Jason Burke is one of the world’s leading experts on militant Islam. He embedded with the Kurdish peshmerga (currently at war with ISIS) while still in college. He was hanging out with the Taliban in the late 1990s. He witnessed the bombing of Tora Bora in Afghanistan in 2001 firsthand.With the current emergence of ISIS in Iraq and Syria and the resurgence of the Taliban in Afghanistan and Pakistan, no one is as well placed as Burkewhose previous books have been chosen as books of the year byThe Economist, theDaily Telegraph, andThe Independentto explain this dramatic postAl Qaeda phase of Islamic militancy. We are now, he argues, entering a new phase of radical violence that is very different from what has gone before, one that is going to redefine the West’s relationship with terrorism and the Middle East.ISIS is not medieval,” as many U.S. national security pundits claim, but, Burke explains, a group whose spectacular acts of terror are a contemporary expression of our highly digitized societies, designed to generate global publicity. In his account, radical Islamic terrorism is not an aberration or cancer,” as some politicians assert; it is an organic part of the modern world. This book will challenge the preconceptions of many American readers and will be hotly debated in national security circles.
