What will be the future of security cooperation in Europe after the Bush Administration? Is the famous rift between 'Old Europe' and America too great to repair? Is the European Union ready to assume a more prominent place on the world stage? This book explores the key security challenges confronting Europe, from relations with the United States and Russia to the use of military force and the struggle against terrorism. In the future, European states will increasingly act alone, independent of America, on security matters. In doing so, they will prefer to operate through the institutional machinery of the EU, which is ascendant as an instrument of security coordination in Europe. NATO, the institutional vehicle of a troubled transatlantic relationship, is in decline. Europe is likely to act not in defiance of America, but in deference to America. But it will act alone, when circumstances favour such a choice.
