The EU as an International Counterterrorism Actor: Progress and Constraints

During the first decade after the 9/11 attacks, the European Union (EU) has developed into an international counter-terrorism actor in its own right, a role increasingly accepted by third countries. This is a result of many influences, including a more favourable legal basis after the Amsterdam Treaty reforms; enhanced institutional capabilities, such as the growing importance of the Counter-Terrorism Coordinator; the use of a broad range of instruments, such as intelligence sharing; and the application of geopolitical priorities, guided by meetings at the United Nations and the Council of Europe ( among other fora). At the same time, the EU's counter-terrorism role has remained subsidiary, both legally and politically, to that of its member states. Furthermore, a lack of its own operational capabilities, its institutional complexity, and its problems of cross-policy coordination continue to act as powerful constraints on the EU's counter-terrorism responsibilities.
