Yeah, the logistics behind the military were honestly staggering. There was an old joke about how the US military could get a fully operational (built, supplied, and staffed with trained crew) McDonalds anywhere in the planet within 48 hours. Except that it wasn’t really a joke. If the military wanted to, they probably could.
The sheer scale behind the military’s logistics was so vast that people have trouble comprehending it. The same way people have trouble wrapping their mind around how big a billion of something is. Conceptually they may know how big it is, but actually putting it into practice is too large for any one person to truly comprehend. It’s the old “a million seconds is 11 days, a billion seconds is almost 32 years” problem, where the human brain simply isn’t designed to comprehend the sheer scale of something that large in a realistic way. Every comparison we make ends up with people devolving back into concepts in order to keep track of it in their mind.
And we’ve seen all of it begin to unravel in only a few years, because the POTUS has surrounded himself by Yes Men instead of competent leaders. It’s the same way so many despots and dictators have historically been brought low… They surround themselves in Yes Men, and nobody wants to be the one to break the bad news. So the leader is kept blissfully ignorant, while everything crumbles around them. And then they’re shocked when they have angry mobs and/or a coup d’état.
