9. Vietnam War (1955-1975)
The Vietnam War was a protracted civil conflict between communist North Vietnam and US-backed South Vietnam, drawing in superpowers and regional neighbors. Guerrilla warfare, foreign intervention, and ideological fervor turned Vietnam into a battleground of the Cold War. The war’s devastating toll on civilians and its divisive legacy continue to shape Southeast Asian politics. The eventual reunification under communist rule marked a turning point, influencing anti-war movements, US foreign policy, and the region’s development for decades to come.
