Winner, 2022 Nellie Bly Book Award, Chanticleer International Book Awards More than a decade ago, counterterrorism expert Rita Katz began browsing white supremacist and neo-Nazi forums. The hateful rhetoric and constant threats of violence immediately reminded her of the jihadist militants she spent her days monitoring, but law enforcement and policy makers barely paid attention to the Far Right. Now, years of attacks committed by extremists radicalized online—including mass murders at a synagogue in Pittsburgh and mosques in Christchurch, New Zealand, as well as the Capitol siege—have brought home the danger. How has the internet shaped today’s threats, and what do the online origins of these movements reveal about how to stop them? In Saints and Soldiers, Katz reveals a new generation of terrorist movements that don’t just use the internet, but exist almost entirely on it. She provides a vivid view from the trenches, spanning edgy video game chat groups to what ISIS and Far-Right mass-shooters in El Paso, Orlando and elsewhere unwittingly reveal between the lines of their manifestos. Katz shows how the online cultures of these movements—far more than their ideologies and leaders—create today’s terrorists and shape how they commit “real world” violence. From ISIS to QAnon, Saints and Soldiers pinpoints the approaches needed for a new era in which arrests and military campaigns alone cannot stop these never-before-seen threats.
