First to understand the question, we're always evolving the threats and the situation in the Arctic, as we are with any part of the world. As the situation unfolds, we adapt. We make recommendations to the Chief of the Defence Staff. If it requires new resources, he takes that information forward as military advice to the government and engages the force developers, which means primarily the services. That situation can evolve.
For the situation we have at hand, the balance between NORAD's mandate.... You've heard General St-Amand testify here, and I understand that you spent a couple of days down in Colorado Springs, so you have a pretty sound understanding of what NORAD does, what its missions are, and what its force posture is toward the protection of the continent.
Within the context, we have the resources we need to exercise surveillance from a CJOC perspective in the north today. There are always challenges in the future, and we need to be postured towards thinking about the future.
