President Kennedy and Vietnam, 1961-1963
The government of the Republic of Vietnam, led by President Ngo Dinh Diem in the South, faced opposition from the Viet Minh.

It set up the National Liberation Front (NLF), which aimed to:
- organise the various resistance groups already in South Vietnam
- support the North Vietnamese Army (NVA)in the South
- assassinate South Vietnamese government officials
Before John F Kennedy was elected president, he had promised to prevent the spread of communism in places like Vietnam. After his election, he launched Operation Beef Up to help President Diem combat the Viet Minh. This operation had the following results:
- It increased the number of US troops in South Vietnam from just over 3,000 in 1961 to 17,000 in 1963.
- It established the Military Assistance Command, Vietnam, to coordinate US support for South Vietnam.
- It allowed US troops to secretly support the actions of the Army of the Republic of Vietnam (ARVN).
- It encouraged Diem to make social and political reforms to make his government more popular.

The overthrow of President Ngo Dinh Diem
Despite the support of the USA, President Diem became increasingly unpopular in South Vietnam. There were many reasons for this:
- Although the majority of the Vietnamese people were Buddhists. Diem and his government openly discriminated against Buddhists.
- Diem carried out land reforms that took land away from local people and gave it to landlords.
- Diem gave government jobs to his family and was seen as a corrupt politician.
- The Strategic Hamlet Program was deeply unpopular because villagers were forced to move away from their ancestral homes. By 1962, there were around 3,000 Strategic Hamlets, but the policy did not last long because the Viet Cong targeted them and the people living in them hated them.

By 1963, it was clear to the USA that they were supporting a corrupt government that stood little chance of uniting South Vietnam with the communist North. Diem's anti-Buddhist measures and the persecution of Buddhists in the country led to Buddhist monks setting themselves on fire to protest about his government’s policies. At that point, President Kennedy decided to cut off the aid it was giving Diem.

The government of South Vietnam remained under unstable military rule until Nguyen Van Thieu took over as president in 1967.
