And maybe that's really the humanitarian failure. That USA didn't nuke China in 1950 or 1951. Would have solved a lot of problems for generations of people.
USA dropping nukes would have prevented the convention against using nukes in wars from being started. I think there's a pretty good chance we wouldn't have any civilization left by now if we went down that fork in history.
Maybe the real humanitarian failure is that the US didn't nuke everybody and start over from the stone age. Can't any societal problems if no societies exist, right?
