l. United States National Interests in South Viet-Nam.

The deteriorating situation in South Viet-Nam requires attention to the nature and scope of United States national interests in that country. The loss of South Viet-Nam to Communism would involve the transfer of a nation of 20 million people from the free world to the Communism bloc. The loss of South Viet-Nam would make pointless any further discussion about the importance of Southeast Asia to the free world; we would have to face the near certainty that the remainder of Southeast Asia and Indonesia would move to a complete accommodation with Communism, if not formal incorporation with the Communist bloc. The United States, as a member of SEATO, has commitments with respect to South Viet-Nam under the Protocol to the SEATO Treaty. Additionally, in a formal statement at the conclusion session of the 1954 Geneva Conference, the United States representative stated that the United States "would view any renewal of the aggression . . . with grave concern and seriously threatening international peace and security."
The loss of South Viet-Nam to Communism would not only destroy SEATO but would undermine the credibility of American commitments elsewhere. Further, loss of South Viet-Nam would stimulate bitter domestic controversies in the United States and would be seized upon by extreme elements to divide the country and harass the Administration...

3. The United States' Objective in South Viet-Nam

The United States should commit itself to the clear objective of preventing the fall of South Viet-Nam to Communist [sic]. The basic means for accomplishing this objective must be to put the Government of South Viet-Nam into a position to win its own war against the Guerrillas. We must insist that that Government itself take the measures necessary for that purpose in exchange for large-scale United States assistance in the military, economic and political fields. At the same time we must recognize that it will probably not be possible for the GVN to win this war as long as the flow of men and supplies from North Viet-Nam continues unchecked and the guerrillas enjoy a safe sanctuary in neighboring territory.
We should be prepared to introduce United States combat forces if that should become necessary for success. Dependent upon the circumstances, it may also be necessary for United States forces to strike at the source of the aggression in North Viet-Nam.

4. The Use of United States Forces in South Viet-Nam.

The commitment of United States forces to South Viet-Nam involves two different catgories: (A) Units of modest size required for the direct support of South Viet-Namese military effort, such as communications, helicopter and other forms of airlift, reconnaissance aircraft, naval patrols, intelligence units, etc., and (B) larger organized units with actual or potential direct military mission. Category (A) should be introduced as speedily as possible. Category (B) units pose a more serious problem in that they are much more significant from the point of view of domestic and international political factors and greatly increase the probabilities of Communist bloc escalation. Further, the employment of United States combat forces (in the absence of Communist bloc escalation) involves a certain dilemma: if there is a strong South Viet Namese effort, they may not be needed; if there is not such an effort, United States forces could not accomplish their mission in the midst of an apathetic or hostile population. Under present circumstances, therefore, the question of injecting United States and SEATO combat forces should in large part be considered as a contribution to the morale of the South Viet Namese in their own effort to do the principal job themselves....

In the light of the foregoing, the Secretary of State and the Secretary of Defense recommend that:

1. We now take the decision to commit ourselves to the objective of preventing the fall of South Viet-Nam to Communism and that, in doing so, we recognize that the introduction of United States and other SEATO forces may be necessary to achieve this objective. (However, if it is necessary to commit outside forces to achieve the foregoing objective, our decision to introduce United States forces should not be contingent upon unanimous SEATO agreement thereto.)
2. The Department of Defense be prepared with plans for the use of United States forces in South Viet Nam under one or more of the following purposes:

(a) Use of a significant number of United States forces to signify United States determination to defend Viet-Nam and to boost South Viet-Nam morale.
(b) Use of substantial United States forces to assist in suppressing Viet Cong insurgency short of engaging in detailed counter-guerrilla operations but including relevant operations in North Viet-Nam.

(c) Use of United States forces to deal with the situation if there is organized Communist military intervention.

3. We immediately undertake the following actions in support of the GVN:

. . . (d) Provide the GVN with small craft, including such United States uniformed advisers and operating personnel as may be necessary for quick and effective operations in effecting surveillance and control over coastal waters and inland waterways....
(e) Provide such personnel and equipment as may be necessary to prove the military-political intelligence system beginning at the provincial level and extending upward through the Government and the armed forces to the Central Intelligence Organization.
(f) Provide such new terms of reference, reorganization and additional personnel for United States military forces as are required for increased United States participation in the direction and control of GVN military operations and to carry out the other increased responsibilities which accrue to MAAG under these recommendations....
(i) Provide individual administrators and advisers for insertion into the Governmental machinery of South VietNam in types and numbers to be agreed upon by the two Governments....
