The unprovoked attack on the Republic of Korea by the armed forces of the Soviet- controlled North Korean government opened a new phase in the power conflict between the USSR and the non-Soviet world. For the first time since the end of World War II, the USSR deliberately attempted to expand the Soviet- Communist area of control through direct ac- tion against a non-Soviet state by the organ- ized military forces of a puppet state. Apart from the immediate strategic advantages of Communist control of all Korea, the primary aim of the USSR in instigating the attack probably was to discredit the US policy of gen- eral containment of Soviet-Communism. US intervention, endorsed by nearly all of the non-Soviet members of the UN (including India), marked a line beyond which Soviet- sponsored aggression could not go without be- ing challenged. A failure to draw this line would have seriously discredited the whole US policy of containment, gravely handicapping US efforts to maintain alliances and build po- litical influence with the Western European powers and with other nations closely aligned with the US. The Korean incident as a whole, particularly the virtual collapse of resistance by the Republic of Korea and the interposition of US forces in the path of the attack, raises several problems of the gravest importance to US security. Outstanding among them is the possibility, that reverses in the fighting in Ko- rea may quickly counter the favorable initial psychological effects of intervention and bring about a drop in the morale of the Western world. 2. Whatever turn events take in Korea, the USSR has the capability of creating a series of incidents roughly comparable to the Korean episode, each one threatening either to bank- rupt the US policy of containing Soviet-Com- munist expansion or to disperse and overstrain US military forces in readiness. Soviet leaders might estimate that the USSR was warranted in running the risk of global war inherent in the repetition of the Korean pattern elsewhere, reasoning either: (a) that the US would abandon or drastically reduce its commitments, particularly in Asia, before it would challenge the USSR directly; or (b) that the outbreak of global war in which the US took primary responsibility for enlarging the area of conflict would leave the non-Soviet world critically divided and weak. The Far East (Taiwan, Indochina, Burma) and, the Balkans are the border areas where signs of impending military action are mounting. 3. While the early reaction of Western Eu- rope was to give enthusiastic approval to the US intervention in Korea, the Western Euro- pean nations are unlikely to take resolute and coordinated action to meet the challenge im- plicit in the "limited war" phase of world power conflict unless US military power can be mobilized and deployed in strength that is plainly sufficient to constitute at least a sub- stantial deterrent to further Soviet or Soviet- sponsored military aggression.

Limited War in Korea. The unprovoked attack on the Republic of Korea by the armed forces of the Soviet-con- trolled North Korean government opened a new phase in the power conflict between the USSR and the non-Soviet world. For the first time since the end of World War II, the USSR deliberately attempted to expand the Soviet- Communist area of control through direct ac- tion against a non-Soviet state by the organ- ized military forces of a puppet state. Al- though the USSR may claim that the conflict in Korea was a civil war, it cannot disguise either the fact that North Korea is a Soviet puppet or the fact that the attack was launched against a state whose sovereignty had been recognized by the UN. In Eastern Europe the postwar techniques of Communist expansion have not gone beyond propaganda, sabotage, subversion, in- ternal coups, and guerrilla warfare cam- paigns-supported by Soviet diplomacy and the threat of Soviet military force. Even in Greece, Iran, China, and Indochina, Commu- nist activities have remained within the limits of insurrectionary fighting in a "revolution- ary" situation within a single state. a. The Attack. The North Korean venture, involving an ad- ditional step toward open Soviet aggression, amounts to a laboratory test of the advantages the USSR might gain by fighting a war of lim- ited objectives and limited liabilities through the medium of puppet troops. Soviet objec- tives were limited in the sense that the North Korean forces proposed merely to bring about the "unification" of Korea within its tradi- tional national boundaries rather than to pro- voke a global war involving the US. Soviet liabilities were limited because the USSR avoided becoming openly and unequivocally associated with the attack despite the fact that the North Korean forces were Soviet-ad- vised, Soviet-equipped, Soviet-trained, and Soviet-supplied. In planning the Korean invasion the USSR probably did not expect the US to intervene with its own military forces. In the absence of US intervention, Soviet leaders could antici- pate a quick Communist victory that would present the US and the UN with an accom- plished fact, undermine the confidence of non- Communist states in the practical value of US moral commitments, and give political and military momentum to the further expansion of Soviet-Communist influence in the Far East. Apart from the immediate strategic ad- vantages of Communist control of all Korea, the primary aim of the USSR in instigating the attack probably was to discredit the US policy of general containment of Soviet-Com- munism. b. US-UN Reaction. Whatever the original intent of the move in Korea, the prompt US commitment of its own military forces in a "police action" on behalf of the UN automatically converted the Korean incident into a critical issue. The US inter- vention, endorsed by nearly all of the non- Soviet members of the UN (including India), marked a line beyond which Soviet-sponsored aggression could not go without being chal- lenged. A failure to draw this line would have seriously discredited the whole US policy of containment, gravely handicapping US efforts to maintain alliances and build political influ- ence with the Western European powers and with other nations closely aligned with the US. The immediate psychological reaction of the Western world to US-UN intervention in Korea was almost uniformly favorable, and the mo- rale of nations committed to the containment .Of of Soviet-Communist expansion received a lift. Nevertheless, the Korean in- cident as a whole, particularly the virtual col- SECRET 2 Approved For Release 2003/06/20 : CIA-RDP86B00269R000300040004-0 Approved For Release 2003/06/2(b:fly~RV1~86B00269R000300040004-0 lapse of resistance by the Republic of Korea and the interposition of US forces in the path of the attack raises several problems of the gravest importance to US security. Outstand- ing among them is the possibility that US re- verses in the fighting in Korea may quickly counter the initial psychological effects of in- tervention and bring about a drop in the morale of the Western world. c. Effects of a Prolonged Battle in South Korea. The efficient military performance of the in- vading forces in the first three weeks of battle indicates that there is little probability that the North Koreans can be quickly driven back to the 38th parallel. The USSR can supply material aid in sufficient quantities to pro- long the fighting and deeply involve the US in Korean military operations. Chinese Com- munist troops can be brought into action covertly and, if necessary, openly. The USSR might consider that the risk of provoking a global war was not substantial so long as no Soviet forces were openly committed. A prolonged battle in South Korea, which now seems probable, would seriously damage US prestige. The Western European allies and other nations aligned with the US would steadily lose confidence in the military value of US commitments to assist them against armed aggression and would be increasingly reluc tant to take energetic measures in support of the North Atlantic Treaty Organization (NATO) and the Mutual Defense Assistance Program (MDAP). While some credit might redound to the US for initially honoring its commitments, more anxiety will arise about US ability to counter threats of Soviet aggres- sion than about US intentions to do so. A major commitment of US forces and equip- ment in Korea would seriously limit US capa- bilities for taking military action elsewhere, and Western European nations in particular would feel dangerously exposed. While the US would encounter all of these disadvantages from a local but prolonged war in Korea and the USSR would reap corresponding advan- tages, the USSR could also register propa- ganda gains in non-Soviet countries. where "peace" propaganda has a strong appeal by emphasizing Soviet non-interference (in the technical legal sense) and portraying the US action as an imperialistic Western aggression against an Asiatic people. d. Effects of a Military Reverse. for US Forces in South Korea. The immediate consequence of a failure of US forces to hold South Korea, a possibility that cannot be ruled out, would be a damaging blow to US prestige. The US would then vir- tually be forced to try to regain as much of its lost military reputation as possible by com- mitting substantial US military resources in a difficult and costly invasion of an area that is not in itself of primary strategic importance to the US. Whatever the US did to redeem its military reverse, US foreign policy and espe- cially US military capabilities would be seri- ously discredited. A voluntary withdrawal of US forces to avoid the military risk of being driven off the Korean peninsula would not reduce and prob- ably would increase the damage to US strate- gic interests all over the world. Voluntary withdrawal not only would show US moral commitments to be unreliable when put to a severe test, but in addition would leave grounds for considerable doubt as to the abil- ity of the US to back up any of its commit- ments with adequate military force. Besides shaking the confidence of the Western Euro- pean allies and other nations on whose strength and cooperation the policy of con- tainment depends, withdrawal from Korea would damage US standing in UN affairs and would undermine the effectiveness of the UN as a device for mobilizing Western resistance to Soviet-Communist aggression. Pro-US governments, particularly in areas where the USSR could initiate limited military aggres- sions without openly using Soviet forces, would suffer serious losses of prestige. In some cases (for example, Indochina or Iran) these governments might lose control of the country altogether or feel compelled to seek an accommodation with the USSR. The total effect of voluntary withdrawal on world-wide US security interests would be a reverse prob- ably more calamitous than the effect of a US failure to hold Korea.

Whatever turn events take in Korea, the USSR has the capability of creating a series of incidents roughly comparable to the Korean episode, each one threatening either to bank- rupt the US policy of containing Soviet-Com- munist expansion or to disperse and overstrain US military forces in readiness. Without di- rectly and openly involving Soviet military forces, the USSR could engineer the outbreak or (where guerrilla fighting is already going on) the rapid intensification of local wars in Taiwan, Indochina, Burma, and the Balkans. The effects of incidents in these areas could be aggravated by renewed pressure in other places bordering the Soviet sphere. In Iran in particular the pro-Soviet Tudeh Party and other subversive elements either within the country or in adjacent Soviet territory are ca- pable of creating disorders which the USSR might use as a pretext for invoking the 1921 Irano-Soviet Treaty and "restoring order" in Iran with Soviet troops. The use of puppet forces (or Soviet forces in the special circumstances in Iran) would involve some risk of global war. The USSR probably will not deliberately initiate global war at this time in view of : (a) the general superiority of the US in total economic and military power potential; and (b) doubts about whether the newly developed Soviet ca- pability for atomic attack is as yet capable of neutralizing US atomic retaliation and pre- venting the US from mobilizing its economic and military power. Nevertheless, Soviet leaders might estimate that the USSR was warranted in running the risk of global war inherent in the repetition of the Korean pattern elsewhere, reasoning either: (a) that the US would abandon or drastically reduce its commitments, particu- larly in Asia, before it would challenge the USSR directly; or (b) that the outbreak of global war in which the US took primary re- sponsibility for enlarging the area of conflict would leave the non-Soviet world critically di- vided and weak. Whatever Soviet intentions may be, signs of impending military or quasi-military action on a large scale are mounting in nearly all the border areas. These signs may be part of the war of nerves or a concerted deception plan designed to prevent US concentration of effort on the Korean operation. Some of them may be feints to draw attention away from new moves in just one of the trouble spots. It is conceivable, however, that the USSR plans aggressive action of some kind at all these points within the next year or two. In any case the pressure continues to be heavy, and possibility of early initiation of new Ko- rean-style incidents by non-Soviet Communist troops cannot be excluded. a. The Far East. It is not yet clear whether the USSR will force the Chinese Communists to give open military support to the Korean operations or to start a new operation elsewhere in the area. The Peiping regime is unlikely to commit mili- tary forces to operations outside China on its own initiative, but almost certainly would comply with a Soviet request for military ac- tion. Chinese Communist troop strength and dispositions would permit intervention in Korea and military action in a number of other places as well with little or no warning. Forces in considerable numbers apparently are being staged on the mainland opposite Taiwan, and possibly opposite Hong Kong. Although no significant changes have oc- curred in the strength of troops stationed along the Southeast Asian frontiers, these forces are capable of crossing into Indochina if necessary to strengthen Ho Chi Minh's fight- ing forces or into Burma, where the presence of a few fugitive Chinese Nationalist troop units would give a show of legality to a mili- tary incursion. b. The Balkans. There have been a number of indications of an acceleration of Soviet and Satellite troop movements in the Balkan area. Soviet mili- tary equipment and supplies have been flow- ing into the Balkans for several months in quantities that appear to be in excess of the needs of Soviet forces available there. The number of Soviet troops in the Balkans has not changed significantly in the past six months, but the efficiency of Balkan puppet forces has probably been increasing as a result of a tightening of Soviet control and the acqui- sition of Soviet materiel. SECRET Approved For Release 2003/06/20 : CIA-RDP86B00269R000300040004-0 Approved For Release 2003/06/28 L.C F 86B00269R000300040004-0 While it is still probable that Soviet-Satellite troops in the Balkans are inadequate to mount a successful armed offensive against Yugo- slavia, it would be possible for puppet troops with covert Soviet support at least to start a local war on a considerable scale by moving across the borders of Yugoslavia, Greece, or Turkey. Soviet propaganda is emphasizing the imminence of hostilities in this area (through Greek and Yugoslav "aggression" of course). The initiation of any kind of armed aggression in this area by Soviet puppet troops would present the basic issues of the Korean incident all over again, forcing the US either to abandon some of its commitments or to dis- perse its military strength. 3. Western Europe. While the early reaction of Western Europe was to give enthusiastic approval to the US in- tervention in Korea, as time goes on sober sec- ond thoughts are bound to occur to the NATO nations. If the fighting in Korea is prolonged, as seems probable, or spreads to other border areas, Western Europeans are sure to fear that the US programs of military and financial as- sistance will be limited to present levels if not reduced because of the strains this peripheral fighting would put on US resources. On the other hand, fear of global war will be increas- ing, as will fear that the time may be short to prepare for defense against Soviet aggression in Europe. The Korean situation will bring sharply home to Western Europe the fact of its defenselessness against direct military ac- tion and may provide the US with an oppor- tunity to press for an increased defensive effort and more effective mutual aid and bal- ancing of forces. Resolute and coordinated action along these lines will be required if the Western European nations are to meet the critical issues that will confront them so long as Soviet-sponsored aggressions continue. The prospects of such action are not alto- gether reassuring in the light of the halting progress made to date in unifying Western European military and economic efforts. De- spite the strong resolutions adopted at the London conferences of May, the projected strengthening of NATO has hardly begun. The Schuman plan for integrating the Euro- pean coal and steel industries, one of the most promising economic integration schemes, is moving slowly. The French have proceeded vigorously to the heart of the economic unifi- cation problem by proposing to establish supra-national organizations and clearly rec- ognize supra-national authority. This radical departure from traditional political patterns alarmed the Benelux countries and caused them to retire for governmental consultations. Only the Germans, who have no sovereignty to lose at this point, and the Italians, whose industrial stake is comparatively slight, are inclined to accept the Schuman plan more or less as presented. The British, who are not negotiating but are being kept informed, con- tinue to make it plain that the UK would not participate in the plan the French have ad- vanced. The influence of France as a leader in Western Europe, which otherwise would grow as a result of the development of the Schuman plan, has remained uncertain be- cause of the protracted difficulties of forming a new French cabinet. The Western European nations may avoid giving way to apathy or despair and vigor- ously meet the challenge implicit in the "lim- ited war" phase of world power-conflict inau- gurated by the Korean incident. They are unlikely to do so, however, unless US military power can be mobilized and deployed in strength that is plainly sufficient to consti- tute at least a substantial deterrent to further Soviet or Soviet-sponsored military aggression.

The follow- ing is a digest made in April 1951 by the Office of National Estimates.7 Although an invasion of North Korea by UN forces could, if successful, bring several important advantages to the US, it appears at present that grave risks would be involved in such a course of action. (1) It is doubtful that US allies and other non-Soviet nations in the UN would support such a course of action. Asian nations, particularly India, would react unfavorably, and many Asians might be convinced that the US is, after all, an aggressive nation pursuing a policy of self-interest in Asia. (2) The invading forces might become involved in hostilities with the Chinese Com- munists. As it became apparent that the North Koreans were being defeated in South Korea, the Chinese might well take up defensive positions north of the 38th Parallel. The USSR might use Chinese Communist troops at any stage in the fighting, but their participation would be especially useful at the 38th Parallel where UN members could legally discontinue their support of the US policy. (3) Inasmuch as the USSR would regard the in- vasion of North Korea as a strategic threat to the security of the Soviet Far East, the invading forces might become involved, either directly or indirectly, in hostilities with Soviet forces, under conditions which would alienate most of Asia from the US UN cause in Korea. The conquest of North Korea would not provide assurance of peace throughout the country or of true unification.

Syngman Rhee and his regime are unpopular ai ong many -- if not a majority -- of non-Communist Koreans. To establish his government throughout all Korea would be difficult, if not impossible; even if this could be done, the regime would be so unstable as to require continuing US or UN military and economic support. If a UN trusteeship were established, it would be unstable. Korea once more would become the cat's-paw of international politics, and its ultimate status would be dependent upon the comparative strength and ambitions of the countries whose representatives supervised the trust administration. - 2 - Approved For Release 2003/06/20 : CIA-RDP86B00269R000300040004-0 Approved For Release 2003/06/20 CIA-RDP86B00269R000300040004-0 CI NTRAL INTELLIGENCE AGE cy IPi`I'ELLIGEIJCE IJE11.11 NO, 321 8 September 1-950 SUBJECT: Probability of Direct Chinese Communist Intervention in Korea RIOllLEM: To assess the probability of an open Co 1-.t ,ient of Chinese Communist armed forces in Korea, SCOPE: The corr:dtuent of both regular and local Chinese Corn- present.

Although there is no direct evidence to indicate whether or not the Chinese Communists will intervene in North Korea, it is evident that the Chinese Communists or the USSR must supply trained and equipped combat replacements if the North Korean invasion is to achieve complete control over South Korea before the end of the yearn Reports of an increasing Chinese Cormnunist build-up of military strength in LTanchuria, coupled with the known potential in that area, make it clear that intervention in Korea is well within immediate Chinese Communist capabilities. Ltoreover, recent Chinese Comm unist accusations regarding US "aggression" and "violation of the Manchurian border" may be stage-setting fcr an imminent overt move, This memorandum has not been coordinated with the intelligence organizations of the Depart-ients of State, Arrry, Navy, and the Air orco? The memorandum was prepared in accord with the request of the M rector of Intelligence, Headquarters? United States Air Force, 51 Approved For Release 2003/06/20 : CIA-RDP86B00269R000300040004-0 SECRET Approved For Release 2003/dVt~ '!'CIA-RDP86B00269R000300040004-0 In vievr of the momentous repercussions from such an overt action, however, it appears more probable that the Chinese Corunun.st participation in the Korean conflict will be more indirect., al- though significant, and will be limited to integrating into the North Korean forces "Manchurian volunteers," perhaps including air units as well as ground troops. 2. Present Status of North Korean Forces. The decision i nether or not to commit Chinese Communist forces will depend in part on the availability of Korean manpower, both in Manchuria and that part of Korea now in Communist hands. Current estimates by the Department of the 11rrrXr state that 40,000 trained Korean veterans who had served with the Chinese Con unists in the I?.anchurian campaigns of 1916 to 19W3 remain in Manchuria and there constitute a strategic North Korean reserve. It is noteworthy, however, that (1) since 1 itugust North Koreans have been using canbat replacements with as little as two week's training; and (2) the North Koreans would logically have committed all available organized Korean units soon after UPI forces had been comni Lted because at that time the impact of 40,000 trained troops probably would have been decisive. The foregoing considerations indicate either that any Korean reserve in 11anchuria was so dispersed that it did not constitute an effective reserve or that this reserve never in fact existed. Moreover, the possibility that Korean reserves in Manchuria have now been collected and reorganized and that some are now enroute to the combat area tends to be discounted by the fact that the time elapsed since 25 June should have permitted the organization and commitment of the majority of this reserve which would have been far superior in quality{ to those virtually untrained North Korean troops that have actually been utilized in the fighting. On balance, therefore, it appears highly probable that if a Com- munist victory in Korea is to be achieved by the end of the year the North Korean forces must now rely on either Soviet or Chinese Communist resources for decisive augmentation. 3. Chinese Communist C-abilities for Intervention. The Chinese Communists have approximately four million men under arms, including regulars, Military District troopsp and provincial forces. Following the fall of Manchuria there were approximately 565,000 IIlitaxy District troops in Manchuria (including 165,100 ex Nationalists), and possibly 100,000 to 125,000 of these 1) troops have now been integrated into the regular army and organized as combat forces. These units, as well as the remaining ID troops, probably are Soviet--equdpped. In addition,, reports during the past three months have indicated a considerable increase in regular troop strength in L nchn.nia., It is estimated that the major elements Approved For Release 2003i0WNT CIA-RDP86B00269R000300040004-0 Approved For Release 2003/0612MMA-RDP861300269R000300040004-0 of Lin Pine's 1._ `h Field Army -totalling perhaps 100?000 combat veterans----are now in :::anchuria and are probably located along or adjacent to the Korean bord r, in position for rapid commitment in Korea. Approximately 210,000 Communist regulars under I1ieh Jung-chent8 command are presently deployed in the Borth China area. Some of these troops have been reported enroute to Lia.nchuria. The Chinese Communists are believed to possess an air force totalling 200 to 250 operational ccxnbat aircraft, some units of which are reportedly deployed in Manchuria. 14, Indications of Chinese Communist Intention to Intervene. A. Pr22aaandlal.. Numerous Chinese Communist propaganda attacks on the US during recent weeks, charging the US with "intervention"s and s"aggression" in Taiwan, have been climaxed by two new protests to the UN claiming US air attacks in violation of the Manchuria-Korea, border. It is possible that these charges,, besides serving a use- ful propaganda function, may be aimed at providing an cause for Chinese Ca nist intervention in Korea. b. I111.itary Activity. Since the fall of Hainan in April 1950, reliable reports have indicated that elements of Lin Piao' a 4th Field Army noire being moved northward from the Canton areal 1.1ajor elements of the 4th Field Army are now believed to be either in or enroute to Manchuria. Other reports indicate that military construction is in progress near Antmung and along the Yalu :liver. Strengthening of Manchurian border defenses might either be a logical security development in view of the Korean conflict or a prelude to the offensive employment; of forces in the area, Reports of increased activity at Antung on the I.anchuria- Korea barer include the reported arrival of Chinese Communist aircraft. Antung has also been reported as the main base of the 1. Reports of preparation for this move were received as early as February 1950, well in advance of the assault on Hainan by LIN t s forces. Although these preparations may have been part of announced CCF plans for demobilization, it appears more likely that these elements were Korean troops of Lin Piao t s army being released to the North Korean Arras. 2, The three airfields in the Antung area could handle a total of 300 aircraft. 111M' Approved For Release 2003/06/20 : CIA-RDP86B00269R000300040004-0 Approved For Release 2003/06/20 : CIA-RDP86B00269R000300040004-0 =10 T North Korean Air Force, where that depleted force can seek refuge from UII air attacks. Numerous reports of recent North Korean activity, including revetment, construction at airfields south of the 38th Parallel have been received. These construction reports could indicate the imminent forward movement of air reinforcements for the North Koreans. Although some of this anticipated air sup- port might be provided by the as yet untested Chinese Cozmmini.st Air Force, there is no firm evidence to support such a contention. 5. Factors Ii?i.lifiating -aims- Chinese Communist Intervention. The conani.tment of Chinese Communist armed forces in Korea would clearly transform the Korean conflict from an ostensibly "internal" dispute to an international struggle. The decision to commit Chinese Communist troops to the Korean conflict would significantly affect the Soviet position in China as well as in Korea, and Soviet influence over both Peiping and Pyongrang might be jeopardized. Other factors which might tend to deter Chinese Communist interven- tion in the Korean war,, but which would be of minor consequence in so momentous a decision, are: (1) Chinese national and Wh itery pride might cause friction if Chinese troops were placed under Soviet or Korean command; and (2) Chinese Co unist intervention would probably eliminate all prospects for China's admission to the United Nations.
