Obfuscation can include omission as well as commission. You present only one side of the story. Such as the statements of generals, several of which played no direct role in the Pacific War. One of those who did, MacArthur, objected not so much to the bomb per se as to the refusal to ensure the survival of Hirohito.
Perhaps you should have quoted General Marshall:
“There is one point that was missed, and that, frankly, we missed in making our plans. That was the effect the bomb would have in so shocking the Japanese that they could surrender without losing face. ...we didn’t realize its value to give the Japanese such a shock that they could surrender without complete loss of face.” (David E. Lilienthal, The Journals of David E. Lilienthal, Volume Two: The Atomic Energy Years, 1945-1950, pg. 198).
My mother was a Japanese citizen during WWII. She was in junior high school. She told us that up until the day the Emperor surrendered she and school children, regardless of age, were drilling with sharpened bamboo sticks to attack and kill American paratroopers.
She feels the atomic bomb was justified and saved millions of lives, Japanese and American.
She also is General MacArthur’s number one admirer. General MacArthur had staff officers who studied Japan and through their knowledge respected Japanese culture. That is why Kyoto did not receive the fate that was accorded to Dresden.
MacArthur was also instrumental in moving them to a form of governing that was westernized, including giving the vote to women.
My mother said that he kept sending the politicians and statesmen writing their new constitution back until they got it right.
Heroes and generals all put their pants on one leg at a time, they are mere men after all. But some stand taller. General MacArthur and Truman, in my book, stand tall.
