I believe that the Constitution only applies to (or was only intended to) protections for US citizens.
The Constitution says very little about how wars should be fought.
And the method thereof was to limit the government.
And if the restriction on the government is somehow conditional then isn't it reasonable to assume that the government will do everything it can to throw off those restrictions?
The Constitution says very little about how wars should be fought.
True — that's probably a good thing.
Though IIUC it was the politicians meddling in War that cost us both the Korean and Vietnam Wars.
