The Hoover Institution's National Security, Technology and Law Working Group, along with Hoover's Washington, DC office held a discussion with author of The Way of Strangers, Graeme Wood. Hoover working group member and senior fellow at the Brookings Institution Benjamin Wittes, along with Samuel Tadros, distinguished visiting fellow at the Hoover Institution, interviewed Wood, who discussed his definitive, electrifying account of the strategy, psychology, and theology driving the Islamic State. The Way of the Strangers is an intimate journey into the minds of the Islamic State's true believers. From the streets of Cairo to the mosques of London, Graeme Wood interviews supporters, recruiters, and sympathizers of the group. We meet an Egyptian tailor who once made bespoke suits for Paul Newman and now wants to live, finally, under Shariah; a Japanese convert who believes that the eradication of borders-one of the Islamic State's proudest achievements-is a religious imperative; and a charming, garrulous Australian preacher who translates the group's sermons and threats into English and is accused of recruiting for the organization. We also learn about a prodigy of Islamic rhetoric, now stripped of the citizenship of the nation of his birth and determined to see it drenched in blood. Wood speaks with non-Islamic State Muslim scholars and jihadists, and explores the group's idiosyncratic, coherent approach to Islam. The Islamic State is bent on murder and apocalypse, but its followers find meaning and fellowship in its utopian dream. Its first caliph, Abu Bakr al Baghdadi, has declared that he is the sole legitimate authority for Muslims worldwide. The theology, law, and emotional appeal of the Islamic State are key to understanding it-and predicting what its followers will do next. Through character study and analysis, Wood provides a clear-eyed look at a movement that has inspired so many people to abandon or uproot their families. Many seek death-and they will be the terror threat of the next decade, as they strike back against the countries fighting their caliphate. Just as Lawrence Wright's The Looming Tower informed our understanding of Al Qaida, Graeme Wood's The Way of the Strangers will shape how we see a new generation of terrorists.
