On the occasion of the twenty-fifth anniversary of the Netherlands Institute of International Relations 'Clingendael' The Netherlands Institute of International Affairs 'Clingendael' celebrates its 25th anniversary in 2008. This is not only a reason to look in retrospect, but also to look into the future. In this book, research fellows from the Institute shed some light on the near future regarding their research topics. Various themes in the field of Diplomacy, European integration, Security, and Energy are dealt with. In the tradition of the Clingendael Institute, being a policy-relevant think-tank, the different contributions to this book are not hypothetical foresights written from an ivory tower, but thought-provoking, policy-oriented chapters that will be relevant to anyone interested in international relations. Prof. Dr Jaap de Zwaan is Director of the Clingendael Institute, Dr Edwin Bakker is Head of the Clingendael Security and Conflict Programme, Sico van der Meer MA is a Research Fellow in the Clingendael Security and Conflict Programme.
