In 2011, Ayman al-Zawahiri succeeded Osama bin Laden as head of al-Qaeda, a position he held until he was killed by a U.S. drone strike in July 2022. In his upcoming book, Doctor, Teacher, Terrorist: The Life and Legacy of Al-Qaeda Leader Ayman al-Zawahiri, Dr. Sajjan Gohel, International Security Director at the Asia-Pacific Foundation, provides the first definitive account of one of the world’s most wanted terrorists. In conversation with Museum Director Clifford Chanin, Gohel details the life of al-Zawahiri, his deadly legacy, and the history and future of al-Qaeda.
