In order to advance intersectional approaches to war and security which foreground feminist questions, this course puts transnational and postcolonial feminist theory and praxis into conversation with critical approaches to security, war and militarism. We will interrogate the binary constructions of masculinity and femininity upon which war and systems of militarism depend as well as how such gendered constructions are always intersected with other systems of power such as race, sexuality, capitalism and (neo)colonialism. After an introduction to foundational theoretical scholarship in both transnational feminism and critical security studies, the course will examine contemporary issues which preoccupy feminist scholars focused on war and security. Such topics might include: the 'global war on terror' and the countering violent extremism agenda; sex work and migration; normative policy instruments on women, peace and security; arms control; sexual violence; women as agents of violence; the militarization of humanitarianism and development; and critiques of (neo)liberal peacebuilding. Ultimately, the goal of this course is to suggest productive, feminist interventions into the study of war and security and to equip students with the tools to engage in such interdisciplinary theorizing and practice.
