Just on Sunday we commemorated in Canada the Battle of the Atlantic, the longest battle that Canada faced during World War II. Ultimately we had command of the Atlantic fleet, and there were German U-boats that came within the shores of Canada and the United States and sank both navy ships and merchant marine vessels that were trying to deliver goods and services for the war effort. They were going after everything. Newfoundland was part of Britain at that time. Of course, they made a huge contribution as well.
To get to my point, things are changing in the world today. We see what's happening in Ukraine in the context of Russia. In considering threats to North American security, knowing what happened in the past, during World War II, do you have concerns—not only from the standpoint of the Arctic, which you say you see as involving more an environmental than a defence issue—that the aggression that Russia is demonstrating today in eastern Europe could spill over to other regions? I'm wondering what your thoughts are on that.
