Seymour Hersh is an American investigative journalist who is the recipient of many awards, including the Pulitzer Prize for his article exposing the My Lai massacre by the U.S. military in Vietnam. More recently, he exposed the U.S. government's abuse of detainees in the Abu Ghraib prison facility.

Hersh's new book, The Killing of Osama Bin Laden, is a corrective to the official account of the war on terror. Drawing from accounts of a number of high-level military officials, Hersh challenges a number of commonly accepted narratives: that Syrian president Bashar al-Assad was responsible for the Sarin gas attack in Ghouta; that the Pakistani government didn't know Bin Laden was in the country; that the late ambassador J. Christopher Stevens was at the U.S. consulate in Benghazi in a solely diplomatic capacity; and that Assad did not want to give up his chemical weapons until the U.S. called on him to do so.
