Since 2005, NORAD has already adjusted to Canada's position on ballistic missile defence. The information is already going to the ballistic missile defence organization, and Canada is just not involved in that aspect of ballistic missile defence that would release the interceptors. As long as the Americans are happy to co-operate on this basis, and they simply are, I think it could go on, unless there is some sort of change in the American unified command plan that would move aerospace defence somewhere else or change the nature of USNORTHCOM, but they have just gone through a review of the Goldwater-Nichols arrangements, and I don't see that happening.
As for Canada's participation—certainly it would not build interceptors of its own and deploy them—it could mean a financial contribution to the American program, or it could mean having Canadians directly involved at some of the sites in Alaska. If new sites are put up, on the U.S. east coast in particular, you could have Canadian presence there, just as you have Canadian exchange officers at various commands in the United States. You have Canadians operating at some of the U.S. air defence bases. It would not involve Canada [Technical difficulty—Editor].
