Episode 43 – Janina Dill and Monica Hakimi on The Attacks on Iran: Implications for International Law

by

In this episode I speak with Monica Hakimi of Columbia Law School and Janina Dill of the University of Oxford about the legal implications of the unlawful US and Israeli war attacks on Iran. We begin by establishing the unlawfulness under jus ad bellum before turning to the larger and more unsettling questions raised by this moment: whether the UN Charter system on the use of force is dying or already dead, and what distinguishes this crisis from prior violations. Janina argues that the preventative self-defense being advanced by the US, if normalized, would be fundamentally incompatible with the rule of law, drawing on the German concept of Rechtsstaatlichkeit to show why a system in which states use force based on unilateral threat assessments is not a legal order but a regime of self-help. Monica situates the crisis within longer structural trends — the slow transfer of decision-making authority away from the Security Council and toward individual states acting unilaterally, the erosion of US commitment to the system that long predates the Trump administration, and the failure of states collectively to rally behind the Charter when it mattered. From there, we explore what states, as well as international lawyers and legal scholars should be doing in a moment when unlawfulness has given way to open lawlessness and complete disregard for the law. A rich and urgently important conversation.

Episode 42 – Monica Hakimi on Understanding the Current Crisis in International Law

by

In this episode I speak once again with Monica Hakimi of Columbia Law School about how best to understand and respond to the current upheaval in the international legal order. We explore some of Monica’s recent theoretical work on how to better understand the operation of international law as a necessary foundation for  understanding both why and how the international legal order is in a process of such dramatic transformation, in large measure due to the withdrawal of American support, and thus how best to recognize the opportunities that may allow us to better respond to the crisis. From this theoretical foundation we move into a discussion of practical ways international lawyers, scholars, and jurists might best respond to specific aspects of the crisis, including the weakening of both the jus ad bellum and IHL regimes. A fascinating and necessary conversation – particularly in light of the intervention in Venezuela that occurred a week after we recorded this!

Episode 41 – Brian Finucane on the US Killing of Drug Smugglers

by

In this episode I speak with Brian Finucane, a senior advisor at the International Crisis Group, and former lawyer in the Office of the Legal Advisor at the U.S. Department of State, where he advised on law and policy issues relating to war powers, the use of force, counterterrorism and the laws of war. We discuss the legality of the U.S. military strikes against alleged drug smugglers in the Southern Caribbean and Eastern Pacific, exploring whether either self-defense under jus ad bellum, or international humanitarian law applicable to armed conflict, can be said to apply to these strikes; and, if not, whether there is any possible justification or defense for these killings under either international human rights law or domestic U.S. criminal law. We also discuss lawfulness of any future U.S. military strikes against alleged drug cartels within the territory of Venezuela, and the separate question of the lawfulness of any larger military intervention in Venezuela for purposes of regime change. We try to put the strikes and threat of wider military action in the region into the broader context of the ongoing assault against the international rule of law – this activity is important precisely because it is so brazenly violating the most fundamental international law rules.

Episode 40 – Harold Hongju Koh on the National Security Constitution for the 21st Century, International Law, and the Trump Administration

by

In this episode I speak with Harold Hongju Koh of Yale Law School, former legal counsel to the Department of State among several other positions in government, as well as former Dean of Yale Law School. We discuss his new book, The National Security Constitution for the 21st Century, which builds on his famous earlier book that will be familiar to most listeners. The new book similarly examines the structural and systemic reasons for the dangerously increased strength of the executive branch of government in the U.S., but analyzes how the process has simply accelerated in the post Cold-War and post 9/11 eras, and it explores the implications for American use of force, foreign relations, and international law. We discuss not only the evolution and implications of these systemic failures, but also his recommendations for reform, and the role of lawyers and legal scholars in responding to the problem.  We even revisit his own role in government in the context of these issues, and discuss whether he has a different perspective on any of the positions he once took. Finally, we discuss how a second Trump administration makes the prospect for reform more difficult, and the outlook for international law more fraught – but ultimately we end on an optimistic and even inspiring note, as Harold explains how and why lawyers and legal scholars must answer the call to defend the rule of law.

Episode 39 – Dill & Haque on IHL and the IDF Conduct of Hostilities in Gaza

by

In this episode Janina Dill of the University of Oxford and Adil Haque of Rutgers Law School return to the podcast to address the question of whether it is possible now, while hostilities are still ongoing, to assess whether some aspects of the IDF’s conduct of hostilities may be in violation of IHL. The question is germane because many argue that one cannot assess such violations until all of the evidence is available and has been analyzed, and we discuss why this may not be so. And the focus on the IDF, without delving into the violations of Hamas and Islamic Jihad, is justified because there is really no debate over the violations and war crimes committed by either of these – but there remains quite robust debate over whether the IDF is acting in compliance with IHL, and the issue is highly relevant now for countries that are supplying Israel with weapons. In the discussion we begin with explanations of the core principles of IHL, namely distinction, proportionality, and precautions in attack, as well as the treaty provisions that codify them, and how these are subject to interpretation. We also explore how the concept of intent, as well as the standards of evidence, should be understood differently depending on whether one is assessing collective violations of IHL or trying to prosecute individuals for war crimes, and whether one is considering the operation of law as an ex ante modifier of behavior, or as ex post mechanism for imposing accountability. We then dive into a discussion of some of the specific aspects of IDF conduct of hostilities, with a focus on strikes on civilian targets, and the use of indiscriminate weapons (or use of inappropriate weapons causing indiscriminate harm) in civilian areas, as well as how one should best understand the IDF’s use of warnings, the use of AI in targeting decisions, and the claims that Hamas is employing human shields. There is much to unpack, and there is much that we could not get to, but it is fascinating if sobering analysis.

Episode 38 – Brunk and Hakimi on the Prohibition Against Annexations

by

A discussion with Ingrid Weurth Brunk of Vanderbilt University Law School and Monica Hakimi of Columbia University Law School, on their recent law review article on the prohibition against annexation. They are argue that the prohibition against the annexation of territory is related to and has emerged from three other fundamental principles of international law – namely the prohibition against the use of force, the right to self-determination, and the principle of territorial sovereignty – but that it is nonetheless distinct from each of these, and that this distinction is important. The significance of the principle has been obscured and it is too often conflated with the prohibition on the use of force, in ways that have important theoretical and practical implications for the jus ad bellum. We discuss all of this, and the ways in which they argue that the principle is under threat, and possibly in the process of being eroded, with significant implications for not only jus ad bellum but international law and the inter-state system itself. A fascinating discussion about a really important piece of scholarship.

Episode 37 – Martin and Hafetz on “Eye in the Sky”

by

This episode is a joint production and cross-posting with the Law on Film Podcast, produced and hosted by Jonathan Hafetz, a professor of law at Seton Hall Law School, and expert in national security law, international criminal law and human rights, as well as constitutional law. We discuss the film “Eye in the Sky,” a 2015 film likely known to most JIB/JAB listeners,  about a joint British and American drone strike against al-Shabaab terrorists in Kenya, and which intelligently and engagingly explores the legal, ethical, philosophical, political, and strategic issues raised by the operation. We not only examine the film’s treatment of the legal issues implicated, including whether IHL should apply at all, and how the principles of distinction, necessity, proportionality, and precautions in attack are illustrated in the film, but we also explore the relationship between these principles and some of the ethical and strategic aspects of the decision-making in the film. We round out the conversation with a discussion of some other engaging films that similarly explore law in the context of armed conflict. I very much enjoyed the conversation!

Episode 36 – Hakimi, Haque, and Milanovic on the Right of Self-Defense in Gaza

by

In this episode I speak with Monica Hakimi of Columbia Law School, Adil Haque of Rutgers Law School, and Marko Milanovic of University Reading School of Law, on the question of whether Israel has a right of self-defense under Article 51 of the U.N. Charter in response to the Hamas attacks of October 7. This question has been the subject of some confusion in both the political and legal discourse, and raises a host of complicated issues regarding the scope of the prohibition on the use of force under Article 2(4) of the U.N. Charter and its relationship with the right of self-defense under Article 51, whether the right of self-defense depends upon Gaza being part of an established state of Palestine, whether self-defense is available in response to attacks by non-state actors in any event, whether the prohibition on the use of force may extent to protect non-state entities with a right of self-determination, what the scope of legitimate resistance by such entities may be, and how best to interpret the scope and operation of the principle of proportionality under the doctrine of self-defense if it applies here. We explore all of these questions, and discuss how the positions and actions taken by states may have in relation to these issues may have significant implications for the development of the jus ad bellum regime. An important and fascinating discussion.

Episode 35 – Tom Dannenbaum on Sieges, the War Crime of Starvation, and Gaza

by

In this episode Tom Dannenbaum, a professor of international law and Co-Director of the International Law and Governance Center at The Fletcher School of Law & Diplomacy at Tufts University, discusses his work on the war crime of intentional starvation of civilians as a method of warfare. We begin with an analysis of the proper interpretation and operation of the prohibition on starvation as a method of warfare in International Humanitarian Law, as provided for in the Additional Protocols to the Geneva Conventions and customary international law, and how this prohibition applies in the context of an encirclement siege, and how it relates to military necessity and the principle of distinction. We then turn to his contribution to the discourse on the best interpretation of the criminal prohibition in the Rome Statute. This involves a discussion of how best to understand the term “method of warfare,” what precisely constitutes the actus res of the crime, what is the nature of the intent that is required, and what the underlying wrong is said to be – and Tom’s claim that the incremental and drawn-out process of starvation and deprivation, far from being a mitigating factor, is precisely what makes the crime distinct, and informs how we should think about the actions that are prohibited. Finally, we turn to discuss the issue of the current siege of Gaza, informed by this theoretical analysis of how the relevant IHL and ICL prohibitions operate.

Episode 34 – Chris O’Meara on Necessity and Proportionality

by

In this episode I speak Chris O’Meara, Lecturer at Exeter University Law School, about his new book, Necessity and Proportionality and the Right of Self-Defence in International Law. Chris describes his novel taxonomy for dividing the principle of necessity between general and specific necessity, and his blending the quantitative and teleological approaches to the principle of proportionality, and goes on to explain how the relationship among necessity, proportionality, and imminence should be properly understood. We delve into some of the more potentially controversial claims he makes, such as: on how he thinks necessity operates as a limiting principle; why the gravity threshold for armed attack should be lowered; whether the principles of self-defence are modified in responses to non-state actors; why the assertions and actions of a minority of powerful states, particularly in relation to clearly unlawful uses of force, and the corresponding silence of other states, should be considered so heavily in thinking about custom – and so much more! A fascinating conversation.
