Just war thinking serves a social and psychological role that international law cannot fill. Law is dispassionate and objective, while just war thinking accounts for emotions and the situatedness of individuals. While law works on us externally, making us accountable to certain people and institutions, just war thinking affects us internally, making us accountable to ourselves. Psychologically, an external focus leads to feelings of shame, while an inward focus generates feelings of guilt. Philosophers have long recognized the importance of these two moral emotions. Recently, psychologists have found that feelings of guilt are linked to positive social outcomes, such as the desire for reconciliation and reparation, while shame generates anger and hostility. Just war thinking, as an inward-looking tradition, has a special relationship with guilt. By focusing on moral emotions, just war thinking can move beyond the law in four ways, by developing an ethic of accountability, by providing a foundation for addressing moral injury, by providing a common language for discussing the costs of war, and for identifying ethical problems in radically new contexts.

The EU's politics of protecting refugees through deals such as that struck with Turkey in 2016 have been vilified by human rights campaigners. This article asks whether a full engagement with the Responsibility to Protect (RtoP) could offer the EU a way out of its current ethical and political malaise. It argues against such a proposition for two reasons. First, the EU already proclaims a long list of values that it asserts both contributed to its founding and continues to guide its actions; the addition of RtoP, which contains no obligations to protect refugees in other territories, would add little. Second, when the logic underlying the EU and RtoP's politics of protection are examined, a similarity emerges which would make such supplementation redundant. Both primarily entail a solidarity with, and a bolstering of, the sovereign capacity of the modern state. All that is offered to refugees, and other suffering populations, is a minimalist humanitarian solidarity through the “outsourcing” of protection. Neither the EU's ethos nor RtoP can therefore provide the firm ethical grounds from which to build protection for the figure most clearly failed by modern states—the refugee.

In this article I argue that the claims made about the efficacy of the Responsibility to Protect (RtoP) echo the pejorative conceptions of “utopianism” as advanced by E. H. Carr and Ken Booth in two ways: through the determination of RtoP supporters to claim “progress” in spite of countervailing empirical evidence; and through the exaggerated importance that supporters ascribe to institutionalization, which mistakenly conflates state support with a change in state behavior and interests. I argue that RtoP's impact on the behavior of states has been and will continue to be limited. Moreover, while RtoP has garnered widespread support among states, this is due to it having been rendered largely impotent through a process of norm cooptation. While both Carr and Booth criticized a particular form of utopianism, they both also defended the articulation of normative prescriptions that are not immediately feasible. To this end, I conclude by suggesting a potential reform of the existing international legal order that meets Carr's preference for normative thinking that is “utopian in the right sense.”

Despite a recent explosion of interest in the ethics of armed conflict, the traditional just war criterion that war be waged by a “legitimate authority” has received relatively little attention. Moreover, of those theorists who have addressed the criterion, many are deeply skeptical about its moral significance. This article aims to add some clarity and precision to the authority criterion and the debates surrounding it, and to suggest that this skepticism may be too quick. The first section analyzes the authority criterion and reveals that there are at least two distinct moral claims associated with it, each requiring separate evaluation. The second section outlines an increasingly influential “reductivist” approach to just war theory, explaining how this approach grounds powerful objections to the authority criterion. The third section sketches the most promising strategies for providing a qualified defense of authority, while acknowledging the further questions and complications these strategies raise. Importantly, the article aims to rehabilitate the authority criterion from within a broadly reductivist view.

Just war, international law, and world order are all historically conditioned realities that interrelate with one another in complex ways. This paper explores their historical development and current status while critically examining their interrelationship. It begins with exploring just war as a basic frame for analysis and interconnection with the other two realities. Just war is not an abstract body of moral thought but instead a practically informed morality of war rooted in Christian thought and law, Roman law, and the practice of statecraft. The essay notes the importance of the ideas of jus gentium and jus naturale in just war's fundamental formation, as well as the parallel between its three basic features—sovereign authority, just cause, and the end of peace—and the three goods or ends of politics as classically defined, namely, order, justice, and peace. The essay then moves out to explore the historical and thematic relations between just war tradition and international law, especially the law of war, arguing that these together define a moral and legal structure that is normative for world order. The final section of the paper considers the functioning of the institutions of world order in the context of challenges from rival cultural understandings of war, law, and world order and from the rise of nonstate actors in the international sphere, arguing for dialogical efforts aimed at strengthening both the moral and legal basis for world order against contemporary threats to that order.

What does authority mean under international law? There are various actors with different forms of authority, but no overarching concept of what characteristic endows an actor with authority, and even less of a coherent conception of legitimacy as a requirement for such authority. In fact, international law recognizes different authorities for different causes and different contexts, allocated to different actors, who base their authority on different characteristics (state legitimacy, representativity, military power, control). After disaggregating the concept of authority and outlining some of the consequences that follow from each type, this article highlights a number of different actors and describes the various authorities each has under international law. For instance, under jus in bello, nonstate actors can create a state of armed conflict in which they can often continue to use military means without legal sanction. While jus ad bellum may still in principle require legitimacy (in the formal sense of being a state), current jus in bello covers a range of non-state actors. Thus, from a practical point of view, the jus in bello regulations undermine any jus ad bellum requirement of legitimate authority.

Facilitating access to asylum and other forms of refugee protection for the millions displaced by mass atrocities in Syria and Iraq is essential to the implementation of the international norm of the Responsibility to Protect (RtoP). This responsibility, however, has been disproportionately shouldered by several states in the Middle East and Europe. This article explores the challenges associated with refugee responsibility-sharing in the context of RtoP and draws on work in climate justice and political realism to articulate a framework for integrating culpability as a key criterion in allocating states’ responsibilities to protect refugees. An empirical and normative assessment of U.S. responsibilities to protect refugees in the cases of conflict-induced displacement in Syria and Iraq outlines several potential paths of culpability. The article ultimately argues for greater attention to culpability, equity, and legitimacy within the discourse surrounding RtoP and refugee protection. The article also advocates linking the benefits of refugee responsibility-sharing with states’ national interests and highlights several such links with regard to U.S. responsibilities in Syria and Iraq.

The modern literature on responding to global poverty is over fifty years old and has attracted the attention of some of the most prominent analytical political theorists of the age, including Brian Barry, Charles Beitz, Simon Caney, Thomas Pogge, John Rawls, and Peter Singer. Yet in spite of this extraordinary concentration of brainpower, the problem of global poverty has quite clearly not been solved or, indeed, adequately defined. We are therefore entitled to ask two questions of any new contribution to this literature: first, what does it have to offer that past work does not; and second, what reason is there to think that, this time, it will truly make a difference. These questions will be posed below, but before undertaking this task it may be useful to offer an overview of the field, with particular attention to why the problem of global poverty seems so intractable.

In the latter half of the twentieth century, lasting memories of two world wars and astonishment over the power of nuclear weapons left both policymakers and scholars of war largely preoccupied with the possibility of a catastrophic World War III. Instead, however, the face of war since 1945 has been that of regionally limited small wars and insurgencies fought with conventional weapons. Many of these conflicts began as armed rebellions against colonial regimes, but often later evolved into armed conflicts between and among various subgroups seeking control of state government. Such conflicts have usually been asymmetrical, with the party holding the reins of state power using aircraft, artillery, and armored vehicles, while those fighting against the regime have been limited to weapons that individuals can carry, such as automatic rifles, mortars, rocket-propelled grenade launchers, and improvised weapons of various sorts. The asymmetries have also typically gone deeper, with the fighters on the former side wearing uniforms and those on the latter often not; those on the former side making use of fortified bases and those on the latter side protecting themselves by blending in with the civilian population. Further, there have frequently been asymmetries in how each side has fought, with the militarily weaker side relying on stealth tactics, deception, and attacks against nonmilitary targets of more general public value, including direct attacks on people protected as noncombatants under the laws of war. The particular range of tactics classified as terrorism begins at this point, with the specific, direct, and intentional targeting of noncombatants. Such attacks not only have been the means of choice for transnational nonstate actors, including al-Qaeda and the self-styled Islamic State, but have also been used to considerable effect in local civil wars.

By now one might hope that the robust body of theoretical work recently published on immigration ethics would have taken general political philosophy a long way from the prevailing Rawlsian-style insularity premise, according to which society is “a closed system isolated from other societies” into which persons “enter only by birth and exit only by death.” But there are still a great many political theorists whose focus is unreflectively endogenous and who assume away questions of states’ constitutive scope and boundaries. One of the signal merits of David Miller's new book, Strangers in Our Midst, is that it lucidly demonstrates why ignoring state boundary constitution is untenable for political theory. Miller shows that foundational debates in political philosophy are inescapably related, both as premise and entailment, to many normative immigration questions.

If people have a right to rebel against domestic tyranny, wrongful foreign occupation, or colonial rule, then the normative principles commonly invoked to deal with civil conflicts present a problem. While rebels in some cases might justifiably try to secure human rights by resort to violence, the three normative pillars dealing with armed force provide at best only a partial reflection of the ethics of armed revolt. This article argues that (first) the concept of “terrorism” and the ongoing attempt to define it in international law, (second) the laws of war and their application to armed conflict, and (third) the Responsibility to Protect all obscure as much as clarify the problem. Given the prevalence of political oppression and the occurrence of civil conflicts originating in attempts to confront it, there is therefore a pressing need to establish a place for the rights of rebellion in the international normative architecture.

Why do we need dialogue between ethical and legal perspectives on norms governing the initiation and conduct of interstate conflict? This essay will examine this question by first critiquing the 2013 Tallinn Manual on the International Law Applicable to Cyber Warfare, which sought to apply existing legal frameworks that govern international violence to a new form of conflict. While the manual is for the most part ethically commendable, the first half of the essay will highlight several of its ethical shortcomings and will then extract general reasons why international law nevertheless must be informed by ethical analysis. The second part of the essay will affirm the importance of law for ethical analyses of justified responses to the burgeoning phenomenon of sublethal harms. While states have always used sublethal harms to weaken adversaries, technological developments have magnified the regularity and effectiveness of these practices, particularly against free societies. Responses to such attacks may include—in addition to defensive countermeasures—punishments that deter and reform, and may target “indirect participants” such as financial supporters. However, determining which responses are ethically justified will require insights gleaned from criminal and tort law.

The world is going through a crisis of the international liberal order, exemplified by a host of recent shocks: the invasion and annexation of Crimea by Russia; the transnational dimensions of conflicts such as in Syria; the United Kingdom's decision to exit the European Union; the attempted coup d’état in Turkey and its reversal toward autocracy; and the election and rise of non-universalist and illiberal governments as well as politicians who operate under the populist rubric in countries that are viewed as beacons of democracy and stability. These shocks have catalyzed two outcomes. First, the prevailing global norms that serve as the custodians of peace and security have been the subject of revived debate. Second, and relatedly, these shocks have prompted deep reflection on the role of institutions such as the European Union and the North Atlantic Treaty Organization (NATO), as well as the roles of the supposedly democratic members within those institutions.

In the rapidly expanding literature on the ethics of climate engineering, a lot has been made of the fact that stratospheric aerosol injection would for the first time create a world whose climate had been intentionally shaped by deliberate human decisions. Intention has always mattered in ethics. Due to the importance of intention in assigning culpability for harms, one might expect that the moral responsibility for any harms created during an attempt to reconstruct the global climate using stratospheric aerosols would be considerable. This article investigates such an expectation by making a comparison between the culpability for any unintended harms resulting from stratospheric aerosol injection and culpability for the unintended harms already taking place due to carbon emissions. To make this comparison, both types of unintended harms are viewed through the lens of the doctrine of double effect. The conclusion reached goes against what many might expect. The article closes by suggesting that a good way to read this surprising conclusion is that it points toward the continuing moral importance of prioritizing emission reductions.

In his article “Carbon Emissions, Stratospheric Aerosol Injection, and Unintended Harms,” Christopher J. Preston compares the culpability of carbon emitters versus that of geoengineers deploying stratospheric aerosol injection (SAI). This comparison relies on a parallel between carbon emitters and SAI deployers that requires both to be agents. However, both are not. While the harms of geoengineering will be caused by culpable agents acting intentionally, the harms connected to climate change emerge out of the uncoordinated actions of billions of people. Taken as a large group, carbon emitters cause harm but do not constitute an agent. Taken individually, carbon emitters are agents but do not cause the harms of climate change. As a result, the parallel collapses, and Preston's “surprising” conclusion is one that he is not entitled to reach.
