That epitomizes this AQ Kahn affair, there is always "a little more" to be learned, but it comes only in hints, innuendos and subtle clues. What obscures the deepest secrets is all the public hand wringing and gnashing of teeth over whether Mushi knew of or profited from the affair. But that is probably the least important aspect of this whole sordid business. I suspect that both the U.S. and Pakistan promote that part of the controversy just to keep the media and public from focusing on the heart of the matter, so that it can be handled with less difficulty, privately.
Most people are unaware that virtually all the important details of the AQ Kahn affair were public knowledge (in books and on the internet) long before the story became a page one issue. The same is true regarding the Saudi involvement in the Paki nuclear weapons program, but that aspect of the Paki nuclear proliferation is just not part of page one news....at least not yet.
