The Kosovo war has concentrated new attention on the transatlantic relationship and its principal institution, NATO. NATO has admitted new members and adopted a new strategy, giving it a broader and more interventionist role than Europeans have been used to. Mean-while, proposals to formulate a distinctive European Union foreign policy and defence identity could irritate the security relationship with North America that has lasted for fifty years. A struggle among Europeans for control of Europe's future is bound up with management of the euro and arguments over integration and enlargement of the EU. The threat of a transatlantic trade war suggests the struggle is threatening to disrupt the Atlantic relationship. Will the Atlantic Community strengthen or weaken under these strains? In this book, distinguished experts consider the arguments over enlargement of NATO and the European Union, and the course of European integration and transatlantic trade, in order to assess the state of this vital relationship and its future.
