This book sheds new light on the security challenges for failed states posed by violent non-state armed actors (VNSAs). By focusing on the Syrian Civil War, it explores the characteristics, ideologies and strategies of the Islamic State (ISIS) and the People's Protection Units (YPG), as well as the regional and geopolitical impacts of these VNSAs. The contributors also cover topics such as the re-imagination of borders, the YPG's demands for national sovereignty, and the involvement of regional and global powers in the Syrian crisis.

Part I : Actorness -- Part II : Powerfulness -- Part III : Effectiveness.
