The Soviet Union’s ambassador to the United Nations, who had been boycotting proceedings since January over Taiwan, was expected to return to the Security Council and vote against the resolution, but Stalin told him to stay away. Two days later tacit agreement was received from the Soviet Union that American intervention would not lead to an escalation. Stalin did nothing to prevent Western involvement in the conflict. He alone knew that Mao had made a commitment to sending troops to Korea. Perhaps he hoped that China would destroy large numbers of Americans in the conflict.
