The only thing I ever withheld from the KGB were the names of two agents whom I personally had known and handled and had a particular feeling for.

The difficulties of conducting espionage against the Soviet Union in the Soviet Union were such that historically the Agency had backed away from the task.

The national security state has many unfair and cruel weapons in its arsenal, but that of junk science is one which can be fought and perhaps defeated.

The human spy, in terms of the American espionage effort, had never been terribly pertinent.

Perhaps my information hurt the Soviet Union more than it helped. I have no idea. It was not something I ever discussed with the KGB officers that I was dealing with.

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.

The resistance of policy-makers to intelligence is not just founded on an ideological presupposition. They distrust intelligence sources and intelligence officials because they don't understand what the real problems are.
