This book offers various perspectives, with an international legal focus, on an important and underexplored topic, which has recently gained momentum: the issue of foreign fighters. It provides an overview of challenges, pays considerable attention to the status of foreign fighters, and addresses numerous approaches, both at the supranational and national level, on how to tackle this problem. Outstanding experts in the field – lawyers, historians and political scientists – contributed to the present volume, providing the reader with a multitude of views concerning this multifaceted phenomenon. Particular attention is paid to its implications in light of the armed conflicts currently taking place in Syria and Iraq.

Foreign Fighters is the comprehensive study of foreign fighters examines patterns of recruitment using original data sets and detailed diverse case studies, and how recruiters use frames of existential threat to strengthen rebel groups.

The term ‘foreign fighters’ describes nationals of one state who – for whatever variety of reasons and motives – travel abroad to take part in a conflict in another state without the promise of financial reward. The majority of attention has so far been focused on the nationals of Western European states who have gone to fight for the so-called Islamic State in Syria. There exist, however, other examples of contemporary European foreign fighters whose travails, motivations and returns have been largely unnoticed and underappreciated. This books attempts to balance this state of affairs by bringing to the fore some lesser known cases of non-terrorist but foreign fighters related to the conflict in Ukraine, and situating them against the backdrop of the larger mobilization for the war in Syria. This book presents edited versions of the 12 papers presented at the NATO Advanced Research Workshop (ARW) ‘Not Only Syria? Foreign Fighters: A Threat to NATO Allies and Their Neighbours’. The workshop was held in Chisinau, Moldova, in May 2016, and brought together researchers and experts in the field to discuss the differences, similarities and parallels between different groups of foreign fighters engaged in the conflicts in Syria and the Ukraine. The papers include contributions from the Netherlands, Belgium, Denmark and Poland among others, and examine cases of foreign fighters from these and other countries. The book will provide an interesting context to researchers who have, up to now, looked only at a single set of such fighters, and will lead to tangible recommendations on how to develop policies to address the threat posed by returnees from any conflict.

In this book, it is explained that despite a current drop in the number of deaths, terrorism should still be considered a serious and widespread problem. However, the responses to this phenomenon are often more problematic from a long-term perspective. With the human rights framework under serious pressure, this edited volume offers a timely, important and critical in-depth analysis of human dignity and human security challenges in the lead-up, and in the responses, to current forms of terrorism. It aims to map how human dignity and human security can be secured and how law can constitute a source of trust at a time when Europe and the rest of the world continue to be plagued by terrorism. The authors are both established names and upcoming talent in this fastchanging and exciting field of law. They thoroughly analyse a variety of topical subjects, in more conceptual chapters—for example calling for the humanisation of the security discourse—and in highly practical contributions, in which for instance the Kafkaesque situation in which rendition and torture victim Abu Zubaydah still finds himself today is considered. This book, which focuses on, but is not limited to the situation in Western countries, aims to inspire not only academics—through further theorisation on the sometimes elusive but important concepts of human dignity and human security—but also practitioners working in the field of countering terrorism. It will hopefully convince them (even more) that following a human rights approach will be indispensable in securing human dignity and human security for all. Even—or in fact: especially—in times of terrorism. Christophe Paulussen is a Senior Researcher in the Research Department of the T.M.C.

Which law applies to armed conflict? This book investigates the applicability of international humanitarian law and international human rights law to armed conflict situations. The issue is examined by three scholars whose professional, theoretical, and methodological backgrounds and outlooks differ greatly. These multiple perspectives expose the political factors and intellectual styles that influence scholarly approaches and legal answers, and the unique trialogical format encourages its participants to decenter their perspectives. By focussing on the authors' divergence and disagreement, a richer understanding of the law applicable to armed conflict is achieved. The book, firstly, provides a detailed study of the law applicable to armed conflict situations. Secondly, it explores the regimes' interrelation and the legal techniques for their coordination and prevention of potential norm conflicts. Thirdly, the book moves beyond the positive analysis of the law and probes the normative principles that guide the interpretation, application and development of law.

This book comprises contributions by leading experts in the field of international humanitarian law on the subject of the categorisation or classification of armed conflict. It is divided into two sections: the first aims to provide the reader with a sound understanding of the legal questions surrounding the classification of hostilities and its consequences; the second includes ten case studies that examine practice in respect of classification. Understanding how classification operates in theory and practice is a precursor to identifying the relevant rules that govern parties to hostilities. With changing forms of armed conflict which may involve multi-national operations, transnational armed groups and organized criminal gangs, the need for clarity of the law is all-important. The case studies selected for analysis are Northern Ireland, DRC, Colombia, Afghanistan (from 2001), Gaza, South Ossetia, Iraq (from 2003), Lebanon (2006), the so-called war against Al-Qaeda, and future trends. The studies explore the legal consequences of classification particularly in respect of the use of force, detention in armed conflict, and the relationship between human rights law and international humanitarian law. The practice identified in the case studies allows the final chapter to draw conclusions as to the state of the law on classification.

This book examines the attempts by the international community and the United Nations to define and criminalise terrorism. In doing so, it explores the difficult legal, ethical and philosophical questions involved in deciding when political violence is, or is not, permissible.
