of warfare, is referred to as the Cold War, and resulted in most of Eastern Europe coming under the control of the communist Soviet Union. This paper examines the historical origin of the Cold War, highlighting the impact of the collapse of the Soviet Union on the global political economy. The study relied on secondary sources which include books, journal articles and internet materials. The study’s findings indicate that the collapse of the Soviet Union is not the end of the communist regime globally, as China benefited from the collapse in the sense that it has enabled China to modernize and integrate the economic models of the West. The paper concludes that the current Russian and Ukrainian war has linkage to the collapse of the Soviet Union and this is altering geopolitical dynamics across the world with immediate and remote effects on national economies. Consequently, the disintegration of the Soviet Union should teach global political leaders that political and economic reforms should not be dependent on external powers.
