Answer:
Pakistan's possession of nuclear weapons concerns the United States because Pakistan's chief nuclear scientist has shared information with other states.
Explanation:
It is rumored that Pakistan has transferred several nuclear weapons to Saudi Arabia, but this is not confirmed. In March 2006, the German magazine Cicero reported that Saudi Arabia had received assistance from Pakistan since 2003 to acquire nuclear missiles and warheads. Satellite photos allegedly reveal an underground city and nuclear silos with Agni-II rockets south of the capital Riyadh. Pakistan has denied helping Saudi Arabia in any nuclear ambitions.
It is also suspected that the Pakistani government has provided nuclear weapons to the defunct regime of Muammar Gaddafi in Libya.
