There was a good piece on Fresh Air this morning about this. Something that stuck out was how Hiroshima was selected. A commission was created composed of scientists and military personnel among others. Apparently some wanted to drop the bomb on Tokyo Bay while others suggested a remote military instillation to let the world know of it's existence. Anticipating the production of hydrogen bombs many of the scientists wanted to maximize the damage and casualties of the first bomb to "warn" the world of the dangers of these types of weapons.
There was never a reason to wipe out two cities full of civilians and cause truly unimaginable suffering for generations to come.
One bomb could have been dropped over water and had the same effect.
And if it did not have the effect we wanted, THEN we could have escalated.
As it is, we committed mass murder.
I suspect that it also gave us some sort of tacit permission to murder many millions more in the never-ending phony wars we have waged since them.
Hiroshima was both an industrial site and military site....
Atomic bombings of Hiroshima and Nagasaki - Wikipedia the free encyclopedia
At the time of its bombing, Hiroshima was a city of both industrial and military significance. A number of military units were located nearby, the most important of which was the headquarters of
Field Marshal Shunroku Hata's
Second General Army, which commanded the defense of all of southern Japan,
[104] and was located in
Hiroshima Castle. Hata's command consisted of some 400,000 men, most of whom were on Kyushu where an Allied invasion was correctly anticipated.
[105] Also present in Hiroshima were the headquarters of the
59th Army, the
5th Divisionand the
224th Division, a recently formed mobile unit.
[106]The city was defended by five batteries of 7-and-8-centimeter (2.8 and 3.1 in)
anti-aircraft guns of the 3rd Anti-Aircraft Division, including units from the 121st and 122nd Anti-Aircraft Regiments and the 22nd and 45th Separate Anti-Aircraft Battalions. In total, over 40,000 military personnel were stationed in the city.

Hiroshima was a minor supply and logistics base for the Japanese military, but it also had large stockpiles of military supplies.
[108] The city was also a communications center, a key port for shipping and an assembly area for troops.
[73] It was also the second largest city in Japan after Kyoto that was still undamaged by air raids,
[109] due to the fact that it lacked the aircraft manufacturing industry that was the XXI Bomber Command's priority target. On July 3, the Joint Chiefs of Staff placed it off limits to bombers, along with Kokura, Niigata and Kyoto.
