B. Focton Influencing Hanoi's Policy Decisions

Political leadership in North Vietnam is stable, cohesive, and unchallenged. From time lo time, however, there are indications of public and privatu debate within tliehierarchy over basicarge-scale military attacks versus guerrilla warfare tactics, teconstniction of tbe North versus liberation of the Soutli, and emphasis ontactics versus military action. Even though rivalries and policy disputes may exist within the collcgial apparatus that has ruled since Ho Chieath, they are maskedublic display of unity and an apparentof the Politburo membersall in line once decisions are made.3

In weighing the military factors, one dear coochnion emerges: thenly slightly in favor of tbe CVN.

On the other hand, Ihe political balance is clearly in the GVN's favor and will remain so. The communist infrastructure is still weakesult of the devastating losses ofS offensive and subsequent government pacification campaigns, although there have been some improvements in the infrastructure tn atew areas. Hard intelligence on the VCI is limited, but thereenerally negative cast in reports on its status, at least to the extent of strongly suggesting lhat the rebuilding effort svill take time. Tlie most serious problem of the VCI is ils inability to maintain close contact with the population. This is most apparent in urban areas, but even in tbe countryside, comnsmist access is limited.

Unlike past years, however, there was no subsequent announcement of military aid fiom the USSR, although military aid was mentioned after Le Duan's visit to Peking. North Vietnamese public statements (al-though not the most reliable wcathervane) seem to indicate lessatisfactory

But in view of Hanoi's sizable militarysuch reluctance on the pari of its allies would have niOre impact in political terms than on Hanoi's military capabilities in the short run.

Judgments about the potential US reactionajor military effort by the communists wouldajor factor in Hanoi's policyarge-scale offensive wouldotal rupture of the Parisand, as such, would remove itson active American involvement. Hanoi undoubtedly views the chances of American forces reentering the war under anyus greatly reduced due to domestic political pressures. In addition, if Hanoithe US as being preoccupied withtorolonged Arab-Israeli conflict, it might calculate that the US would befrom respondingajor communist provocation in Vietnam. But the Northleaders would not dismiss theof an American reaction, in partthey have been so wrong before in gauging the impact of American politics on the war. While the "stick" of American air power would be carefully considered before deciding whether to launch an offensive, the "carrot" of American dollars would represent no moroinor factor in Hanoi's policy calculations.

Catnhitdia. Communist action inis not likely to provide clear indications of Hanoi's intentions in Soulh Vietnam since there are uncertainties about how muchtho North Vietnamese have over the Khmer insurgents. In addition.elatively low scale ofin the Cambodian quadrant would not necessarily mean that Hanoi hod decided to lie low in South Vietnam. Indeed, the North Vietnamese might not want to tip their hand hy striking out hard in Cambodia if they were contemplating maior action in South Vietnam. Conversely, prior to launching an offensive in South Vietnam, Hanoi might want to wrap up the Caiulmdian situation toore accurate indication at lower cost of how the US might react to stepped-up communist action.

Hanoi already enjoys the access it needs to the eastern Cambodianulong the South Vietnamese bolder, and the cessation of US bombing has removed most of the danger of using thisommunist controlled Cambod ia, ho we vcr, could ease communist logistical burdens by opening the port of Kompong Som toshipping. But Hanoi would probably hesitate to make great use of tho port In the short run; it would almost certainly want to wait to see Ikiw the US and South Vietnam reacted to Cambodia's collapse, and it would not want or need to reveal its strategic plans by pouring supplies tlrrough Kompong Som.

n the limit term, the major importommunist victory in Cambodia on Hanoi's intentions In South Vietnam would be more psychological than military. Hanoi might hope that the fall of Cambodia would so unnerve the South Vietnamese that tl* stage would be set fc* major actions in South Vietnam.

In this effort, the CVN has significantly improved its military ami political position.

Thus, even though there are occasional grumblings within the mili-tary hierarchy over Thieu's political actions, there is no iigurc in the military who appears capable of seriously challenging him. There is little prospect of this situation changing SO long as Thieu maintains the imageirm and effective auticomiminist leader who commands continuing US support, although ambitious men remain in the wings.

The government structure is becoming increasingly centralized and personalized, with loyalty torime prerequisite for any significant government assignment.

Altlmugh the GVN will have little trouble in coping with overt communistaction, dealing with the communists' covert activities will be difficult. This task falls largely to the CVXs kieal paramilitary and police forces, whose effectiveness varies widely from place to place. Police elfcctive-ness is generally good in the larger urban areas, but falls off rapidly the further one goes into tlie countryside.

Increased foreign und doinc&tic investment couldthe situation, but, for lhe short run. it is limited because of the uncertainties of the GVN's long-term viability. Ihe basicol inflation ami stagnation defy quick solutions and could come to have adverse political ramifications. But for the short run. as long as US economic assistance is available, such problems are not likely lo reach critical dimensions.

A more problem, however, and one which could lead to some popular resentment against tlie government, is the availability of rice. Tho fighling in the Delta last spring conlrihuteclhortfall in rice production in South Vietnam. Ihis, coupled with difficulties in obtaining immediate rice imports becauseorld shortage, raises the spectreerious rice shortage in the late fall.ikely toemporaryhowever, since additional quantities of American rice should arrive in South Vietnam by late December.

The communists are actively seeking to exploit tho GVN's economic difficulties, while trying to reduce the economic burden on the North. Apart from enforced taxation, thehave alwayshadow supply system in South Vietnam, buyingfuel, and pharmaceuticals on tbe local economy.

On balance, however, it is highly unlikely over the short term that the communists will make significant gains in exploiting or even seriously aggravating Saigon's economic problems. Moreover, the severely restricted economic situation in PRC areas will reinforce theneed for continued taxation andpurchases in the CVN areas.

Con RVNAF AW Ihc Challenge?

The South Vietnamese have Urge and well-CO,nipped armed forces. Tlicir combat effectiveness is undercut, however, by logistic and maintenance deficiencies and shortfalls in training, command and control, andof units. Corruption and desertion in the armed forces continue to he problems. In addition, the ground forces, including mobile reserves, are fully deployed.

On the other hand, RVNAF hassignificantly in recent years, especially since the start of2 campaign, as Thieu has cashiered many inept officers.

Moreover, with the withdrawal of US air assets, the GVN's firepower advantage in many parts of the country is less impressive. The amount of CVN artillery tubes currently exceeds that of the communists, but the North Vietnamese liave demonstrated greater proficiency in the use of such firepower. The communist tank

Massive air support and exclusiveof the sky have born crucial factors in AKVN's defensive und offensive capabilities. Most of this support was American; thequestion now is whether the GVN ground forces could manage without it. The South Vietnamese Air Force cannot begin to provide the abundance of air support that ground commanders were accustomed to prior to the cease-fire. Even so. VNAF ground support capabilities have improved considerably and should help to counterbalance communistin most of the country.

In northernowever, where RVNAF is clearly most vulnerable, VNAF air operations would be severely hampered by the heavy concentration of NVA AAA/SAM forces. In addition, the North Vietnamese areosition to mount air operations ol their own inn the event of an all-outoffensive, we believe that they would do so. Tbe effectiveness of North Vietnamese close air support, however, would be curtailed by Inexperience in ground support operations and the paucity of ground radar controlIn terms of air defense.

A, The GVN

Prospects for the CVN over the next nine mouths arcOn the one hand. Thieu's political position will probably grow stronger, and the communists are unlikely to make significant political gains. On the other hand, by next summer, the GVN may no longerilitary edge over theif Hanoi continues its current level of buildup in thewe believe it will do.

The GVN. facedituation where its real options are limited, will basically de-vole its efforts to strengthening the country's infrastructure, maintaining and building up its military defenses, and attempting to counter Hanoi's thrusts. Continued US military and economic support will be crucial to the GVN's performance and prospects during this period.

Tbe GVN will push with equal force to forestall the resurgence of the communist infrastructure, but will be facedilemma. Aggressive localchiefs can often interrupt communist efforts to build bridges to the local population, bul government harassment often prompts communist retaliation. The ensuing rash of terrorism and military activity upsels the local population, whose lives and livelihoods are threatened by the lack of security.esult, the local chief often loses his popularand Is hard pressed to prove that he indeed has "pacified'" his territory. Caught in this situation, tlie local officials frequently find it preferable to seek the apparent quiet provided hy accommodation.

Militarily, RVNAF can be expected to continue its operations against communist positions. especially against enclaves notto the western corridor, and against NVA efforts to move into new areas.

It is unlikely, however, that the CVN would undertake such an action prior to consulting its American ally.

B. The Communists

n assessing Hanoi's military Intentions, we are hobbledack of firm intelligence. In fact, the communists have probably not yet

It is clear,that Hanoi is acting to preserve an option to resume major military action in Southat someThe chances fur theaspects of the Paris agreements being realized an? negligible; nor can Hanoi have much hope of achieving the GVN's collapseombination of political andwartare backed up by only moderate military pressure.

The question, however, is when?

The forward positioning of communist forces and supplies and the improved road .system give Hanoi the capability to kickajor military campaign with littlepreparation. As Hanoi continues to augment its forces in South Vietnam during the coming dry season, the military balance may tilt to the communists' advantage unless there is countervailing US support for the GVN.hift in the military balance could encourage Hanoi to launch majoraction.

Recent Indications that the beginning of the new dry season will bring additional movements of men and equipment to the South further strengthen Ibe case that Hanoi may be preparingaior offensive during this dry season.

With sufficient stocks of equipment and munitions in the South to engage in heavy combat for the duration of an entire dryit is unlikely that pressure from Moscow Or Peking willecisive factor inthe North Vietnamese Irom starting un offensive.omplete cutoff of Soviet and Chinese exports to North Vietnam would affect Hanoi's domestic economy long before it affected the war in the South, and it is highly unlikely tliat Moscow or Peking would taketep.

Further, Hanoi may well now regard the risk of the reinvolvement of US combat forces (air as well as ground) as fairly small. North Vietnam's view of the risk probably would not restrain its leaders fromajor offensive if they felt Other factors were favorable. Throughout the coming months, Hanoi will be constantlyits views on this matter. Political trends in the US that seemed to further restrict or to liberalize; tbe President's power to react, would of course affect Hanoi's assessment of the risks.

inally, the North Vietnamesemay see its chances ofajor military victory as being greater in the springhan later. There is an appreciable volume of evidence that the communistsbelieve they are doing badly in the political struggle in South Vietnam, and that in this struggle time is on the side of the GVN, not the communists. If this is the case, ihere are almost certainly elements within the Hanoi leadership which favor aof military notion stumer rather than later. North Vietnam's leaders might alsothat US domestic problems are likely to bethe restraints on theactions morethe next six to nine months than would be theear or two later. Moreover, if the Soviet Union and China are reducing arms aid to Hanoi, the North Vietnamese might consider that they would be at their maximum strength for an offensive during the coining dry season.

The arguments uhieh persuatte other analysts that the North Vietnamese Will delay an offenthv Ixyond the current dry season are an follows:

n contemplating prolonged heavy corn-kit. Hanoi would also want to be assured of enough continued material support from Moscow and Peking to cover losses. Such assurances are unlikely over the short term. Despite the heavy stockpiles in or adjacent to South Vietnam, it would be exceedingly dangerous for Hanoi loo-it-alone strategy.

he situation in Soulh Vietnam will alsoompelling factor in Hanoi's policy choice. Although the communists have made signifieiiut strides in building up their military forces.

Hanoi will also continue toajor effort to rebuild Uie communistinfrastructure, immediately in contested rural areas and ntore gradually in towns and cities; however, we anticipate only limited

success in ihis effort. The commiitiists will, moreover, attempt to entice the population to move to PRC areas, and governmentwill be approached to arrange local ad hoc trade agreements and "peacet the same time, the communists will continue trying to infiltrate the government's ranks for intelligence and subversive purposes. Some increase in terrorist and guerrilla activity is likely as the communists try to break down CVN control at the grass roots and enforce popular tolerance of their own presence.

v. over the longer term

GO. The foregoing summary of prospects over the short term reflects the impossibility of offering confident judgments on the timing and shape of future communist militaryNorth Vietnam'sover the shortbe influenced by itsof shifts in the relative balance of power, military or political, in Vietnam or in the positions of ils own allies or the US. If Hanoi does notajor offensive during the upcoming dry season, the question remains whether the communists are likely to opteturn to major hostilities ot some point relatively soon thereafter.

lie strength of the Americanto South Vietnam will continue toital factor for the CVN's survival. Not only will it influence Hanoi's policy decisions, but it will alsoritical political andfactor in maintaining GVN confidence. Continued US military aid will be essential,tltough tlie amounts allowed by the Paris agreement are not likely to offset the expansion of NVA strength in the South. Further large-scale US economic aid will also be required if the GVN is tohance to solve its economic problems. Other sources of external financing, such as offshore oil and foreign investment, offer good potential but will require several years to make adent In South Vietnam's foreign aid requirements.

Apart from US support to Souththe overall American military posture in the Far East will also Ih' carefully noted byajor US disengagenvent from the area,ulling apart of tlie American alliance withthe site of American reserve forces potentially available tobe demoralizing toand would encourage Hanoi (and pussihly its allies) lo fed that the risk of confrontation with tbe US was negligible. Even in theof such signals, however, it cannot be assumed what conclusions Hanoi would draw concerning US intentions. Hi record forthe depth .tml duration of the US commitment to the CVN is well established.

At the same time, the willingness or reluctance of Peking and Moscow toanother major military effort to topple the GVN will condition North Vietnam's strategy. At some point, the North Vietnamese are likely to press China and the USSR for substantially increased military aid. This will force these countries to weigh the impact of responding on tlielr relationship with the US and with each other. Great power detente has contributedampening of tbeconflict; ft hu also served to undercut the North Vietnamese ability to play tlieir alhes off against each otlser. There are no indications now that these conditions will not continue for some time.

ut there are conceivable developments that might make the Chinese or the Soviets (or both) more receptive to Hanoi's unpor-tunings. For example, if the Chinese andcame to lx-llcvo that Washington was no longer so devoted to the GVN's survival as to risk progress in furthering detente, Hanoi's allies might think it safe to provide

Nunc of these possibilities appears likely,. they occur, they would isolate the American commitment to Saigon as the major external restraining force on Hanoi

n weighing its longer-term strategy, Hanoi will also be sensitive to political and military trends in Southteady consolidation of power by Thieu. with little obvious deterioration of RVNAF capabilities,ailure of the communists infrastructure to make inroads of any significance into the GVN's control of the population wouldHanoi's determination to reunify

In Sum. The key factor shaping Hanoi's policies will remain its iwrccption of the likely US response, the availability of externalthe pressure imposed by Moscow and Peking, and military and political trends in Soulh Vietnam. Over the longer run,Hanoi may place greater weight on the trends Jl observes In lhe Smith than on the external restraints imposed by Moscow.anel Washington.

In any event. Hanoi's actions arc clearly designed to insure that it can again resort to major military action to gain its objectives if other means fail.ajor communistoffensive does not occur in the upcoming dry season, we believe that tbe odds favoring such iin -iction will increase significantly asry season approaches.
