If I could answer that one, sir, you could give your voice a rest.
I've done two tours with NORAD, so I'm intimately familiar with it, and I was the deputy commander of the Alaskan NORAD region, just to show the bi-nationality of the arrangement. There is nothing in the NORAD agreement, for example, that precludes sovereign action. The joint action is by design in the agreement; however, Canada can act in whatever capacity Canada wants to, as can the U.S. in the exact same circumstances.
To give one more example of that, with Operation Noble Eagle in terms of the directed landing piece and the ability to do shoot-downs, that's a sovereign decision. It's usually in the NORAD architecture to enable sovereign decision-makers to make sovereign decisions.
