Moscow was, on the other hand, more than happy to have the United States involved in such a difficulty. At some quite early point in 1985 — just when is not quite clear — a Soviet emissary went to North Korea to press the leadership there to be ready to take, at the least, some military action against the South, at best to launch a full-scale war at the right moment. The idea was an ingenious one. It would draw US forces to Korea, men who might otherwise go to the Gulf or Europe. The US Navy would have to get their equipment there, which would hamper its operations in the Indian Ocean. A large number of US aircraft would be tied down in Korea and Japan. As a bonus it would present China with a dilemma: should it give help to North Korea, a communist state and an old ally, but at the cost of opposing the United States and thus indirectly aiding the Soviet Union; or refuse help, in which case North Korea would become a Soviet client? Japan, too, would have to decide whether to allow the United States unfettered use of bases in Japan. If it did and China helped North Korea, that would set Japan and China at odds with each other, which would be good for the Soviet Union. If Japan refused to allow use of the bases this would cripple US support of South Korea and split the United States and Japan. All in all, the Soviet Union had much to gain if trouble could be started in the Korean peninsula.
Peking, however, had highly-placed friends in Pyongyang, where reasons of ideology and personal ambition promoted factions that gave their support, open or hidden, either to the Soviet Union or China and not always consistently at that. The Chinese leaders got wind of the initiative and had no intention of allowing events to develop as Moscow planned. A very senior member of the Politburo and, just as important, the Deputy Chairman (a general) of the Chinese Communist Party (CCP) Central Committee's Military Affairs Committee (the supreme military command) went with him. Quietly but very firmly the North Koreans were told that if they started a war at this particular juncture there would be no Chinese 'volunteers' this time; they would be on their own.[25] Both knew there would be no Soviet assistance beyond a few weapons; Soviet troops would be too busy looking after their own security on the Chinese border and elsewhere.
This blunt warning, impressed not only on the politicians in Pyongyang but also on the North Korean generals, many of them known personally to the Chinese general from the Military Affairs Committee through their service together in the Korean War of 1950-3, seems to have gone home. At all events, North Korea did very little when the time came, mounting just a few minor raids. The North was clearly not going to risk the enmity of a growing China, just as China was not going to risk having Pyongyang fall into unfriendly hands; North Korean territory was too close to Manchuria for that. Perhaps also the North thought the time was not appropriate anyway; after all, the emissaries had been careful during the talks not to rule out action later on, when circumstances might be more suitable. Better wait and see how the Soviets got on first.
The raids, principally with light naval units, did cause the Americans and the Japanese some alarm since it was not quite clear at the time whether they presaged something bigger. The South Koreans, of course, mobilized completely and appealed to Washington, describing the threat in their usual rather dramatic terms. Washington was not so sure about things, but did send two fighter squadrons, to comfort Tokyo. Preparations were made to move some ground forces to the peninsula but the Soviet Union collapsed before they arrived and the men were in the event sent instead to Vladivostok to supervise the surrender of some of the Soviet forces in the Far East.
Just as the Soviet Union wanted to avoid full-scale war in Asia, so did the United States; they both had their hands full elsewhere. China did not want it either, and was not ready for it unless the Soviet Union emerged from the war very much weaker, in which case China might well be tempted into taking advantage, in the Marxist jargon, of the new correlation of forces. Japan did not want war at all, despite its new foreign policy direction. To its relief it saw the danger approach and then happily recede, though it’s new strength left it able to throw useful weight into the Western side of the scale had it been needed. Japan also took the opportunity later of profiting from the Soviet fall.
