CIA activities in Vietnam were operations conducted by the Central Intelligence Agency in Vietnam from the 1950s to the late 1960s, before and during the Vietnam War. After the 1954 Geneva Conference, North Vietnam was controlled by communist forces under Ho Chi Minh's leadership. South Vietnam, with the assistance of the U.S., was anti-communist. The economic and military aid supplied by the U.S. to South Vietnam continued until the 1970s. The CIA participated in both the political and military aspect of the wars in Indochina. The CIA provided suggestions for political platforms, supported candidates, used agency resources to refute electoral fraud charges, manipulated the certification of election results by the South Vietnamese National Assembly, and instituted the Phoenix Program. It worked particularly closely with the ethnic minority Montagnards, Hmong, and Khmer. There are 174 National Intelligence Estimates dealing with Vietnam, issued by the CIA after coordination with the US intelligence community.
Vietnam 1945–1947
Through 1954, Vietnam was part of French Indochina, along with Laos and Cambodia. During the war, the Imperial Japanese Army occupied Vietnam and remained there until 1945, when the Axis powers were defeated. The Japanese were removed from Vietnam with the help of revolutionary leader Ho Chi Minh and his Vietminh forces. Following the war, France began to reoccupy the Indochina region and reassert its former dominance. Much of this can be traced back to a desire to restore French glory and national pride after the humiliation the nation suffered during the course of World War II. The French also wished to reclaim the Indochina region to regain control over the vast rubber plantations across the country.
The people of Vietnam were completely against the return of the French. The Vietnamese experienced a lot of abuses by the French during their colonization in the mid 19th century. The people of North Vietnam rallied around their recently returned revolutionary leader Ho Chi Minh and looked to him to gain at long last, their independence.
The French spent nine years (1946–54) attempting to regain control of Vietnam. France did not realize that the current Vietnamese were much stronger than those that they were familiar with. They greatly underestimated the strength and capability of the Vietnamese force. The Viet Minh, or Viet Cong as they came to be called, were not going to let the French take control of their region without a fight. The men of the Viet Cong were communists and did not want to surrender their beliefs to the French. Together with the North Vietnamese army, they would defend their land. The Vietnamese used military and political tactics to push and expel the French from their lands. North Vietnamese troops were prepared to fight the French to the bitter end in order to ensure victory and their freedom. The loss of thousands of French men made it easy for North Vietnam and the Viet Cong to win the war. France lost a lot of their supporters of the war after many of their men were killed. It was also beneficial to the North Vietnamese efforts when they began to receive outside assistance. The Soviet Union sent them military hardware that they used in combat against the French. After suffering a major defeat at the fortress of Dien Bien Phu on May 7, 1954, the French lost control of Viet Nam above latitude 17 degrees north; this became the Democratic Republic of Viet Nam. Soviet- and Chinese-made weapons and captured American ones given to the North Vietnamese army by China played a key role in the defeat of France.
Even before the CIA was formed, teams from the OSS, including one under Major Archimedes Patti, was in French Indochina, assessing the situation, and discussing alternatives with parties on all sides, including Ho Chi Minh.
Vietnam 1950–1954
CIA officers moved to French Indochina in 1950 as a part of the legation of the United States in the city of Saigon. After their arrival, CIA involvement expanded to a new large base in Hanoi. The CIA's activities in Vietnam did not grow any further due to the French discouraging CIA activity (the French were still clinging to the idea that they could one day still dominate Vietnam and the U.S. was against this course of action).
CIA involvement in Vietnam was discouraged by the French because it was found that the CIA would often bypass them to open channels to Vietnamese nationalists. CIA activity expanded when the Indochina region became three separate states, and grew exponentially during the French War in 1953 to 1954 when France was essentially forced to accept American assistance with unconventional warfare activities.
