@peachfront @preinheimer it takes less than an hour to get from the US border to cities housing 2/3 of the population. There's just no time for evacuation when an invasion has actually started. If you're going to evacuate and keep most of your population from being occupied, it has to happen ahead of time.
@peachfront @preinheimer and, of course, there would have to be military in that area. Just the minimum number of civilians possible.
