The problem with that is, Japan was willing to fight on after the first bomb. They tried labelling it a natural disaster at first; if the second bomb wasn’t dropped, they probably wouldn’t have surrendered. Sure they could have waited longer to confirm that, but then there’s more troops dying on both sides while they wait - more unnecessary deaths.
