This book offers a major new analysis of how peace and security can be maintained in Europe and provides a radical vision of a technology-enabling future European defence. It weaves history, strategy, policy, and technology into a compelling analytical narrative and lays out the scale of the challenge Europeans and their allies face. This authoritative book offers a radical and timely new vision for the transatlantic defense relationship. The authors call upon Europeans to more fully share the burdens of NATO, for only then can the United States continue to underwrite Europe's peace while meeting the growing array of challenges beyond Europe. Americans and Europeans must move beyond narrow debates and together consider the fast changing character of war and peace.
