U.S. Secretly Aids Pakistan in Guarding Nuclear Arms

WASHINGTON, Nov. 17 — Over the past six years, the Bush administration has spent almost $100 million on a highly classified program to help Gen. Pervez Musharraf, Pakistan’s president, secure his country’s nuclear weapons, according to current and former senior administration officials.

While American officials say that they believe the arsenal is safe at the moment, and that they take at face value Pakistani assurances that security is vastly improved, in many cases the Pakistani government has been reluctant to show American officials how or where the gear [nuclear security systems]  is actually used.
