I have a minute and a half left.
I want to go back to the defence, as well as the offence. We know that traditionally NORAD, as it is in the U.S., is focusing on higher-altitude planes or missiles. There are some new developments around hypersonics by other states. Where do you think NORAD has to enhance, from an offence and defence...? Should it look at increasing the scope of including land or sea into this consideration?
