Malcolm Nance, a 34-year veteran intelligence officer who has worked the Iraq mission since 1987, fighting in all of our Middle East wars since 1983. He has lived in and out of Iraq since 2003. The death of former Saddam General Izzat Ibrahim al-Douri last week provides an opportunity to ask Nance about who the insurgent commander was, how he evaded capture or death for so many years, and what the hell is really going on in Iraq. In addition to his time on the ground, Nance has written defense intelligence textbooks on the subject—books that are occasionally dense but “are exhaustively detailed for a reason,” he says. “I am not here to entertain, but to share hard intelligence, won by the blood of dead soldiers, sailors, airmen, marines and intelligence officers and explain the deep history of these groups which leads you to ISIS.” He is not shy about the why of knowing: So that “we kill the right people with what we learned.” Nance runs his own analytical organization, TAPSTRI, the Terror Asymmetrics Project and is author of, most recently, The Terrorists of Iraq: Inside the Strategy and Tactics of the Iraq Insurgency, 2003-2014.
