Answer
It is true that Suslov was the second-in-command during Brezhnev's era. Suslov was a Soviet Communist Party leader and a member of the Politburo from 1952 until his death in 1982. He was considered to be the second-most powerful man in the Soviet Union after Brezhnev. Suslov was a conservative and a hard-liner who opposed reform and opposed détente with the West.
