A rapidly-changing nation and a key player in the Middle East, Turkey has long been centrally important to both the United States and the European Union. A major partner both of the EU and Turkey, the US has also been the most ardent and committed supporter of closer ties between them. Yet while Turkey's relations with the US and the EU have been intimately linked, they have not proceeded along two parallel planes. Nathalie Tocci tells the story of this dynamic triangular relationship, exploring how and why the US has shaped the course of relations among its allies. An empirical study with strong policy relevance, this volume draws on in-depth interviews and official documents to provide a succinct overview of the issues and stakeholders. Tocci argues that the Turkish situation can be viewed as a quintessential case study, tackling broader questions about US foreign policy in the region as a whole. Nathalie Tocc i is Deputy Director of the Istituto Affari Internazionali in Rome, Italy and author or editor of many books, including The EU and Conflict Resolution: Promoting Peace in the Backyard.
