There is a growing recognition that globalization is leading to fundamental changes in world order, creating new imperatives and requiring new ways of understanding the international system. Two of the most important actors in the contemporary international system are the United States and Europe, and their relationship is fundamental in shaping international order. International order shapes, and is also being shaped by, the forces of globalization, whether cultural, political or economic. This volume examines issues that transcend national and cultural boundaries, discussing international order from the perspective of the English School of International Relations. It covers areas such as: great powers' foreign policy; relations among great powers; sovereignty, democracy and legitimacy; international terrorism and intelligence; and institutions and international organizations. Ultimately, it analyzes what is to be done to assure a stable international order. The volume is relevant to security studies, foreign policy, transatlantic relations and international organizations, as well as international relations theory.
