What is vietnam war?
The Vietnam War lasted from November 1, 1955, to the fall of Saigon on April 30, 1975, in Vietnam, Laos, and Cambodia. It was the second of the Indochina Wars, and it was fought between North and South Vietnam.
The Vietnam War characterized 1960s and 1970s America, but by the most frequently accepted yardstick, it lasted ten years (and, officially, it was never a war at all). While World Wars I and II killed significantly more American troops, the conflict did not last a decade and a half.
