I doubt the US would actually staged an invasion when the US could’ve just kept on fire bombing japan until they surrender. By that time, Japan’s navy was in shambles, their airforce depleted and litterally suiciding pilots as a last ditch effort.
But the pressure to nuke them was to simply end the war fast and prevent russia from laying claims on japan’s mainland.

It’s impossible to say really, the war was clearly lost by the time the bombs were dropped.
It’s really down to how stubborn Japan’s leadership was.
