There are no longer any canonical military threats around the Baltic Rim. The previous, divisive order has come to and end but there are yet a number of problems left both in terms of traditional security policies as well as threats that flow from uncertainty and the embrace of the unpredicatable. This book focuses on the prospects of arms control and security networking. Some of the contributions are actor-specifik, some deal with particular issue-areas and the remaining ones take up more principal questions such as the relevance of arms control in the post-Cold War situation and the relationship between arms control and regionalisation. They are unified by the aim of looking upon the challenges with fresh eyes and the singling out of approaches that are in tune with the needs of the Baltic Sea region.
