This book takes a comprehensive approach to security in the Nordic-Baltic region, studying how this region is affected by developments in the international system. The advent of the new millennium coincided with the return of the High North to the world stage. A number of factors have contributed to the increased international interest for the northern part of Europe: climate change resulting in ice melting in Greenland and the Arctic, and new resources and shipping routes opening up across the polar basin foremost among them. The world is no longer "unipolar" and not yet "multipolar," but perhaps "post-unipolar", indicating a period of flux and of declining US unipolar hegemony. Drawing together contributions from key thinkers in the field, Northern Security and Global Politics explores how this situation has affected the Nordic-Baltic area by addressing two broad sets of questions. First, it examines what impact declining unipolarity - with a geopolitical shift to Asia, a reduced role for Europe in United States policy, and a more assertive Russia - will have on regional Nordic-Baltic security. Second, it takes a closer look at how the regional actors respond to these changes in their strategic environment. This book will be of much interest to students of Nordic and Baltic politics, international security, foreign policy and IR.
