At a critical time for the identity and policy direction of the EU, this Handbook examines the dynamics behind the development of the Common Foreign and Security Policy (CFSP) and the Common Security and Defence Policy (CSDP). The Handbook includes chapters from renowned scholars that examine the efficacy and visibility of the EU as a diplomatic, military and civilian actor in a turbulent world. The authors? original contributions address the impact that existing frameworks, structures and procedures have on the effectiveness of the EU as an international actor and consider the legal challenges to the EU's integrated approach to external action. The Research Handbook on the EU?s Common Foreign and Security Policy brings together scholars from different areas of law (EU and international law) and from the political science field. The interdisciplinary approach makes it essential reading for scholars of law, political science and international relations. Policymakers and all those with an interest in the workings of the EU?s legal services will also find this an insightful resource. Contributors include: S. Blockmans, M. Broberg, M.E. Canamares, M.
