"Kerry and his father’s foreign policy views were influenced by a faction of the State Department led by Dean Acheson"

Wasn't Dean Acheson Stalin's lawyer and the man most responsible for the diplomatic recognition of the USSR?

Not Stalin's lawyer, but close! I discussed his background a bit in Part 1. He was part of a pro-Soviet faction in the State Department in the early 1940s.
