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

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.

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.

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

You might as well ask why a middle-aged man with no criminal record might put a paper bag over his head and rob a bank. I acted out of personal desperation.

No one's interested really in knowing what policies or diplomatic initiatives or arms negotiations might have been compromised by me.

The betrayal of trust carries a heavy taboo.
