During the post-cold war world, the world's only superpower has encountered an unprecedented challenge: a non-state enemy that is challenging its hegemony and is using violence as a strategic means. Given the international nature of this phenomenon, a structured explanation such as this is given added necessity and urgency. Cornelia Beyer provides a structured explanation for terrorism and its links with the 'Global War on Terror' as it relates to the latter's broader context, causes and implications. She offers a comprehensive understanding of the phenomenon of international terrorism and proposes effective policies to counter it. She also remedies the current undertheorized nature of the subject area, and in doing so opens up new modes of thinking about and struggling against global terrorism.
