What this dot point is asking
NESA expects you to explain how the Cold War was fought in the Third World, with Vietnam and Afghanistan as the two paradigmatic superpower interventions, and how each war damaged the intervening superpower while exhausting the opposing system's resources.
The answer
The Cold War and the Third World
The Cold War became a global rivalry in the late 1950s as decolonisation produced new states. Khrushchev's January 1961 speech on "wars of national liberation" announced Soviet support for anti-colonial insurgency. American policy under Kennedy and Johnson framed Third World interventions as containment.
Significant proxy conflicts: the Congo crisis (1960 to 1965), the Angolan Civil War (1975 to 2002 with Cuban and Soviet support for the MPLA against the FNLA and UNITA), the Ethiopian-Somali Ogaden War (1977 to 1978), the Nicaraguan Revolution and Contra War (1979 to 1990), and the proxy wars in Mozambique, Cambodia, and Yemen.
The two paradigmatic cases were Vietnam and Afghanistan, the longest and most strategically damaging.
The Vietnam War, 1955 to 1975
The American commitment to Vietnam built up gradually. After the French defeat at Dien Bien Phu (7 May 1954) and the Geneva Accords (21 July 1954), Vietnam was partitioned at the 17th parallel pending reunification elections that were not held. The Eisenhower administration backed the Ngo Dinh Diem government in South Vietnam with military advisers. By 1960 the National Liberation Front (NLF, Viet Cong) had begun armed insurgency.
The Kennedy administration expanded the advisory mission to 16,300 by November 1963. The Diem government's coup and assassination (1 to 2 November 1963), partly American-encouraged, produced a series of unstable South Vietnamese governments.
The Gulf of Tonkin Resolution (7 August 1964) authorised Johnson "to take all necessary measures" after the alleged North Vietnamese attacks of 2 and 4 August. The second attack probably did not occur.
Johnson committed combat troops from March 1965 (Operation Rolling Thunder bombing began 2 March; Marines landed at Danang 8 March). American forces peaked at 543,400 in April 1969.
The Tet Offensive (30 January to 23 February 1968) was a tactical defeat for the NLF but a strategic catastrophe for the American war effort. Walter Cronkite's "we are mired in stalemate" broadcast (27 February 1968) shifted American public opinion. Johnson declined to seek re-election on 31 March 1968.
Nixon's Vietnamisation policy from 1969 transferred combat to the ARVN. The Cambodia incursion (May 1970), the Laos incursion (Operation Lam Son 719, February 1971), and the Christmas bombing (Linebacker II, December 1972) accompanied gradual withdrawal. The Paris Peace Accords (27 January 1973) ended American combat involvement.
The collapse came in 1975. The North Vietnamese spring offensive captured Hue (25 March), Da Nang (29 March), and Saigon on 30 April 1975. The American embassy was evacuated by helicopter on 29 to 30 April.
Casualties: about 58,220 Americans dead, 153,303 wounded; approximately 1.1 million North Vietnamese and NLF dead; approximately 250,000 ARVN dead; civilian dead in the millions.
Vietnam's strategic impact on the United States
Domestic: the anti-war movement (Moratorium March, 15 October 1969, 2 million participants; the Kent State shootings, 4 May 1970), the Pentagon Papers (June 1971), Watergate and Nixon's resignation (9 August 1974). The War Powers Act (7 November 1973) constrained presidential war-making.
Strategic: the "Vietnam syndrome" or post-Vietnam syndrome reduced American willingness to intervene with ground forces for a decade. The volunteer army replaced conscription (1973). Reagan's interventions in the 1980s (Grenada, October 1983; Lebanon 1982 to 1984; Panama, December 1989) were calibrated to avoid Vietnam-scale commitment.
Credibility: American allies in Europe and Asia questioned American resolve; the Nixon Doctrine (25 July 1969) reduced American direct commitment. The post-1975 period was the high-water mark of Soviet adventurism in the Third World.
The Soviet war in Afghanistan, 1979 to 1989
The April 1978 Saur Revolution brought the People's Democratic Party of Afghanistan (PDPA) to power under Nur Mohammad Taraki. Rapid land and gender reforms provoked rural Islamic resistance from 1978. Hafizullah Amin overthrew and murdered Taraki in September 1979. The Soviet Politburo, alarmed at Amin's perceived independence and possible American ties, authorised intervention on 12 December 1979.
The invasion began on 24 December 1979 with Soviet airborne troops at Kabul airport. KGB special forces (Operation Storm-333, 27 December) killed Amin and installed Babrak Karmal. Soviet ground forces (eventually about 115,000 at peak) deployed across major cities and roads.
The war was a counter-insurgency against the mujahideen, who received American CIA support through Pakistan's ISI (Operation Cyclone, from January 1980). Saudi Arabia matched American funding. Stinger missiles supplied from 1986 effectively grounded Soviet helicopter mobility. The Sino-Soviet split meant China also supported the mujahideen.
Soviet tactics: cordon-and-search operations, bombing of rural villages, mining of agricultural land. Refugees: approximately 6 million Afghans fled to Pakistan and Iran by the mid-1980s. Civilian dead: approximately 1 million.
Gorbachev publicly described Afghanistan as a "bleeding wound" (February 1986). The Geneva Accords (14 April 1988) provided for Soviet withdrawal in exchange for non-interference commitments. Withdrawal began 15 May 1988 and ended on 15 February 1989 when General Boris Gromov walked across the Friendship Bridge at Termez.
The PDPA regime under Najibullah survived until 1992, falling after Soviet aid was cut off in January 1992.
Soviet casualties: approximately 15,000 dead, 35,000 wounded, plus the post-war psychological damage to the afgantsy (Afghan veterans).
Afghanistan's strategic impact on the USSR
Economic: about $50 billion direct cost, in an economy under increasing strain.
Domestic: the war undermined the prestige of the Soviet military and Communist Party. The afgantsy returned to a society where they could not be acknowledged; their criticism contributed to glasnost. The Mothers' Movement (1989) pressed for accountability for war dead.
Strategic: Afghanistan was the third front (after the Brezhnev years' build-up against China and the European deployment of SS-20s) draining Soviet resources. The 1979 invasion ended detente and produced the Carter Doctrine (23 January 1980), the grain embargo, the Moscow Olympics boycott (July 1980), and the SALT II withdrawal.
For the Cold War: the Afghan war contributed to the conditions for the Gorbachev reforms; Gorbachev's commitment to withdraw was a precondition for the New Thinking and the eventual settlement with the West.

Historiography
Vietnam: George Herring's America's Longest War (1979, multiple editions) is the standard one-volume account. Frederik Logevall's Embers of War (2012) and Choosing War (1999) cover the origins. Stanley Karnow's Vietnam: A History (1983) is the classic narrative.
Afghanistan: Rodric Braithwaite's Afgantsy (2011) is the major account from the Soviet side, drawing on Russian sources. Steve Coll's Ghost Wars (2004) covers the American side. Artemy Kalinovsky's A Long Goodbye (2011) details the Soviet withdrawal decision. Odd Arne Westad's The Global Cold War (2005) places both in the Third World Cold War context.
Common exam traps
Treating the wars as identical. The scale, casualties, and economic absorption capacity were very different. Comparison is symmetric but not equivalence.
Forgetting American support for the mujahideen. Operation Cyclone made Afghanistan a direct American-Soviet proxy contest; about $3 billion was spent through Pakistan.
Missing the connection to the end of the Cold War. Afghanistan was a contributing cause of glasnost and of Gorbachev's New Thinking; Vietnam shaped American caution that made Reagan's diplomatic opening to Gorbachev politically possible.
In one sentence
The Vietnam War (American combat 1965 to 1973, fall of Saigon 1975) and the Soviet war in Afghanistan (1979 to 1989) were the paradigmatic Cold War proxy wars in the Third World, both lasting about a decade, both ending in withdrawal and the eventual loss of the client regime, both damaging the intervening superpower's domestic confidence and international credibility, with Afghanistan's contribution to Soviet systemic crisis proportionally greater because it coincided with economic stagnation, glasnost, and the reform crisis that led to 1991.

Practice (NESA)15 marksCompare the impact of the Vietnam War on the United States and the Afghan War on the Soviet Union.Show worked answer →
A 15-mark "compare impact" needs symmetrical structure and judgement.
Similarities. Both were peripheral wars fought to defend a client regime against an insurgency backed by the rival superpower. Both lasted about a decade (American combat 1965 to 1973; Soviet combat 1979 to 1989). Both ended in withdrawal and the eventual collapse of the client regime (South Vietnam 1975; Najibullah's Afghanistan 1992). Both damaged the superpower's domestic confidence and international standing.
Differences in scale. The United States deployed up to 543,000 troops (April 1969) against the USSR's peak of 115,000 (1985). American dead were about 58,000; Soviet dead about 15,000. The American economy bore the cost without major distortion; the Soviet economy was already stagnant when the war began.
Differences in domestic impact. Vietnam produced the anti-war movement, the Nixon resignation (August 1974), and the post-Vietnam syndrome reducing American military intervention for a decade. Afghanistan produced the returning veterans (afgantsy) as critics of the system and was a contributing cause of glasnost.
Strategic impact. Vietnam damaged American credibility but the system absorbed the loss. The 1980s recovery (Reagan defence build-up, INF Treaty) showed resilience. Afghanistan was one component of the systemic Soviet crisis ending in collapse in 1991.
Judgement. Afghanistan was the more damaging in relative terms because it accelerated systemic collapse. Vietnam was more damaging in absolute terms but the United States absorbed it.
