I don't think you could call Khrushchev and Castro friends. More like allies with a common enemy. Khrushchev would have been the superior of the two as the leader of the Soviet Union and I think he would have looked upon Castro as a leader of a Soviet satellite nation. Castro hadn't been the leader of Cuba for very long when he forged his alliance with Khrushchev. Having Khrushchev as an ally would have given him some much needed power on the world stage and protected his position in Cuba. For Khrushchev 's part Cuba gave him a foothold off the coast of the United States which he would have considered valuable for the Soviet purposes.

Nikita Khrushchev
The result of the rise to power of Nikita Khrushchev was he became the leader of the Communist Party in the Soviet Union. Nikita Khrushchev was leader of the Soviet Union in the early to mid-1960s.
Joseph Stalin
Nikita Khrushchev became head of government after Malenkov. Khrushchev already was head of the Communist Party, but consolidated his power by taking titular head of the Soviet Government as well.
Nikita Khrushchev Immediately after Stalin's death, Georgy Malenkov became the Premier of the Soviet Union while Nikita Khrushchev became First Secretary of the Communist Party. Both were in a position to wield authority, so the two ruled together in an uneasy alliance.

Nikita Kruschev. He became Secretary of the Communist Party in 1956, and later went on to serve as the Prime Minister of the Soviet Union until he left office in 1964. It was his idea to place missles in Cuba capable of reaching almost any point in the United States.
If I understand the (mistyped) question correctly, the answer is Joseph Stalin.
Nikita Khrushchev was Premier of the USSR from 1958 to 1964, but he was the First Secretary of the Communist Party (i.e. the most important person) from 1953 to 1964.
After Joseph Stalins death Nikita Khrushchev took over. http://en.wikipedia.org/wiki/Nikita_Khrushchev
At first, after Stalin died Georgi Malenkov became Prime Minister of the USSR and Nikita Khrushchev became General Secretary of the Communist Party. In the USSR, the real power was in the Communist Party, so Khrushchev was able to force Malenkov out, take over both positions and become the sole leader.
He was First Secretary of Communist Party from 1953-64. He became Premier(Chairman of the Council of Ministers) from 1958. In 1964, he was removed probably because of the Soviet-Chinese conflict.
