318. Memorandum From the Assistant Secretary of Defense for Systems Analysis (Enthoven) to Secretary of Defense McNamara1

SUBJECT

  • Need for Better Reports on Thailand

The attached staff study of recent developments in Thailand was prepared on the basis of readily available documents and discussions with staff officers in ISA, DIA, and the State Department.

The paper indicates that events in Thailand are moving rapidly, rates of insurgency have sharply increased, Thai utilization of MAP equipment has improved, the Thais are anxious for U.S. advice and materiel assistance while retaining their desire to solve their own internal problems. It further states that the basic reports to Washington need to be expanded to permit a better and more current assessment of the developing situation.

The attached memorandum for the Chairman of the Joint Chiefs of Staff requests expanded reports on insurgent and counterinsurgent operations in Thailand, on Thai military performance, and on the performance of U.S. assistance programs. It will also request assessments of insurgent threat to U.S. bases in Thailand, U.S./Thai military dependence on the AID/Thai rural police program, the implications of moving U.S. troops into Thailand under current contingency plans, and the implications of losing U.S. bases in Thailand.

I recommend signature on the attached memorandum. OASD(ISA) concurs.2

DEVELOPMENTS IN THAILAND

The Threat

Communist infiltration and activity in Thailand are accelerating and will probably expand further in geographic scope and intensity over the next year or two. This deterioration in the security situation commenced in mid-1965. In part, it is due to increased U.S. activity in Laos and North Vietnam conducted from bases in Thailand. Rather complete “safe haven” training facilities have been located. Incidents in Northeast Thailand in the first five months of 1966 are greater than the total for all of 1965. Terrorism and ambush are employed; officials, school teachers and government informants are the principal targets. Estimates of 750 incidents of all kinds from January 1–May 30, 1966 are reported, including about 200 fatalities. (Regrettably, the availability of structured incident statistics at the Washington level is weak.) Available evidence indicates that during May the conflict between the RTG and the insurgents resulted in at least 12 armed clashes, more than 40 casualties, and discovery of at least 6 more communist camps. During the first four months of 1966, RTG security operations captured 219 communists and induced 903 more to surrender.

Even more important than the outbreak of incidents is the central point that between 500 and 1000 armed insurgents have free access to the rural populations and have begun to develop an organization and base of support for their activities against the government.

Discussions with staff officers in the concerned agencies reveal agreement that insurgent activity in Thailand is definitely increasing and is serious. Clearly, increased subversion activity in areas adjacent to U.S. air bases at Takli, Ubon, Udorn and Korat is cause for concern since these facilities are vulnerable.

The acceleration of communist and RTG operations requires that the structure and content of basic reports to Washington be improved to enable interested agencies to better follow and assess the rapidly developing situation.

The Thai Response

Available evidence from State, DOD, and CIA sources indicates that the Thai are becoming concerned with the threat and are groping for [Page 692] ways to attack the problem. MACTHAI and USOM consider recent evidence of RTG concern in their respective spheres of interest to be “dramatic.” The Thai leadership elite is united under the leadership of Marshal Thanom, and the key operating figure, General Praphat (Deputy Prime Minister, Minister of Interior, and Commander-in-Chief of the Army) has personally assumed command of all communist suppression operations in Thailand. Further evidence of their concern is the record of Thai accomplishments reported in the last six months. Their achievements include exceeding the USAF standard utilization rates for certain aircraft while flying counterinsurgency support missions; exceeding 6 months ahead of schedule the agreed manning levels for Thai Army troop units in Project 22 (a U.S. initiated joint program); increasing total Thai Army troop strength from 83,840 on May 1, 1966, to 96,000 by June 30 (with plans to reach 103,000 by the end of CY 1966); and increasing the defense budget by 27% for this fiscal year, with an additional 20% predicted in the next fiscal year. Above all, the Thai wish to minimize the involvement and presence of U.S. personnel, an attitude which can be quite advantageous to us.

The Thai Contribution

Aside from reacting to the immediate internal threat, the Thai have contributed without publicity to U.S. objectives in Southeast Asia in the following ways:

1.
Acceding without delay to every U.S. request to deploy USAF and Army units to Thailand, even at the cost of physical displacement from their own bases.
2.
Accepting almost all U.S. recommendations for construction of military facilities to meet U.S. needs.
3.
Approving every U.S. request for assistance on highly classified operations.
4.
Ignoring, until recently, the absence of a Status of Forces Agreement covering U.S. troops, despite the fact that every other major Asian ally of the U.S. has demanded one.
5.
Loaning aircraft and bombs from limited Thai war reserves to meet U.S. emergency needs on Laos.
6.
Providing pilots to fly T–28 missions in Laos.
7.
Committing an artillery and infantry screen of 300 troops (still there) to Laos who fought with distinction in checking the Pathet Lao.
8.
Providing cadre for most of the intelligence teams now operating in enemy-held sections of Laos and North Vietnam.
9.
Agreeing to keep their unit in Korea to preserve the image of a United Nations Force.

Lack of U.S. resolve in supporting the Thai in ways the Thai consider meaningful could eliminate assets of this type, and hurt U.S. policy and operations in Southeast Asia. We should not force the Thai to “blackmail” the U.S. or increase the strain in the relationship.

The U.S. Side

On a long term basis, the U.S. has undertaken clear commitments to support the Thai. These commitments extend across the Eisenhower, Kennedy and Johnson Administrations and have been progressively strengthened. It has been consistent U.S. policy to encourage the Thai to devote their resources to economic and social development, and to minimize military programs. They have done so, which is unusual for a military-dominated government, however enlightened.

The U.S. response to the recent Thai insurgency threat has been ambiguous. In view of the evidence at hand, the reasons for this ambiguity are difficult to understand (there is an unusual degree of unanimity at the staff officer level in every concerned agency that the threat is real, the Thai response to U.S. recommendations has been good, and the requests for help reasonable). The U.S. reluctance to respond is in part based on dissatisfaction with past performance by the Thai, and a belief that the Thai have not taken the effective actions to counter the insurgency that are within their resources and capability. These factors were evident in the U.S. delay in granting the Thai request for temporary helicopter augmentation. The Thai were disturbed by the slow U.S. response to what they considered an urgent and legitimate request from an ally in need.

There have been delays in the delivery of committed MAP items, and in supplying USOM police advisors. A brief review of the MAP program, with specific reference to the delivery situation, indicates that fair grounds do exist for the Ambassadorʼs assessment of May 24, 1966, when he pointed to “the rather shockingly poor United States record on the military assistance side.” Even when a policy decision is made in Washington to undertake a program, it is not necessarily carried out automatically, and there is no follow-up to ensure implementation. OSD might profitably consider some inquiry into the latter question.

The nature of the relationship between DOD and AID programs pertaining to rural security in Thailand is also hazy. The Thai have taken some limited steps to organize civil, military and police elements into an effective, unified counterinsurgency effort. Coordination of U.S. performance in assisting this effort is uneven, considering the separate and distinct AID, USIA and DOD programs.

Conclusions

It is difficult to understand why the U.S. does not have a coordinated counterinsurgency plan for Thailand, especially in view of the clear determination of the Thai to do the counterinsurgency job themselves with minimal involvement of U.S. personnel. In view of our commitments to the Thai, a clear determination of the U.S. position is essential.
