I’m well aware. I do not interpret the taxing clause to imply such a spending power. In a previous thread, I was explicit that I do not think such programs now justified by the spending power are constitutional (I mentioned New Deal and Great Society).
Probably for that reason, I did not even consider whether the spending power could justify the USAF independently. Now that you have mentioned it, if I thought the spending power was the right interpretation of the taxing clause (which I don’t), I would agree that the USAF is constitutional.
