In the midst of the conflict in Vietnam, Nikita Khrushchev is as both premier of the Soviet Union and chief of the Communist Party after 10 years in power. He left office the next day, October 15, 1964. He was succeeded as head of the Communist Party by his former protégé Leonid Brezhnev, who would eventually become the chief of state as well.
The new Soviet leadership increased military aid to the North Vietnamese without trying to persuade them to attempt a negotiated end to hostilities. With this support and no external pressure to negotiate, the North Vietnamese leadership was free to carry on the war as they saw fit.
