This book offers an in-depth study on the deployment of military operations in the framework of the European Unionâs Common Security and Defence Policy (ESDP/CSDP). While existing studies of the subject are either descriptive or focused on a single level of analysis this book incorporates factors from three different levels of analysis to explain the deployment of ESDP military operations. First the international level where the emergence of events that threaten certain values held dear by EU member states catalyses the process leading to an operation; second the national level where the member states formulate their initial national preferences towards a prospective deployment based on national utility expectations; and third the EU level where the member states come to negotiate and seek compromises to accommodate their different national preferences towards a deployment. The strength of this multi-level collective action approach is demonstrated by four in-depth military case studies which analyse the preference formation of France Germany and the UK towards the deployments of Operation Althea in Bosnia and Herzegovina Operation Artemis and EUFOR RD Congo in the Democratic Republic of the Congo (DRC) and Operation Atalanta off the coast of Somalia respectively. The author draws on a wealth of primary sources including over 50 semi-structured interviews conducted with national and EU officials during 2011-15 and provides an up-to-date overview and critique of the existing theoretical literature on the deployment of ESDP/CSDP military operations. This book will be of much interest to students of European security EU politics military and strategic studies and International Relations in general. . Language: English
