Diverse, sometimes even contradictory concepts and practices of resilience have proliferated into a wide range of security policies. In introducing this special issue, we problematize and critically discuss how these forms of resilience change environments, create subjects, link temporalities, and redefine relations of security and insecurity. We show the increased attention – scholarly as well as political – given to resilience in recent times and provide a review of the state of critical security studies literature on resilience. We argue that to advance this discussion, resilience needs to be conceptualized and investigated in plural terms. We use temporalities and subjectivities as key analytical aspects to investigate the plural instantiations of resilience in actual political practice. These two issues – subjectivity and temporality – form the overall context for the special issue and are core themes for all the articles collected here.
