This book, a follow-up publication to the 2016 volume Foreign Fighters under International Law and Beyond, zooms in on the responses that the international community and individual States are implementing in response to (prospective and actual) returning foreign fighters (FFs) and their families, focusing on returnees from Syria and Iraq to European countries.  As States and international organisations are still ‘learning by doing’, the role of the academic community is to help steer the process by bridging the divide between international standards and their implementation at the national level and between security concerns and human rights law. Furthermore, the academic community can and should assist in identifying ways forward that are both effective, sustainable and international law-compliant. Those are, ultimately, the goals that the present volume seeks to pursue.  The observations, recommendations and warnings included in this book will be useful in future debates on (returning) FFs, both in the academic world and in the world of policy makers and practitioners, as well as to the public at large.

Volume 24 of the Yearbook of International Humanitarian Law (IHL) is dedicated to investigating IHL's universalist claims from different perspectives and regarding different areas of IHL. While academic debates about "universalism versus particularism" have dominated much of the critical scholarship in international law over the past two decades, they remain relatively underexplored in the field of IHL. The current volume fills this gap in IHL literature by focusing on the ways in which different interpretive communities approach questions of IHL from differing perspectives. Authors were invited to use the concept of culture to deconstruct and take critical distance from the production, interpretation, and application of IHL, and those keen on challenging the idea that IHL needs critical deconstruction were also invited to argue their case. The Volume contains four articles dedicated to the subject of cultures of IHL. It also features a book symposium on Samuel Moyn's Humane: How The United States Abandoned Peace and Reinvented War (2021) and ends, as usual, with a Year in Review section. The Yearbook of International Humanitarian Law is a leading annual publication devoted to the study of international humanitarian law. The Yearbook has always strived to be at the forefront of the debate of pressing doctrinal questions of IHL and will continue to do so in the future. As this volume shows, it is also a forum for taking a step back and reflecting on the broader, theoretical issues that inform the practice and thinking about the field. The Yearbook provides an international forum for high-quality, peer-reviewed academic articles focusing on this crucial branch of international law. Distinguished by contemporary relevance, it bridges the gap between theory and practice and serves as a useful reference tool for scholars, practitioners, military personnel, civil servants, diplomats, human rights workers and students.

This volume of the Yearbook of International Humanitarian Law takes a close look at the role of so-called "expert manuals" in the interpretation and development of the international law of armed conflict and connected branches of international law relating to military operations. While these manuals can and do play an undoubtedly useful role, their proliferation raises a number of questions. What degree of authority do they have and how much weight should be given to the views expressed in them? What is the methodology they employ and how effective is it in ensuring an as objective and impartial interpretation of the law as possible? What is their place in the doctrine of sources? While there is already a considerable body of literature addressing these and other relevant questions, this volume aims to contribute further to this discussion with contributions by three experts involved in one or more of these manuals in one capacity or another. Alongside these three contributions on this year's special theme, the second part of the book comprises three chapters that address timely and relevant issues of International Humanitarian Law. These range from starvation as a method of warfare, to emerging technologies of warfare, and also includes reflections on humanitarian assistance. Lastly, the volume concludes with the Year in Review, describing the most important armed conflict-related events and legal developments that took place in 2020. The Yearbook of International Humanitarian Law is a leading annual publication devoted to the study of international humanitarian law. It provides a truly international forum for high-quality, peer-reviewed academic articles focusing on this crucial branch of international law. Distinguished by contemporary relevance, the Yearbook of International Humanitarian Law bridges the gap between theory and practice and serves as a useful reference tool for scholars, practitioners, military personnel, civil servants, diplomats, human rights workers and students.

Through an analysis of the use of drones, Rebecca Mignot-Mahdavi explores the ways in which, in the context of counterterrorism, war, technology and the law interact and reshape one another. She demonstrates that drone programs are techno-legal machineries that facilitate and accelerate the emergence of a new kind of warfare. This new model of warfare is individualized and de-materialized in the sense that it focuses on threat anticipation and thus consists in identifying dangerous figures (individualized warfare) rather than responding to acts of hostilities (material warfare). Revolving around threat anticipation, drone wars endure over an extensive timeframe and geographical area, to the extent that the use of drones may even be seen, as appears to be the case for the United States, as part of the normal functioning of the state, with profound consequences for the international legal order.
