This book explores the concept of ‘resilience’ in the context of militaries and militarization. Focusing on the U.S., Britain, Canada, Australia, and continental Europe, it argues that, post-9/11, there has been a shift away from ‘trauma’ and towards ‘resilience’ in framing and understanding human responses to calamitous events. The contributors to this volume show how resilience-speech has been militarized, and deeply entrenched in imagined communities. As the concept travels, it is applied in diverse and often contradictory ways to a vast array of experiences, contexts, and scientific fields and disciplines. By embracing diverse methodologies and perspectives, this book reflects on how resilience has been weaponized and employed in highly gendered ways, and how it is central to neoliberal governance in the twenty-first century. While critical of the use of resilience, the chapters also reflect on more positive ways for humans to respond to unforeseen challenges.
