I can start.
I would totally agree with that. I think what Dr. Charron was talking about was part of the evolution of North American defence and modernization efforts that are happening with NORAD. The imperative is on us to work very closely with the Americans. We provide a small portion of the defence of North America. Some of that has been, in the past, strategically important in the Canadian Arctic. What I'm trying to lay out is that I think the importance of that has returned in a way that had, perhaps, gone away for a period of time. Certainly all of the modernization efforts to counter Russian activity and, potentially, Chinese activity we'd have to take in close co-operation with the United States. In the past, almost all of the facilities that were actually built in Canada were built under a joint funding model whereby the Americans paid the majority share. I'm not totally confident that, during the current administration down south, that potential deal would be on offer. If that's the case, then there will be a significantly larger tab for Canada to pick up in doing some of this.
Fundamentally, we can't defend Canada alone. We have to do it with the United States, so we have to take the American position on all of this very seriously, even if we don't agree fundamentally with everything. That's why, I think, one of the strongest things that we need to do with a lot of these measures in the new defence policy is to make sure that Canada maintains full interoperability with the United States government with everything that it's doing, because we can't do anything on our own.
