Thank goodness that we dropped a bomb on Hiroshima 73 years ago today to end that war

Well their boss agreed with BQ87 and that's all that matters.

When there was a rebellion of Japanese Army officers attempting to steal the emperor's surrender message, after Nagasaki, one can almost argue a third bomb was needed.

One was in the air, enroute from Los Alamos to the west coast when the surrender was announced.

They had three. Mk-III, a Fat Man, was scheduled for Kokura on August 19th
However, it was in San Francisco on 18 August.

There were plans to build one more Little Boy and 12 more Fat Man. They were all going to be dropped before November 1945 before Downfall.

There were 17 target selected. Niigata and Yokohama were the next two after Kokura. Tokyo was not on the list. They needed the leadership to be alive in order to have an unconditional surrender.
