The US was supporting South Vietnam. The US opposed the communist North Vietnam, which was led by Ho Chi Minh. South Vietnam was ruled by President Diem (pronounced like Z-M) who was later assassinated by South Vietnam rebels.
The people of South Vietnam rebelled against Diem because he was Catholic and tried to change the people's religion form Buddhism to Catholicism. Kennedy and everyone saw the pictures of the Buddhist monks setting themselves on fire and it leaked out that the US favored a coup (pronounced like coo) and the takeover by other officials led to the assassination of Diem.
Kennedy also funded a CIA operation which encouraged the overthrow, and indirectly ended in Diem's assassination.
