This book addresses the regulation of hybrid warfare under relevant branches of international law, beginning with the law on inter-state use of force (jus ad bellum). Firstly, the book assesses the extent to which forms of hybrid warfare comply with or violate international humanitarian law/the law of armed conflict. It then looks at law enforcement action in response to hybrid warfare, both on land and on the high seas, and addresses hybrid warfare from the perspective of international counterterrorism law. It goes on to tackle the constraints applied to hybrid warfare under international human rights law, and looks at how hybrid warfare could be constrained under disarmament law. The final two chapters look at accountability for the conduct of hybrid warfare, concluding with the question: can we move towards a less fragmented set of international legal rules that will govern hybrid warfare in the future?

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.

Hybrid warfare has been an integral part of the historical landscape since the ancient world, but only recently have analysts - incorrectly - categorised these conflicts as unique. Great powers throughout history have confronted opponents who used a combination of regular and irregular forces to negate the advantage of the great powers' superior conventional military strength. As this study shows, hybrid wars are labour-intensive and long-term affairs; they are difficult struggles that defy the domestic logic of opinion polls and election cycles. Hybrid wars are also the most likely conflicts of the twenty-first century, as competitors use hybrid forces to wear down America's military capabilities in extended campaigns of exhaustion. Nine historical examples of hybrid warfare, from ancient Rome to the modern world, provide readers with context by clarifying the various aspects of conflicts and examining how great powers have dealt with them in the past.

Place is inextricably linked to history by way of culture, language, philosophy, faith and the development of worldviews. The richness and depth of experience of the Asia-Pacific region has been under-studied, over-simplified and under-appreciated. This book addresses that lacuna in the subject area of international humanitarian law. Drawing on authoritative perspectives and interviews with experts in and on this topic, including four of the region's most distinguished international judges, forty-one chapters thematically examine the development of international humanitarian law; practice and application of international humanitarian law; implementation and enforcement of international humanitarian law; and looking to the future and enhancing compliance with international humanitarian law. The expert contributors draw out unique features, providing fresh insights to scholarship. Contributions on and from the area also grapple with the regional commitments to humanitarianism generally, illuminating how and why international humanitarian law might be more readily accepted or ignored in armed conflicts in the region.

This book provides the first comprehensive analysis of factors that transform a prima facie non-international armed conflict (NIAC) into an international armed conflict (IAC) and the consequences that follow from this process of internationalization. It examines in detail the historical development as well as the current state of the relevant rules of international humanitarian law. The discussion is grounded in general international law, complemented with abundant references to case law, and illustrated by examples from twentieth and twenty-first century armed conflicts. In Part I, the book puts forward a thorough catalogue of modalities of conflict internationalization that includes outside intervention, State dissolution, and recognition of belligerency. It then specifically considers the legal qualification of complex situations that feature more than two conflict parties and contrasts the mechanism of internationalization of armed conflicts with the reverse process of de-internationalization. Part II of the book challenges the conventional wisdom that members of non-State armed groups do not normally benefit from combatant status. It argues that the majority of fighters belonging to non-State armed groups in most types of internationalized armed conflicts are in fact eligible for combatant status. Finally, Part III turns to belligerent occupation, traditionally understood as a leading example of a notion that cannot be transposed to armed conflicts occurring in the territory of a single State. By contrast, the book argues in favour of the applicability of the law of belligerent occupation to internationalized armed conflicts.

This book provides a modern and basic introduction to a branch of international law constantly gaining in importance in international life, namely international humanitarian law (the law of armed conflict). It is constructed in a way suitable for self-study. The subject-matters are discussed in self-contained chapters, allowing each to be studied independently of the others. Among the subject-matters discussed are, inter alia: the Relationship between jus ad bellum / jus in bello; Historical Evolution of IHL; Basic Principles and Sources of IHL; Martens Clause; International and Non-International Armed Conflicts; Material, Spatial, Personal and Temporal Scope of Application of IHL; Special Agreements under IHL; Role of the ICRC; Targeting; Objects Specifically Protected against Attack; Prohibited Weapons; Perfidy; Reprisals; Assistance of the Wounded and Sick; Definition of Combatants; Protection of Prisoners of War; Protection of Civilians; Occupied Territories; Protective Emblems; Sea Warfare; Neutrality; Implementation of IHL.

“Brutally honest... a deeply extraordinary and original work.” - SEBASTIAN JUNGER. With an estimated 250,000 people killed in 15 years, the Mexican drug war is the most violent conflict in the Western world. It shows no sign of abating. In this book, Dr Teun A. Voeten analyzes the dynamics of the violence. He argues it is a new type of war called hybrid warfare: multidimensional, elusive and unpredictable, fought at different levels, with different intensities with multiple goals. The war ISIS has declared against the West is another example of hybrid warfare. Voeten interprets drug cartels as ultra-capitalist predatory corporations thriving in a neoliberal, globalized economy. They use similar branding and marketing strategies as legitimate business. He also looks at the anthropological, individual level and explains how people can become killers. Voeten compares Mexican sicarios, West African child soldiers and Western jihadis and sees the same logic of cruelty that facilitates perpetrating ‘inhumane’ acts that are in fact very human.

During the last decade, 'Hybrid Warfare' has become a novel yet controversial term in academic, political and professional military lexicons, intended to suggest some sort of mix between different military and non-military means and methods of confrontation. Enthusiastic discussion of the notion has been undermined by conceptual vagueness and political manipulation, particularly since the onset of the Ukrainian Crisis in early 2014, as ideas about Hybrid Warfare engulf Russia and the West, especially in the media. Western defense and political specialists analyzing Russian responses to the crisis have been quick to confirm that Hybrid Warfare is the Kremlin's main strategy in the twenty-first century. But many respected Russian strategists and political observers contend that it is the West that has been waging Hybrid War, Gibridnaya Voyna, since the end of the Cold War. In this highly topical book, Ofer Fridman offers a clear delineation of the conceptual debates about Hybrid Warfare. What leads Russian experts to say that the West is conducting a Gibridnaya Voyna against Russia, and what do they mean by it? Why do Western observers claim that the Kremlin engages in Hybrid Warfare? And, beyond terminology, is this something genuinely new?

The third edition of this work sets out a comprehensive and analytical manual of international humanitarian law, accompanied by case analysis and extensive explanatory commentary by a team of distinguished and internationally renowned experts.

Non-international armed conflicts now far outnumber international ones, but the protection afforded by international law to combatants and civilian is not always clear. This book will set out the legal rules and state practice applicable to internal armed conflicts, drawing on armed conflicts from the US civil war to present day.
