This book examines cooperation between the United States and Europe on a range of global issues. With the Soviet threat no longer a unifying factor, the transatlantic partners have sought a new basis for acting together in the post-Cold War era. The conditions and strategies that determine the success or failure of cooperation in: restructuring relations with the East; countering the threat of weapons proliferation; dealing with so-called 'rogue' states; and managing the global economy, are explored.
