In the course of the past year and a half the chances that the Communists would in South Vietnam by military victory have vanished. This is the clearest development of the period; in other respects the course of the struggle remains inconclusive. In Saigon the political health of the South Vietnamese Govern- ment is still precarious, though much better than it was a year ago. The program for pacification of the countryside has made some progress, but results continue to be spotty. The fighting capabilities of the South Vietnamese arty remain generally poor, and its eventual usefulness in pacification remains uncertain. The sympathies of much of the non-Communist world, and the efforts POPI/CDF 116649- GROUP I Excluded from automatic downgrading and declassification Approved For Release 2006/12/11 : CIA-RDP79R00904AO01300040041-1 Approved For Release 2006/12/11 : CIA-RDP79R00904A001300040041-1 of many non-Communist governments, are more concerned with stopping the war than with the terms for settlement. There is no evident dimunition of the Communist capability to continue the struggle. In any case, there is no evidence of a dimunition of Communist will to continue the war. 2. The matter of will is crucial. Hanoi's determination probably is strengthened by hopes that the US will lose heart if the struggle is prolonged and by its belief that South Vietnam cannot create a viable political structure capable of winning mass support. But the strains upon the Communist side are great. and are increasing. Above all, probally, the Communists face problems in recruiting manpower of goad quality within South Vietnam, and in preserving the morale of forces which have been disappointed of quick victory and must continue the struggle under increasingly difficult circumstances. 3. We do not know how long the Communists will remain determined to persist. There are some indications that they may be reviewing their strategy and pondering their prospects.

We see no good reason to believe that such a decision is likely in the near future, though it could happen with little prior warning. At present, we think the only safe estimate is that the struggle, if it is aimed at the creation of a peaceful South Vietnamese state which can stand on its own feet, will still be long and costly. k. In the following paragraphs we discuss various aspects of the situation in greater detail.

Certain trends, vihich were already apparent in late 1965, were confirmed during 196.6. The capability of the Com- munist main force to conduct offensive military rperation3 was blunted, while the US and Allied forces gradually gained the battlefield in.itiattve. Ccmmunist main force units were mauled time and again by the increasingly effective "search and destroy" tactics of the US command. Com_raunist preparations for major initiatives have been repeatedly spoiled by a. combilation of good fie,;, intelligence and quick response capabilities. Communist forces suffered heavy losses from the combined fire power of US artillery and tactical air support. 6. Nevertheless, the NVA/VC main forces remain in the field. During 1966 the total strength of these forces increased from about 83,000 to 106,400, largely because of the heavy input of men from the North. There is no reason to doubt that the present force level can be sustained if li not chooses. As far as materiel is concerned, capabilities for transporting supplies to the main forces have been more than adequate and well above requirements.

There is considerable evidence that the military developments of the past year have led the Communists to re- appraise their strategy and tactics. Probably because they now recognize that an outright military victory is impossible, they appear to be adjusting their military effort primarily with a view to sustaining a long war. Their objectives in the coming phase will probably be to achieve a more favorable ratio of attrition rates by avoiding large-scale battles in favor of numerous, widely dispersed small-unit actions, to harass and obstruct the US/GVN pacification program, to raise the cost of the bombing program, and, in general, to create an impression that real progress, let alone victory, is impossible for the US. Hanoi appears to believe, in the light of its reading of the American body politic, that American will to persist will not prove equal to a protracted and costly struggle. 8. The Role of the Main Forces. During the phase which the struggle is note entering, the Communists will almost certainly attempt to keep major elements of their main force, including the NVA elements, in the field.

Large-scale attacks will almost certainly be launched whenever conditions a;Tear to augur success, and especially when such an attack holds saiie promise of having an important political effect on the US. Sustained large-unit operations, however, seem likely to continue to diminish as the Communists seek to cut the rate of attrition on the main forces. This could mean that it will be more difficult for US forces to strike large enemy concentrations with "search and destroy" operations. 9. In order to accomplish these aims, it is not necessary for the main forces to expand greatly. It is possible that Hanoi plans to slot-r down the expansion of main force units, especially if there is to be greater emphasis on guerrilla tactics. This could result in a decline in the introduction of complete units of the North Vietnamese Army Into South Vietnam. There are some signs that this may already be taking place. Since l July no new units have been identified; hcnwwever, because of the time lag which often occurs between actual infiltration and confirmation by US intelligence, it is still too early to say that a decline Approved For Release 2006/12/11 : CIA-RDP79R00904AO01300040041-1 Approved For Release 2006/12/11 : CIA-RDP79R00904A001300040041-1 has occurred. In any event, North Vietnam will almost certainly have to send sizeable gr,:)aps of replacement personnel into the South in order to maintain existing NVA main force units at adequate strength. 10. The Role of the Guerrillas. The next year is likely to witness an increased emphasis on the guerrilla war. This war, of course, never ce,ed though it was conducted at a somewhat lower level this past year. Communist strategists apparently now believe that intensified guerrilla operations offer the best prospect of countering the impact of the US military buildup. The missions of the guerrilla forces will probably emphasize harrassment of the bases and LOC's of the US and ARVN forces in order to pin down these forces in defensive operations and, secondly, disruption of the pacification program by attacks on security forces assigned to RD, on RD cadres, and on pacified Hamlets. To achieve these goals, some VC main force units may be diverted to guerrilla operations, and the VC may make even more intensive efforts to motivate the population under its control. In addition, the Communists will almost certainly attempt further "spectaculars" such as the mortaring of major airfields and US Approved For Release 2006/12/11 : CIA-RDP79R00904A001300040041-1 Approved For Release 2006/12/11 : CIA-RDP79R00904A001300040041-1 supply depots. Such operations which involve relatively little risk, commit few assets and, if successful, achieve major political and propaganda effects. 11. The Communists will continue and probably step up what has been termed the "criminal" war of assassination and terrorism. In the provinces such activity has always been one of the Communists' principal means of attacking the local roots of central authority and of cowing the rural population. The recent assassination of Constituent Assembly member Tran Van Van and the attempt on Dr. PhFm Quang Dan suggests that the Ccmmunists may be embarking on an intensified campaign of urban terrorism. The initiation of such a campaign under present circumstances w would actually be more a sign of Communist weakness than of strength. (Ideally, urban assets would be saved for the final push to topple a government softened by military defeat.) The Communists may feel, however, that politically and psychologically they must compensate for battlefield reverses and, further, that by care- fully selecting their targets, they can exacerbate regional tensions within the Vietnamese body politic and fan already existing suspicion and hositility among contending non-Communist politicians and factions.

A VC effort to press the guerrilla war will pose a serious challenge for the allied forces, especially since the h of the irregulars may have been underestimated in the strenI/ past. For some years it has been estimated that there Caere about 100,000-120,000 irregulars, but there is now documentary evidence which strongly suggests that at the beginning of 1965, irregular strength was about 200,000 and that the goal for the end of 1965 was 250,000-300,000. More recent documentary evidence suggests that this goal was probably reached, at least during 1966. CommLvnis t Problems and Prospects 13. Man-rower. Though we may have erred in underestimating the size of the irregular force, this is not to say that the Communists are free of manpower problems. The heavy losses suffered by the Communist forces are a continuing burden, particularly for C the Viet Cong. Total losses for 1966 were about 120,000, including f Irregulars are divided into full-time guerrillas, part-time militia, and secret guerrillas who operate clandestinely. 2/ A statistical analysis of manpower problems is inhibited by serious deficiencies in the available data. The three vital measures of manpower are estimates of losses, the level of infiltration from the North, and the Order of Battle. The large areas of uncertainty which surround each of these key inputs mean that the judgments and estimates based on them rest on an inadequate factual underpinning and are thus subject to significant changes as more information is obtained. Nevertheless, the statistics do permit judgements on major trends.

Against its on losses of 30,000-35,000, however North Vietnam was able to sustain an input of about 75,000. And as noted above, the VC irregular force was probably expanding to 250,000-300,000, as well as making up for combat losses in its awn and in Viet Cong main force units. 14. During 1967, we estimate that the Viet Cong recruiting and training apparatus will be required to supply about 7,000- 10,000 personnel per month. The VC are capable of this effort, but it is probably close to their maximum capability. Of this total requirement about 3,000-4,000 will be earmarked for replace- ments in main force units. This can be done, but upgrading irregulars at this rate would probably mean a decline in the quality of re- placements sent to the Main Forces. The North Vietnamese, however, seem to have been more successful in meeting their manpower require- ments in 1966 then they were in 1965. 15. There is already evidence that competition for manpower was creating problems during 1966. A staff officer of the VC 5th division, for example, stated that his division was having difficulties in keeping up to strength because of lack of adequate Approved For Release 2006/12/11 : CIA-RDP79R00904AO01300040041-1 Approved For Release 2006/12/11 : CIA-RDP79R00904A001300040041-1 S-F-C-R-E-T replacements. The division was using North Vietnamese as re- placements, though one .?ould normally expect upgraded guerrillas and local draftees to be more than adequate as replacements for the VC Main Forces. A recently captured document also indicates that some hard-pressed guerrilla commanders were using subterfuge to prevent guerrillas from being assigned to main force units. 16. Morale. Morale is likely to be a more critical factor than in the past. We know that in general Viet Cong morale is less good than a year ago. The reasons include the defeats and harassments resulting from superior US firepower and mobility and good tactical intelligence; some -czar tiaeariness accentuated by the diminishing prospects of any foreseeable end to the par; the raan- power pinch which has forced, the VC to send recruits to main force units from their native Delta habitat into the inhospitable and disease infested highlands; food and medicine shortages. T?one of these manpower or morale problems is likely to be significantly alleviated in a protracted war, assuming US-ARVN and Korean forces maintain pressures on VC base areas and main force units.

There is bound to be some sense of a loss of momentum, which could have an important bearing on the attitudes of officers and cadres who were led to believe that victory was not far off. And perhaps i:;xr : ri;,there may be a psychological impact on the people. It can be fatal to a guerrilla movement or a revolutionary war if the people decide that the rebels may not in after all. But, as already noted, the Communist main forces no longer have the capability of gaining the kind of major tactical successes which would sustain their momentum. 18. To sum up the military outloo1,the focus of the Com- munist effort is likely to be more on small unit actions, terrorism, sabotage and those tactics i?7hich pose the most difficult challenge to the allied forces. As far, as capabilities and will are concerned, the Communists are encawtering growing problems, but none of these appear to be critical. Thus, from the purely military standpoint there are good reasons to believe that the Communists will persevere.

The political aspects of the war may now loom somewhat more important to the Communists as the military situation assumes more and more the character of a protracted and costly struggle. The Communist efforts of course, still depends to a great extent on the dedication and caamnitment of its cadres and their organi- zaticnsl. and military skills. But these would be of no avail with- out the active or enforced support of a substantial par', of the population. If this support could be denied, the VC would be highly vulnerable, and probably could be driven off into the hills to starve or slowly deteriorate in strength and morale, 20. The Communists lost ground in 1966 in terns of what they can offer the people. They are likely to lose even more ground in 1967. The development of a degree of stability in Saigon, the holding of elections, and the process of building national institu- tions began to provide the first credible political alternative since Diem. At the level of more particular and immediate concern to the villagers there was no decisive shift, but the strains on the VC apparatus and the pressure of US/ARVNmilitary, pacification, civic action, and economic and construction programs were beginning - 13 - Approved For Release 2006/12/11 : CIA-RDP79R00904A001300040041-1 Approved For Release 2006/12/11 : CIA-RDP79R00904A001300040041-1 S-E-C-R-E>T to tell in particular areas, if not generally throughout South Vietnam. The VC have been driven increasingly to treat the population more harshly. Increased taxation, forced recruitment, and less selective acts of terrorism have hurt their image as defenders of the people. And association with the VC seems in- creasingly the wrong path to what the villagers want most of all. -- peace and security. 21. The VC ability to defend villages against US/ARVN attacks has decl:Uied, and it has become increasingly likely that the presence of VC forces in a village will bring down a rain of bombs and g afire. In contrast, in government-controlled areas schools are being built, medical assistance is available, economic activity is possible, there is a degree of iunuunity from bombings and battles, and the sheer weight of the resources available -- trucks, earthniovers, airplanes -- suggests that this may be the winning side. There are, of course, many shortcomings on the government side, including the pervasive threat of terrorism against those who go over or take active roles.

Pacification. The Communists recognize the critical importance of defeating the pacification program. Over the next years they will probably attempt to roll back the program just as they rolled up Diem's strategic hamlets in 1963 when these began to threaten the VC grip on some parts of the countryside. The pactfication program depends on many factors., not the least of which is the steady commitment of the Saigon Government. But in the near term., the key factor probably is going to be the protection of pacified areas. And this rests to a considerable degree on the AWN and the Regional and Popular force troops. 23. The Role of ARIN. The ARVPT today is not in good shape. In general, its morale is poor, and its training has improved little. Only 4 of its 11 divisions are capable of reasonable performance in cctnbat. This is primarily because of the wide diversity in the qualities of division level leadership. - 15 - Approved For Release 2006/12/11 : CIA-RDP79R00904A001300040041-1 Approved For Release 2006/12/11 : CIA-RDP79R00904A001300040041-1 S-E-C-R-E-T 24.

With Soviet and Chinese assistance, Hanoi has already built up its air defense step by step: conventional AAA, SANIs, MIGs, then more advanced MdGs, air-to-air missiles, improved radars, integrated warning systems with China, and finally, North Korean pilots have appeared. We cannot exclude that as the next step to check the US bombing, the Vietnamese will begin to use Communist "volunteers" in combat, the North Koreans being the first test of US reactions. 29. It is not demonstrable that the bombing of North Viet- nam has thus far zeakened Hanoi's zzill to continue the var. There appears to be confidence that North Vietnam can live v ith the present types and scale of attack and can also increase the attackers' losses. The principal economic cost to Hanoi has been the diversion of manpower, although me estimate that the diversion reached its -peak in late 1965, and may now be declining. Losses to the economy are almost certainly vieti zed by Hanoi's 19 - Approved For Release 2006/12/11 : CIA-RDP79R00904A001300040041-1 Approved For Release 2006/12/11 : CIA-RDP79R00904A001300040041-1 ,-" S-E-C-R-E-T leaders as tolerable given what is at stake in the war. The bombing of infiltration routes has not resulted in shortages of materiel for the forces in South Vietnam, or significantly reduced Hanoi's ability to maintain logistic support of these forces. It seems clear now that the air campaign by itself cannot persuade Hanoi to abandon the war. Other factors would neigh much more heavily in the North Vietnamese leaders' appraisal of the prospects of victory and therefore in influencing persist. DO. Hanoi has even seen political advantage in the bombing campaign. Together Z rith its allies and supporters it has used the bombing to discredit the whole US effort in Vietnam. The propaganda to maximize international pressure on the US to desist from bombing is no doubt seen as a means of persuading the US to alter is war aims. There is no persuasive evidence at this time that a halt to the bombing t could produce a Communist move for a truce and negotiations. Other considerations would figure more importantly, in particular the Communist judgment as to likely political developments in the wake of a truce.

The option of trying for a favorable political settle- ment through negotiations is probably given periodic consideration in Hanoi. That it has been rejected so far has probably been due, at least in part, to a deep suspicion of the entire concept of achieving Hanoi's ends through political bargaining -- a suspicion well grounded in what the North Vietnamese must regard as the sell- out of their interests in 1954. Moreover, their revolutionary mystique impels them toward a decisive victory won through their own military in the field rather than a qualified victory won at the conference table with the help of other powers. Though they probably recognize that a decisive victory is not aoi,- in sight, they probably still hope that persistence in a protracted war will bring the US to withdraw or consent to a settlement clearly advantageous to Hanoi. 32. The only other circumstances in which Hanoi seems likely to negotiate would be those in which it came to believe that its aims in South Vietnam were actually being prejudiced by continued war and. that a negotiated political arrangement offered a chance to preserve its assets there, for use in a purely political Approved For Release 2006/12/11 : CIA-RDP79R00904A001300040041-1 Approved For Release 2006/12/11 : CIA-RDP79R00904AO01300040041-1 711 S-E-C-R-E-T struggle or in a new revolutionary attempt later. At present there is no clear indication that such a turning in Hanoi's attitude is in the offing, but this could come at any time and we would be unlikely to have advanced indications of it in any case. 33. Another factor bearing on the issue of negotiations is the influence of Hanoi's allies. The argument is often made that Moscow will eventually persuade Hanoi to settle the war, in order to remove Vietnam from the international agenda and get on with the business of liquidating the cold war. In fact, the Soviet attitude toward the va.r appears to be mixed. The Soviets can see certain advantages in the problems which the war generates for US policy, especially in Europe. On the other hard, they are aware that the situation carries risks of direct confrontation with the US, which they wish to avoid. For the Soviets, the optimum outcome would be one in which a political process, perhaps including negotiation, gave Hanoi a good prospect of achieving its aims in South Vietnam; this would inflict a major reverse on the US and would win credit for the USSR in the international Communist movement, perhaps even to the detriment of Peking.

China's adamant stand against any negotiations has been one of the constant factors in the war, and it seems likely that Peking will continue to reject a political settlement and urge a continuation of the fighting. But we cannot ignore the momentous developments in Peking and the possibility that in the next year or two great changes may occur in the leadership. It does not seem likely that a future Chinese regime, following after Mao, will see its interests in Vietnam and Southeast Asia in a radically different way. But it is possible that the demise of Mao would bring important reappraisals, which almost certainly would have to include the Vietnamese question. Conclusion 35. We conclude not only that the Communists are capable of fighting on for at least another year, but that they are probably determined to do so. In our view, however, they face important problems, and we believe that the Communist position, both militarily and politically in South Vietnam, will deteriorate Approved For Release 2006/12/11 : CIA-RDP79R00904AO01300040041-1 Approved For Release 2006/12/11 : CIA-RDP79R00904A001300040041-1 S-E-C-R-E-T further over the next year.
