No, I think it was a politically motivated decision not to participate in missile defence. As a result of that, the United States put missile defence outside of NORAD. We participate in NORAD as an equal. It's a very successful program. The vice-chair of NORAD is a Canadian, and Canada was involved right at the top level during 9-11.
Canada has played a major and appreciated role in NORAD. Missile defence is something we need to look at. It would have been part of NORAD, obviously, if we had joined. We didn't, so the U.S. treats it in another building down the street that we don't have a key to.
