DISCUSSION "

I. NATURE OF THE

The Communists have been struggling to win control of Indo-Chlna ever since the Indo-Chinese Communist Party was organized Ina. This struggle has pawed through several stages,operations against the Japanese In the later years o( World War IIajor aar against the French. After the French withdrawal, the CommunlsU were apparently confident that the South (Vietnamese' Government (GVN) wouldr that in any event, the nationwide elections called for In the Genoa Accords mould scon deliver all of Vietnam Into their hands. Although guerrilla bands were lelt behind when the country washe Communists did not engage In armed operations against the GVN, but attempted to undermine It by other means. Contrary torupee la tlons, however, the GVN, under President Ngom, not only survived lut developed sufficient strength, partlycnsequence of Western political and economic support, to enable It to Ignore6 election deadline and to make appreciable progress.

These developments confronted the Vietnamese CommunlsUew situation. They had developed substantial ground forces In North Vietnam, but South Vietnam also, with US assistance, had substantially Improved Its military capabilities. Open Invasion, therefore, could notalk-In, and In any rase the strong US commitment, nol only to South Vietnam but toahoie. madeourse aa undesirable one. The Vietnamese Communists thereupon resumed guerrilla warfare combined with Intensified terrorism, subversion, and enticement They evidently concluded lhat, by winning converts and sympathisers In the countryside, by depriving the government ofcontrol, and by causing loss of moraleill within the govern* i- icadres, they would pave the wayinal political victory.

With Diem's consolidation of his personal control over theand the military establlshroent, he became Increasingly reluctant to delegate authority or take other measures to Improve the efficiency and morale of the military and civil services. Close operational control from Saigon not only generated serious discontent within aM levels of the government but also Inhibited the effectiveness of government actions, particularly in the countryside. The launchingull-scale Communist Insurgency Ininally led the Diem regime, partly out of necessity and partlyesult of the substantially increased US commitment to South Vietnam, to Initiate broad pleasures to rectify these conditions.

Tne Communist effort In South Vietnam Is essentially one ofsubversion In which extensive military acUvlty presently plays the predominant role The primary aim of the Communists Is to secure the support of the ruralbuttressed, where possible, by positive loyalty. By various forms of military and terrorist action, they endeavor to cow the recalcitrant, demonstrate that Ihf government cannot protect Its adherents, andeneral atmosphere ofThey also endeavor to weaken the government's poslUon In the countryside by assassinating Its officials, defeating its forces,the morale of Its cadres and supporters and. generally, tarnishing Its image In every way possible.

It was regarded asmilitary problem lo be dealt with by military means. These views have become modifiedonsequence of the progress of events andonsequence of US effort to convince the regime to regard the conflict In broader perspective. During the" past yrrralf, the government has begun to see the conflict as an Internal one requiring socio-political as veil as military measures and to view the nilitary problem as one requiring grrater flrxibllity In deployment and tactics. Government recognition of these factors has resulted in the development, with US assistance,omprehensive counterfnsurgency strategy.

IV. PROGRfSS AND PROSPECTS

Current Military Situation Although there Is no satisfactory objective means of detei mining how the war ts going, we bclirve that-all factors considered--Communist progress has been bluntrd and the situation istrengthened South Vietnamese capabilities and efTcctlvrnru. and particularly US involvemrnt, are causing the Viet Cong Incrru'ted difficulty. There are some Indications that the Viet Cong are suffering from local shortages of suppliesecline in morale. There have been few desertions by Viet Cong regularbut there has been some increase In dcierUonj from the Vict Cong militia and guerrilla forces Although statistics of casualties and figures on the numbers of villages under government control are not very reliable or very helpfulreater degree of security In the countryside has apparently been achieved and the government's control of Imrorlant population areas has expanded someahal during the past several months.

There arc as yet no persuasive indications, however, that the Viet Cong have been grievously hurl. They continue to operate ln most sections of SouJh.Vielnoin. and much of the countryside remains in thelx^lihiidi Although the number of Viet Cong lncldrnts andIs2 levels, it it', number has increased In the past few weeks. Government military capabilities have increased markedlythe past year, but so have those of the Viet Cong.

omtnvnlit Intentions. The magnitude of the US commitmenteffectiveness of the South Vietnamese counterln-surgency effort err almost certainly causing Hanoi and Its Viet Cong subordinates Increasing concern. Although we believe that the Com-

jrmunlsts have tn no wsy relaxed their determination to win control of South Vietnam, they must realise that their task is becomingdifficult, and they may be reappraising their general policy. We believe It unlikely, especially in viev of the open US commitment, that the North Vietnamese regime will either resort to overt military attach or introduce acknowledged North Vietnamese military units into the south in an effort touick victory.

SO. For the present, at least, we believe that the Communists will continue toar of attrition, hoping for some break in the situation which willo victory. They must be aware, for example, Of tht disaflecUon engendered by the political methods of the regime, and they are probably also aware of the dissatisfaction among many Americans over the policies and practices of the OVN. They probably hope for political deterloralion which will make their task easier, or that the US will tire of costly and frustrating guenllli warfare and accept some facesaving way out At some point the Communists mighterious elTori to convene an international conference toUie neutralisation of South Vietnam.

ny nonCommunlsl coup effort would probably be regarded as providing an opportunity for exploitation. We believe that at present the Communists have neither the capability themselves to lead acoup d't'tat nor the ties with the non-Communist opposition which would enable them to participateoupNevertheless, they might be able In an tnstable situationfromuccessful or unsuccessful coup to gain somestrategic position In any event, the Communists evidently hopeombination of military pressure and political deterioration will lr. time create favorable circumstances either foroup de prcce orolitical aclUrmenl. say on the model of Laos, which would enable them to continue the struggle on more favorable terms.

S2hether the Communists are correct in theirwfll. ofdepend In some measure upon the extent and nature of US Involvement, but primarily upon the South Vietnamese response to the developing situation. We do not believe that lt lsat this time to project the future course of the war with any confidence. Despite OVN progress, the situation remainseries of major Vict Cong successes, ahould they occur, mighthattering psychological effect. Nevertheless, the heavy USand close working relationships between US and Vietnamesehave fundamentally altered the outlook. Changes andhave occurred during the past year which for Uie first time

c

indicate that the Viet Cong can be contain- -'Uiariiy and thatprogress can be made ln expandingovernment control and in creating greater security In therver, some areas Of Viet Cong control, such as the Mekong delu. will be very difficult to pacify, decisive campaigns have yet lo be fought, and no quick and easy end to the war Ir In sight

W. Developments In the ltst year or two have also gone someInasis for winning over the peasantry and In improving the efficiency of the military establishment and the civilian bureaucracy. It can, of course, be argued thatighly centrslued regime, stngir-mindedly dedicated to Independence, andeavy emphasis on personal loyalty can cope with the problems of guerrilla warfare. However, we believe thstgreater willingness on the part of the regime to enlist the active support of those who have becomeor discouraged ln the face ol DJcm's technique* of government would considerably speed tbe reduction of the Viet Cong Insurgency.
