The Japanese did not surrender after the first bomb, and they surrendered too earlier for it to have been the second bomb. They surrendered as soon as Russia declared war.
Japan surrendered when Truman said they could keep the emporer.

Question! Are you saying or making the case for the end of WWII was all because Russia seized the opportunity to be the life savior for the US? My time frame is different than yours as to the Japs surrendering, it was after the second a-bomb was dropped. I was in the Philippines at the time being geared up for the invasion of Japan without any Russian help expected so perhaps I missed a part of history.
