War is an inherently unethical pursuit. Even a “just” war involves death on a massive scale. Even if you believe that some people should be killed, the too politely named “collateral damage” kills innocents. But at least in war each side puts its youth at risk. Anyone on a battlefield can die at any minute. The hope has always been that this crushing reality will make political leaders pause for at least a moment before sending their troops out to kill other people.
