The Soviet Union did not achieve victory over the West, so was my information inadequate to help them to victory, or did it play no particular role in their failure to achieve victory?

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.

When Reagan was elected, I felt that the Agency had gone much more into the service of a political tendency in the country with which I had already felt very strong disagreement.

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.

Let's say a Soviet exchange student back in the '70s would go back and tell the KGB about people and places and things that he'd seen and done and been involved with. This is not really espionage; there's no betrayal of trust.

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.

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.
