I think it was Kosegin.
Nikita Khrushchev is the Soviet general secretary who denounced Stalin's policies in a famous speech in 1956 and supported the development of a robust space program, which eventually led to the launch of Sputnik in 1957.

---- Leonoid Brezhnev was the new leader of the Communist Party in the Soviet Union. (1964) He replaced Nikita Khrushchev. As the new leader, he replaced many of Khrushchev's policies to expand the freedoms of the ordinary Soviet citizen and to allow critcism of the Soviet system. He died in 1982.
The General Secretary/Premier Nikita Khrushchev removed nuclear missiles from Cuba after a very tense nuclear drawdown in the U.S.
General Secretary of the Communist Party of the Soviet Union was created in 1917.
Nikita Khrushchev became the General Secretary of the Communist Party of the Soviet Union after Stalin died. The General Secretary's position was the real seat of power in the Soviet Union at the time. In that sense only can it be logically said that Khrushchev "lead communism" after Stalin died. It would be incorrect to say that he "lead communism," because "communism" existed in several other countries and neither Stalin nor Khrushchev lead those countries. One could say that Nikita Khrushchev lead communism in the Soviet Union in particular, but not that he lead communism in general.
Nikita Khrushchev was General Secretary of the Communist Party of the Soviet Union until they forced him into retirement. Contrary to what Fox News may claim, he was never an American politician.
Stalin was the General-Secretary of the Communist Party in the USSR (the Soviet Union).
Khrushchev inched toward more peaceful relations with the democratic west.
Khrushchev is the one who declared that communism for the Soviet Union would improve his nation's standard of living. He did this while calling for the peaceful co-existence of the western powers.
