Thank you very much.
Since NORAD's original agreement in 1957, the threats facing North America have evolved significantly. In your opinion, what sort of regular measures are taken by NORAD, the Canadian Armed Forces, and the U.S. Armed Forces to ensure that NORAD remains a step ahead of any potential threat to the defence of North America?
Because it's such a broad question, I wonder if you could first do a broad response and then narrow it down to dealing with the new threat of terrorism and how NORAD might deal with a North American terrorist activity of any particular...since you mentioned it in your opening remarks. You can use an example or give us a scenario where something might occur.
