Review Questions
What were the primary causes of World War II and how did they contribute to the outbreak of the conflict?
The primary causes of World War II included unresolved issues from World War I, such as the harsh terms of the Treaty of Versailles, economic instability during the Great Depression, and aggressive expansionist policies from totalitarian regimes like Nazi Germany and Imperial Japan. These factors created a volatile political climate that led to invasions and ultimately triggered the war when Germany invaded Poland in 1939.
How did World War II influence global power dynamics and lead to the emergence of the Cold War?
World War II significantly altered global power dynamics as it resulted in the decline of European colonial empires and established the United States and the Soviet Union as superpowers. Their differing ideologies—capitalism versus communism—created tensions that surfaced in various conflicts around the world. The competition for influence and control over post-war territories marked the beginning of the Cold War era.
