Introduction: Understanding the Cold War
The Cold War (1945-1991) was a period of geopolitical tension between the United States and its Western allies against the Soviet Union and the Eastern Bloc. Rather than direct military conflict between the superpowers, the era was characterized by proxy wars, ideological competition, nuclear arms races, and espionage. This cheat sheet provides a comprehensive overview of key events that defined this pivotal period in world history.
