"I have seen the UN perform on a changing global stage in many UN missions. This book examines how the UN must continue to evolve amongst changing state actors, differing regional organisations and a constant global paradigm shift. It is essential material for enhancing one's understanding of the nature of international conflict and for the continued relevance of the UN as a key stakeholder and participant in world affairs."--Maj. Gen. Kristin Lund, Head of Mission and Chief of Staff, UN peacekeeping mission in the Middle East (UNTSO) "This outstanding collection is a must-read for anyone interested in the central challenges of peacekeeping today. From big ideas about changes in global order, to more focused analyses of policing and the protection of civilians, this book provides a comprehensive overview of where peacekeeping is now, and what we may expect in the future."--Lise Morj
