I'd like to return to the question of the Arctic, but on a slightly different dimension.
Mr. Chisu articulated the threat from the Russians, but there's also the issue of sovereignty over the Arctic with the Northwest Passage. As was mentioned by Professor Doran, if there's a whole lot of oil there, there will undoubtedly be more ships wanting to come in and out, so there will be potential conflict over that and certainly potential damage to the environment.
I know that Canada's sovereignty claims in the Arctic are not agreed to by the United States, or the European Union, or Russia, or just about any other country in the world except Canada. I understand that ultimately there may be some international judicial process to resolve it, but I don't know when and I don't know if other countries would even accept that.
My question is for one or both of you. How do you see this thing playing out? With Russia playing a more major role, with oil possibly on the horizon, with global warming opening up shipping faster than had been thought, the stakes may be higher sooner than we might have thought. Do you think there's some scope for a Canada-U.S. deal or compromise in terms of a joint view on the sovereignty question so that we, as you were saying, can work more closely together rather than against each other? More generally, how do you see this playing itself out?
