130. Memorandum From the Joint Chiefs of Staff to Secretary of Defense McNamara1

JCSM-652-65

SUBJECT

  • Concept for Vietnam (U)
1.
(S) In the light of the introduction of major US combat units into Southeast Asia, the Joint Chiefs of Staff consider it essential that we further formalize our concept for the future conduct of the war. Recognizing this need, they have developed a concept as set forth in the Appendix. This concept, in which the views of CINCPAC have been considered, envisions the military actions that are part of the over-all US strategy for Southeast Asia, including South Vietnam, North Vietnam, Thailand, and Laos. The correlated military actions to carry out this strategy will be conducted in concert with US major political, economic, and social programs for Southeast Asia. They also will include measures for dealing with the ChiCom threat.
2.
(TS) In summary:
a.
The objective in Vietnam, as stated by NSAM-288, dated 17 March 1964,2 is a stable and independent noncommunist government.
b.
The major problems to be dealt with in the conduct of the war are:
(1)
The continued direction and support of Viet Cong operations by the DRV, infiltration from the north, and the apparent attendant Viet Cong capability to provide materiel support and to replace heavy personnel losses.
(2)
The continued existence of a major Viet Cong infrastructure, both political and military, in the RVN.
(3)
The greater growth rate of Viet Cong strength as compared to that of the South Vietnamese ground forces.
(4)
The continued loss of LOCs, food-producing areas, and population to Viet Cong control.
(5)
The lack of a viable politico/economic structure in the RVN.
(6)
The threat of ChiCom intervention or aggression in Southeast Asia and elsewhere in the Western Pacific.
c.
The basic military tasks, of equal priority, are:
(1)
To cause the DRV to cease its direction and support of the Viet Cong insurgency.
(2)
To defeat the Viet Cong and to extend GVN control over all of the RVN.
(3)
To deter Communist China from direct intervention and to defeat such intervention if it occurs.
d.
The US basic strategy for accomplishing the above tasks should be: to intensify military pressure on the DRV by air and naval power; to destroy significant DRV military targets, including the base of supplies; to interdict supporting LOCs in the DRV; to interdict the infiltration and supply routes into the RVN; to improve the combat effectiveness of the RVNAF; to build and protect bases; to reduce enemy reinforcements; to defeat the Viet Cong, in concert with RVN and third country forces; and to maintain adequate forces in the Western Pacific and elsewhere in readiness to deter and to deal with ChiCom aggression. By aggressive and sustained exploitation of superior military force, the United States/Government of Vietnam would seize and hold the initiative in both the DRV and RVN, keeping the DRV, the Viet Cong, and the PL/VM at a disadvantage, progressively destroying the DRV war-supporting power and defeating the Viet Cong. The physical capability of the DRV to move men and supplies through the Lao Corridor, down the coastline, across the DMZ, and through Cambodia must be reduced to the maximum practical extent by land, naval, and air actions in these areas and against infiltration-connected targets. Finally, included within the basic US military strategy must be a buildup in Thailand to ensure attainment of the proper US-Thai posture to deter ChiCom aggression and to facilitate placing US forces in an advantageous logistic position if such aggression occurs.
3.
(S) The over-all strategic concept for Vietnam, as set forth in the Appendix hereto, provides a basis for terminating the war in Vietnam [Page 358] under conditions which are satisfactory to the United States and the GVN.
4.
(S) The Joint Chiefs of Staff recommend that the attached concept be approved as the basis for subsequent development of courses of action, forces, and other requirements to include the phasing of operations. Recommendations based thereon, including a current evaluation of the capabilities of approved force deployments to achieve the objectives of the concept, will be provided you at the earliest practicable date.

Appendix

OVER-ALL US CONCEPT FOR VIETNAM (U)

Introduction

1. (S) The RVN is a politico/military keystone in Southeast Asia and is symbolic of US determination in Asia—as Berlin is in Europe—to prevent communist expansion. The United States is committed to the defense of the RVN in order to assist a free people to remain free. In addition to the freedom of the RVN, US national prestige, credibility, and honor with respect to world-wide pledges, and declared national policy are at stake. Further, it is incumbent upon the United States at this stage to invalidate the communist concept of “wars of national liberation.”

2. (S) The military operations envisioned in this concept paper must:

a.
Conform to the over-all US strategy and guidelines for Southeast Asia as a whole, including the RVN, DRV, Laos, and Thailand.
b.
Be conducted in concert with appropriate US/GVN political, economic, and social programs in order to guide and to expedite the correlated achievement of US objectives.
c.
Be conceived and evaluated in terms of how much and how well they will contribute to the above.

Factors Bearing on the Development of a US Military Strategy for Vietnam

3. (S) The Viet Cong are directed, controlled, and supported (including heavy military support and encadrement) by their sponsor, [Page 359] the DRV. Viet Cong activities in the RVN are characterized by persuasion through propaganda, intimidation, and terror. Whenever possible, through armed assault and coercion, the Viet Cong destroy the capability of GVN authority to govern, thus progressively reducing the ability of the GVN to bring the population and resources base to bear on the problem. Having assumed control over an area, the Viet Cong install their own political organization and infrastructure. Then, using local manpower and logistics, the Viet Cong organize, equip, and train military units to resist GVN attempts to establish its authority and to expand Viet Cong control and influence into other areas.

4. (S) For the most part, the Viet Cong have sought to avoid a large-scale sustained battle with US/GVN forces. Instead, their tactics have been to maximize the advantages of initiative and surprise and to strike at weakness with overwhelming strength, “fading away” when the combat strength ratio is unfavorable to them. Currently, one of their major objectives appears to be the destruction, through both attrition and demoralization, of the RVNAF.

5. (TS) At present, the Viet Cong and DRV leaders appear confident that their course in the RVN promises ultimate and possibly early success without important concessions on their part. This apparent confidence may have been fostered in part by the current quest for some negotiating arrangement. They seem to believe that they can achieve a series of local military successes which, sooner or later, will bring victory through a combination of a deteriorating South Vietnamese Army (ARVN) morale and effectiveness, a collapse of anti-communist government in Saigon, and an exhaustion of the United States will to persist.

6. (TS) In coping with larger US forces employed in a more aggressive fashion, the Viet Cong would seek to avoid the kind of engagements which risked a serious communist defeat. Instead, they would probably concentrate on harassments intended to bleed and humiliate US forces, attempting to trap and destroy isolated units where possible. At a minimum, the Viet Cong would almost certainly continue present efforts to cut land communications lines and would step up the dispatch of small, expendable teams on sabotage and assassination missions designed to gain propaganda advantages. The communists might also seek to increase their activities in Laos.

7. (TS) Additionally, there is the possibility of ChiCom overt commitment of major combat forces in Southeast Asia and other areas in the Western Pacific. With the greater US involvement in the war in Vietnam, US military posture must be so oriented as to deter ChiCom intervention and defeat this intervention should it occur.

8. (S) The war in Vietnam is the single most critical international problem facing the United States today, and it portends the most serious immediate threat to continued US world leadership and national security. [Page 360] The development of a US strategy for Vietnam is necessarily influenced in varying degrees by the desirability to maintain amicable relations with certain other nations; by the desirability to receive from third countries a degree of support for US policy; by US objectives and alliances elsewhere; by the fact of the sovereignty of the GVN; and, by the necessity to provide an effective Free World counter or answer to “wars of national liberation.”

9. (S) The situation in the RVN has deteriorated to the point where US national objectives are endangered and may not be achieved unless GVN forces are bolstered, adequate security for the South Vietnamese people is provided, and the DRV is persuaded that the risks of further involvement on their part outweigh the gains.

10. (TS) Our strategy for Vietnam should not allow the communists to keep pace with or more than match our military efforts. A program of slowly rising intensity with both sides in step carries with it the danger that it will lead to less flexibility of choice, creeping intervention by the Soviets and Chinese, first with materiel and later with troops, and the eventual engulfing of both camps unwillingly into an expanded war.

11. (TS) Briefly, the major problems to be dealt with in the conduct of the war are:

a.
The continued direction and support of Viet Cong operations by the DRV, including infiltration from the North, and the apparent attendant Viet Cong capability to provide materiel support and to replace heavy personnel losses.
b.
The continued existence of a major Viet Cong infrastructure, both political and military, in the RVN.
c.
The greater growth rate of Viet Cong strength as compared to that of the South Vietnamese ground forces.
d.
The continued loss of LOCs, food-producing areas, and population to Viet Cong control.
e.
The lack of a viable politico/economic structure in the RVN.
f.
The threat of ChiCom intervention or aggression in Southeast Asia and elsewhere in the Western Pacific.

US Objectives, Tasks, and Basic Strategy

12. (TS) US national policy3 includes as an objective in the RVN a stable and independent noncommunist government. Implicit in this objective is the containment of Communist China insofar as expansion into Southeast Asia or elsewhere in the Western Pacific is concerned. Basic military tasks, of equal priority, in support of this objective are:

a.
To cause the DRV to cease its direction and support of the Viet Cong insurgency.
b.
To defeat the Viet Cong and to extend GVN control over all of the RVN.
c.
To deter Communist China from direct intervention and to defeat such intervention if it occurs.

13. (TS) Friendly control of population and resources is essential to success in countering guerrilla warfare. In this regard, the RVN areas of major military significance are: the Saigon area and the Mekong Delta; the coastal plain; and the central highlands. It is imperative that the US/GVN have the support of the people and the control of resources in those areas. Elimination of the Viet Cong from these areas must be vigorously undertaken in order to provide adequate security for the people. Of particular importance is the need for friendly control of the main food-producing areas in order that the GVN may gain control of rice, feed the people under its control, enable exports of rice to bolster the economy, and cause the Viet Cong to import or to fight for food. A paramount requirement under this concept is the building and maintaining of a series of secure bases and secure supporting LOCs at key localities along the sea coast, and elsewhere as necessary, from which offensive operations can be launched and sustained, with the subsequent enlargement and expansion of the secure areas.

14. (TS) The US basic strategy for accomplishing the above tasks should be: to intensify military pressure on the DRV by air and naval power; to destroy significant DRV military targets, including the base of supplies; to interdict supporting LOCs in the DRV; to interdict the infiltration and supply routes into the RVN; to improve the combat effectiveness of the RVNAF; to build and protect bases; to reduce enemy reinforcements; to defeat the Viet Cong in concert with RVN and third country forces; and, to maintain adequate forces in the Western Pacific and elsewhere in readiness to deter and to deal with ChiCom aggression. By aggressive and sustained exploitation of superior military force, the United States/GVN would seize and hold the initiative in both the DRV and the RVN, keeping the DRV, the Viet Cong, and the PL/VM at a disadvantage, progressively destroying the DRV war-supporting power and defeating the Viet Cong. The physical capability of the DRV to move men and supplies through the Lao Corridor, down the coastline, across the DMZ, and through Cambodia, must be reduced to the maximum practical extent by land, naval, and air actions in these areas and against infiltration-connected targets. Finally, included within the basic US military strategy must be a build-up in Thailand to ensure attainment of the proper US-Thai posture to deter ChiCom aggression and to facilitate placing US forces in an advantageous logistic position if such aggression occurs.

Principal Measures for Executing the Basic Strategy and for Achieving US Objectives

15. (TS) In order to gain the offensive and to seize and hold the initiative in the RVN, a major effort must be made not only in terms of direct combat action to expand the areas under US/GVN control but also to support the GVN in its rural reconstruction program and to assist that government in the creation of new military units and the rehabilitation of its depleted units as rapidly as possible. A psychological climate must be created that will foster RVN rural reconstruction progress. It will be noted in paragraph 13 above that, along with the Saigon area, the Mekong Delta is considered of primary importance. While no US land operations are currently envisaged in the Mekong Delta (IV Corps Tactical Zone) because of the comparatively inactive enemy situation now existing there, increased Viet Cong activity could later necessitate US/Third Country operations in that important area.

16. (TS) The intensification of military pressures on the DRV, PL/VM, and the Viet Cong, the destruction of military stocks, supporting facilities, and the interdiction of communist infiltration and supply routes into the RVN will necessarily require:

a.
An immediate acceleration and increase in the scale, scope, and intensity of air and naval actions against the DRV. These actions should be directed against key military and economic targets, the destruction of which should dissuade the DRV from supporting the Viet Cong insurgency; this would include mining of DRV ports. Targets would include these main groupings:POL, LOCs, mines (including coal), military installations, port facilities, and power stations. Attacks against population centers as such would continue to be avoided.
b.
Intensified land, naval, and air actions to reduce infiltration into the RVN. Such actions would include a stepped-up land, sea, and air campaign against infiltration routes, designed to minimize the flow into the RVN of personnel and materiel.

17. (TS) During the build-up phase US/Third Country and GVN forces should strengthen military and civilian control in present areas of the RVN while intensifying air and naval attacks against the DRV and communist infiltration and supply routes into the RVN. As the force build-up is achieved, a principal offensive effort within the RVN of US/Third Country forces should be to participate with the RVNAF in search and destroy operations while assisting the RVNAF in clearing and securing operations in support of the rural reconstruction effort. US/Third Country air and ground operations should be conducted on a sustained basis; attack and destruction of base areas should be directed at applying continuous pressure on the VC to keep them off balance.

18. (TS) To deter ChiCom direct [Page 363] intervention or aggression in Southeast Asia and elsewhere in the Western Pacific, and to deal with such intervention or aggression if it occurs would, in addition to the measures above, require:

a.
A credible strategic force posture in Southeast Asia and elsewhere to meet the ChiCom threat.
b.
A suitable build-up in Thailand to enable the expeditious deployment there of major US forces. This build-up would include logistic support bases, new airfields, improvement of existing airbases to increase their capacity, improvements to LOCs, and measures to increase the readiness of the Thai armed forces.

Execution

19. (TS) The Joint Chiefs of Staff consider that, as a matter of principle, CINCPAC should be given as wide latitude as possible under the circumstances in executing the above measures in consonance with the forces, support, and general policy guidance provided to CINCPAC by the Joint Chiefs of Staff.
