How about we just don’t fight stupid wars? There hasn’t been a real need for a draft in America since the civil war (in the sense that America was not plausibly threatened by the world wars, Korea, Vietnam, etc).
Americans during WWII thought it was a fight for national survival, starting with the shock of Pearl Harbor. Isolationishm turned to intervention in the "Good War." I won't defend any war after that...
Wars are part of nature. It is inevitable. So your proposition is based on wrong assumptions.
