The Islamic State, known as ISIS, exploded into the public eye in 2014 with startling speed and shocking brutality. It has captured the imagination of the global jihadist movement, attracting recruits in unprecedented numbers and wreaking bloody destruction with a sadistic glee that has alienated even the hardcore terrorists of its parent organization, al Qaeda.Jessica Stern and J.M. Berger, two of America's leading experts on terrorism, dissect the new model for violent extremism that ISIS has leveraged into an empire of death in Iraq and Syria, and an international network that is rapidly expanding in the Middle East, North Africa and around the world.ISIS: The State of Terror traces the ideological innovations that the group deploys to recruit unprecedented numbers of Westerners, the composition of its infamous snuff videos, and the technological tools it exploits on social media to broadcast its atrocities, and its recruiting pitch to the world, including its success at attracting thousands of Western adherents. The authors examine ISIS's predatory abuse of women and children and its use of horror to manipulate world leaders and its own adherents as it builds its twisted society. The authors offer a much-needed perspective on how world leaders should prioritize and respond to ISIS's deliberate and insidious provocations.
