That's the million-dollar question, and it refers to understanding the Canadian policy in terms of what participating means for Canada and what we have to do.
Generally in the threat environment today, which is technologically based—in which the United States is integrating air and missile defence, which includes defence against air-breathing bombers and fighter bombers, cruise missiles and hypersonics all integrated with ballistic missile defence into one—Canadian territory starts to become very important. If the United States, for example, proceeds with their third missile defence site in upstate New York, which hasn't proceeded yet, the value of Canadian territory in terms of tracking battle damage assessment radars goes up significantly.
You can imagine that in the future, if this goes ahead, relative to integration, Canada's participation will be welcomed by the United States because we're going to provide a very valuable piece of territory to them for an effective defence of North America.
It also raises the question of whether we're defended right now anyway. We don't know, and that then raises questions about command and control. If you go back to 2003 or 2004, when we discussed this with the United States, the United States said that Canada could not have a role—nor would NORAD have a role—in command and control, but that may all change.
There are a lot of emerging issues in this. My hunch is that down the road, we will have to be engaged one way or another, but how that co-operation with the United States will work out is the million-dollar question.
