This book critically examines the significance of gender, race and sexuality to wars waged by liberal states. Drawing on original field-research with British soldiers, it offers insights into how their everyday experiences are shaped by, and shape, a politics of gender, race and sexuality that not only underpins power relations in the military, but the geopolitics of wars waged by liberal states. Linking the politics of daily life to the international is an intervention into international relations (IR) and security studies because instead of overlooking the politics of the everyday, this book insists that it is vital to explore how geopolitical events and practices are co-constituted, reinforced and contested by it. By utilising insights from Michel Foucault, the book explores how shared and collectively mediated knowledge on gender, race and sexuality facilitates certain claims about the nature of governing in liberal states and about why and how such states wage war against ‘illiberal’ ones in pursuit of global peace and security. The book also develops post-structural work in international relations by urging scholars interested in the linguistic construction of geopolitics to consider the ways in which bodies, objects and architectures also reinforce particular ideas about war, identity and statehood.
