The war in Vietnam
For 12 years, the United States was engaged in a futile war, Trying to prevent South Vietnam, then as the Republic of Vietnam, from begin taken over by the North (The Democratic Republic of Vietnam).
The United States' involvement in Vietnam began in the early 1960s, a time when many Asian countries were trying
to achieve independence from their colonial rules. The Communists had just defeated the Kuomintang in China, and
non-Communist countries were alarmed at the possibility of nationalists being supported by Communist China or the
Soviet Union.
