I can't really comment on details of specific issues we've dealt with on climate change. Those discussions have not occurred within my office, so I'm not aware of them. They may very well have happened. But on a strategic level, we have had military-to-military discussions, and they are ongoing, on how we are going to cooperate in the north.
The north is a vast territory that's essentially untapped, which means we have a chance to cooperate with the league of arctic nations on how we're going to deal with some of the issues in the north. I think this dialogue will continue as the years progress. We have a chance to get this right.
