Wars from Within brings together an international and multidisciplinary group of academics and practitioner-researchers specializing in the study of insurgent movements in order to provide a deeper understanding of the violent manifestations of insurgencies in different parts of the world. In doing so, the book adopts both a functional and regional approach. Firstly, thematic chapters discuss the typology of insurgencies (ethnopolitical, religious and ideological), past and potential responses to them, as well as the impact of advance communication technology on insurgent activity. The book then presents a series of case studies assessing the successes and failures of managing contemporary insurgencies. These are drawn from European, Asian and Middle Eastern insurgencies, as well as the global al-Qaeda network that typifies the post-9/11 challenge posed by internationally operating terrorist organizations. The case studies highlight factors and conditions that trigger, escalate, de-escalate and ultimately end insurgent campaigns. The book concludes with an assessment of how the international community at large has responded and should respond to insurgencies in the future.
