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

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.
