"As with all Oxford Handbooks, this publication masters its enormous task with precision and elegance, providing readers with insightful summary chapters in Part I, followed by highly readable case studies in chronological order of the peacekeeping operations in Part II . . . the editors and writers have made an important contribution to promote such an understanding among the UN member states." - Helmut Volger, PassBlue Blog

"These chapters cover extensive ground and provide an up-to-date perspective on peacekeeping and international security. They also succeed in dispelling the conceptual confusion that prevails in some corners of the literature on peace missions . . . The book brings together an impressive group of academics and practitioners including leading scholars, senior diplomats and military officers with first-hand experience in UN peace operations." - Patrick A Mello, Political Studies Review
