The answer is twofold. We enjoy the strategic advantage of geography, which constrains the military and defence threats to North America to the aerospace realm. It can be maritime, as a function on maritime launch capabilities, but basically we can focus our attention on that.
The second big strategic advantage we have as a function of geography is that we sit beside the United States. It is a global superpower with the capabilities across the board to lead the global deterrent against not just Russia, but any other threats of importance to Canada that emerge. We benefit, of course, in our relationship with the United States from American support, the provision of American capabilities and American funding support for modernization on a 60% basis for infrastructure in Canada.
All of those work in our favour while at the same time providing us with access to American information and American planning, to ensure that Canadian interests are taken into account in the construct of NORAD as a binational command.
