By the late '70s I had come to question the point of a great deal of what we were doing, in terms of the CIA's overall charter.

The FBI, to its credit in a self-serving sort of way, rejects the routine use of the polygraph on its own people.

The betrayal of trust carries a heavy taboo.

I saw a limit to what I was giving as kind of a scam I was running on the KGB, by giving them people that I knew were their double agents fed to us.

I came into the Agency with a set of ideas and attitudes that were quite typical of people coming into the Agency at that time. You could call it liberal anti-communism.

Foreign Ministry guys don't become agents. Party officials, the Foreign Ministry nerds, tend not to volunteer to Western intelligence agencies.

Historians don't really like to carry on speculative debates, but you could certainly argue that the likelihood of a Soviet invasion of Western Europe was extremely, extremely low.
