What are the politics involved in a government justifying its use of military force abroad? What is the role of international law in that discourse? How and why is international law crucial to this process? And what role does the media have in mediating the interaction of international law and politics? This book provides a fresh and engaging answer to these questions. It introduces different actors to the study of international law in this context, in particular highlighting the importance of institutional actors and the role of the media. It takes a theoretical approach, informed by detailed empirical analysis of key case studies, which challenges the traditional distinction between the spheres of 'the international' and 'the domestic' in global affairs, and the role of international law in the making of public policy.
