Key Idea: No war is decided by just one thing. Historians look at four factors together: leadership, strategy and tactics, resource mobilization, and technology. A side wins a conflict when these factors fit together — strong leadership choosing the right strategy, backed by enough resources and technology to carry it out. Miss one piece and even a materially stronger side can lose, as the USA discovered in Vietnam.
How this topic is tested
Topic 6.2 is examined in Paper 2, a thematic essay paper. You never write about only one country here — you always compare across regions.
Section A asks a concept mini-essay [6 marks] — e.g. define and briefly illustrate a term like 'coalition' or 'insurgency'. Section B(a) asks you to explain something [4 marks] — e.g. explain one reason resources mattered in a named conflict. Section B(b) is the big one [15 marks]: a 'to what extent' essay. You MUST use at least two conflicts from at least two different regions — never write about only one war.
Must-know facts — the whole of 6.2 in one place
This topic has only one micro (6.2.1), but it teaches four factors through two contrasting case studies: WWII in Europe and the Vietnam War in Asia & Oceania. Know both cases for each factor.
| Factor | Europe — WWII (1939–1945) | Asia & Oceania — Vietnam War (1955–1975) |
|---|---|---|
| Leadership | Churchill, Roosevelt & Stalin built a coalition at conferences (Tehran 1943, Yalta 1945); Eisenhower coordinated the multinational D-Day landings (June 1944) | Ho Chi Minh and General Vo Nguyen Giap sustained political will for a long war of independence; US public and congressional support collapsed after the Tet Offensive (1968), forcing troop withdrawal by 1973 and the fall of Saigon in 1975 |
| Strategy & tactics | Conventional attrition and combined-arms warfare across multiple fronts, grinding Germany down | Guerrilla insurgency and protracted war — hit-and-run attacks, jungle ambushes, using the Ho Chi Minh Trail to avoid open battles the US would win |
| Resource mobilization | US industry built 300,000+ aircraft and 88,000 tanks by 1945; the Lend-Lease Act (1941) funnelled US supplies to Allies; huge manpower from the USSR and British Empire | Limited industry compared to the USA; relied on aid from the USSR and China, never matching American resources |
| Technology | Radar won the Battle of Britain (1940); Allied air power after 1943 destroyed German industry and oil; codebreaking at Bletchley Park (Enigma) sank U-boats and revealed enemy plans | Superior US technology — helicopters, napalm, Agent Orange, B-52 bombing — blunted by jungle terrain, tunnel networks, and an insurgent enemy blending into the population |
- Coalition — an alliance of states fighting together for a shared goal, like Britain, the USSR and the USA after 1941
- Conventional warfare — large armies fighting openly with regular tactics, as the US did in Vietnam
- Perspectives — Allied leaders saw WWII as a war for survival and liberation; some commanders and historians blame Hitler's strategic interference (like the 1941 invasion of the USSR) for German defeat
- Significance — Vietnam shows that material superiority is not enough; a materially weaker side can win by making the political cost of war unbearable for the stronger side
To what extent was resource mobilization the most important factor in determining the outcome of a conflict? Support your answer with reference to two conflicts, each from a different region.

Important: Do not just list factors — 'leadership, strategy, resources, technology' — without explaining HOW each one changed the result in a specific conflict. Always say what happened, then say why it mattered for who won. And never write about only one region: Paper 2 essays require examples from at least two.
What four factors determine a conflict's outcome? Leadership (command decisions, political will, coalitions), strategy and tactics (conventional vs guerrilla), resource mobilization (industry, manpower, finance, allies), and technology (weapons, logistics, communications).
How did the Allied coalition coordinate strategy in WWII? Churchill, Roosevelt and Stalin met at conferences like Tehran (1943) and Yalta (1945) to agree joint strategy, such as opening a Western Front via D-Day (June 1944) while the Soviets pushed from the east.
Why did the USA lose in Vietnam despite superior resources? North Vietnam used guerrilla insurgency and protracted war to avoid open battles, wore down US political will over years, and used terrain and tunnel networks to blunt superior US technology like helicopters and B-52 bombers.
Name three technologies that gave the Allies an edge in WWII. Radar (early warning that won the Battle of Britain, 1940), air power (destroying German industry and oil after 1943), and codebreaking (Bletchley Park breaking Enigma to sink U-boats and reveal enemy plans).
What is a coalition, and why did it matter? An alliance of states fighting together for a shared goal. The WWII Allied coalition (Britain, USSR, USA) held together despite ideological differences, letting them coordinate resources and strategy across multiple fronts.
How does the Vietnam War prove material superiority isn't enough? The USA had far greater industry, technology and firepower than North Vietnam, yet lost because political will collapsed at home while North Vietnam's leadership sustained a long guerrilla struggle.
Always pair a factor with a specific example and explain its effect — never just name it. Use two conflicts from two different regions in every Section B(b) essay. Remember factors interact: WWII shows resources + strategy + technology working together; Vietnam shows how political will and strategy can defeat material superiority alone.
