Who began plotting a coup to overthrow Ngo Dinh Diem?
Several attempts had already been made to overthrow Diem but Kennedy had always instructed the CIA and the US military forces in Vietnam to protect him. [ In order to obtain a more popular leader of South Vietnam, Kennedy agreed that the role of the CIA should change. Lucien Conein, a CIA operative, provided a group of South Vietnamese generals with $40,000 to carry out the coup with the promise
that US forces would make no attempt to protect Diem.
At the beginning of November, 1963, President Diem was overthrown by a military coup. After the generals had promised Diem that he would be allowed to leave the country they changed their mind and killed him. He was replaced by Nguyen Van Thieu, the chief of staff of the Armed Forces of South Vietnam. ]
