How does gender equality manifest within peace and security? A few scholars have investigated the diffusion and operationalization of the Women, Peace, and Security (WPS) agenda at the international, regional, and national levels, but not a lot of attention has been given to interrogating the trajectory of gender equality within the WPS agenda. In Finding Gender Equality in the Women, Peace, and Security Agenda, Barbara Trojanowska carefully unpacks the slow and highly politicized operationalization of gender equality in peace and security, from the international down to the regional and national levels. Trojanowska does so by providing a comprehensive account of the WPS implementation of the United Nations (UN) Security Council, Pacific Islands Forum (PIF), Association of Southeast Asian Nations (ASEAN), and governments of the Philippines and Australia.
