Enlargement will change the nature of the European Union, but how will it affect international affairs? The EU and its member states can work together on international questions when they choose to do so. They command significant economic resources and have launched a Common Foreign and Security Policy. Yet the demands of taking on ten new countries, managing the aftermath of national referenda on a constitutional treaty, and ameliorating the acrimony after the war in Iraq all complicate efforts to enhance the EU's international presence.

In this book twenty authors from Europe and North America consider the impact of EU enlargement on the EU's perception of its international role, on specific geographical regions, and on a range of global issues. Has the latest enlargement affected strategic priorities? Do perspectives differ in different regions of Europe? How has enlargement affected relations with the United States, Russia, Turkey, or the Middle East? Will a larger EU be as active a supporter of development assistance or international environmental policies? Will the EU's role change at the United Nations?
