The problems of peacekeeping in Somalia, Rwanda and former Yugoslavia marked a turning point for major powers in international military peacekeeping. Major support for a more pro-active UN role in peacekeeping has not been forthcoming and where major power involvement is deemed vital, non-UN peace operations have increasingly become the norm. This valuable volume explores the continuing significance of peacekeeping in international affairs, particularly in terms of its military dimensions, and examines the priorities and perspectives of the major powers in relation to their military participation in international peacekeeping and wider peace operations in the twenty-first century. It is ideal for scholars and students interested in contemporary international politics, international relations, international organizations, security and strategic studies, conflict resolution and foreign policy analysis.
