The Death of Ayman al-Zawahiri

In 2002, when I profiled Ayman al-Zawahiri for The New Yorker, he was called "the man behind bin Laden." But since bin Laden was killed by American special forces in 2011, Zawahiri has been Al Qaeda's leader. Zawahiri and bin Laden were very different men, not friends but allies, using each other for the skills and resources they could each provide. Al Qaeda would not have survived without the dynamic they created together. Zawahiri, reportedly killed in Afghanistan by a U.S. drone strike over the weekend, was a doctor--a highly-educated professional who chose to devote himself to violent revolution.
