The Vietnam War was a conflict between North Vietnam and South Vietnam that lasted from 1955 to 1975. It began as a war between Vietnam and France but later expanded with the United States supporting South Vietnam to contain the spread of communism. Despite massive U.S. military involvement, the war ended with a communist victory in 1975 as North Vietnam unified the country under communist rule.

○ Goal: To rid Vietnam of French and Japanese occupiers
● In 1945 Ho Chi Minh and his People's Congress create the National
Liberation Committee of Vietnam to form a provisional government.
● On September 2, 1945, after gaining support for their cause, the Viet Minh
announced the Vietnam Democratic Republic as an independent state and
sought recognition from the US, UK, Soviet Union, and China

communism.

8. French Seizure of Haiphong
and Langs

Geneva Conference agree to split
Vietnam at Seventeenth Parallel.
(Communist North and Anti-
communist South)
● elections were supposed to be
held in 1956 for reunification
○ US thought that this would
give too much power to the
Communist Party of
Vietnam

10. US Fear of Communist
Takeover
● the United States began supporting France in the effort to defend its
colonial presence in Vietnam.
○ the US did this to contain communism, making it an indirect conflict
between the US and the USSR in the cold war.
■ Remembering the failure of appeasement before World War II,
policy makers turn to aggression
■ Johnson asserted that the "central lesson of our time is that the
appetite of aggression is never satisfied. To withdraw from one
battlefield means only to prepare for the next."
■ Domino Theory

11. Domino Theory
● The US belief that if Vietnam fell into communism, its neighbors would
follow in a chain reaction leading to possibly all of Southeast Asia under
communist rule.
○ Truman Doctrine
● Dwight D. Eisenhower: first to bring up this idea-Containment of
Communism
"You have a row of dominoes set up, you knock over the first one, and what will happen to the last one is the certainty
that it will go over very quickly. So you have a beginning of a disintegration that would have the most profound
influences."

shelter and fighting bases
● Popular support is crucial to
