This book asks scholars to reexamine international conflict and its management-in order to move the field toward directly theorizing about and examining the interdependence between conflict events and conflict management attempts. Despite decades of work, research on international conflict and its management remains siloed in three fundamental ways. First, scholars do not thoroughly address international conflict dynamics within studies of conflict management, even though the former give rise to the latter. Second, existing work generally investigates one conflict management strategy (e.g., mediation) at the expense of others (e.g., adjudication). These strategies, however, are not independent of one another; they exist on a single menu from which potential third parties choose. Third parties therefore implicitly-if not explicitly-consider and select among the various strategies when deciding how to manage a conflict, thereby inviting and incorporating comparisons. Finally, researchers tend to treat conflict management efforts-even within the same conflict-as independent events, even though some efforts (e.g., adjudication or arbitration) follow and explicitly relate to other, earlier efforts (e.g., an earlier negotiation or mediation). In short, elements of sequencing and interaction influence conflict management, even as scholars rarely consider such elements. This book will be of great value to scholars and researchers of Political Science, International Relations and Conflict Management and Resolution. The chapters in this book were originally published as a special issue of International Interactions.

Since the 1990s, the international security environment has shifted radically. Leading states no longer play as great a role in regional conflicts, and thus a new opportunity for regional conflict management has opened. This collection of original essays is one of the first to examine the implications and efficacy of regional conflict management in the new world order. The editors' general overview provides a framework for analyzing regional conflict management efforts and the kinds of threats faced by actors in different regions of the world. Case studies from every major world region then place these factors into specific regional contexts and address a variety of challenges. Drawing together a diverse group of scholars from around the world, Regional Conflict Management provides key lessons for understanding conflict management over the globe.

The Puzzle of Peace moves beyond defining peace as the absence of war and develops a broader conceptualization and explanation for the increasing peacefulness of the international system. The authors track the rise of peace as a new phenomenon in international history starting after 1945. International peace has increased because international society has developed a set of norms dealing with territorial conflict, by far the greatest source of international war over previous centuries. These norms prohibit the use of military force in resolving territorial disputes and acquiring territory, thereby promoting border stability. This includes the prohibition of the acquisition of territory by military means as well as attempts by secessionist groups to form states through military force. International norms for managing international conflict have been accompanied by increased mediation and adjudication as means of managing existing territorial conflicts.

This widely used and acclaimed text reader brings together some of the best work on the onset of war, the expansion of war, the conditions of peace, and the termination and impact of war. Editorial commentary on the major findings and the statistical analysis used in each study teaches students how to read the article so that they can become literate in social science methods. A learning package in the appendix provides a programmed text to teach students how to interpret tables, read basic statistics, and conduct elementary data analysis. Correlates of War data on European countries is provided, and a methodological table of contents allows instructors to assign articles from the easiest (simple percentages) to the most advanced (time series and formal modeling).

The contemporary world is beset with a wide variety of conflicts, all of which have features without historical precedent. While most accounts of peacekeeping focus on attempts to limit violent conflict, this traditional view hardly captures the variety of challenges that today's peacekeepers face. Peacekeepers are now thrust into the unconventional roles of monitoring elections, facilitating transitions to the rule of law, distributing humanitarian aid, and resolving conflicts in civil societies that are undergoing transformation. This is the context for understanding the activities of modern-day peacekeepers. In When Peacekeeping Missions Collide, Paul F. Diehl, Daniel Druckman, and Grace B. Mueller provide an original and comprehensive assessment on how different peacekeeping missions intersect with one another in contemporary conflicts. They begin by documenting the patterns of peacekeeping missions in 70 UN operations, noting the dramatic increase in number and diversity of operations since the end of the Cold War as well as the shift to conflicts with a substantial internal conflict component. They then turn to the overarching question of the book: how do individual peacekeeping missions impact the outcomes of other missions within the same operations? To answer this, the authors have developed a novel dataset of UN peace operations from 1946-2016 to assess mission compatibility. Moreover, the authors utilize five detailed case studies of UN peacekeeping operations featuring mission interdependence and then measure the results against their theoretical expectations. Ultimately, the model they have developed for analyzing the effectiveness of the far more complex peace operations of today—relative to the simpler operations of the past—is essential reading for scholars of peacekeeping and conflict management.

Paul F. Diehl and Charlotte Ku's new framework for international law divides it into operating and normative systems. The authors provide a theory of how these two systems interact, which explains how changes in one system precipitate changes and create capacity in the other. A punctuated equilibrium theory of system evolution, drawn from studies of biology and public policy studies, provides the basis for delineating the conditions for change and helps explain a pattern of international legal change that is often infrequent and sub-optimal, but still influential.

Since the end of the Cold War, US officials have been more willing to remind allies that the US will not play the role of international policeman. Given US reluctance, the job of peacekeeping will fall increasingly to international organizations and regional alliances. In this book, Diehl examines the recent record of United Nations peacekeeping forces and develops criteria for assessing their operations. His analysis aims to provide useful guidance for the management of new hostilities in areas such as Central and Eastern Europe, where the dissolution of the Soviet Union has spawned bitter civil wars and dangerous border disputes. Diehl identifies three sets of factors that affect traditional international peacekeeping operations. He begins by discussing the practical concerns of peacekeeping efforts, such as force composition, organization and deployment. He then examines issues related to the political and military context in which the forces are deployed, including the nature of the conflict and the involvement of third parties. Finally, he considers the authorization by the relevant international body - usually the UN - as it relates to the mission's mandate, policies and financing. He concludes by analyzing the viability of new roles for UN peacekeeping troops, such as humanitarian assistance, and by exploring structural alternatives to UN peacekeeping operations. This paperback edition includes a new epilogue which examines peacekeeping operations in Bosnia, Somalia and Cambodia.
