Generals in the South Vietnamese Army depose President Ngo Dinh Diem and assassinate Diem and his brother Ngo Dinh Nhu. While U.S. officials have disagreed over U.S. support of a potential coup, in pressuring Diem and cutting U.S. aid, they realize that they are encouraging the South Vietnamese military leaders to move forward. All the same, U.S. Ambassador Henry Cabot Lodge, Jr. and other American officials have little direct impact on the plan or execution of the coup.

After President Ngo Dinh Diem’s overthrow, South Vietnam enters a period of even greater instability. The Diem regime’s elimination does not offer a remedy for the country’s political or institutional problems, and the bureaucratic structure in South Vietnam continues to deteriorate. A series of additional coups ensues over the next few years and power fluctuates between separate anti-Diem factions. Most of these new governments only last for months.1
