petr,

Absolutely granted, what I have said regarding Dr. Khan is only assumption on my part, I think that was clear in my original post on the subject.

I believe having read somewhere that it was documentation received from the Libyan disarmament programme that "blew the whistle" on the unoficial activities of A. Q. Khan.

Let me ask you, do you believe that the US and IAEA, said and did nothing regarding those activities. You seem to be all too well prepared to believe that the current US administration "does deals" and engages in under-cover operations, whenever such activities can be construed in a negative light - but not when they may be for the good.
