That's a big question.
First of all, the United States is not concerned with Russia. It's concerned with China. That's its number one emerging strategic priority. That's what the real debate in the United States is. It's not the Russian case.
Many of the dots you connect seem to work very nicely unless you're sitting in Moscow. Looking at the pace of events over the last 20 years from Moscow's perspective, they've seen the expansion of NATO to their neighbourhood; they've seen the west start to try to expand into Ukraine, into what they call the “near abroad”; and they've seen the issues of Georgian membership. From Moscow's perspective, all those things are seen as threatening and somewhat aggressive on the part of the west, Canada included.
My view is that our position on Ukraine and the way we've handled that has not helped. I'm not trying to justify Vladimir Putin's policies, but at the end of the day, should we be concerned about the Russians' capabilities relative to the Arctic and their military activities in the Arctic? Yes, we should keep a close eye on them. Whether they're just the natural modernization of military capabilities relative to the interests of the Arctic, which we can explain away—where I lean to right now—rather than having hostile intent, that's a difficult question to answer.
