Well, I would say that it would be pretty obvious that we are marginalized to a degree because we don't participate in North American ballistic missile defence, and when those decisions are taken in NORAD, we have to step back from those decisions and not participate in them.
You have a policy that's different from our key ally in NORAD, so there is going to be a certain element of that. Is this a major obstacle that hinders our operations with NORAD on a daily basis? No, not at all. The NORAD mission is one that we're full participants in. It's just on this one issue of ballistic missile defence that we don't have a voice.
