Terrorist attacks and acts of violence generally pursue a common goal: they aim to shake, shock, and intimidate. Terrorism seeks the public's attention. Accordingly, this book understands terrorism as a communication strategy. Philip Weissermel compares the very different terrorist organizations, the Red Army Faction (RAF) and the Islamic State (IS), and examines the key question of whether and what similarities exist between the communication strategies of both terrorist organizations, regardless of their ideologies. Furthermore, the symbiosis of terrorism and mass media is highlighted. Through the use of cutting-edge technologies, terrorists have adopted innovative communication methods. They operate as learning terrorist networks that closely monitor the media and audience impact of their violent acts and publications.
