This book provides a comprehensive coverage of crucial issues concerning EU co-operation and European security. At present, Europe is confronted with a number of serious common and global challenges, the most important being the economic crisis, migration issues, geopolitical tensions at its external borders, terrorism, climate change and environmental challenges. These developments have a huge impact on the stability and security of the continent as a whole and on each individual European country. Europe, more particularly the European Union, has to organize its governance and security infrastructure in such a way that it can cope with these global threats. This edited volume collects a number of topics and themes connected to the governance and/or security dimensions of EU co-operation.
