Spheres of influence remain one of the most pervasive phenomena in the practice and history of international relations, yet only rarely have they been taken up analytically. To bring conceptual and discursive clarity, this article advances two arguments. First, it argues that spheres of influence are not a distinct form of hierarchy in international relations, but rather practices of control and exclusion that can be found within any ideal-type hierarchy. Second, these hierarchical practices are generally underspecified by those invoking the term. Different theoretical perspectives on international relations offer highly divergent ways of understanding control and exclusion, and all do so with plausible empirical mooring. Spheres of influence do not themselves denote a form of governance even if it does a form of order construction and maintenance. Any given empire, hegemonic order, or alliance may also be a sphere of influence depending on the practices that occur; the key is not to identify whether particular hierarchical traits are dispositive of one of these relational structures, but rather whether, and the extent to which, assertions of control and exclusion define the hierarchy.

Since its inception in 2000, the Women, Peace and Security (WPS) agenda has conceptualised the conflict-affected woman as a subject worthy of international attention, protection, and inclusion. In the wake of Europe's ‘refugee crisis’, this article examines how the remit of WPS has broadened from women in conflict zones to refugees in Europe's borderlands. A minority of European states now attend, in their WPS policy, to these conflict-affected women on the move. This inclusion productively challenges established notions of where conflict-affectedness is located. It exposes Europe as not always peaceful and safe for women, especially refugees who flee war. Conversely, the dominant tendency to exclude refugees from European WPS policy is built on a fantasy of Europe as peaceful and secure for women, which legitimises the fortressing of Europe and obscures European states’ complicity in fuelling insecurity at their borders, cultivating an ethos of coloniality around the WPS agenda. The inclusion of refugees is no panacea to these problems. If focused solely on protection, it repositions European states as protective heroes and conflict-affected women as helpless victims. The WPS framework nonetheless emphasises conflict-affected women's participation in decision-making and conflict prevention, opening space for recognising the refugee women as political actors.

Military attachés and wartime observers have received surprisingly little attention in international relations. Why do states exchange attachés, permitting uniformed foreigners to gather intelligence on their territory and during their wars? To explain, we adopt a broadly practice-theoretic approach, focusing on the individuals who developed the role by living it, showing how they both innovated a distinct military practice and established institutional legitimacy for attachés. We address an early historical case in which the practice proliferated: the Russo-Japanese War, throughout which observers represented multiple European states, on both sides of the conflict. Sometimes termed the first modern war, the conflict saw Japan's entry into the Eurocentric great power system. In this context, embedded attachés had a dual effect. On the one hand, a professional attaché community established itself: we show how local innovation by embedded officers, in the context of this structurally destabilising event, permitted the creation of a new institutional role that might otherwise have been impossible. On the other, the Japanese made use of the attachés as witnesses for Western governments, observing their performance of great power-hood, as they defeated Russia. The argument has implications for understanding both the military attaché system and communities of practice as such.

While there has been a long engagement with the impact of time on peacebuilding policies and practice, this engagement has to date focused predominately on issues of short- versus long-term initiatives, and of waning donor support for such initiatives. More recently, the critical peacebuilding turn has focused attention on the politics of the everyday as being essential to emancipatory endeavours enacted through localisation. Yet despite this, time itself has not been the subject of analysis, and the politics of time have not been integrated into the study of peacebuilding. This article, drawing both on historical institutionalist and on critical international studies analyses of temporality, provides a framework for analysing the impacts of time on the potential to achieve emancipatory peace. Drawing on extensive fieldwork in Bosnia and Herzegovina and in Cambodia, this article asserts that a focus on Policy Time, Liberal Political Time, and Intergenerational Time highlights how peacebuilding initiatives are framed by disparate timescapes that limit the visibility of local chronopolitics, and that this in turn restricts local empowerment and resistances.

Populists are on the rise across the globe and claim to speak on behalf of ‘the people’ that are set against the establishment in the name of popular sovereignty. This article examines how populist discourses represent ‘the people’ as a referent object that is threatened and the form and implications of this populist securitisation process. Drawing on securitisation theory and poststructuralism, the article understands populist securitisation as a discursive practice that propagates a politics of fear, urgency, and exceptionality in order to mobilise ‘the people’ against a ‘dangerous’ elite and normalise this antagonistic divide of the social space. While the proposed theoretical framework aims to clarify the relationship between poststructuralist and securitisation theory and capture the nexus between populism and security, the case of populism broadens the scope of potential subjects of security and poses important challenges to existing theoretical assumptions about security as something designated by states’ representatives and ‘security experts’. The article develops and illustrates its arguments with a case study on the (de)securitisation moves in the populist discourse of Donald Trump.

As staples of science fiction, space technologies, much like outer space itself, have often been regarded as being ‘out there’ objects of international security analysis. However, as a growing subset of security scholarship indicates, terrestrial politics and practices are ever more dependent on space technologies and systems. Existing scholarship in ‘astropolitics’ and ‘critical astropolitics’ has tended to concentrate on how such technologies and systems underpin and impact the dynamics of military security, but this article makes the case for wider consideration of ‘orbital infrastructures’ as crucial to conceptions and governance of planetary security in the context of the ‘Anthropocene’. It does so by outlining and analysing in detail Earth Observation (EO) and Near-Earth Object (NEO) detection systems as exemplary cases of technological infrastructures for ‘looking in’ on and ‘looking out’ for forms of planetary insecurity. Drawing on and extending recent theorisations of technopolitics and of Large Technical Systems, we argue that EO and NEO technologies illustrate, in distinct ways, the extent to which orbital infrastructures should be considered not only part of the fabric of contemporary international security but as particularly significant within and even emblematic of the technopolitics of planetary (in)security.

How do public protests emerge and become impotent? Inspired by Žižek's ideology critique, the article examines the ideological underpinnings of contemporary public-private security governance and suggests that worried, complaining subjects are a product of a dominant discourse of expert knowledge and technification. It then introduces three Žižekian dynamics that prevent protests from challenging the prevailing discourse – particularisation, ultra-politics, and cynicism – and illustrates these dynamic through a case study of the history of public complaints about Facebook. The article suggests that Facebook communicates through a discourse of technification whereby it constantly invents technological fixes unable to satisfy the complaints. The article further suggests that Facebook turning into a national security partner in the fight against terrorism online prevents complaints from becoming universalised by rendering even particularised privacy contestations illegitimate. This is reinforced, the article argues, by the subject's cynical enjoyment; that is, the ‘letting off steam’ on Facebook while criticising it.

These days, when we hear the slogan ‘let's make our country great again’ we almost automatically assume the state concerned is the US, and the leader uttering the slogan is President Trump. This article invites readers to explore the discourse and practices through which another national leader is seeking to restore his country's ‘greatness’ and promote national and international security. The leader concerned is France's Emmanuel Macron. Why focus on the French president? Because since his election he has become the most dynamic European leader, on a mission to enhance France's international stature, and to do so via a broader process of protecting and empowering the EU. More broadly, France stands out as a country whose political leadership has long been committed to the goal of playing a global role. As Pernille Rieker reminds us, ‘Since 1945, French foreign policy has been dominated by the explicit ambition of restoring the country's greatness [la grandeur de la France], justified in terms of French exceptionalism’.1

Macron has cast his vision of national/European greatness, security, and international order in opposition to the isolationist, rigidly nationalist visions articulated by his domestic opponents and, internationally, by President Trump. In his view, France and Europe can only be secure if they defeat the illiberal ideas advocated by the increasingly vocal political forces, particularly far-right movements, seeking to undermine the core values and multilateral principles of the post-1945 international order. Under these circumstances, an analysis of Macron's policies and practices of grandeur can help us gain a better understanding of the competition between liberal and illiberal worldviews – a competition that is increasingly pronounced within the Western world.

At present, most scholarship on the potential for escalation in cyberspace couches analysis in terms of the technological dynamics of the domain for relative power maneuvering. The result has been a conceptualisation of the logic of operation in cyberspace as one of ‘tit-for-tat’ exchanges motivated by attribution problems and limited opportunity for strategic gain. This article argues that this dominant perspective overlooks alternative notions of how cyber tools are used to influence. This, in turn, has largely led scholars to ignore second-order effects – meaning follow-on effects triggered by a more direct outcome of an initial cyber action – on domestic conditions, institutions, and individual stakeholders. This article uses the case of cyber-enabled political warfare targeting the United States in 2016 to show how escalation can occur as a second-order effect of cyber operations. Specifically, the episode led to a re-evaluation of foreign cyber strategy on the part of American defence thinkers that motivated an offensive shift in doctrine by 2018. The episode also directly affected both the political positions taken by important domestic actors and the attitude of parts of the electorate towards interference, both of which have reinforced the commitment of military planners towards assertive cyber actions.

Despite widespread public opposition to the Iraq War, numerous democracies joined the US-led multinational force. However, while some stayed until the end of coalition operations, and several increased their deployments over time, others left unilaterally. How to explain this variation? While some studies suggest that democratic defection from security commitments is primarily motivated by electoral incentives or leadership change, scholars have not reached a consensus on this issue. To account for the complex interplay between causal factors, this article develops an integrative theoretical framework, using fuzzy-set Qualitative Comparative Analysis (QCA) on original data on the Iraq War involvement of 51 leaders from 29 democracies. The findings document the existence of multiple paths towards coalition defection. Among others, the results show that: (1) leadership change led to early withdrawal only when combined with leftist partisanship and the absence of upcoming elections; (2) casualties and coalition commitment played a larger role than previously assumed; and (3) coalition defection often occurred under the same leaders who had made the initial decision to deploy to Iraq, and who did not face elections when they made their withdrawal announcements.

Prevention is a central pillar of the ‘Women, Peace and Security’ agenda, a policy architecture governing gender and conflict that is anchored in a suite of United Nations Security Council resolutions adopted under the title of ‘Women and Peace and Security’. In this article, I argue that prevention is currently constituted within the WPS agenda in multiple ways, all of which are organised in accordance with different logics: a logic of peace; a logic of militarism; and a logic of security. This presents prevention as a paradox, because in operation it collapses back into a logic of security, even as it is constructed and positioned as security's temporal and conceptual other. I provide a close reading of the WPS resolutions and show how the articulations of prevention across the agenda, and in certain resolutions, operate according to logics of security and militarism. The significance of such an argument is twofold: it lies both in the possibility of reconstruction of prevention in the WPS agenda according to different logics, and in the potential of undoing security – as the manifestation of prevention in practice – in queer, feminist, decolonial, and posthuman ways of knowing and encountering the world.

For well over twenty years, we have witnessed an intriguing debate about the nature of cyberspace. Used for everything from communication to commerce, it has transformed the way individuals and societies live. But how has it impacted the sovereignty of states? An initial wave of scholars argued that it had dramatically diminished centralised control by states, helped by a tidal wave of globalisation and freedom. These libertarian claims were considerable. More recently, a new wave of writing has argued that states have begun to recover control in cyberspace, focusing on either the police work of authoritarian regimes or the revelations of Edward Snowden. Both claims were wide of the mark. By contrast, this article argues that we have often misunderstood the materiality of cyberspace and its consequences for control. It not only challenges the libertarian narrative of freedom, it suggests that the anarchic imaginary of the Internet as a ‘Wild West’ was deliberately promoted by states in order to distract from the reality. The Internet, like previous forms of electronic connectivity, consists mostly of a physical infrastructure located in specific geographies and jurisdictions. Rather than circumscribing sovereignty, it has offered centralised authority new ways of conducting statecraft. Indeed, the Internet, high-speed computing, and voice recognition were all the result of security research by a single information hegemon and therefore it has always been in control.

The science of ammunition lethality is a field that seeks to define the point at which military ordnance takes life and produces death. By historicising lethality's epistemology, I reveal the intellectual fissures and scientific uncertainties that have been reified and embedded into contemporary conceptions of military power. This not only tells us something about the processes by which science is subordinated to war, but also offers a new lens from which to consider the way knowledge claims about battle are co-constructed and legitimated through military practices. As a result, this article places science back into a narrative that otherwise frames the ontology of war in terms of fighting.

Defence diplomacy represents a notable paradox. On the one hand, it is a cooperative activity to build strategic and moralistic trust between states and thus positively shape the environment in which foreign policy is made. On the other hand, defence diplomacy also involves competition and demonstrations of military power, which may contravene its goal of building moralistic trust and undermine confidence between states. This article deals with the latter competitive realpolitik elements of defence diplomacy in terms of secrecy, swaggering, and shows of force that have largely been ignored in the literature. Building on a theoretical discussion of whether defence diplomacy works, the case of peacekeeping in Southeast Asia is analysed to illustrate how defence diplomatic activities produce effects contrary to their stated aims.

The cyber realm is increasingly vital to national security, but much of cybersecurity is provided privately. Private firms provide a range of roles, from purely defensive operations to more controversial ones, such as active-cyber defense (ACD) and ‘hacking back’. As with the outsourcing of traditional military and security services to private military and security companies (PMSCs), the reliance on private firms raises the ethical question of to what extent the private sector should be involved in providing security services. In this article, I consider this question. I argue that a moderately restrictive approach should be adopted, which holds that private firms can justifiably launch some cybersecurity services – defensive measures – but are not permitted to perform others – offensive measures.

The emergence of new nuclear aspirants has posed a great threat to the post-Cold War global non-proliferation regime. These states have adopted a nuclear hedging strategy that has been deemed both strategically risky and politically difficult to maintain. Yet, hedging has not automatically resulted in nuclearisation. We analyse the conditions under which a nuclear hedger shifts its nuclear policy towards one of restraint. Drawing insights from prospect theory, we argue that a nuclear policy shift occurs when a nuclear hedger gains an asymmetric leverage vis-à-vis its adversary. Specifically, a hedging strategy that is based on loss aversion will only be abandoned when a shift in the nuclear aspirant's reference point occurs during negotiations. To test our theoretical arguments, we conduct an in-depth case study of North Korea's nuclear policies throughout the 1990s and 2000s. The empirical study of the changes in North Korea's negotiating stance during the Agreed Framework negotiations and the Six-Party Talks supports our asymmetric leverage thesis. We conclude with broad policy implications for the non-proliferation regime.

Some experts take on political mandates and simultaneously base their authority on a claim to independence: this balancing act enables international organisations (IOs) to incorporate ‘independent’ experts and generate ‘objective’ knowledge around their policies. However, how do these experts reconcile the contradictory roles of a mandated expert and an independent expert? I address this question by taking recourse to Goffman's sociology and two related concepts: sociological ambivalence refers to situations in which a person faces conflicting expectations. This conflict can be remedied through role distance, that is, behaviour that signals a degree of disaffection from the role one is currently performing while one simultaneously continues to perform that role. I conduct a case study of ‘independent’ experts hired by the UN Security Council to monitor sanctions, analysing how their position is sociologically ambivalent and how their knowledge practices are interlaced with performances of role distance. The findings have two implications for macro-phenomena: first, by keeping their contradictory role constellation functional, experts make it possible for IOs to mobilise ‘independent expertise’. Second, because experts perform role distance through the way they produce knowledge, role distance leaves traces in political knowledge.

Peacebuilding debates increasingly revolve around questions about knowledge and expertise. Of particular interest is what (and whose) knowledge(s) ends up authoritative in interventions. This article addresses a problem in the literature on the epistemics and epistemic authority of peacebuilding interventions: the acknowledgement of but lacking attention to plural knowledges, the transgressive character of expertise, and knowledge struggles. It does this by discussing recent suggestions that peacebuilding epistemic authority can be fruitfully analysed as a Bourdieusian field. The article identifies a tension in Bourdieu's own thinking about fields, which has shaped some of these recent proposals. This tension, nevertheless, also enables a reconsideration of fields and struggles, and thereby an analysis that takes plurality and transgressiveness into account. By developing such an alternative conceptual position, the article sees peacebuilding epistemic authority as object- and struggle-bound; conditioned and dependent on dynamics that go beyond peacebuilding as a distinct field of practice. This position is illustrated in an analysis of the emergence and (temporary) establishment of epistemic authority in peacebuilding interventions on informal economies.
