"Why We Fight In Viet-Nam"

This document was published by the U.S. Department of State. It argues that the Vietnam War happened because North Vietnam broke the Geneva Agreement by continuing to support attacks in the South after 1954. It explains that America joined the fight not only to keep its promise to South Vietnam, but also to stop the spread of communism, protect important areas in Asia, and defend the right of nations to decide their own futures without violence.
