1. america intercepted messages from Japan to Russia indicating JAPAN WANTED to SURRENDER.
Does not mean they would have.
2. Japan had already considered surrendering if america would just allow Japan's Emperor to keep his seat on the throne.
america said no, but AFTER bombing Negasaki and Hiroshima, america gave into Japan's request.
America demanded unconditional surrender, concessions made after surrender where on American terms.3. america knew japan would surrender unconditionally when Japan found out that Russia would join the fight. So, america hastened the two bombings BEFORE Japan COULD surrender for an american show of power toward Russia.
Sounds like a conspiracy theory4. if ANY regards towards human life was any factor at all, america could have detonated the first bomb over water as a deterent/warning.
It took two bombs to force Japans surrender5. The second, even more unnecessary, bomb was completely and utterly criminal. All communication was broken in Japan and america gave no time for the Japanese to assess the first bomb's damage before detonating the second.
Japan refused to surrender after the first bomb was dropped.
PS: For what it's worth, my father also served in Japan after the war. His OPINION is that it was criminal and unnecessary also.
Japans invading the United States was criminal and unnecessary as well.
