The Threat from Within: Recognizing Al Qaeda-Inspired Radicalization and Terrorism in the West

The Threat From Within examines what drives Al Qaeda-inspired radicalization to violence, how to detect it, and how to confront it. The chapters discuss behaviors and ideologies that are observable and tangible in radicalized individuals or those on the path to violent radicalization. These behaviors are drawn from a variety of cases, such as planning acts of terrorism, traveling to join terrorist groups, or participating in violent jihadi conflict outside the country. The main case study is Canada, and each chapter features many examples that range from Ted Kaczynski (the ＂Unabomber＂) and Anders Brevik in Norway to Tamerlan Tsarnaev and Damian Clairmont, a Canadian citizen who died fighting in Syria. The text begins by introducing general concepts, such as terrorism, extremism, and radicalization, before presenting contributing factors to those embracing political violence. A comprehensive list of behavioral indicators that someone is becoming a violent extremist is provided, followed by a look at what is being done to confront this threat as well as what could be done.
