The Liberal International Order is in crisis. While the symptoms are clear to many, the deep roots of this crisis remain obscured. We propose that the Liberal International Order is in tension with the older Sovereign Territorial Order, which is founded on territoriality and borders to create group identities, the territorial state, and the modern international system. The Liberal International Order, in contrast, privileges universality at the expense of groups and group rights. A recognition of this fundamental tension makes it possible to see that some crises that were thought to be unconnected have a common cause: the neglect of the coordinating power of borders. We sketch out new research agendas to show how this tension manifests itself in a broad range of phenomena of interest.

Our primary aim in this article is to explore vernacular constructions of Europe’s so-called ‘migration crisis’ from the grounded everyday perspectives of EU citizens. We do so as a critical counterpoint to dominant elite scripts of the crisis, which are often reliant upon securitised representations of public opinion as being overwhelmingly hostile to migrants and refugees and straightforwardly in favour of tougher deterrent border security. In addition to broadening the range of issues analysed in vernacular security studies, the article seeks to make three principal contributions. Theoretically, we argue for an approach to the study of citizens’ views and experiences of migration and border security that is sensitive to the performative effects of research methods and the circular logic between securitising modes of knowledge production and policy justification. Methodologically, we outline and apply an alternative approach in response to these dynamics, drawing on the potential of critical focus groups and a desecuritising ethos. Empirically, we identify a vernacular theory of ‘the border’ as information management, and a significant information gap prevalent among participants with otherwise opposing views towards migration. These findings challenge bifurcated understandings of public opinion towards migration into Europe and point to the existence of vernacular border security imaginaries beyond either ‘closed’ or ‘open’ borders.
