About the Book:Terrorist organizations and international criminal networks pose an increasingly severe danger to US security. Who are these rivals who threaten us? What do they want to achieve? This book looks at diverse groups such as Al Qaeda, its jihadist fellow travelers as well as Hezbollah and its terrorist sponsor, Iran. Other chapters examine Hamas, Jemaah Islamiyah, the FARC, the Mexican drug cartels, and the criminal gang, Mara Salvatrucha 13. Pakistan, where jihadists pose an extreme security threat, is another focus as is a chapter on terrorist WMD threats. This look at sub-state rivals is recommended to all serious students of international security.
