You say Alibek convinced Pasechnik to defect. I don't deny that that's possible. According to Alibek's account in his book, he did approve Pasechnik's trip abroad, on which he defected. But Alibek claims he was totally unaware of Pasechnik's plan to defect. Is there evidence that Alibek was involved in the defection -- which preceded Alibek's (the book gave me the impression that the two defections were a couple of years apart)?
We are playing with words here. I could do or say something rather unintentionally that would convince you to defect.
In any case, I have always been under the impression Ken left first, or at least made up his mind about what he had to do first. Am I in error? If so, that's readily corrected.
There are folks who think Ken defected just for a higher income. There are others who say he did it out of principle. My own thought is that he found himself in a rather dangerous place and needed no esoteric reasons to leave it!
