That's not something I've understood before.
I wanted you to talk a bit about the new maritime domain awareness issue. With global warming, the opening up of the north, the “northern approaches”, shall we say, I've been told that the real worry is that some ship going up into the north might be able to launch missiles. This brings, in effect, the border much closer to Canadian, and thus North American concerns. Could you speak about that, as to the emergence, if you will, of this possibility?
