Obviously we talk about integrated deterrence. That's the approach that we're using. We always say that integrated deterrence starts abroad, but it also includes more of a whole-of-government effort, because you don't only deter with that national instrument that is the military. You also deter through other avenues as well.
As it relates to the element of the offence in the defence scenario, again, it goes back to my previous answers. This is a policy decision as to whether or not the government wants to change its stance.
What am I going to say, though, is that right now we have an element of defence, which is active defence, because to counter a cruise missile, which is part of our mandate and mission, we have to actually shoot it down. We will engage and defend against a cruise missile, but it's just a different approach from what we have right now for elements like ballistic missile defence. Right now, NORAD has not been tasked to actually defend, i.e.. actively defend, against a hypersonic missile. Our role remains in the threat warning and attack assessment.
