The epidemic of wars and military clashes from Syria to Yemen, the rising powers of China and Russia, and the turbulence in Pakistan, Central Asia and North Africa all underscore the urgent need for a highly professional intelligence agency within the European Union and between the EU and the UK in particular. However, the author shows that although the European Union introduced its common security policy more than two decades ago, EU member states mistrust each other and have failed to develop and fully integrate professional measures for intelligence-sharing to reduce security risks and the challenges of domestic radicalization and extremism.
