The Cold War in Asia (1949–2002)

The line of latitude chosen by the USA and USSR to divide Korea temporarily for accepting the Japanese surrender — never intended as a permanent border.

Kim Il Sung, installed with Soviet backing in 1948; he wanted to reunify Korea under communist rule and pushed Stalin and Mao to support an invasion of the South.

Syngman Rhee, a US-backed anti-communist president from 1948; his government was authoritarian, and he too wanted a unified Korea, under his own rule.

25 June 1950 — North Korean forces invaded South Korea across the 38th parallel; Seoul fell within days.

Because the USSR was boycotting the Council at the time (over China's UN seat) and so could not use its veto to block the vote.

A surprise amphibious landing led by General MacArthur (15 September 1950) far behind North Korean lines; it cut enemy supply lines and let UN forces retake Seoul.

UN forces advanced toward the Yalu River (China's border) after Inchon; China saw this as a direct security threat and sent Chinese People's Volunteers to push UN troops back.

Truman removed him for publicly pushing for wider war with China (including possible nuclear use) against White House strategy — showing civilian control over the military.

Disagreement over prisoner-of-war repatriation: the UN side wanted POWs to choose freely, the Communist side demanded automatic return of all POWs.

27 July 1953, at Panmunjom — a ceasefire, not a peace treaty, so North and South Korea remain technically at war.

The Demilitarised Zone — a roughly 4 km-wide buffer strip along the 1953 ceasefire line, still one of the most heavily fortified borders in the world.

It began with genuine civil-war roots (rival Korean leaders both wanting unification), but Stalin's approval and Chinese/US involvement made it function largely as a Cold War proxy conflict once underway.

Việt Minh forces under Giáp besieged and defeated the French garrison, ending French rule in Indochina.

Agreement splitting Vietnam at the 17th parallel into communist North and non-communist South, with elections promised for 1956 that never happened.

US-backed leader of South Vietnam who favoured Catholics, jailed critics, cracked down on Buddhists, and refused land reform — losing popular support before being overthrown in 1963.

Alleged attacks on US destroyers used to justify the Gulf of Tonkin Resolution, giving Johnson broad war powers in Vietnam.

US troops swept areas hunting Việt Cộng fighters then withdrew rather than holding territory — it destroyed villages and alienated civilians without securing lasting gains.

Though a military defeat for the communists, the surprise scale of the attacks shocked US public opinion and became the war's key political turning point.

Militarily: communist forces suffered heavy losses and held no city long. Politically: US confidence in the war collapsed and Johnson chose not to seek re-election.

Nixon's policy of gradually shifting combat responsibility to South Vietnamese forces while withdrawing US troops.

North Vietnamese tanks entered Saigon; South Vietnam collapsed, leading to reunification under communist rule in 1976.

Secret US bombing of communist supply routes and the wider chaos helped the Khmer Rouge grow strong enough to seize power in 1975.

Between 1975-79 the Khmer Rouge regime caused roughly 1.5-2 million deaths through executions, starvation, and forced labour in Cambodia.

A parallel civil war, fuelled by US and North Vietnamese involvement, ended with the communist Pathet Lao taking power the same year Saigon fell.

The April 1978 coup in which the communist PDPA seized power in Afghanistan, killing President Daoud and installing Nur Muhammad Taraki.

Land reform, forced literacy for girls, and attacks on tribal and religious authority struck at the core of rural Afghan life, sparking revolts within months.

Moscow feared Hafizullah Amin's unstable, brutal rule would let the communist government collapse to Islamist rebels, so Soviet forces killed Amin and installed Babrak Karmal.

Afghan resistance fighters organised by tribe and region who framed their war against PDPA and Soviet forces as jihad, a religious struggle.

USA (money and Stinger missiles via the CIA's Operation Cyclone), Pakistan (training camps and arms distribution via the ISI), Saudi Arabia (funding and volunteer fighters, including Osama bin Laden).

US-supplied Stinger missiles let the Mujahideen shoot down Soviet helicopters and aircraft, blunting the Soviets' key air-power advantage and raising their losses.

February 1989, following the 1988 Geneva Accords signed under Mikhail Gorbachev.

It drained Soviet money and morale, cost thousands of lives, and fed the climate of open criticism unleashed by Gorbachev's glasnost, though it was one factor among several (with economic stagnation and nationalist movements).

It collapsed once Soviet aid ended after the USSR's 1991 dissolution, and Mujahideen factions took Kabul, triggering a civil war.

Amid the 1992-96 civil war between rival Mujahideen warlords, the Taliban, religious students promising to end corruption and restore order through strict Islamic law, captured Kabul in 1996.

Al-Qaeda's 9/11 attacks (2001) led the USA to demand the Taliban hand over Osama bin Laden; when they refused, a US-led coalition invaded in October 2001 and toppled the Taliban regime by December 2001.

Both saw a superpower with superior technology fail to defeat a determined, foreign-backed guerrilla movement, suffer rising costs and casualties, and eventually withdraw without achieving its goals.
