This book presents an important contribution to our understanding of post-conflict justice as an essential element of global ethics and justice through an exploration of the World Tribunal on Iraq (WTI). The 2003 War in Iraq provoked worldwide protests and unleashed debates on the war’s illegitimacy and illegality. In response, the WTI was organized by anti-war and peace activists, international law experts, and ordinary people who claimed global citizens’ rights to investigate and document the war responsibilities of official authorities, governments, and the United Nations, as well as their violation of global public will. The WTI’s democratizing, experimental form constituted reclaimative post-conflict justice, a new conceptualization within the field of post-conflict and justice studies. This book serves as a theoretical and practical guide for all who seek to reclaim deliberative democracy as a viable foundation for revitalizing the ethical norms of a peaceful and just world order.
