We've already got George Washington's Continental Army holding the air. Now we've got the EPA defending the water and the air!! Why is there do the USN & USAF exist? These bases apear to be covered Trump was right to create Space Force, nobody is defending Space from being developed or invaded. Could probably cut some costs by letting EPA keep protecting the air and water, might need to lock off with Continental Army about boundaries, but the financial savings could fund a remarkable Space Force. Not sure where the Marines fit in, but as no one is doing any threatening Marinading, I think that could now become their own Department. As for the Coastguard, I ,think that they're secure, at least until CBP starts a power grab, but that's a tweet battle for tomorrow.
Marines were the space force of their day. Then of course came the Air Force. All frontiers have gotten their own military treatments. Space being the final frontier according to Kirk deserves a force too. I find it remarkably farsighted from someone who barely seems able to speak coherently.
