It's very difficult to cost-estimate. The idea that somehow we can go to the United States and say that we want to participate and we can assign personnel and NORAD will get a window into the U.S. missile defence systems and get access to more planning, to intercept strategies, etc., I think is just simply wishful thinking on our part. It's part of what derailed the negotiations that Canada initiated in 2003-04, which was, if we participate, what does it mean?
It seems to me that if we're going to participate, then there would have to be some investments that provide added efficiency or effectiveness for the American system and would drive the United States to consider in fact opening the door and rethinking its current U.S.-only planning structure and process.
Radar? What does a modern tracking-queuing radar cost? I don't know. Interceptors? The current per unit price of an interceptor is $75 million. You can add up how many you want, where you would want to put them, and how this would assist the United States, but it's not free. We missed the free bus 20 years ago when things were different.
