United States Ambassador to South Vietnam Henry Cabot Lodge Jr. reported to Washington that the new President of South Vietnam Dương Văn Minh told him that he opposed American soldiers going into villages and districts of rural Vietnam as they would be perceived as "more imperialistic than the French" and would give credence to communist propaganda that the Saigon government was a lackey of the United States.

Theodore Sorensen, one of former President John F. Kennedy's most trusted aides, wrote President Johnson to oppose the neutralization of South Vietnam as proposed by French President Charles de Gaulle and others.
Sorensoen said neutralization would result in a communist takeover of South Vietnam, weaken the U.S. position in Asia, and cause political problems for the Democratic Party.
Johnson's principal advisers—Dean Rusk, Robert McNamara, McGeorge Bundy and Walter Rostow—echoed Sorensen's views.
In December, Senator Mike Mansfield had proposed negotiation of a neutral South Vietnam.

20 January
The Central Committee of the Communist Party of Vietnam adopted Resolution 9.
The secret resolution declared all-out war on South Vietnam to defeat the ARVN before the United States could introduce a large number of American soldiers into the war.
The Resolution estimated that American soldiers participating in the war would not exceed 100,000.
The Americans "clearly understand that if they get bogged down in a large-scale protracted war, then they will fall into an extremely defensive position internationally."
Diplomacy would be expanded to gain "the sympathy of antiwar groups in the United States" and other people around the world.
Finally, the Resolution called for a purge of party members in North Vietnam who had emphasized socialistic development in North Vietnam rather than North Vietnamese help for the "liberation" of the South.

Resolution 9 was the most important Communist party decision on action in South Vietnam since the Geneva Accords of 1954, which had provisionally separated North and South Vietnam pending national elections (never held, due to opposition by the government of South Vietnam).

With the adoption of Resolution 9, party moderates such as Ho Chi Minh and Võ Nguyên Giáp were marginalized, and militant leaders such as Lê Duẩn and Lê Đức Thọ took command of the Communist Party and North Vietnam.

The U.S. Joint Chiefs of Staff sent a classified memorandum to U.S. Secretary of Defense McNamara, urging an expansion of U.S. involvement in the war, advocating heavy bombing of North Vietnam, and deployment of troops in South Vietnam for an eventual invasion of the North.

General Nguyễn Khánh led a successful coup ousting the military junta led by General Dương Văn Minh from the leadership of South Vietnam.
It came less than three months after Minh's junta had come to power in a coup d'état which overthrew and killed then President Ngô Đình Diệm.
The only casualty of the coup was the execution of Minh's aide, Major Nguyen Van Nhung, and lasted only a few hours.
Khánh would allow Minh to resume the office of President nine days later and place himself in the role of prime minister.
Minh's colleagues, Generals Tran Van Don, Le Van Kim and Ton That Dinh were placed under house arrest, accused of planning a neutralist takeover of South Vietnam.
