If the bombing "losses" are intended or expected, then what is the difference, morally?
Penetrating deep into an enemy’s homeland to destroy targets and being forced to do it from the air, which results in collateral damage, is bad enough, but once you arrive there and then to slaughter them by hand, individually, is an entirely different thing.
I know that our GIs will bomb, and use artillery, but I don’t think that they will go in, root out the families from their homes and put them all to the sword, once we have taken the city.
