Book excerpt: The September 11 attacks in the USA lent huge impetus to efforts to coordinate and expand the EU's counter-terrorism role, bringing about far-reaching cooperation and pushing the EU down the track of further European integration. In setting out the EU's achievements in the fight against terrorism, the chapters in this book explain how and why this has come about and the mechanisms involved. They also critically assess the limits of such integration and explore the tensions between co-operation and the issue of individual human rights. A selection of key documents rounds out the book with a valuable reference dimension. This book brings together key thinkers and is a welcome analysis of terrorism challenges.
