Okay. Let me follow up on that, then.
I take your point. I think what we've seen from Russia is, as I think Dr. Charron said, typical. It's not necessarily enhanced now. These are practices that they've done before and that they'll continue to do.
I represent eastern Canada. Even in a territory that is relatively small, resources are limited, whether it's coast guard or navy, and when I look at northern Canada, I see a huge territory. I wasn't speaking so much of jets to be used in terms of any foreign threat. I'm just thinking about what happens up there if there is an incident with a foreign ship coming through, for example. While radar installations and satellites are helpful, so is having the ability to scramble a fighter jet quickly to cover a vast territory very, very quickly.
That's my thinking on it. It wasn't so much the foreign threat that is there, but how are we going to police our own territory?
Dr. Charron, I see that you have returned, so I'll turn things over to you if you have a few comments.
