When powerful states and international organizations decide to respond to violent conflict around the world, their preferred policy instrument is to deploy peace operations -- institutions that must serve both the international politics of their creation as well as the fractured local societies they aim to transform. But while their international face has been widely analysed, we know less about how peace operations function 'on the ground.' In How Peace Operations Work, Jeni Whalan addresses this critical dimension of peacekeeping. She analyses the effectiveness of peace operations through a local lens, asking new questions about how they work, and generating new insights about how they might be made to work better. What emerges is the overriding importance of local legitimacy -- the perception among local actors that a peace operation, its personnel, and its objectives are right, fair, and appropriate. How Peace Operations Work demonstrates that when local actors perceive a peace operation to be legitimate, they are more likely to help the operation achieve its goals. This book combines novel theoretical progress with rich empirical work, drawing on in-depth case studies of the United Nations Transitional Authority in Cambodia (UNTAC) and the Regional Assistance Mission to Solomon Islands (RAMSI) to propose a new approach to studying the effectiveness of peace operations, and a set of practical recommendations that challenge key elements of prevailing peace operations policy.

"Fortna demonstrates that peacekeeping is an extremely effective policy tool, dramatically reducing the risk that war will resume. Moreover, she explains that relatively small and militarily weak consent-based peacekeeping operations are often just as effective as larger, more robust enforcement missions. Fortna examines the causal mechanisms of peacekeeping, paying particular attention to the perspective of the peacekept--the belligerents themselves--on whose decisions the stability of peace depends."--publisher website.

Making War and Building Peace examines how well United Nations peacekeeping missions work after civil war. Statistically analyzing all civil wars since 1945, the book compares peace processes that had UN involvement to those that didn't. Michael Doyle and Nicholas Sambanis argue that each mission must be designed to fit the conflict, with the right authority and adequate resources. UN missions can be effective by supporting new actors committed to the peace, building governing institutions, and monitoring and policing implementation of peace settlements. But the UN is not good at intervening in ongoing wars. If the conflict is controlled by spoilers or if the parties are not ready to make peace, the UN cannot play an effective enforcement role. It can, however, offer its technical expertise in multidimensional peacekeeping operations that follow enforcement missions undertaken by states or regional organizations such as NATO. Finding that UN missions are most effective in the first few years after the end of war, and that economic development is the best way to decrease the risk of new fighting in the long run, the authors also argue that the UN's role in launching development projects after civil war should be expanded.

The volume is the first comprehensive overview of multiple theoretical perspectives on UN peace operations, with two main uses. First, it provides practical examples of how International Relations theories - realism, liberal institutionalism, rational choice institutionalism, sociological institutionalism, constructivism, practice theories, critical security studies, feminist institutionalism, and complexity theory - can be applied to a specific policy issue. Second, it demonstrates how major debates on UN peace operations - regarding protection of civilians, local ownership, or gender mainstreaming - benefit from a theoretical exploration. The volume is aimed at three audiences: scholars who want to keep up to date with the latest research on UN peace operations; undergraduate and postgraduate students who either seek to understand International Relations theories in general or are interested in UN peace operations..

Dennis C. Jett examines why peacekeeping operations fail by comparing the unsuccessful attempt at peacekeeping in Angola with the successful effort in Mozambique, alongside a wide range of other peacekeeping experiences. The book argues that while the causes of past peacekeeping failures can be identified, the chances for success will be difficult to improve because of the way such operations are initiated and conducted, and the way the United Nations operates as an organization. Jett reviews the history of peacekeeping and the evolution in the number, size, scope, and cost of peacekeeping missions. He also explains why peacekeeping has become more necessary, possible, and desired and yet, at the same time, more complex, more difficult, and less frequently used. The book takes a hard look at the UN's actions and provides useful information for understanding current conflicts.

Explains how peacekeeping can work effectively by employing power through verbal persuasion, financial inducement, and coercion short of offensive force.

This book offers the most comprehensive study to date of peacekeeping over time and across all regions of the world.
