Book excerpt: Tracing the evolution of Turkey's foreign policy, from isolationism to regional agreements and organizations, this study explores the country's new international posture. Rubin (strategic studies, Bar- Ilan University) and Kirisci (political science, Bogazici University) assess Turkey's policy toward Europe, Russia, Central Asia, and the United States, as well as its growing role in the Middle East. They address the issues central to Turkey's economic, energy, and water policy. They also discuss the interest groups and institutions affecting the policymaking process and the challenges facing the country's rapidly urbanizing and industrializing economy.
