Golitsyn's analysis was as little appreciated within CIA as it was in the outside world.
The John Birch Society took him seriously.
Angleton took Anatoliy Golitsyn seriously and wrecked the CIA for nearly 20 years.
James Jesus Angleton also took him seriously, as did certain wings within MI5. His original book, "New Lies For Old," was just too damn scary ... even if largely on the money.
The KGB managed to infiltrate and hobble the CIA by driving Angleton nuts, and dividing the company into two camps: (1) 1 believing in a false defector (2) the other knowing the guy was a phony, but being unable to prove it. It took them 10 years, but by the time Jimmy was President, and another nutjob, Stansfield Turner, who did not value "HUMINT" took over the CIA for him, the KGB plan was complete and the CIA became seriously weakened.
It is still in a weakened state because many of the leftish fools put in high places by the Turner regime are still there. Golytsin, having been a confidant of Angleton's, is an annoyance to the powers that be at the CIA. Both were right then, and Golystsin still is, but they lost.
IMHO, Golytsin is telling us that Communism is not dead, it is resting and re-arming, while hoping the west goes to sleep... again, and that there is no real split between China and Russia. Of course, we didn't need him to tell us that the KGB worked hand-in-glove with the forces of Islamic terrorism.
