Have you ever been near a real war? Your question seems smart and pertinent and I do empathize with it ... and it certainly is humane ... but in the terrible calculus of an real existential war, it does not matter. Horrible, tragic, heart-wrenching, but sadly true that the badly wounded are out of the game and why waste resources on them you may or may not have? Yes, terrible. But reality.
i can tell you’ve never been near the sharp end...
