The collapse of the Soviet Union in 1991 remains one of the most significant—and controversial—events of the last fifty years. The Soviet Union's breakup has been attributed to many different factors, from the costly war in Afghanistan to the Cold War arms race with the United States. Through a narrative-driven pro/con format—supported by relevant facts, quotes, and anecdotes—this book examines controversial issues stemming from historic events. Topics include: Was the Soviet Invasion of Afghanistan a Key Factor in the Soviet Union's Collapse? Did the Arms Race Cause the Soviet Union's Collapse? Did Gorbachev's Reforms Make the Soviet Union's Collapse Inevitable? Is Today's Russia More or Less of a Threat than the Soviet Union Was?
