When the United States learned in 2001 that Pakistani scientists had shared nuclear secrets with members of al-Qaeda, an alarmed Bush administration responded with tens of millions of dollars worth of equipment such as intrusion detectors and ID systems to safeguard Pakistan's nuclear weapons.

But Pakistan remained suspicious of U.S. aims and declined to give U.S. experts direct access to the half-dozen or so bunkers where the components of its arsenal of about 50 nuclear weapons are stored. For the officials in Washington now monitoring Pakistan's deepening political crisis, the experience offered both reassurance and grounds for concern.
