The asymmetry makes the planning largely theoretical: the United States fields more than two million active and reserve personnel against fewer than 200,000 Canadian, and as of 2024 held sixty-five military submarines to Canada’s four. What such preparation would consist of, he did not say. Watch whether Washington responds at all, and whether trade talks resume this autumn.
