This is also the largest major reason why America needs to take control of Greenland. If not by owning it, then at least in the way that there is a new deal this week to allow America to do whatever we need to do there. Because the Dome system works by having missile launch sites in many different locations over a wide area, so that they are all overlapping in their maximum range to not leave any blind spots. Canada and Greenland will both be part of this web of launch sites, and the Golden Dome will cover all of America, Canada, and most of the Arctic regions, and probably most of Mexico too. Mexico is not the highest priority because the threats would be from Russia and China, so it is the North, East, and West that need to be covered. There is no civilization in the southern hemisphere that is a threat.
