I also doubted that the Chinese could succeed, and I advised them to come to a temporary agreement with Chiang Kai-shek. Officially they agreed with us, but in practice they continued mobilising the Chinese people. And then they openly put forward the question: ‘Shall we go on with our fight? We have the support of our people.’ We said: ‘Fine, what do you need?’ It turned out that the conditions there were very favourable. The Chinese proved to be right, and we were wrong.
Stalin was performing the role of a leader who recognises his own fallibility in order to get his way on the Balkans. But a bullying style came more naturally to him. The People’s Republic of China, with its military and economic potential, could become a handful inside the world communist movement and Mao Tse-tung could become his nightmare. So for once he was probably blurting out what he really thought.
Belatedly he saw the need to deal more tactfully with Mao. Kim Il-Sung had made his final plea at a moment when Stalin was most amenable to having his mind changed; and anyway Stalin could not be certain that the Chinese would not support Kim Il-Sung even regardless of the USSR’s consent. Stalin did not disclose his calculations. Molotov was by then in semi-official disgrace and was no longer privy to his thoughts, and everyone in the Ministry of External Affairs simply followed Stalin’s orders.
Thus it came about in their meetings in Moscow in April and May 1950 that Stalin sanctioned Kim Il-Sung’s request to support the Korean communist resumption of war. Both Stalin and Mao had allowed themselves to be persuaded that the military campaign would be short and successful.6
Soviet arms, munitions and other equipment were carried by the Trans-Siberian Railway to Korea. Kim Il-Sung began his offensive on 25 June. Superior in every sector of military resources, the Korean communist forces swept south and captured Seoul three days later. It looked as if the basic premise of Stalin’s discussion with Kim Il-Sung was about to be realised as a rapid victory was achieved before the rest of the world could blink. But the two communist interlocutors had made a profound miscalculation. Truman was shocked but not deterred. Instead he ordered his diplomats to go before the United Nations Organisation Security Council and secure a vote in favour of armed intervention to prevent the overrunning of South Korea. This task was facilitated by a previous blunder by Stalin who, objecting to the continued recognition of Chiang Kai-shek’s regime in Taiwan as the legitimate Chinese government and its right to occupy China’s seat in the Security Council, had been boycotting the body. In the absence of a Soviet veto, the Security Council approved the American proposal. Stalin repudiated the advice of his Ministry of External Affairs to drop the boycott so as to prevent the Americans and their allies from landing with the legitimacy conferred by the sanction of the United Nations.7This was hamfistedness on a scale he had not shown since 1941. The United Nations forces, primarily American, were led by General Douglas MacArthur. Their rapid deployment was made possible by the American occupation of nearby Japan, and by the end of September they had already halted the communist advance and retaken Seoul. Next month they had crossed the 38th Parallel into north Korea. Kim Il-Sung was desperate; he had no alternative but to turn to Stalin for direct military assistance even though he knew the likely response. Mao Tse-tung was less reluctant since he assumed that war between the USA and the People’s Republic of China was just a matter of time. The Chinese resolved upon aid for the Korean communists before consulting Stalin. But Mao still expected the Kremlin to send weapons for the use of the twelve divisions about to be dispatched by China.8
The news of MacArthur’s success came through to Moscow; it was relayed to Stalin beside the Black Sea. His was a curiously semi-detached oversight over Soviet security interests notwithstanding his ability to stay in touch by phone and telegrams. When he was down in the south he held none of the frantic face-to-face discussions with political and military leaders such as had been his wont in the Second World War. Suddenly the crisis on the Korean peninsula deepened, and Stalin had to take a strategic decision. Kim Il-Sung demanded urgent additional assistance, pointing out that without help the communists would soon lose the entire war.
