correct me if I'm wrong -
about 195,000 American soldiers died fighting against Germans
about 105,000 American soldiers died fighting against Japaneses
I'm not sure how those figures were derived.
Anyway, that's not relevant to the reason why the nuke bombs weren't used on Germany.
why nuke Japan and not Germany?
Germany surrendered before it was necessary to threaten them with nukes. Germany surrendered in May 1945, and the first test of a nuclear bomb wasn't until July 1945. The Germans surrendered before the bombs were even ready.
Japan could have surrendered after the conventional carpet bombing but they didn't. They could have surrendered after the first nuke bomb but they didn't.
The Allies didn't want to be bogged down in a long guerrilla type war on the ground in Japan, where they would suffer many more casualties. Their experience from previous island fighting showed what they might expect to confront.
let's face it. The Caucasians thought poorly of Asian people. The past 3 consecutive wars were Asian conflicts - WW2 (Japan), Korean War, and Vietnam War. It was handled poorly.
How did Japanese troops treat Allied troops that they captured?
How did Japanese troops treat Chinese military and civilians (especially in Nanking)?
Which country attacked America's territory and people?
Is there any wonder that Americans might have "thought poorly" of Japan?
But that's not the reason it was nuked and Germany was not.
The decision by Truman was tactical, not emotional or personal.
The Korean and Vietnam wars came
after WWII, so that's not relevant.
