Cold War (1947–1991): Origins, Key Episodes and Decolonisation
The Cold War (1947–1991) was the ideological and geopolitical rivalry between the USA and USSR that defined global politics for nearly half a century — fought through proxy wars, arms races, space competition and the constant threat of nuclear annihilation. India's Non-Alignment was a direct response to this bipolar world.
1. Origins of the Cold War (1945–47)
Why they fell out: The USA and USSR had cooperated against Hitler but had fundamentally incompatible visions for the post-war world:
- USA: Liberal capitalism, free markets, democratic elections, open trade, dollar hegemony through the Bretton Woods system.
- USSR: Communist one-party states, command economies, Soviet-aligned governments in Eastern Europe as a security buffer, world communist revolution.
Key moments of rupture:
- Yalta Conference (February 1945): Roosevelt, Churchill, Stalin agreed on post-war arrangements; Stalin promised free elections in Eastern Europe — a promise immediately broken.
- Truman Doctrine (March 1947): President Truman asked Congress for $400 million to support Greece and Turkey against communist insurgency; declared USA would "support free peoples who are resisting subjugation by armed minorities or by outside pressures." This was containment.
- Marshall Plan (1947): $13 billion to rebuild Western Europe — partly economic recovery, partly to make communism unattractive to war-devastated populations. USSR refused and prevented Eastern European countries from accepting.
- Berlin Blockade (1948–49): USSR blockaded West Berlin; USA and allies ran the Berlin Airlift for 11 months; blockade failed.
- NATO formed (April 1949): North Atlantic Treaty Organisation — mutual defence pact among Western nations.
- Soviet atomic bomb (August 1949): Arms race began in earnest.
2. Cold War Concepts
| Concept | Meaning |
|---|---|
| Containment | US policy (George Kennan) — prevent Soviet expansion beyond existing borders |
| Deterrence | Threat of nuclear retaliation to prevent attack (MAD — Mutually Assured Destruction) |
| Proxy war | Superpower conflict fought through client states (Korea, Vietnam, Afghanistan, Angola) |
| Iron Curtain | Churchill's phrase (1946) for the division between democratic West and communist East Europe |
| Domino Theory | US belief that if one country fell to communism, neighbours would follow |
| Détente | Relaxation of Cold War tensions (1969–79) through US-Soviet diplomacy |
3. Key Episodes
Korean War (1950–53)
North Korea (Soviet-backed) invaded South Korea (June 1950). The UN (in USSR's absence) authorised a multinational force led by the USA (Gen. MacArthur). China intervened when UN forces approached the Yalu River. Armistice (July 1953) restored the 38th Parallel as the boundary. India's role: V.K. Krishna Menon negotiated the POW formula at the UN; India headed the Neutral Nations Repatriation Commission.
Cuban Missile Crisis (1962)
USSR placed nuclear missiles in Cuba (discovered by US U-2 spy planes, October 1962). 13 days of the most dangerous nuclear confrontation in history — JFK's "eyeball to eyeball" with Khrushchev. Resolved: USSR removed missiles; USA pledged not to invade Cuba and secretly removed Jupiter missiles from Turkey. Lesson: direct communication needed — Moscow-Washington Hotline established 1963.
Vietnam War (1955–75)
Communist North Vietnam (Ho Chi Minh) vs. US-backed South Vietnam. USA escalated massively (1965–73): 58,000 US troops killed; 1–3 million Vietnamese civilians killed. Anti-war movement in USA transformed US politics. The Tet Offensive (1968) shattered US public confidence. USA withdrew 1973; South Vietnam fell 1975.
Soviet War in Afghanistan (1979–89)
USSR invaded Afghanistan to prop up communist government. USA backed the Mujahideen (Islamic fighters) with weapons and money (Operation Cyclone — via Pakistan's ISI). Ten years later, USSR withdrew — the USSR's "Vietnam." Many Mujahideen later became the Taliban and Al-Qaeda.
4. End of the Cold War (1989–91)
Gorbachev's reforms:
- Glasnost (openness): Political liberalisation, free press.
- Perestroika (restructuring): Economic liberalisation.
- Sinatra Doctrine: Eastern European countries could choose their own path.
Fall of Berlin Wall (9 November 1989): The defining image of the Cold War's end; Germans dismantled the wall that had divided Berlin since 1961.
Dissolution of the USSR (25 December 1991): 15 Soviet republics became independent. Russia emerged as the successor state. The Cold War ended.
5. Cold War and India
India's relationship with the Cold War was shaped by Non-Alignment but was not equidistant:
- After the 1962 war with China, India leaned toward the Soviet Union.
- Indo-Soviet Treaty of Peace, Friendship and Cooperation (1971): Signed just before the Bangladesh war — India needed protection against potential US intervention (Nixon tilted toward Pakistan).
- During the Bangladesh War (1971), the USA sent its 7th Fleet to the Bay of Bengal to intimidate India; the USSR countered by sending submarines — both stood down after India's rapid victory.
- India consistently opposed US interventions in Vietnam, Korea and the Middle East.
6. Decolonisation (1945–1975)
The Cold War period coincided with the largest wave of decolonisation in history:
- Asia (1947–57): India/Pakistan (1947), Burma/Ceylon (1948), Indonesia (1949), Vietnam (1954), Malaya (1957).
- Africa (1957–75): Ghana (1957), most of sub-Saharan Africa (1960s), Angola/Mozambique (1975 — after Portuguese revolution).
- Middle East: Palestine/Israel (1948), Egypt (Suez Crisis 1956), Algeria (1962 — longest anti-colonial war, 1 million Algerians killed).
Factors in decolonisation:
- European powers weakened by WWII.
- Anti-colonial ideology embedded in the UN Charter.
- US opposition to formal colonialism (though supporting neo-colonialism).
- Growth of nationalist movements.
- USSR's anti-colonial rhetoric giving nationalists an alternative patron.
7. UPSC Relevance
Prelims: Truman Doctrine = 1947; Marshall Plan = 1947; NATO = 1949; Korean War ceasefire = 1953; Cuban Missile Crisis = 1962; Berlin Wall fell = 9 November 1989; USSR dissolved = 25 December 1991; Glasnost/Perestroika = Gorbachev.
Mains GS1: "The Cold War shaped decolonisation as much as nationalist movements did." Discuss. | Evaluate India's Non-Alignment in the context of Cold War bipolarity. | Assess the Cold War's impact on the Middle East — does it explain the current situation?
