With allies like Pakistan how can the US end the war in Afghanistan?
Publicly, the U.S. credits Pakistan with helping kill and capture many al-Qaida and Taliban leaders. Privately, the relationship is often marked by mistrust and double-dealing as Pakistan runs double agents against the CIA and the agency tries to penetrate Pakistan's closely guarded nuclear program.
Spying among friends is old news in the intelligence business, but the U.S.-Pakistan relationship is at the heart of Washington's counterterrorism efforts. Any behind-the-scenes trickery could undermine those efforts as well as the long-standing hunt for Osama bin Laden.
