In my opinion, BMD is the obvious natural NORAD mission that we could perform with the United States. I think it's something we've missed out on. I used the words “abrogated our responsibility” in my presentation. I believe it's something in which we morally have an obligation to participate, and we should. It's the obvious first choice, if you will.
I don't discount the possibility of working with the United States on cyber issues. I recognize the disparity between how they're dealt with in both countries, but I think there is perhaps an opportunity that we could explore, within the context of a NORAD-like undertaking, to share cyber defence issues.
