In late August, a couple of weeks after a U.S. drone strike incinerated Baitullah Mehsud, leader of the Pakistani Taliban, the country’s most popular televised chat show, “Capital Talk,” hosted a panel to discuss national security. Among the guests was a squat, middle-aged woman with short black hair, streaked with silver dye, named Shireen Mazari. A defense analyst and public intellectual, Mazari is known for her hawkish nationalism--and deep suspicions of India and the United States. Her presence in the studio suggested that, despite the enormous threat her country faced from homegrown terrorists, the conversation that night wouldn’t center around Mehsud or the Pakistani Taliban.

Within a few minutes of Noman Benotman's arrival at the Kandahar guest house, Osama bin Laden came to welcome him. The journey from Kabul had been hard, 17 hours in a Toyota pickup truck bumping along what passed as the main highway to southern Afghanistan. It was the summer of 2000, and Benotman, then a leader of a group trying to overthrow the Libyan dictator Muammar Qaddafi, had been invited by bin Laden to a conference of jihadists from around the Arab world, the first of its kind since Al Qaeda had moved to Afghanistan in 1996.
