Our interest in the international rules-based system has remained constant. How NATO expresses that has shifted over time. During the Cold War, there was a very clear focus on collective defence. With the end of the Cold War, there's been a very clear focus on out-of-area crisis management operations. Now we're back, post-2014, to a world in which we have to do it all at the same time. Coupled with that has been a rise in asymmetric threats of terrorism, for instance, for which NATO has a role to play but it has to work very carefully with its partners. NATO shifted to create over 40 partner states, for a really big network and much deeper relationships with the UN, EU, OSCE, etc.
We're still there in the middle of NATO, but NATO is shifting, and it's kind of in the middle of concentric circles of bodies and states working on international peace and security. It serves Canada's peace and security interests even more in a way.
