The Cold War 1945-1991

US-Soviet rivalry, arms race, and proxy conflicts

Origins of the Cold War:

Wartime alliance (US, USSR, UK) broke down after WW2

Yalta and Potsdam Conferences (1945): disagreements over Germany, Eastern Europe

USSR set up communist buffer states in Eastern Europe

Churchill's Iron Curtain speech (1946): Europe divided

Truman Doctrine (1947): US would support free peoples resisting communist takeover

Marshall Plan (1947): US economic aid to rebuild Europe, prevent communism spreading

Key events:

Berlin Blockade (1948-49): USSR blocked Western supply routes; West used airlift

Korean War (1950-53): Proxy war; North (communist) vs South (US-backed)

Cuban Missile Crisis (1962): USSR placed missiles in Cuba; world's closest nuclear moment

Vietnam War (1955-75): Proxy war; US failed to prevent communist reunification

Berlin Wall (1961-1989): Built to stop East Germans fleeing

End of the Cold War:

Gorbachev's Glasnost (openness) and Perestroika (restructuring) weakened USSR

1989: Berlin Wall fell; communist regimes collapsed across Eastern Europe

1991: USSR dissolved

Key Points to Remember

1Truman Doctrine + Marshall Plan: US containment of communism
2Cuban Missile Crisis 1962: closest the world came to nuclear war
3Proxy wars: Korea, Vietnam — superpowers fought indirectly
4Gorbachev's reforms weakened USSR, leading to its 1991 collapse

Pakistan Example

US Involvement in Afghanistan — A Cold War Legacy

Pakistan was central to Cold War strategy. The CIA, through Pakistan's ISI, funded and armed the Afghan Mujahideen against the Soviet invasion (1979-89) — a classic Cold War proxy conflict. Pakistan received billions in US aid under Zia ul-Haq. The consequences — weapons flooding Pakistan, radicalisation, Afghan refugee crisis — shaped Pakistan's history. Understanding the Cold War is inseparable from understanding modern Pakistan's geopolitical situation.
