Article contentBut thinking about gaps in missile defence and how the United States and Canada can work better together to mitigate the increasing number of missile threats from not just Russia and China, but other countries as well, is obviously a priority. In terms of U.S. interests in the Arctic, I think the main interest is an economic one — preserving U.S. access to key natural resources and to opening sea routes. I think there is concern in the administration about Russian but also Chinese activities in the Arctic, and making sure that those don’t preclude the United States from also operating in the region. Because this hasn’t been a major focus in the past, the United States will have to turn to allies like Canada as well as Northern Europe to operate effectively in that area. So I do think that’s an area of expanding cooperation.
