Bush thanked Musharraf for working with the United States to break up the Khan nuclear network and urged him to "make sure we're getting every nook and cranny in this global network," the senior official said. Musharraf assured Bush that it was in Pakistan's interest to do so and that "he's going to go back and make sure his people are figuring out if they've gotten everything," the official said.
The U.S. official said the administration was not frustrated because it had obtained "a treasure-trove" of intelligence from Pakistan on Khan's activities, and added, "We would never have known about it had it not been for President Musharraf's decision to crack down internally on these guys."
Pakistan has disclosed to the United States the activities that Khan engaged in without authorization from his handlers, Tellis said. "But Musharraf for obvious institutional reasons has not come clean on the Pakistani military's complicity in what A.Q. Khan was doing, and we have not pushed him on that because it is a bridge too far."
