States' Responses to the Foreign Terrorist Fighters Phenomenon : Shunning Responsibilities, Shifting Risks and the Limits of Public International Law (Leiden Studies on the Frontiers of International Law)

Following the outbreak of the Syrian Civil War in 2011, tens of thousands of foreigners traveled to Syria and Iraq to join the Islamic State and other terrorist organizations. These individuals have been referred to as ‘foreign terrorist fighters’ (FTFs). What made the mobilization of such individuals unprecedented was, among other reasons, the extraordinary far-reaching responses by their states of origin. This book focuses on four such responses: (1) prevention of travel, (2) nationality deprivation, (3) (non-)repatriation, and (4) prosecution. It argues that, through these responses, states have essentially shunned their responsibilities and shifted security risks, as well as a burden to counter such risks, to other states. Such practices of pushing away burdens, responsibilities, threats and people perceived as unwanted are, however, neither new nor specific to the FTFs phenomenon, but are rather part of a broader pattern. Using the FTFs phenomenon in Syria and Iraq as a case study, this book explores the extent to which public international law governs the shunning of responsibilities and the shifting of security risks, as visible in states’ responses to this phenomenon.
