I could have stopped it after they paid me the $50,000. I wouldn't even have had to go on to do more than I already had: just the double agents' names that I gave.

I found that our Soviet espionage efforts had virtually never, or had very seldom, produced any worthwhile political or economic intelligence on the Soviet Union.

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.

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.

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

Espionage, for the most part, involves finding a person who knows something or has something that you can induce them secretly to give to you. That almost always involves a betrayal of trust.
