‘This highly original text makes an important contribution. Well-structured and with clear arguments, it is both authoritative and readable. Strongly recommended.’ -Dr Christopher M. Davidson, Reader in Middle East Politics in the School of Government and International Affairs, Durham University, UK ‘The U.S. security relationship with Europe is an issue of considerable importance for European order. This book provides a cogent analysis of the American commitment to the NATO alliance over the last quarter of a century, from the end of the Cold War to the Ukraine crisis. Yanan Song provides a systematic and thorough study of the wellsprings of U.S. thinking towards NATO and its European allies.’ -Professor Adrian Hyde-Price, Department of Political Science, University of Gothenburg, Sweden This book examines the continuing US commitments to NATO in the post-Cold War era. The initial focus is on the recommitment decisions of the Clinton administration. It also extensively explores the US operations in Kosovo, Afghanistan and, in particular, Libya. The case study on Libya is especially important in exploring the Obama administration’s understanding of the purpose of NATO in the context of current economic pressures, domestic US debates about post-War on Terror interventions, and of increasing American preoccupation with Pacific rather than European security. The author utilises substantial archival research and interviews with policymakers and academics, including Ambassador Kethleen Stephens, former Special Assistant to the President Stephen J. Flanagan, and former Director for Non-proliferation at National Security Council Robert S. Litwak. This book is ideal for postgraduate researchers and academics in US foreign policy, foreign policy decision-making, transatlantic relations and NATO, as well as a great use to undergraduate students. Yanan Song received her PhD from the School of Government and International Affairs at Durham University, UK.
