The 1967 Outer Space Treaty reserved outer space for ‘peaceful purposes’, yet recent decades have witnessed growing competition and calls for new multilateral rules including a proposed ban on the deployment of weapons in space. These diplomatic initiatives have stalled in the face of concerted opposition from the United States. To explain this outcome, we characterise US diplomacy as a form of ‘antipreneurship’, a type of strategic norm-focused competition designed to preserve the prevailing normative status quo in the face of entrepreneurial efforts. We substantially refine and extend existing accounts of antipreneurship by theorising three dominant forms of antipreneurial agency – rhetorical, procedural, and behavioural – and describing the mechanisms and scope conditions though which they operate. We then trace the development of US resistance to proposed restraints on space weapons from 2000–present. Drawing on hundreds of official documents, we show how successive US administrations have employed a range of interlayered diplomatic strategies and tactics to preserve the permissive international legal framework governing outer space and protect US national security priorities. Our study illustrates the specific techniques and impacts of resistance in a domain of growing strategic importance, with implications for further refining understandings of norm competition in other issue areas.

The emergence of military ad hoc coalitions (AHCs) in Africa as a tool for conflict management outside established institutional frameworks brings about a number of questions: are they undermining existing security structures such as the African Peace and Security Architecture (APSA) or are they contributing to further regime complexity? In order to answer these questions, the article applies the logic of functional differentiation as it is used in the literature on regime complexity and inter-organisational studies. Scope conditions are developed exploring when and how functional differentiation operates and what consequences it brings about for interacting institutions. Empirically the example of military ad hoc coalitions in the Lake Chad Basin and Sahel is at the centre of analysis. It will be argued that ad hoc coalitions are part of a functionally differentiated system response within the African Security Regime Complex and not in direct competition to the APSA.

Strategic narratives are employed by political actors as tools to pursue their goals, constructing a shared meaning of the past, present, and future in order to shape behaviour. Building on discourse analysis of the magazine Dabiq and from in-depth, semi-structured interviews conducted between 2018 and 2019 with IS civilian employees and civilians living in IS-controlled territory, we analyse how IS organised its strategic narrative of governance and statebuilding around three main themes considered as central in the statebuilding literature – the provision of security, the provision of basic services, and social cohesion – and how such a strategic narrative was received by citizens living in IS-controlled territory. We argue that the study of strategic narratives of governance and statebuilding casts light on the factors leading to the success or demise of emergent statebuilding efforts, equally demonstrating how IS’s project is quite conventional when compared to other mainstream statebuilding narratives.

The article calls on academics and policymakers who focus on mass atrocity prevention to engage with Trust Studies. This is needed because trust and distrust are commonly identified as a significant factor in destruction processes, yet there remains no substantive engagement with these concepts. The article combines Trust Studies, interdisciplinary research on the Central African Republic (Anthropology, Sociology, African Studies, and Political Science), and primary sources to analyse social and political trust dynamics through an exploration of (a) leadership, (b) outsourcing, (c) identity politics, and (d) witchcraft. It makes a twofold contribution. First, it provides a more informed understanding of the mass violence that took place in the Central African Republic through a historical analysis of trust dynamics. Second, it considers the implications for mass atrocity prevention, as it argues that the mainstream commitment to ‘rebuilding trust’ is built on misguided assumptions. The case study holds broader implications for both Trust Studies and mass atrocity prevention. Ultimately, it calls for interdisciplinary research to aid our collective understanding of the multifaceted roles that trust and distrust play in mass violence.

Drawing on recent debates in English School (ES) theory, this article develops an analytical framework for examining how states use multilateral institutions, or what ES theorists call ‘secondary institutions’, to reshape ‘primary institutions’, i.e. fundamental practices in international society. The framework highlights the role of states’ agency in international institutional change by shedding light on strategies that they employ to bring about changes in primary institutions. It posits that, although they can seek to directly remould primary institutions, states in practice often seek to bring about primary institutional changes through existing or newly formed secondary institutions and that this is especially the case at the level of regional international societies (RISs). The article demonstrates the utility of the framework by using it to analyse the case of Russia’s peacekeeping policy in the post-Soviet regional international society (PSRIS), focusing on its efforts to institutionalise the Collective Security Treaty Organization (CSTO) as an alternative ‘peacekeeping’ actor.

The 1979 Islamic Revolution was a tectonic change that influenced the geopolitics of the Middle East to this day. This article highlights the necessity of re-examining the events of 1979 from a securitisation perspective. Through an investigation of Ayatollah Khomeini's pivotal role, I challenge the methodological nationalism often found in the study of Israel–Iran relations. Despite his unconventional position in security matters, Khomeini played a crucial role in the securitisation of the 1979 revolution. Drawing on Israeli Ministry of Foreign Affairs archives, secondary sources, elite interviews, and Khomeini's theological speeches, this article re-examines the intricate stages of securitisation and counter-securitisation spanning 16 years. Khomeini effectively mobilized the political audience (Iranian people) to support the revolution, aiming to overthrow the Shah and remove Israel’s presence from Iran. I argue that a non-linear securitisation process was employed, characterised by Khomeini's ability to establish informal authority among the opposition. This process ultimately led to him gaining legitimacy from the Iranian people and culminated in the successful securitisation act of the 1979 Islamic Revolution.

The role of performance in ontological security seeking is underdeveloped, despite the fact that many elements of such behaviour – narratives, rituals, routinised meetings – carry a distinctive performative quality. Drawing on Butlerian performance theory, this article makes the case that performances are essential to re-establishing coherence and a sense of self following ontologically critical situations. The reproduction of the self, especially while directly addressing fundamental existential questions, is an important way to overcome critical situations. At the state level, this reproduction of self also includes a reproduction of the international system, a task which is best enacted in everyday diplomatic practice. To explore this theory, I use Brexit as an illustrative case study. Brexit was a moment of profound crisis for the United Kingdom (UK) and an ontologically critical situation. It forced the UK to reposition itself on the world stage and confront significant challenges to its self-understanding. In Westminster, these efforts centred on ‘Global Britain’ – a narrative shift that bridged the identity gap and provided a thin framework for foreign policy. At the same time, British diplomats were tasked with international realignment post-Brexit. In this way, everyday diplomatic practice became Brexit performances.
