Proxy Wars from Korea to Angola
A proxy war is a conflict where two rival powers avoid fighting each other directly and instead arm, fund, and advise opposing local sides, letting the superpowers compete without risking direct, potentially nuclear, war.
After 1945 the United States and the Soviet Union both had nuclear weapons, and direct war between them risked ending in mutual destruction. So instead of fighting each other, they fought through other people. Each superpower picked a side in local conflicts already simmering from decolonization or civil war, then poured in money, weapons, training, and advisers. The local combatants did the dying. The superpowers got to expand their influence, test weapons and ideas, and deny Soviet or American troops were ever really there.
Korea shows the pattern early: in 1950 communist North Korea, backed by the Soviet Union and soon China, invaded the American-backed South. The front line swept down to Pusan, back up near the Chinese border, and down again before settling near the original 38th parallel by 1953, roughly where it started, after millions of deaths. Vietnam followed a longer arc: France lost its colony at Dien Bien Phu in 1954, the country split, and the United States stepped in to prop up South Vietnam against the Soviet- and Chinese-backed North, escalating from advisers to half a million troops before withdrawing in 1973 without winning. Angola in the 1970s repeated the formula on a new continent as it broke from Portugal.
These wars sit inside Unit 8's larger story: decolonization created dozens of new, fragile states, and the Cold War turned many of their internal struggles into superpower battlegrounds. The proxy label explains who was funding and arming each side. It says nothing about how real the fighting was for the people living through it.

- Worked exampleTrace Vietnam from the French defeat in 1954 to American escalation to withdrawal in 1973.
- Common mistakeWhy doesn't calling Vietnam a proxy war make the fighting and dying there any less real?
