I think it was when USNORTHCOM and Canada Command were formed and then eventually CEFCOM, which became CJOC, there was clearly an effort to try to protect North America from more than just the aerospace domain. At that point, the question of NORAD was discussed.
Since then, in 2006, the NORAD agreement was renewed forever, in perpetuity, and therefore we have been working in the aerospace domain and with maritime domain from a maritime domain perspective. The practical execution of continental defence now, if you want to call it this, is performed in our domains through NORAD but also performed with a combination of the operational output of NORTHCOM, CJOC, and NORAD. The three commands have tried to recommend staff talks about how we make progress on our agenda now, because we are working very closely together and we are producing joint effects. Let me give you an example, which also illustrates a little of the difficulties.
If you have a submarine approaching North America, that submarine is a problem for the maritime component commander in Canada under CJOC and then for NAVNORTH in the United States, which is their maritime component commander under the command of NORTHCOM. How to address that submarine approaching is done through a joint task force. Bilaterally we join forces, maritime patrol aircraft, surface ships, and so on, and we will pursue the target as it arrives.
As soon as that submarine launches a cruise missile, the cruise missile becomes a NORAD responsibility, which is perfectly in line. For that matter, it's a bit difficult but, ultimately, the point I want to make here is that as we prosecute the submarine bilaterally through a combined joint task force, which is fully under the command of the commander of NORTHCOM who is also the commander of NORAD, at the end of the day, it arrives back in Colorado Springs anyway.
This is how, as we look at the future under tri-command, we are now starting to challenge ourselves with questions such as whether the aerospace domain is sufficient to defend North America or whether we should think about going into a binational as opposed to bilateral approach. That's very important for us. Binational means that we're integrated and Canadians have a say; bilateral means that you arrive at what you have and that very often you're not in the command chain. Is it a better construct to defend North America? This is the advice of commanders now preparing to craft for both chains of command and look to the future, again with the common objective of providing in a NORAD type of construct, so binational, a continental defence perspective. I don't know if a solution is going to come out of it, but this is what we're preparing to craft.
