This qualitative study explores the application of deterrence strategies by the United States and Norway in the Arctic. Using the Regional Security Complex Theory to understand complex interactions in the region, the study finds that the countries have differing perspectives and strategies. The US emphasizes global security interests and employs a new concept of integrated deterrence (including integration efforts of allies), focusing on power projection with a punishing nature. Norway adopts a more defensive deterrence by denial, recognizing the link between the Baltic Sea and the Arctic (High North), aiming to avoid significant disruptions through horizontal escalation. These differences in strategies and perspectives can lead to tensions and potential conflicts in strategic agendas. The study also suggests supplementing the theory with transregional security complexes to enhance understanding at the regional level. In conclusion, this research sheds light on the dynamics of deterrence strategies in the Arctic and their implications for regional stability.
