Small states are dependent on the economic, political, and societal shelter provided by larger states and international organizations to survive and prosper. This book demonstrates the size-related disadvantages and unique needs of small states in order to evaluate, explain, and predict small state behaviour. 'Deriving a new theory of shelter-seeking behavior from the case of Iceland, this innovative book contributes greatly to our knowledge of how the strategies of small states help shape the spheres of influence of large states. To understand the power of the large and strong we must understand the agility of the small and weak.' - Peter J. Katzenstein, Walter C. Carpenter Jr. Professor of International Studies, Cornell University, USA. 'This book is a must-read for scholars and practitioners interested in small states in international relations. The authors demonstrate conceptually and empirically how smaller states can benefit from bigger state shelters and reflect upon current challenges and opportunities.' - Diana Panke, Professor for Political Science at the University of Freiburg and holder of the chair in Multilevel Governance, Germany. 'Small states depend considerably on what happens beyond their shores. Given this predicament, they leverage protection from the same exogenous environment that threatens their survival and prosperity. By using Iceland to exemplify the use of shelter theory, this book offers powerful insights into the behaviour of small states in the international system.' - Godfrey Baldacchino, Pro-Rector and Professor of Sociology, University of Malta, Malta.
