Well, my simple view on the Arctic is that it's not a military threat to Canada whatsoever. The thinking that we need to build up armed combat forces to be able to prosecute some sort of naval campaign in the Arctic, with supporting land forces, has a probability of near zero.
For reasons related to my understanding of the climate changes that are going on, it still will be a very harsh environment. You have to look at what the strategic issues there are really going to be about.
There is a security question up there for Canada, one of controlling and maintaining pollution standards and our territorial integrity relative to shipping transportation. We need to do something, and the Canadian Forces can play a role in that, but in terms of devoting specific military resources and developing capabilities to deal with the Arctic, I think that's a very grave mistake that we're making.
As to the threats to Canada, the military threats to Canada, those threats to Canada are almost exclusively in the aerospace world. My view has always been that this is where the emphasis needs to be. If you're looking very narrowly at the threats to the nation per se, in military terms, it's aerospace.
