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).
It’s not that war in general is stupid, it’s that the wars America has gotten involved in for a long time now have all been stupid.
Right, they did. But in retrospect, was it actually?
If the US had stayed neutral from the beginning, do we think Japan would have bombed America's military base?
Philip K. Dick's The Man in the High Castle suggests what would have happened if the US did lose the war. Remaining neutral would have been a different result, though.
