Can I say just one thing about the Arctic? Let's not securitize the Arctic based on what's happening elsewhere. Let's not apply the lens of Ukraine to the Arctic, because the Arctic is one area where there's been a surprising array of agreement and co-operation between Russia and the United States.
We don't see a military confrontation in the Arctic. That doesn't mean we don't prepare and so on, but I've been working on the Arctic a bit more recently, and there is a great deal more multinational dialogue. The Arctic Council functions very effectively. This is actually an area where we could build goodwill. That's not to view it through a security lens, but to see that this is an area where there is very productive co-operation. For instance, on search and rescue, the Russians, the United States, and Canada work closely together pretty well still, despite what we're seeing elsewhere in the world.
