This book arrives at a very significant time throughout Europe. Not only is the European Union currently facing a prolonged economic and social crisis, with nascent political consequences, such as the ascension of populist parties in the 2014 European elections, but also its Eastern neighbourhood is confronted with the growing hostility of an assertive Russia, opposing any new advance of the West towards its frontiers. Bringing together experts in fields such as international relations, political science, political sociology, diplomacy, security studies, and European studies, with robust academic and professional backgrounds and expertise with regard to the region, this volume explores this significant “window of opportunity”, and will undoubtedly appeal to a global audience. The considerable diversity of approaches and styles here allows a multidimensional diagnosis and analysis of present-day Eastern Europe. This volume defines a series of major regional opportunities, vulnerabilities and dilemmas, and explores the complex perspectives of the “new Eastern Europe”, located between the European Union and Russia, under its current name of the EU’s Eastern Neighbourhood, along with the tensions and challenges of a possible second Cold War.
