The Vietnam War lasted 20 years (1955-1975) with 58,220 US deaths, while the Korean War lasted 3 years (1950-1953) with 36,574 US deaths. The Korean War ended in armistice with a divided peninsula, whereas the Vietnam War concluded with North Vietnamese victory and reunification.
Both wars were pivotal Cold War conflicts with devastating human costs, but differed significantly in duration, scale, and outcomes. The Korean War was shorter and more geographically contained, while the Vietnam War was prolonged, more destructive, and resulted in complete communist victory. Neither conflict achieved lasting peace, as Korea remains divided while Vietnam eventually unified under communist control.
