1991, International Affairs
The sudden and surprising end of the Cold War in the late 1980s closed an epoch in modern history. As a superpower confrontation, ideological contest, arms race, and competition for geopolitical influence, the Cold War dominated international relations for forty-five years . It shaped the foreign policies of the United States and the Soviet Union and deeply affected their societies and their political, economic, and military institutions. By justifying the projection of US power and influence all over the world, the Cold War facilitated the assertion of global leadership by the United States. By providing Soviet leaders with an external enemy to justify their repressive internal regime and external empire, it helped perpetuate the grip of the Communist Party on power. In both countries, the Cold War compelled ongoing mobilization for war, locking the Soviet Union even tighter into the bifurcated command economy that led to its downfall, while pushing the United States toward a stronger central state and hybrid economic management that produced progress by reducing social inequalities and creating a "social bargain" within reformed capitalism. In addition to its impact on the superpowers, the Cold War caused and sustained the division of Europe, and within Europe, Germany. It also facilitated the reconstruction and reintegration of Germany, Italy, and Japan into the international system following their defeat in World War II. The impact of the Cold War was especially great in the third world, where it overlapped and interacted with longer-term trends like decolonization and sweeping social and economic changes. The Cold War led to the division of Vietnam and Korea and to costly wars in both nations, and it exacerbated conflicts throughout the third world. During crises, the Cold War's nuclear arsenals threatened the end of human civilization. In short, the Cold War was at the center of world politics in the second half of the twentieth century. Debates about the end of the Cold War are inextricably bound up with assumptions about the nature of the Cold War. As Richard Ned Lebow (2000, p. 208) has noted, "the debate about the end of the Cold War is at its core a controversy about the validity of the principles that shaped Western understanding of the Soviet Union and its foreign policy." Defenders of US policies blame the Cold War on an expansionist and ideologically motivated Soviet Union and argue that victory in the Cold War vindicates US policies during the conflict. In contrast, more critical scholars argue that US policies and actions played an important role in starting and sustaining the Cold War and that less confrontational US policies could have led to the end of the Cold War sooner and at a lower cost.
