Just a Southern view, but I think that both Canada and the US would be well advised to build icebreakers and other equipment for the North. Russia already has done so. No, I'm not trying to stir old Cold War pots! I think that the North is going to change, radically, in the next few decades -- see this, for instance. (By the way, I subscribe to that magazine.)

There are now cruise ships plying the Northwest Passage, and that means change. The permafrost is melting and changing, meaning still more change. The North is changing, and Washington, Ottawa, Oslo, Copenhagen, Helsinki, and other capitols had best awaken.
