From the old gray lady:
Also at stake is the C.I.A.’s armed drone program, which has carried out hundreds of strikes in Pakistan in recent years and has killed several senior operatives from Al Qaeda and the Pakistani Taliban. Pakistan has threatened to expel C.I.A. operatives working on the drone program from a base in southern Pakistan, and the C.I.A. has set up contingency plans to run more flights from a base in eastern Afghanistan.
