It reinforces the need for greater surveillance capabilities, but I think this was interpreted as simply a symbolic flight, and the date of July 4 was specifically chosen. The assessment is that it's Russia, Mr. Putin, showing Russia is back in the game. After all, NATO has planes flying close to Russian territory, particularly in reaction to events in [Technical difficulty—Editor] and Ukraine, and this is the way he demonstrates the fact he can do to North America, and particularly the United States, what the United States is doing to him.
For me, it highlights the point that because Canada's contributed to augmenting the air defence of allies in the eastern frontier of NATO, we can expect this sort of reaction we got. The need is to track these to be aware of it. Obviously both countries are showing restraint, but it highlights the need for surveillance and greater capabilities.
It's more symbolic, but it's something that can't be ignored.
What the United States and Canada seek to do is let the Russians know that we know they are there, and they can be intercepted. These sorts of probings of North America are part and parcel of what Mr. Putin is doing, and he's doing it to U.S. ships that are coming close to Russian territory as well.
