The United States of America and the European Union are partners in a world undergoing rapid changes. The need for cooperation based on trust requires better information about each other and permanent contacts with one another. In this book the Konrad-Adenauer-Stiftung and the Johns Hopkins Center for Transatlantic Relations have asked authoritative personalities from the European Council, the European Commission and the European Parliament to share their insights. This book is also meant as an indispensable compendium of the major European institutions and a praxis-oriented handbook for establishing contacts with key European opinion leaders.
