Explain how the Cold War was fought through proxy wars and crises: the Korean War, the Cuban Missile Crisis, the Vietnam War, and the space and arms races (Framework Key Idea 10.9).

What this topic is asking

Framework Key Idea 10.9 asks you to explain how the Cold War was actually fought: through proxy wars (such as Korea and Vietnam), dangerous crises (above all the Cuban Missile Crisis), and the arms and space races, rather than direct war between the superpowers. This is a cause-and-effect and turning-point topic, and the Cuban Missile Crisis is a frequent example.

Proxy wars

Two major proxy wars define the period:

• The Korean War (1950 to 1953). Communist North Korea, backed by the Soviet Union and China, invaded South Korea. A United Nations force led by the United States intervened. The war ended in a stalemate, leaving Korea divided near the 38th parallel, as it remains today, a clear example of containment in action.
• The Vietnam War. The United States supported South Vietnam against the communist North (backed by the Soviet Union and China). Despite huge effort, the United States eventually withdrew, and Vietnam was unified under communism in 1975. Vietnam showed the limits of American power and was deeply divisive at home.

The Cuban Missile Crisis

The arms and space races

The superpowers competed fiercely in two technological contests. In the arms race, both built vast arsenals of nuclear weapons, leading to the doctrine of "mutually assured destruction" (each side could destroy the other, so neither dared attack). In the space race, the Soviet Union launched the first satellite (Sputnik, 1957) and the first human into orbit, and the United States responded by landing astronauts on the Moon in 1969. Both races showed how the Cold War rivalry drove science, spending, and national prestige.

Try this

Q1. Name the 1962 crisis that brought the superpowers closest to nuclear war. [Recall]

• Cue. The Cuban Missile Crisis.

Q2. Explain what a proxy war is and give one Cold War example. [Short explanation]

• Cue. A proxy war is one in which rival powers back opposing sides without fighting each other directly; the Korean War (or the Vietnam War), where the United States and the Soviet bloc supported opposite sides, is an example.
