I also said the minimum size of the US military would be zero. Pretty much by definition.
However, that doesn’t mean that we just fire all our servicepeople, sell the equipment off for scrap, and reap the tax benefits. As you say, services that are currently being done by servicepeople would have to be done by in other ways, or not be done at all.
We have to have some sort of a coast guard, even if it isn’t a federal uniformed service. Coastal states could each have a coastal state police force that takes care of interdiction of smugglers and search and rescue. Of course, that would have to be paid for with local tax increases. Back-country search and rescue could be done by state park services, or maybe the federal park service.
But it would probably cost a lot more money to have something like 22 state coast guards than 1 federal coast guard. So scrapping the Coast Guard doesn’t make any financial or practical sense, if we scrapped the Coast Guard we’d pretty quickly be scrambling to outfit thousands of coastal FBI and DEA agents or some such. If we scrapped the navy completely we’d still need a Coast Guard, and probably a beefed up Coast Guard with now that they don’t have the Navy for backup. But that scaled-up Coast Guard then effectively becomes our new, smaller Navy, albeit one with a different mission and philosophy. So if you want absolutely no Navy you have to get rid of the Coast Guard too.
I was just saying, if someone put a gun to my head and said, “Cut the military to the minimum size NOW!”, that we could cut the size to zero, like Costa Rica. That doesn’t mean zero is the optimum size, far from it, even if we imagine the US breaking all our defensive treaties, withdrawing from NATO, bringing home 100% of all our servicepeople, embracing pacifism, and shaking our heads in sorrow when wars and disasters happen in other places around the world, not our business to get involved, wouldn’t be prudent, we will have peace for our time.
But we’d still have to have some method of defending our borders unless we abolished the federal government. You could call those people patrolling the border a federal border patrol police agency, rather than soldiers, and you could call the people patrolling the coast a federal coast patrol police agency, rather than a Navy/Coast Guard. And you could call the people you mobilize for disaster relief an emergency disaster relief police force, rather than the National Guard (which is really 50 State Guards) (Assuming we’re getting rid of the National Guard too).
So yeah, zero. That’s not the number I’d pick if I were in charge, but it’s pretty much the minimum, you know?
