AP World History Cold War Overview | 2025 Study Guide

Step 3: Proxy Wars

The Cold War turned “hot” in proxy wars around the globe:

• Korean War (1950–53)
  • North (USSR/China-backed) vs South (U.S./UN-backed).
  • Ended in stalemate at 38th parallel.
• Vietnam War (1955–1975)
  • Ho Chi Minh led communist forces.
  • U.S. withdrawal → Communist victory in 1975.
• Afghanistan (1979–1989)
  • Soviet invasion met with U.S.-backed Afghan resistance.
  • Soviet failure → weakened USSR.

Proxy wars highlight the global reach of the Cold War.

Step 4: Nuclear Arms Race

• Mutually Assured Destruction (MAD) – Both sides stockpiled nukes.
• Cuban Missile Crisis (1962) – Closest to nuclear war.
• Nuclear Treaties – SALT, START tried to limit weapons.

Step 5: Space Race

• USSR launched Sputnik (1957) → first satellite.
• U.S. landed astronauts on the moon (1969).
• Space race symbolized technological + ideological competition.

Step 6: Cold War Leaders

• U.S. Presidents: Truman, Eisenhower, Kennedy, Nixon, Reagan.
• Soviet Leaders: Stalin, Khrushchev, Brezhnev, Gorbachev.

• Africa: Angola, Congo became Cold War battlegrounds.
• Middle East: U.S. supported Israel; USSR supported Arab states.

Connect Cold War to Decolonization movements.

Step 8: Cold War at Home

• McCarthyism in U.S. → fear of communism.
• Soviet Censorship → propaganda + repression.
• Cultural Competition → Olympics, film, music shaped public opinion.

Step 9: The End of the Cold War

• Détente (1970s) – Relaxed tensions.
• Reagan + Gorbachev (1980s) – Talks + reforms.
• Fall of Berlin Wall (1989) – Symbolic end.
• Collapse of USSR (1991) – Official end of Cold War.

Step 10: Impacts of the Cold War

• Political: Bipolar world order collapsed → U.S. emerged dominant.
• Economic: Arms spending strained USSR → economic collapse.
• Social: Spread of democracy movements in Eastern Europe.
• Globalization: End of Cold War accelerated global trade + cooperation.
