Globalization and economic integration are putting the American and European economies in ever closer competition. Meanwhile, the end of the Cold War has removed the traditional glue for transatlantic cooperation. This book asks whether the trend will be toward increased conflict or collaboration. Will policymakers in Europe and the United States be encouraged by their mutual interests to collaborate in the pursuit of common goals? Or will competition fan conflict and recrimination now that the Cold War has ended and their common enemy has disappeared?
