Review Questions

  • How did Gorbachev's policies contribute to the process of Soviet dissolution?
    • Gorbachev's policies of perestroika and glasnost played pivotal roles in the Soviet dissolution by promoting economic restructuring and greater openness in government. These reforms weakened the grip of the Communist Party on power and allowed for public discourse about dissatisfaction with the regime. As citizens began to voice their demands for reform, national movements gained momentum across various republics, ultimately leading to declarations of independence and the collapse of Soviet authority.
  • Evaluate the significance of the failed coup attempt in August 1991 on the future of the Soviet Union.
    • The failed coup attempt against Gorbachev in August 1991 was a crucial turning point that significantly hastened the process of Soviet dissolution. It showcased the weakening control of hardliners within the Communist Party who sought to maintain traditional Soviet authority. The coup's failure not only bolstered Gorbachev's rivals, such as Boris Yeltsin, but also emboldened various republics to declare independence from Moscow. This event catalyzed rapid political changes that culminated in the formal disintegration of the Soviet Union just months later.
  • Discuss how the dissolution of the Soviet Union reshaped international relations in the post-Cold War era.
    • The dissolution of the Soviet Union fundamentally reshaped international relations by ending decades of Cold War rivalry between two superpowers: the U.S. and USSR. With the Soviet Union's collapse, a new unipolar world emerged, where U.S. dominance became more pronounced as it led efforts toward globalization and expansion of democratic ideals. The dissolution also led to new geopolitical challenges as newly independent states navigated their identities and relations with both Russia and Western nations, introducing complexities that continue to influence global politics today.
