The document provides an overview of the Vietnam War between 1950-1975. It summarizes the key events, people, and outcomes of the war. The United States aimed to prevent the spread of communism in Southeast Asia, while North Vietnam sought to unite Vietnam under communist rule. After initial US support for South Vietnam, the US gradually escalated its involvement until directly engaging in combat operations. Despite massive bombing campaigns and troop increases, the US was unable to defeat the Viet Cong and North Vietnamese forces. Growing domestic opposition to the war led to the US withdrawal and the eventual communist takeover of South Vietnam in 1975.
