It discusses the ways regional security orders contribute to stabilization and balance. The chapter addresses the transatlantic region and its political and institutional adaptation to the ongoing systemic transformations. Theoretically, the chapter depicts transatlantic region as a regional security order, which is under the constant adaptation process, based on the interplay between regional institutions, collective identity and power dynamics within the region and affected by external systemic transformations. The chapter overviews the fundamental principles of NATO deterrence that existed during the Cold War and depicts the major changes that emerged right after the end of the bipolar rivalry. It observes the major changes in Alliance doctrine and challenges it faces in the post-2014 security environment. The chapter focuses on the perception of collective defence and deterrence, and how the principles of NATO nuclear and conventional deterrence are changing over the time.
