Tracing the transformation of NATO in the aftermath of the Cold War, this volume assesses NATO's current accomplishments, continuing challenges and political pitfalls. International scholars and policy-makers explore three key themes influencing NATO's future: transatlantic relations, the debate over enlargement and the organization's new functions. Weighing the fate of an alliance poised for renewal or decline, the contributors offer analysis and discussion of an organization that has changed profoundly over the past five years and continues to evolve in the face of an uncertain global environment.
