Question: Why didn't Superman spin the world (and time) backwards enough to prevent the nuke from exploding in the first place? Wouldn't that have saved a lot more lives?
Answer:Just to clarify: Superman didn't spin the Earth backwards. We just see the world turning backwards when he went back in time. Of course this doesn't answer your question and it shows how difficult it is to write a good time travel story that doesn't leave the audience thinking of better ways to solve problems.
I guess the way they wrote it, Superman got to be the hero and also get the girl, not really too bad of an outcome.
