As I said, with regard to ballistic missile defence, our position is that we're not in the North American ballistic missile defence program. Cruise missile defence is separate from ballistic missile defence. There is a capacity for the Canadian Forces to conduct some form of defence against cruise missiles, but I wouldn't want to get into any details on that, based on the security classification that we're operating at.
On the NORAD side with ballistic missile defence, they have an architecture to deal with this. Again if this was something that Canada wanted to officially participate in, I think that would be a key item to consider or talk about in the defence policy review that's about to launch.
