I think I'll take this first because, of the two witnesses, I'm the international lawyer, although Professor Lackenbauer knows a heck of a lot about international law.
Russia has the same position concerning the legal status of its Arctic straits as Canada has with respect to the legal status of our Northwest Passage. It has the same principal opponent, in terms of the legal claim, in the United States. That's why the dispute is an awkward thing for Canada and the United States to have in the current situation, when we're effectively supporting a belligerent in a war against Russia.
Again, I call for Canada to have open-minded discussions—not negotiations, but open-minded discussions—with the United States on the Northwest Passage.
I will say something else that I think Professor Lackenbauer will support; he's effectively said this. It's that there will be a time when we need to re-engage with Russia—in other words, when Vladimir Putin is gone—and the Arctic is a place where we will be able to start that re-engagement. To the degree that we can avoid an escalation of rhetoric, the so-called security dilemma, that's probably a good thing.
Again, I carry no brief for Russia. Vladimir Putin is a war criminal, and Russia does pose a very significant security threat to North America in terms of nuclear weapons, so let's keep our eye on that ball.
