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.

The use of the polygraph has done little more than create confusion, ambiguity and mistakes.

My little scam in April '85 went like this: Give me $50,000; here's some names of some people we've recruited.

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.

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

The betrayal of trust carries a heavy taboo.

I'm a traitor, but I don't consider myself a traitor.
