You're looking at it with the deeply ingrained belief that nuclear bombs are a uniquely horrifying thing, something that should automatically warrant special consideration, and where merely threatening its use was obviously something no enemy could ignore.
The people who made the decisions back then did not have, could not have that belief. They had been fighting a brutal war for years, and it was just a bomb. A bigger, more powerful bomb that they hoped would help win the war, but without the hindsight that informs your view, it would not at all have been obvious to them that this bomb could end the war all by itself. Because a weapon that could force a surrender merely through a demonstration of its power had never before existed.
The point of view you can't find is simply this: "We have to hit them what everything we have, as hard as possible, as quickly as possible, until they can't fight back anymore, because that's the only thing that's worked so far."
