Cold War Crises and Proxy Wars

5.1 Key Cold War Crises

Berlin Blockade and Airlift 1948–49

The first major Cold War confrontation arose after the Western Allies introduced a new currency (Deutschmark) in West Germany and the USSR blocked all land routes to West Berlin (June 1948). The USA and Britain responded with a massive airlift — 277,264 flights delivering 2.3 million tons of supplies over 11 months. The Soviets ended the blockade on 12 May 1949; West Berlin was saved. NATO was formed on 4 April 1949, partly as a direct response.

Korean War 1950–53

After WWII, Korea was divided at the 38th Parallel — communist North Korea (backed by USSR and China) vs. democratic South Korea (backed by USA). North Korea invaded South on 25 June 1950. The UN Security Council — USSR boycotting over the China seat — authorised a US-led multinational force. China intervened in November 1950 with 300,000 troops. Armistice signed 27 July 1953 — essentially at the 38th Parallel. Korea remains divided today.

Suez Crisis 1956

Egyptian President Nasser nationalised the Suez Canal (26 July 1956). Britain, France, and Israel secretly attacked Egypt. Both the USA (seeking to distance itself from European colonialism) and USSR (threatening rocket attacks on London and Paris) pressured the aggressors to withdraw. This showed that European powers could no longer act without US approval — a landmark in the post-colonial world order.

Hungarian Revolution 1956

Hungary tried to leave the Warsaw Pact under reformist PM Imre Nagy. The Soviet Union invaded with tanks — 2,500 Hungarians killed, 200,000 fled as refugees. Western countries condemned but did not intervene — exposing the limits of Western Cold War rhetoric.

Cuban Missile Crisis October 1962

The closest the world came to nuclear war:

• 16 October: Kennedy shown U-2 photos of Soviet missile sites under construction in Cuba
• 22 October: Kennedy announces naval quarantine in TV address
• 24 October: Soviet ships approach the quarantine line — then turn back
• 26–27 October: Letters between Kennedy and Khrushchev; a US U-2 shot down over Cuba
• 28 October: Khrushchev agrees to remove missiles; Kennedy pledges not to invade Cuba; secret removal of US Jupiter missiles from Turkey

Lesson: Led to the "Hot Line" agreement (June 1963) — direct telephone link between Washington and Moscow.

Prague Spring 1968

Czechoslovak reformist leader Alexander Dubček attempted "socialism with a human face" — loosening censorship, allowing opposition parties. The Soviet Union and Warsaw Pact invaded Czechoslovakia in August 1968 with 500,000 troops. The Brezhnev Doctrine declared the USSR's right to intervene in any socialist country where socialism was "threatened."

5.2 Proxy Wars: Cold War by Other Means

Vietnam War 1955–75

Perhaps the most significant proxy war. Ho Chi Minh's communist North Vietnam (backed by USSR and China) fought South Vietnam (backed by USA). The Gulf of Tonkin Resolution (August 1964) authorised full US involvement; peak US deployment reached 543,000 troops (1969).

Key events:

• Tet Offensive (January 1968): Simultaneous communist attacks on 100 South Vietnamese cities — shocked American public; turned opinion against the war
• Paris Peace Accords (27 January 1973): US withdrew; South Vietnam fell 30 April 1975; Vietnam unified as socialist republic
• Cost: 58,318 American deaths; 3–4 million Vietnamese deaths

Afghanistan 1979–89

A defining proxy war of the late Cold War. The USSR invaded Afghanistan in December 1979 to prop up the communist PDPA government. The USA (under Carter, then Reagan) provided the Afghan Mujahideen with $3 billion in covert aid, including Stinger anti-aircraft missiles.

• 9 years of warfare: 15,000 Soviet troops killed; 1–2 million Afghans killed; 5 million became refugees
• Soviets withdrew February 1989; Afghanistan descended into civil war — setting the stage for the Taliban rise and 9/11

Angola, Mozambique, Congo, Nicaragua, El Salvador

In Africa and Latin America, the USSR and Cuba backed leftist liberation movements while the USA backed right-wing governments or anti-communist rebels. These conflicts killed hundreds of thousands and left lasting political instability.

India-Pakistan Wars and the Cold War

India-Pakistan wars of 1965 and 1971 had Cold War dimensions. The US backed Pakistan (a CENTO/SEATO member); the USSR backed India (Indo-Soviet Treaty of Peace, Friendship and Cooperation, August 1971). During the 1971 war the US sent the USS Enterprise carrier group to the Bay of Bengal as a show of force — India and the USSR saw it as a threat.
