Where do you get that idea from what I wrote?
The commenting upon the dubious Constitutionality of the Air Force, Space Force, and Army is not the same thing as claiming we do not actually need an Air Force, Space Force, and Army or that having them is "a mistake".
I actually think we need all four... well three, frankly, I'd merge the Space Force and Air Force back together and rename it the Aerospace Force.
But I also would like to see a Constitutional amendment to allow Army procurement and and standup for more than two year timeframes thus updating the Constitution to what is actually needed for a modern military.
