Again, we share our concerns in this area with our allies, our close allies and we work very closely with them. It's not just the United States. We have others. As you pointed out, one of the important components of the protection of this country is our cooperation with the United States. It's NORAD. It's been in effect since, I believe, 1958, and we've had a very strong relationship of cooperation and protecting Canadian airspace from all types of attacks. Again, that threat as you can imagine, has evolved since the late 1950s but, nonetheless, NORAD itself has evolved in that sense of protecting us from all the types of threats that can come onto this continent.
You know something, you made a very good point as well that I wanted to pick up on. This is really a model for anyone in the world to see that kind of level of cooperation, that understanding, that kind of commitment between two countries that exists between the United States and Canada. This has been a great success story. Again, when I'm elsewhere at NATO meetings and these cooperative efforts come up, I'm always reminded of how well it works in North America for our defence and our cooperation with the United States. It's been a great success story.
