Is there any reason why the Constitution shouldn't be amended to authorize one?
I would expect pretty strongly that many Air Force construction projects have appropriations longer than two years. That would be constitutional for the Navy, but not for any other branch of the armed services.
How hard should it have been, before authorizing multi-year appropriations for airplanes and equipment, to pass a Constitutional Amendment specifically saying:
I think it's stupid. The reason the Constitution doesn't authorize an Air Force is because only birds flew then. It doesn't authorize a space agency, either.
What Neil Armstrong did was unconstitutional, dammit, in the Ron Paul world.
JFK's challenge to put a man on the moon before the end of the 60's would have met a serious challenge, and undoubtedly folks of Ron Paul's mindset would have fought the constitutional amendment all the way.
I don't think we needed a constitutional amendment to give Charles Schulz a certificate and shiny piece of metal, either.
