The report by Ernie Regehr, O.C., Senior Fellow in Arctic Security and Defence at The Simons Foundation Canada, and Kelsey Gallagher, a Researcher with Project Ploughshares, identifies 69 continuously staffed Arctic military sites in the five states with Arctic Ocean coastlines and discusses the challenges of reducing strategic tensions and recovering diplomacy. As Canada’s first northern indigenous Governor General, Mary Simon, has reminded all Arctic states, there is a need “to figure out how [they] can continue working together when a terrible war is going on [which is] contradictory to the rules-based international order.”
