Alaska is on the front lines of an increasingly hostile US-Russian relationship. With the Arctic Circle melting and shipping lanes opening, things could get ugly fast.

On GZERO World, Ian Bremmer sits down with Alaska Governor Mike Dunleavy. He is clear-eyed about the growing military importance of Alaska as tensions rise in the Arctic, especially with increased Russian and Chinese activity in the region. “Alaska is truly the operational fort for North America,” he tells Bremmer. Dunleavy also calls for more investment in military infrastructure, including icebreaker ships, to secure America's Arctic frontier. “We only have two [icebreakers] in the United States. Because of Alaska's position and what is happening now geopolitically and with a warming Arctic, Alaska should have a minimum of five icebreakers."
