Were the bombs of Hiroshima and Nagasaki morally justified?

[The Mikado]

I think there's a plausible scenario where the bombing of Nagasaki is avoided. That said, I can't fault Truman for the way this played out, and the longer the war went on, the more likely a situation where Soviet involvement ends up in giving the USSR more spoils of war in the East becomes likely (The island of Hokkaido becoming The People's Republic of Ezo?).
