I don’t have a strong object-level opinion, but I note that it’s possible that some of the bombing of cities in WW2 was (or should be considered) a war crime, and some wasn’t (or shouldn’t be). It might be more helpful to think about specific (possibly hypothetical) bombing of specific (possibly hypothetical) cities, than about the general category “bombing of cities in WW2”.
