ISIS shocked many when it rose to prominence in 2014 announcing a caliphate in Syria and Iraq. It took years to defeat them but understanding the rise of the organization goes many years back. To help us understand the origins of ISIS, we interview Joby Warrick who is a National security reporter for the Washington Post covering terrorism, rogue states, weapons proliferation. He is the author of two books, including 2015’s “Black Flags: The Rise of ISIS,” which was awarded a 2016 Pulitzer Prize for nonfiction. His first book, “The Triple Agent,” recounts the 2009 suicide attack by an al-Qaeda informant on a CIA base at Khost, Afghanistan, that killed seven U.S. intelligence operatives. Before joining The Post, he covered the fall of communism in Eastern Europe as a UPI correspondent and worked as a reporter at the Delaware County (Pa.) Daily Times, the Philadelphia Inquirer and the News & Observer of Raleigh, N.C. We examine the organizations origin, its leaders, and how it rose to prominence and shocked many across the world.
