Source: President Johnson's Message to Congress August 5, 1964

Last night I announced to the American people that the North Vietnamese regime had conducted further deliberate attacks against U.S. naval vessels operating in international waters, and I had therefore directed air action against gunboats and supporting facilities used in these hostile operations. This air action has now been carried out with substantial damage to the boats and facilities. Two U.S. aircraft were lost in the action.

After consultation with the leaders of both parties in the Congress, I further announced a decision to ask the Congress for a resolution expressing the unity and determination of the United States in supporting freedom and in protecting peace in southeast Asia.

These latest actions of the North Vietnamese regime has given a new and grave turn to the already serious situation in southeast Asia. Our commitments in that area are well known to the Congress. They were first made in 1954 by President Eisenhower. They were further defined in the Southeast Asia Collective Defense Treaty approved by the Senate in February 1955.

This treaty with its accompanying protocol obligates the United States and other members to act in accordance with their constitutional processes to meet Communist aggression against any of the parties or protocol states.

Our policy in southeast Asia has been consistent and unchanged since 1954. I summarized it on June 2 in four simple propositions:

America keeps her word. Here as elsewhere, we must and shall honor our commitments.

The issue is the future of southeast Asia as a whole. A threat to any nation in that region is a threat to all, and a threat to us.

Our purpose is peace. We have no military, political, or territorial ambitions in the area.

This is not just a jungle war, but a struggle for freedom on every front of human activity. Our military and economic assistance to South Vietnam and Laos in particular has the purpose of helping these countries to repel aggression and strengthen their independence.

The threat to the free nations of southeast Asia has long been clear. The North Vietnamese regime has constantly sought to take over South Vietnam and Laos. This Communist regime has violated the Geneva accords for Vietnam. It has systematically conducted a campaign of subversion, which includes the direction, training, and supply of personnel and arms for the conduct of guerrilla warfare in South Vietnamese territory. In Laos, the North Vietnamese regime has maintained military forces, used Laotian territory for infiltration into South Vietnam, and most recently carried out combat operations - all in direct violation of the Geneva Agreements of 1962.

In recent months, the actions of the North Vietnamese regime have become steadily more threatening...

As President of the United States I have concluded that I should now ask the Congress, on its part, to join in affirming the national determination that all such attacks will be met, and that the United States will continue in its basic policy of assisting the free nations of the area to defend their freedom.

As I have repeatedly made clear, the United States intends no rashness, and seeks no wider war. We must make it clear to all that the United States is united in its determination to bring about the end of Communist subversion and aggression in the area. We seek the full and effective restoration of the international agreements signed in Geneva in 1954, with respect to South Vietnam, and again in Geneva in 1962, with respect to Laos . . .
