Although in hindsight the end of the Cold War was inevitable, almost no one saw it coming and there is little consensus over why it ended. A popular interpretation is that the Soviet Union was unable to compete in terms of power, especially in the area of high technology. Another interpretation gives primacy to the new ideas Gorbachev brought to the Kremlin and to the importance of leaders and domestic considerations. In this volume, prominent experts on Soviet affairs and the Cold War interrogate competing interpretations in the context of five ''turning points'' in the end of the Cold War. Relying on new information gathered from oral history interviews and archival research, the authors draw into doubt triumphal interpretations that rely on a single variable like the superior power of the United States and call attention to the importance of how multiple factors combined and were sequenced historically. The volume closes with chapters drawing lessons from the end of the Cold War for both policy making and theory building.
