The contributions to this Special Issue examine multispecies perspectives on the political dynamics of international life. Building on this theme, I consider the complex and manifold ways in which the subject of security can be understood in terms of more-than-human personhood. First, by thinking of more-than-human animals as phenomenally conscious persons, we might better appreciate the multispecies complexity of security as an agentic and affective experience. Second, attending to the spiritual character of certain indigenous articulations of personhood presses us to decipher how spiritual claims might inform moral and legal dimensions of multispecies security-seeking behaviour. To illustrate the significance of these moves, I first draw on more-than-human experiences of war, pathogenic viruses, and the global factory farm. I then explore conceptions of spiritual personhood in the context of Ojibwe responsibilities to protect wolves. These perspectives on personhood demonstrate possibilities for cultivating greater interest in the multispecies experience of security.

Seeing as colonialism is ubiquitous to where International Relations (IR) comes from, what it explains and who it represents, many have argued that the decolonisation of the discipline is impossible. However, in this agenda-setting introduction, I place decolonisation squarely in the realm of possibility and ask, ‘what would a decolonised field look like?’. In answering this question, the contributions in this forum take point of departure from varied sites within the discipline, as they seek to materialise real change that reimagines what IR is and does as a discipline that was established as a scholarly defence for colonialism. Herein they propose decolonisation as a structure that upends the discipline’s colonial epistemological roots, rethinks core concepts and underlines the need to forefront geographies, peoples, and perspectives that were underrepresented in a colonial discipline. Equally, they recognise that decolonisation is a messy affair, that takes a non-linear trajectory. However, seeing as colonialism did not just inflict material impoverishment but also sought to alienate the colonised from their sense of self, this messiness is only expected. So, rather than be discouraged by this, this forum views the non-linear trajectory to be an unavoidable facet of any attempt at decolonising the discipline.

This article explores ways of decolonising Development Studies by: (1) examining the discipline’s tendencies towards what some have called ‘imperial amnesia’, that is, proclivities towards disavowing if not erasing European colonialism, most evident in 1950s–1960s Modernisation theory, but also more recently in the work of such analysts as Bruce Gilley and Nigel Biggar; (2) considering the opportunities and perils of ‘epistemic decolonisation’, that is, ways of decolonising knowledge production in the discipline, including the limits of ‘non-Eurocentric’ pedagogies; and (3) reflecting on forms of material decolonisation (e.g., the reduction of socioeconomic inequalities by improving better access to education or resisting the corporatisation of publicly funded research) that need to accompany any epistemic decolonisation for the latter to be meaningful.

This is a piece of creative non-fiction. The letter from a daughter to a father is an attempt to understand intergenerationally shared histories, experiences, and different orientations. It aims to imagine what decolonial thinking could look and feel like. Interdisciplinary in its orientation, the letter moves between personal stories and the broader scholarly quest to contemplate the embodied racialized violence of the current conjuncture. The letter suggests that embodied racialized violence is powerful and banal. It explores how it can be carried in the ties that bind – the love, minds, bodies, experiences, and stories of – a familial relationship and the people they encounter. It also represents an inversion of scholarly work in which the interactions that hone arguments are thinly noted in brief acknowledgements, and the citationary writing takes centre stage. Here, the interaction is central, and the citationary writing is laid out in footnotes.

Cosmopolitanism claims to be the most just and inclusive of mainstream approaches to the ethics and practice of world order, given its commitment to human interconnection, peace, equality, diversity, and rights, and its concern with the many globalised pathologies that entrench injustice and vulnerability across borders. Yet it has largely remained oblivious to the agency, power, and value of non-human life on a turbulent and active Earth. Without rejecting its commitments to justice for human beings, the article challenges its humanism as both morally and politically inadequate to the situation of the Anthropocene, exemplified by the simultaneous crises of climate change, mass extinction, and the COVID-19 pandemic. In answer, the article develops new grounds and principles for an interspecies cosmopolitanism, exploring how we can reimagine its ontological foundations by creating new grounding images of subjectivity, existential unity, institutional organisation, and ordering purpose. These, in turn, can support political and institutional projects to secure the rights of ecosystems and people to flourish and persist through an increasingly chaotic epoch of human dominance and multispecies vulnerability across the Anthropocene Earth.

The term disruption has been offered as both an ethos and set of practices framed as a broad response to all manner of social and political ills. This article offers a speculative reflection on disruption as a planetary mood, and the sensory qualities of a change in politics no longer defined by governance and what is governable, but by a series of continuous experiments hedged upon the creation of new geopolitical frontiers and life forms that position all matter and contingency towards a specific kind of value tied to chaos. In thinking about the kinds of authority and legitimacy being fashioned around visions of so-called disruptive futures, I draw on materially-grounded illustrations of disruptive dispositions to examine three different arrangements of affect, feeling, and intensity being animated to give disruption its power of transmissibility and adaptability, as well as its unintuitive emphasis on disorder and ‘breaking things’ as both a moral good and unconditional response to questions concerning global conflict, crises, and instability. Ultimately, disruption as a planetary mood draws on a libidinal economy that does not bend towards justice or equity, thus warning against misanthropic commitments to collapse and the consequences of investing in a world premised on an ethos of erasure.

What, this essay asks, is the relation between contemporary IR scholarship and the existentialist intellectual and cultural tradition? How is our discipline informed and animated by existentialist thinking? Is existentialism a heritage to be recovered, claimed, and embraced by IR scholars, or a shadow to be escaped? And what resources does it furnish us for thinking through the kind of issues that IR scholars are called upon to grapple with today? These questions are not purely theoretical. There are practical and political reasons, not only for considering them, but for considering them now. Living through what has been termed an unfolding ‘Age of Anxiety’, we find ourselves confronted by existential questions and existentialist ideas at almost every turn. It is, however, unclear how substantive or meaningful this apparently existentialist moment truly is. Does existentialism have something to say to contemporary IR, or does it flatter to deceive? We think the time is ripe to take stock of existentialism as it relates to IR and global politics. This is the purpose of this article and of the collection of essays it introduces.

IR proceeds on a Eurocentric ontological assumption that sovereignty has universal validity today. How can IR be decolonised, when in spite of countless examples of the enactment of ‘sovereignty otherwise’, the discipline remains unconcerned with the fact that the logic of sovereignty remains uni-versal. The question is as much political as it is intellectual, because as a discipline, we have allowed the inertia of our professional rhythms to marginalise pluri-versal sovereignty, or the organisation of sovereignty along different ontological starting points. I argue IR must abandon its disciplinary love affair with uni-versal sovereignty. The tendency to ‘bring in’ new perspectives by inserting them into an already ontologically constituted set of assumptions works to protect IR’s Eurocentricity, which makes disciplinary decolonisation untenable. I propose that as a starting point, IR needs to be more mature about recognising the decolonisations that are happening under our very feet if we are to stand a chance at disciplinary level decolonisation. As an illustrative example, I explore an ongoing collision of settler-colonial and Mi’kmaw sovereignty through the issue of lobster fisheries in Mi’kma’ki, or Nova Scotia as the territory is known to Canadians.

The Nuclear Age is said to be defined by the notion of existential threat. The ability to destroy human societies in their entirety with a single class of weaponry raises profound questions about human existence. It even gives us a new form of species extinction – ‘thermonuclear omnicide’. Unsurprisingly, existentialism was a philosophy that found its feet in the shadow of the bomb. This article explores the possibilities and limits of an existentialist approach to nuclear dangers. It contrasts the views of two figures central to early existentialism: Jean-Paul Sartre and Raymond Aron. Sartre responded to the existential threat of nuclear war with moral outrage about the ‘unreality’ of the Cold War politics driving the arms race and an existentialist call to reject militaristic social norms. Aron, a key figure in early IR realism, famously rejected existentialism and turned instead to outlining norms for an international society that might better restrain nuclear-armed decision-makers. Bringing Sartre’s and Aron’s post-Second World War discussions into the new century, this article argues that the ongoing, and even growing, threats posed by nuclear weapons highlight the limits of Sartre’s approach as a guide to authentic existence in modern life. Instead, it supports Aron’s more conservative approach but also draws on Existentialism to extend it, strengthening the nuclear taboo for the sake of human survival as a persistent but urgent political project. At a moment in IR when scholars and other analysts are once again critiquing the fragile norms of global order and speculating about the dawn of a ‘Third Nuclear Age’, theoretical reflection on the politics of existential threats and the hard choices they entail remain indispensable aspects of IR’s theoretical toolkit. While Sartre and other existentialists argued convincingly that existence precedes essence, Aron reminds us that survival remains a precondition for both.

A significant set of epistemic and political transformations are taking place as states and societies begin to understand themselves and their problems through the paradigm of deep neural network algorithms. A machine learning political order does not merely change the political technologies of governance, but is itself a reordering of politics, of what the political can be. When algorithmic systems reduce the pluridimensionality of politics to the output of a model, they simultaneously foreclose the potential for other political claims to be made and alternative political projects to be built. More than this foreclosure, a machine learning political order actively profits and learns from the fracturing of communities and the destabilising of democratic rights. The transformation from rules-based algorithms to deep learning models has paralleled the undoing of rules-based social and international orders – from the use of machine learning in the campaigns of the UK EU referendum, to the trialling of algorithmic immigration and welfare systems, and the use of deep learning in the COVID-19 pandemic – with political problems becoming reconfigured as machine learning problems. Machine learning political orders decouple their attributes, features and clusters from underlying social values, no longer tethered to notions of good governance or a good society, but searching instead for the optimal function of abstract representations of data.

This essay revisits the question of mass destruction through the perspectives offered by postcolonial thinkers.

Forest ecosystems are crucial to survival on Earth. This article argues that trees and forests are both vital components of a healthy Earth system and productive examples for expanding International Relations’ disciplinary boundaries. The article discusses the forest in three contexts: the global, the (post)colonial, and from the tree itself. From tree planting as a practice of social and environmental justice, to postcolonial and Indigenous science and knowledge, to the mycorrhizal ‘wood wide web’, a focus on trees, forests, and biosphere opens the possibility for a multispecies IR. Through a consideration of trees and forests in law, treaty, culture, and science at the local and global level, this article adds to a growing literature in IR that strives to bring the non-human, more-than-human, or other-than-human creatively and productively into the discipline. Foregrounding the forest's materiality and trees’ symbolic power for human cultures opens important pathways to understanding how the non-human is, and should, alter and affect global politics.

The term disruption has become a buzzword for our times, although there is little clarity over what the term means, how it is deployed, and towards what ends. In order to understand the analytical and political stakes that are embedded in the deployment of ‘disruption’ as a rationale for various sources of upheaval, in this article I argue that these three terrains of disruption should be understood as theories of governance, and term them ‘disruption from above’, ‘disruption from the middle’, and ‘disruption from below’. Each terrain of disruption embodies different ethoses, actors, and goals: the first connoting elite-driven creative destruction and innovation; the second obfuscating the capitalist imperative that produces world-systemic upheavals; and the third seeking to expose the structures of violence and inequality built into such practices. I illustrate these three terrains through a structural account that traces the popularity of the disruption discourse from its origins to its material application; analyse an illustrative example of the assetisation of infrastructure and how it bureaucratises governance and shifts relations of power; and conclude by examining infrastructural forms of protest against such forms. I argue that the confusion over what disruption means, who exercises it, and upon whom is not a coincidence: rather, disruption's polysemy is structurally produced as a way to disguise ongoing capitalist crisis as a technical problem that market innovations can solve.

IR scholars increasingly turn to the writings of Existentialists to make sense of the multiple and entangled planetary crises that characterise the twenty-first century. In this article, I argue that two postwar intellectuals, Günther Anders (1902–1992) and J. G. Ballard (1930–2009), offer a rich intellectual ancestry and inspiration to such scholarship. Both authors critically and creatively reworked central Existentialist ideas in the context of postwar technological acceleration and the development of nuclear weapons. To Anders and Ballard, nuclear weapons symbolised, and were the most extreme manifestation of, the pathologies they associated with technological modernity: mass consumption, spectacular violence, a deadening of affect, and an increased inability of humans to psychologically process and grasp the destructive capacities of science and technology. To counter these trends, they both firmly relied on Surrealism to bolster the human imagination as a catalysator for personal and social transformation. I argue that their work offers an opportunity to reconnect the study of nuclear weapons in IR to broader existentialist questions and suggest that their respective attempts to foreground human being in the nuclear age as ‘being-towards-extinction’ holds important lessons for recent attempts to recentre the study of IR around planetary imaginaries of extinction.

Teaching and studying International Relations (IR) in the Caribbean makes the region’s invisibility unmissable. Nevertheless, these locales have significantly influenced the structure of global processes and are also acutely affected by global occurrences. Exposure to the global has led Caribbean scholarship to offer worthwhile insights into world affairs. Thinkers from the region and its diaspora provide noteworthy perspectives about the criticality of the Caribbean in building systems of empire and a world structured around race, class, and gender in ways that mainstream IR approaches may miss. This article takes its starting point as the Caribbean intellectual tradition. Grounding IR scholarship in this neglected, though highly pertinent, thought tradition is one angle from which to decolonise the discipline. The article connects these insights to an appraisal of a nimble strategy that Caribbean states and territories employ to navigate the global. The strategy of developing offshore financial centres (OFCs) can educate us about the functioning of the world if we are willing to think about it as embedded in global processes rather than as a problematic gimmick. In sum, this piece illustrates how using Caribbean thought and examining Caribbean global integration strategies can help to decolonise IR.

Rats tend to thrive wherever humans do. In recent centuries, the growth of human populations around the planet has meant the growth of a nearly equivalent global population of rats, particularly in cities, where they thrive on trash, food scraps, and infrastructure, and widely stymie human efforts to get rid of them. This forced coexistence has inspired a wide range of human responses, ranging from revulsion and extermination efforts as vermin, to religious veneration and use as experimental lab animals. At the same time, the political figure of the rat has played a constitutive role in violence and experimentation against human populations who are deemed as rat-like. To understand these linked dynamics, the article frames the idea of interspecies internationality, against both Anthropocene and geopolitical readings of the planetary condition. It then elaborates three axes around which rat assemblages have been formed – exterminative, experimental, and ecological. The article concludes by arguing that the rat, as interspecies figure of politics and as living creature, allows us to understand important dynamics around the generation of disposable life, political difference, and conditions of coexistence, in ways that are critical to the entwined politics of life on the planet.

This paper examines the influence of nuclear weapons on fantasies of racial violence. Specifically, it argues that weapons impact the emergence of social formations, producing unique patterns of thought, desire, anticipation, and identity. While the effects of nuclear power have been central to disciplinary debates in international studies, existing critical commentary has largely focused on the discriminatory nature of the global nuclear hierarchy. By focusing on the productive impact of weapons on cultural registers, this article demonstrates that nuclear power not only reinforces global structures of racism and colonialism but also creates new articulations of white supremacy. It argues that a specific fantasy of nuclear genocide, seizing nuclear power as a means for executing a global race war, is an expression germane to the nuclear age. This article concludes by arguing that this fantasy plays an important role in white supremacist approaches to politics and existing forms of racist hierarchy.
