Final answer:
The collapse of the Soviet Union was influenced by Gorbachev's nonintervention in communist bloc uprisings and his willingness to make changes.
Step-by-step explanation:
The collapse of the Soviet Union was influenced by several factors, but two key factors were:
- Gorbachev's stance of nonintervention in communist bloc uprisings: Unlike the violent response of the Soviet Union in the past, Gorbachev allowed democratic revolutions to take place in Eastern Europe in 1989. This led to the discrediting of communist leaders and the establishment of parliamentary democracies.
- The leader's willingness to make changes: Gorbachev implemented reforms such as perestroika (economic restructuring) and glasnost (political openness) in an effort to strengthen the Soviet Union. However, these efforts ultimately contributed to the disintegration of the Soviet Union.
