America simply doesn’t have a big enough military to cover that much territory tho. And you’re talking almost half of the world’s population. America’s greatest ability is it’s logistics. Logistics don’t work very well if you can’t easily access bases all over the world. And people defend their home country much more fiercely than imperialists attack. Look at Ukraine before they were given credit or Western weapons.

And again, were talking about some of our top trading partners. So the economy dies during this hypothetical. It’s not THEIR will to fight that fails, but ours.
