In late 1952 Eisenhower went to Korea and discovered a military and political stalemate. Once in office, when the Chinese began a buildup in the Kaesong sanctuary, he threatened to use nuclear force if an armistice was not concluded. His earlier military reputation in Europe was effective with the Chinese. The National Security Council, the Joint Chiefs of Staff, and the Strategic Air Command (SAC) devised detailed plans for nuclear war against China. With the death of Stalin in early March 1953, Russian support for a Chinese hard-line weakened and China decided to compromise on the prisoner issue.
What event led to decreased Russian support for China?
death of Stalin
