Jus ad bellum

Episode 21 – Yasuyuki Yoshida on Japanese Perspectives on the Jus ad Bellum Regime

by

In this episode I speak with Yasuyuki Yoshida, Professor of International Law at Takaoka University in Toyama Japan, and former Captain(N) in the Japanese Maritime Self-Defence Force. We discuss Japan’s posture on various aspects of the jus ad bellum regime, and whether or how its position may have changed as a result of the “reinterpretation” of Article 9 of the Constitution of Japan. Article 9 famously renounces the threat or use of force, and has long been understood to prohibit any collective self-defense or use of force authorized by the UN Security Council, but in 2014 the government purported to “reinterpret” the provision to relax its constraints. We discuss how the new policy relates to the jus ad bellum, and what Japan’s position is on a number of the more controversial elements of the doctrine of self-defense. The discussion includes surprising insights on how Japan would view a Chinese incursion on the Senkaku Islands, whether Japan would help defend Taiwan, and whether the US could invoke collective self-defense of Japan for preemptive strikes on North Korea. Another fascinating conversation!

Episode 20 – Rebecca Ingber on Legally Sliding into War

by

In this episode I speak with Rebecca Ingber, Professor of Law at Yeshiva University’s Cardozo School of Law, and formerly a lawyer in the Office of Legal Advisor in the U.S. Department of State. We discuss a recent essay in which Rebecca examines how international and domestic law operate together to facilitate the incremental moves by which the U.S. initiates, expands, and extends armed conflicts. The process involves legal justifications and rationales for each step towards war, with legal interpretations that, while made in good faith, are often strained and even beyond the pale. What is more, Congress and the courts tend to look to the international law principles as limitations on executive branch conduct, but then there is little check on how the executive branch lawyers interpret and expands such principles — and all of this focus on legal justification displaces a necessary and deeper policy analysis of the reasons for engaging in armed conflict. In exploring these issues, we also talk about whether legal scholars are fulfilling their role of keeping the government honest in its interpretation of international law, where exactly within the government such decisions get made, and why and how different areas of law get conflated and confused in the justifications for war!

Episode 17 – Nessa Interviews Martin on Climate Change and the Jus ad Bellum Regime

by

In this episode, I relinquish the hosting to  Jasmin Johrun Nessa of Liverpool University Law School, and she interviews me on my recent work on how the climate change crisis may implicate the jus ad bellum regime. Jasmin is finishing up her doctorate on the doctrine of self-defense in jus ad bellum, and teaching international law among other things, at Liverpool Law School. She is also a co-general editor of the Journal on the Use of Force and International Law’s “Digest of State Practice.” We discuss my recent article on the climate change crisis and the jus ad bellum regime, in which I argue that as the climate change crisis deepens, and not only the consequences but the causes of climate change are viewed as threats to both national security and international peace and security, there will be pressure to relax the jus ad bellum regime to allow for the threat or use of force against “climate rogue states.” This will include a relaxation of the conditions for permissible self-defense, as we have seen in response to other novel threats, and pressure for a new exception to the prohibition on the use of force, along the lines of humanitarian intervention. I suggest that these arguments will be persuasive but dangerous, not only increasing the likelihood and incidence of war, but also being counterproductive to the climate change crisis effort itself — and so we must begin to discuss the issues now, and contemplate how to resist such developments, before the pressure mounts.

Episode 16 – Terry Gill on the Use of Force Against Non-State Actors

by

In this episode, I speak with Terry Gill, the Professor of Military Law at the University of Amsterdam, Center for International Law, and the Netherlands Defence Academy, and also the Director of the Netherlands Research Forum on the Law of Armed Conflict and Military Operations (LACMO). We discuss his recent article (co-authored with Kinga Tibori-Szabó) on the use of force against non-state actors (NSAs) within the territory of states that that are not substantially involved with, or exercising significant control over, the NSA, but which also do not consent to the use of force against the NSA within their territory – a familiar but still hot subject of ongoing debate. Terry explains why a strict understanding of the principle of necessity should be at the center of the analysis of these issues, and thus offers some perspectives on the so-called unwilling or unable doctrine that are quite different from others who support the right to use force against NSAs. We also revisit his much earlier work on the Nicaragua v. USA judgment of the ICJ, and how its formulation of attribution should be understood in this context.

Season 2: Episode 15 – Michael Schmitt on Cyber Ops and the Laws of War

by

In this episode, the first of “Season 2”, I speak with Michael Schmitt, who is, among other things, Professor of International Law at the University of Reading, Francis Lieber Distinguished Scholar at the United States Military Academy at West Point, and Charles H. Stockton Distinguished Scholar at the US Naval War College.  He is also the Director of the International Group of Experts responsible for the Tallinn Manual 2.0 On the International Law Applicable to Cyber Operations. We discuss the development of the Tallinn Manual, the reasons for a 3.0 that is currently underway, and the implications and significance of recent state declarations and statements on their understanding of how the jus ad bellum and IHL regimes apply to cyber operations. We also grapple with some of the difficult issues that arise in trying to apply these legal regimes to cyber ops, and, more importantly, how efforts to do so may threaten the integrity of the legal regimes themselves. Both a wonderful introduction for the uninitiated to how the laws of war apply to cyber ops, and a fascinating discussion of some of the more knotty questions for the experts.

Episode 14 – Federica Paddeu on Consent as a Justification for the Use of Force

by

In this episode I speak with with Federica Paddeu, Professor and Derek Bowett Fellow in Law at Queen’s College, Faculty of Law, Cambridge University in England. We discuss her recent work on how best to understand the operation of consent as a justification for the use of force in international law—is it part of, or intrinsic to, the definition of the prohibition on the use of force in Article 2(4) of the Charter? Or is it extrinsic, a separate and independent exception or justification for the use of force? Consider how consent operates quite differently in the crimes of rape (intrinsic to the definition) and battery (extrinsic defense). Our discussion makes clear that the answer to the question of how consent operates has important implications for how we think about and understand the nature of the use of force itself, on whether the prohibition in its entirety can be a jus cogens norm, as well as for how the justification ought to operate in practice. We end by also discussing her earlier work on self-defence as a circumstance precluding wrongfulness (work that will change how you understand that too), and how her thinking about exceptions and justifications in the jus ad bellum has evolved over the course of her intellectual journey. A fantastic conversation!

Episode 12 – Tom Ruys on the Exercise of Self-Defense to Recover Occupied Territory

by

In this episode, I speak with Tom Ruys, Professor at the Faculty of Law, Ghent University, Belgium. We discuss a debate he recently sparked with a blog post on the question of whether states my invoke the right of self-defense to justify the use of force to recover previously occupied territory, looking specifically through the lens of the recent seizure of territory in Nagorno-Karabakh by Azerbaijan in a short sharp armed conflict with Armenia. Tom and his co-author, Filipe Rodriguez Silvestre, argue that the initial occupation (in the 1988-94 conflict in the case of Nagorno-Karabakh) cannot be characterized as a continuing armed attack, and that self-defense cannot justify the use of force to recover the territory. In a responding blog post, Dapo Akande and Antonios Tzanakopoulos of Oxford argue that such a use of force can indeed be an act of self-defense, and that Azerbaijan’s actions are in fact so justified — and so we explore the competing arguments. To start things off, however, we do discuss Tom’s seminal book, ‘Armed Attack’ and Article 51 of the UN Charter, both to lay the foundation for discussing self-defense in Nagorno-Karabakh, and to explore whether any of his positions have evolved since publication of the book ten years ago. Finally, we discuss briefly his recent work on economic sanctions, and the relationship between sanctions and the collective security regime. Not to be missed!

Episode 10 – Eliav Lieblich on the Humanization of Jus ad Bellum

by

In this episode, I speak with Eliav Lieblich, Professor of Law at The Buchmann Faculty of Law, Tel Aviv University, Israel, about the relatively under-studied relationship between international human rights law and the use of force by states. Eliav, in a forthcoming article, uses a recent General Comment of the U.N. Human Rights Committee as a point of departure for analyzing whether, and to what extent, violations of the jus ad bellum regime might also violate the right to life enshrined in the International Covenant on Civil and Political Rights. Thus, does an act of aggression by a state infringe human rights law as well as violate the jus ad bellum regime? And do governments contemplating the use of force in self-defense have to consider the human rights obligations owed to its own citizens, and the rights of the people in the state against which it is intending to use force? Eliav explores these fascinating questions, and their important implications, from not only a doctrinal and theoretical perspective, but also through the lens of just war theory and ethics as well.

Episode 9 – Oona Hathaway on War Powers and the Scope of National Security

by

In this episode, I speak with Oona Hathaway, Professor of Law at Yale Law School and Professor of International Law and Area Studies at the Yale University MacMillan Center. We discuss the constitutional and legislative constraints on the executive war-making power, both in terms of the theoretical rationale for such constraints, and in terms of the constitutional and legislative form such constraints take in U.S. legal system. After discussing how and why such constraints in the U.S. have eroded over time, reaching a nadir in the Libyan intervention, Oona explains how the War Powers Resolution could be revised, in ways more consistent with international law, and how Congress could employ the courts, in order to re-establish Congressional authority over decisions to engage in armed conflict. We also discuss how such crises as the Coronavirus pandemic and climate change should cause us to re-think the scope and character of national security priorities and policy. We wrap up with a short discussion of the collaborative process involved in the writing of her co-authored work The Internationalists, and the ethical obligations in being a government lawyer. A fantastic foray into war powers and evolving perspectives on national security!

Episode 7 – Alonso Gurmendi Dunkelberg on Latin American Approaches to the Laws of War

by

In this episode, I speak with Alonso Gurmendi Dunkelberg, Professor of Law at the Universidad del Pacifico in Lima, Peru. We discuss his recent writing on the Latin American approaches to, and perspectives on, the jus ad bellum regime and principles of non-intervention. Drawing on a rich history of the Latin American response to the Monroe Doctrine and European approaches to intervention in the 19th Century, Alonso explains how the distinct Latin American perspectives developed, found expression in the Montevideo Convention of 1933, and contributed to the Latin American embrace of the U.N. system in 1946. He explains how a misunderstanding of the Latin American perspective leads to common misinterpretations of Latin American positions and responses to recent interventions, such as those in Syria, and debates over doctrinal issues, such as the validity of humanitarian intervention or the unwilling or unable doctrine. We round off our discussion by putting it all into the context of Third World approaches to international law. An eye-opening romp through history and theory!
