Sir, I would say that clearly we care, or I wouldn't be here today. There is a degree of angst, perhaps, associated with submarine movements that is out of proportion to what I would consider the threat they pose to us at the moment. At the end of the day, their effectiveness lies in their ability to remain undetected, and we have for years countered that effectiveness by seeking to detect submarines. Particularly during the Cold War, it was very important to us to know where potentially threatening submarines were and what they were doing. As we moved out of that, we became less concerned with the movement of submarines, except, obviously, our own.
I would say that as we look at changing patterns of activity, it's not a bad idea to be aware of what submarines are doing. We focus on that as an allied community. From my perspective as commander of Canada Command, knowing exactly what submarines are doing up in the Arctic is related far more to our potential responsibility for rescuing them if they get into trouble than to what it is they're doing there and why.
Does that answer your question?
