How do you reconcile that with the commonly held historical view? Or is that merely your own personal opinion?

"Hiroshima was a city of both industrial and military significance. Hiroshima was the headquarters of the 2nd General Army 第2総軍 (日本軍) with responsibility for most of western Japan including Kyushu as well as a depot and port of embarkation in the middle of an urban industrial area. It was a good radar target and it was such a size that a large part of the city could be extensively damaged. There are adjacent hills that were likely to produce a focusing effect that would considerably increase the blast damage. Due to rivers, it was not a good incendiary target. It was classified as an AA(Prime)Target. It had a military garrison of about 40,000 men. Hiroshima was the primary target for the August 6 attack, with Kokura and Nagasaki as alternatives. Far from being an innocent city full of civilians, the garrison of 40,000 soldiers were doing calisthenics when the bomb exploded and were in fact the largest single group of casualties in the city.

Nagasaki was a major industrial city making torpedoes and ammunition. Mitsubishi Steel, Orikami Ordinance Works and a large engine works dominated the production in the city in addition of a large garrison. There were also a major dockyard used for the transport of men and materials to the north. It, too, was a high priority target but was a secondary target that was only hit if the primary target was too cloud covered for a visual drop on the primary."
