I happen to be a senior mentor for NATO, so I'm in regular contact with NATO.
When I was in NORAD, we would say the Canadian Arctic is Canada-U.S. You have to remember that Canada-U.S. is part of NATO. Now we're going to have seven out of eight countries of the Arctic Circle in NATO. The plans have to make sure that there is no gap or seam between the European portion of the Arctic and the North American portion of the Arctic. A seam and gap provides the potential enemy with a seam and gap to take advantage of because of command and control. There has to be complete coordination between Europe, SOCEUR, and the commander of NORAD to make sure that it's taken care of as a whole.
