NATO’s approach to Women, Peace and Security (WPS) has developed significantly since it first adopted a policy on the topic in 2007. From a much problematized ‘add women and stir’ approach to improve operational effectiveness in Afghanistan, it has become a prominent feature of the alliance’s new Strategic Concept adopted at the Madrid Summit. Here NATO reiterated its commitment to integrate the WPS agenda across all tasks and ‘to continue to advance gender equality as a reflection of our values.’ WPS should therefore form a core part of NATO’s changing priorities, primarily in response to the full-scale Russian invasion of Ukraine in early 2022. Yet where we might have expected to see NATO leadership commit to include WPS as part of their response, in particular the defense of ‘Western values,’ we have instead seen WPS marginalized by the Alliance despite stated policy commitments.
