94. Information Memorandum From the Acting Deputy Under Secretary of State for Political Affairs (Thompson) to Secretary of State Rusk1

SUBJECT

  • China Study
1.
Pursuant to your request I have proceeded with the arrangements for a meeting on the above subject. The exact date is not yet settled because of uncertainties and conflicts in the schedules of the senior participants in the meeting but I expect that a mutually satisfactory date can be set after Secretary McNamara returns from Viet Nam. In addition to yourself, the Secretary of Defense, and Mac Bundy, I have alerted Bus Wheeler and Cy Vance (who together with me formed the Board of Directors for the China Study), Bill Bundy and John McNaughton.
2.
I have also made available to Defense and to Mac Bundy a list of “Critical Policy Problems” (Attachment A), a resume of the China Study (Attachment B), and a precis of the views which we received from Kohler, Reischauer, Rice and Taylor/Johnson (Attachment C).2
3.
You may find it useful, as a means of orienting the discussion, to establish at the outset the purpose for convening the meeting. In this connection, I see the following objectives:

A. A Discussion of the “Critical Policy Problems.”

It appears to me that these issues are intrinsically of great significance and to the extent that they are deemed valid, it would be extremely useful to have both an understanding of their nature and a consensus about their significance at the top levels of the government. My own impression, I am bound to make clear, is that both field comments and the study itself seem to suggest that further escalation of our military operations against the DRV (as opposed to prosecuting the war in the RVN) would not have the result of winning the war in which we are presently engaged but would seriously risk changing the character of the war, possibly to the point where the costs are out of proportion to the gains. By and large, it seems to me that the comments on the study which we have received from key U.S. Missions abroad have indicated a preference for the thesis that “the war must be won in the South.” Obviously, this issue has been through the crucible of debate many times but perhaps not with the advantage of the “look down the road” which is furnished by the Study Group’s report.

B. Discussion of Next Steps.

(1)

Long Range Study.

The short range study laid no claims to being a definitive analysis of the problem, nor does it purport to represent a plan of action for the future. We are, of course, committed to undertake a longer range study, in which State will take a leading role, of US-Chinese relations looking through 1975. You may wish to solicit views as to areas of investigation which that study might seek to analyze.

(2)

Short Range Politico-Military Planning.

It was my feeling in initiating the China Study that pressures inevitably force too much of a concentration on very immediate objectives and courses of action without permitting the full recognition of longer range implications and without necessarily permitting a relating of individual actions to a comprehensive, long-range politico-military concept. A rather provocative, but trenchant, observation made in the Report epitomizes the concern I think we all share: [Page 185]

“With or without a decision on our part to increase the level of such military pressure, the history of past conflicts worldwide suggests that there is some danger that punitive military operations may acquire a momentum of their own and may be allowed to continue beyond the point of any real military or political utility.”

To the extent that the discussion of the study, and more specifically, consideration of the “Critical Policy Problems” and the comments from the Missions identify points which you, the Secretary of Defense and Mac Bundy deem to be significant, you may wish to suggest that these points be taken into account in our current and continuing Southeast Asia politico-military planning.

CRITICAL POLICY PROBLEMS

1. Degree of Soviet Involvement.

With respect to Soviet interests in Southeast Asia, it has been pointed out that the Chinese did not invent nor have they been in the past the principal supporters of the doctrine of national liberation. The Soviets are equally committed to the concept of wars of national liberation.

The study however appears to underestimate the degree of Soviet involvement and of Soviet reaction to U.S. actions, particularly in the stage where U.S. military operations are confined to the DRV, and consequently overestimates the possibility of reaching a tacit understanding between the U.S. and USSR to avoid a major conflict as each side seeks to defend its own interests. Because of the public commitment which the USSR has made to defend the interests of North Viet Nam, escalation or even continuation of our attacks on North Viet Nam will make it increasingly difficult to maintain any serious dialogue with the USSR for the purpose of trying to influence it to moderate its support of that regime. Moreover, the type of assistance which Moscow has already supplied Hanoi could lead to a confrontation with the United States. As the amount of equipment increases, the possibility of mutual miscalculation or accident also increases.

[Page 186]

In general, the assumption that Soviet involvement would be minimal has the effect of making the military equation less difficult for the U.S. If a major Soviet involvement of materiel and perhaps of volunteers was in prospect, the effect this would have on the size, nature and consequences of the U.S. commitment, is a matter not explored by the study.

With respect to U.S. actions against Communist China, the study does say that “in the event of U.S. attacks against South China, the USSR would probably feel compelled to provide the ChiComs, after some period of delay, with military equipment, e.g., advanced fighters and missiles.” “Soviet first line aircraft and SAMs might have a critical effect on control of the air over the DRV and China.” A threat to the existence of a Communist regime in Peiping would probably force the Soviets to become involved militarily to a highly dangerous degree: “An objective that includes the destruction of the Communist regime in China would be most costly and would carry grave risks of general war with the USSR.” This would illustrate a situation in which military activities would have far out-run fundamental U.S. national security interests.

2. The Nature of the Communist Chinese Threat.

While the Chinese are utterly opposed to the U.S. presence in Southeast Asia, they expect to use subversion and infiltration of supplies to achieve their objectives, and not direct military force unless their own immediate lines of defense are threatened. The study does not indicate what, if any, level and intensification of U.S. military operations in North Viet Nam will bring the Chinese into the war but it does indicate that at some point Chinese interests and prestige will become increasingly committed to some sort of participation. It has been suggested that the Communist Chinese might become actively involved in the war if the Communist regime in North Viet Nam were threatened, if Chinese borders were placed in jeopardy, or if large Chinese Nationalist forces were brought to the Southeast Asia mainland.

One form of Chinese intervention, well prior to any land action, might be the commitment of fighters from Chinese bases to the air defense of the DRV. The Study suggests that the U.S. would be at a serious disadvantage if it failed to neutralize bases from which the Chinese fighters were employed. It is hard to believe that such an attack on China could result in anything other than the signal for war with that country. Indeed, a special NIE recently completed estimates that if the Chinese actually commit their aircraft to defend the DRV from Chinese bases they must be assumed to be prepared to fight a major conflict with the U.S. Already we have reports that the Chinese are evacuating various executive offices and factories from certain cities and are also installing large numbers of AA units in key areas apparently in anticipation of an escalation of conflict to the Chinese mainland.

[Page 187]

3. The Use of Nuclear Weapons.

The study suggests that military requirements for nuclear weapons will be especially acute in two circumstances: (1) if the ChiComs/DRV launched a massive invasion of Southeast Asia before U.S. forces were deployed there in large numbers; (“It is quite likely that the U.S. would be faced with the decision to use nuclear weapons … perhaps the second or third day of the invasion.”) (2) if the U.S. were to bombard Communist Chinese military or industrial facilities on any military significant scale; (“The comparable effects of a conventional attack are very much less because the time required to achieve the same level of destruction is very much longer, thus, permitting repair of damage …”). There is an inference in the study that planners are also counting heavily on the psychological effects of nuclear weapons to break the ChiCom will to resist. However, the report emphasizes that the use of nuclear weapons by the U.S. would produce an “overwhelmingly adverse reaction from U.S. allies as well as the Communist world and the uncommitted powers” and that “lasting resentment against the U.S. might be generated.” It is suggested that U.S. use of nuclear weapons might mean the loss of key military bases in the Far East, the disassociation of NATO countries from U.S. actions in Asia, and the reduction or termination of the U.S. presence in many parts of the non-aligned world.

While it seems highly improbable that the Soviets would turn over nuclear weapons to the Chinese, and at least in the relatively short run the Chinese will not have an inventory of their own, it is not quite so inconceivable that the Soviets might support the Chinese with their own nuclear arsenal by some expedient method. Though this would obviously be very dangerous for the Soviets, they might feel forced to it, and might even devise techniques which were sufficiently ambiguous, such as provision of Soviet volunteers with nuclear capability, which the Soviets might calculate would avoid a direct confrontation with the U.S. In any event, if the enemy did have nuclear weapons for use in the theater, for example, against U.S. and allied bases and forces, is it entirely clear that introduction of nuclear weapons would even be militarily advantageous to the U.S.?

4. Escalation of Political Objectives.

The study lays considerable stress on the upward pressure on U.S. objectives which would result from a major military confrontation with Communist China (e.g., “initial U.S. objectives … would appear wholly inadequate to the large-scale hostilities going on and some adjustment would have to be made.”) One objective which is frequently mentioned is the reunification of Viet Nam. Others mentioned are the destruction of ChiCom nuclear facilities, the ChiCom industrial base, and even the elimination of the Communist regime in Peiping. “But enlarged objectives also mean enlarged costs, and perhaps a war in Asia which might be [Page 188] decisive only when large-scale strategic nuclear attacks against China were carried out.” Since military domination of China by the U.S. seems impractical in military terms, would almost assuredly involve war with the Soviet Union, and seems otherwise to present enormous problems for the U.S., consideration should be given to such questions as how readily we should be prepared to expand political objectives, how insistent we should be on maintaining limited objectives in the face of major hostilities, and whether, in fact, we should not insure that military operations do not create an undesired upward pressure on national objectives.

RESUME

The China confrontation study was undertaken on March 8 under the direct supervision of Mr. Vance, General Wheeler and Ambassador Thompson. It was completed on April 30. The staff work was done by a State/DOD/JCS team under the direction of Lt. General Spivy, newly appointed head of J–5. The study is largely focused on the military implications of a rising crescendo of hostilities with the Red Chinese, the scenarios in some cases being intentionally forced in order to bring out the aforementioned military implications.

The study assumes that the broad political objective of the US in the Far East is to seek the containment of Communist China, working over the longer run and as occasion permits for a softening of the present militant approach of the Chinese Communist leadership. Within this broad framework, the group examined the more immediate and specific political objectives which the US might wish to pursue, assuming that under alternative potential contingency situations the US could find itself faced with the possibility of a military confrontation with Communist China. The study was to examine these political objectives in relation to existing and projected military plans and capabilities. Points of particular concern were to be how to discourage Soviet support for the ChiComs in event of hostilities; how to keep the level of hostilities as low as possible consistent with attainment of objectives; the proper role for our nuclear capability; and what political and military adjustments were indicated by the study.

Essentially the study moves through five basic military situations, starting from the position in which we found ourselves in Southeast Asia in March 1965, through a major nuclear war with the Chinese.

[Page 189]
  • In Situation A, US air attacks (2500 sorties) on military targets well removed from urban industrial areas have not produced the results we desire. A number of military installations have been destroyed or damaged; about 20% of the DRV’s ammunition storage capacity has been destroyed; and the movement of supplies south of the 20th parallel has been restricted. Despite this limited impact, the bombings have had a cohesive effect on the populace of North Vietnam and there has been no significant reduction in DRV supply and support of the continuing Vietnam operations. Therefore, the US elects to increase the scale and scope of bombing within North Vietnam, to include peripheral industrial targets, such as selected electric power plants.
  • Situation B represents one step up the ladder of escalation. At this point, a total of 4500 sorties have been flown by US/RVN forces which include the increase in scale and scope as a result of Situation A. However, the Viet Cong have intensified their activity and expanded their control despite the increased bombing; ChiCom volunteers are now operating in North Vietnam with limited numbers of aircraft (50–70) and surface to air missiles; and Soviet missile technicians have manned the SA–2 SAM installation in the vicinity of Hanoi. The US response is to increase the level of bombing again, including more general attack of industrial targets and all categories of transportation, but excluding Hanoi; deploy to South Vietnam the remainder of the Marine division which has elements already there, one Army Division, and one Free World Division (presumed to be ROK); and develop plans and prepare to blockade North Vietnam.
  • In Situation C, the US response described in Situation B has checked deterioration of the military and political situation in South Vietnam and the DRV gives some indications of wavering. At this point, ChiCom aircraft operating from bases in Hainan and South China engage the US/GVN aircraft which are bombing North Vietnam, and large numbers of ChiCom ground forces are deployed in North Vietnam. The USSR has continued to send “volunteer” units to set up and man missile sites. It has announced also the forming of a “volunteer” division which it implies will be sent to North Vietnam if the US does not halt aggression and agree to negotiations.

The postulated US response in Situation C is to: increase military activity against the Viet Cong; include targets in Hanoi in air attacks; bomb ChiCom air and naval bases on Hainan Island and in South China, as well as the DRV ports; and mine ports of DRV, in South China, and on Hainan. Additional naval units are introduced into the South China Sea and two Army divisions are deployed to Thailand.

The marked improvement in South Vietnam assumed to have been produced by the measures taken by the US in Situation C, causes Communist China and the DRV in Situation D to launch a major attack at the [Page 190] beginning of the dry season. This involves operations by 22 divisions in South Vietnam, Laos and Thailand. Rather than postulating a US response in this situation, the study examined the political and military implications of a variety of courses of action.

The final situation (Alternative Situation A) departs from the forced escalation of Situation A through D by assuming ChiCom/DRV initiation of large scale ground attack prior to the significant build-up of friendly forces which is assumed had been achieved in Situation D as by-product of progressive escalation. Thus the situation when the attack commences is assumed to be that at the outset of the study, i.e., Situation A. The treatment in Alternative Situation A generally parallels that in Situation D: an examination of the political and military implications of a variety of courses of action.

Both Situation D and Alternative Situation A include assessment of the impact of nuclear weapons on ground and air operations. Some interesting comparisons of nuclear and non-nuclear force requirements for the same operations appear in summary charts opposite pp IV–60 and IV–80.4
