I actually don't know anything about the Scandinavian countries' plans when it comes to missile defence cooperation. I literally know nothing about that, so I can't contribute anything.
I can say more generally that when it comes to defence issues in the Arctic, we have a similar kind of relationship with most of those countries that we have with the United States. There are a few issues where we have diplomatic tensions over specific questions with them, but for the most part we tend to work around that and focus on the things where we can cooperate. There are clearly a number of issues where defence or defence-related cooperation with all of those countries could be expanded from what it is.
Certainly we could have much more cooperation with them in the Arctic context on such things as search and rescue, joint patrols, coordination of surveillance, and showing-the-flag patrols. For sure there's more room there.
