I was debating a friend on the morality of the atomic bombs(he had just read 'Hiroshima' in English, and the teacher is a big anti-atomite). He pointed to the lives lost; I pointed to the lives saved.
He then asked why Operation Olympic was even necessary; why we couldn't simply ignore the Japanese, let them get food, etc.
I questioned how letting them stay in such an enviroment was ethically superior, along with a few other things. What would you have said?
The United States War Department had begun planning for possible war with Japan c. 1920, the results of which were a published case study and strategic blueprint entitled “War Plan: Orange.” American government was on the offensive against the Empire by 1935; a string of embargoes and prohibitions were promulgated then or not long after. The Japanese, even when ‘left alone” by the West, were purely expansionistic.
Some ask whether or not “ultimate victory” was preferable. Certainly it was. While I think too much is often made of the Imperial Army High Command and its willingness to fight to the last man, we cannot but recognize that giving the Japanese a chance to “get back on their feet” would have been fruitless. By August 1945, the war had expanded to include the Soviet Union. Without an atomic bomb to end the war decisively, the Soviets looked ready to island-hop themselves over to Hokkaido. It would have meant a joint occupation of the Home Islands with a distinctly Korean or German flavor. American national-security prohibited such allowances.
Your friend asks the argument, “Why war?” by extension. It’s akin to arguing that Pearl Harbor was a military target and war was thus unnecessary because national survival was not visibly at stake. Had we let Japan “off the hook,” they’d have been gobbled up by the Soviet advance – not to mention made ready to fight once more within a few years’ time unless the same crippling embargoes were imposed. Remember Germany and their ability to “sanction skip” after Chamberlain.
I have heard the stories and personally I wouldn't be terribly troubled with ending the Japanese culture.
That's your point of view. Keep in mind you are essentially condemning anything save Western culture. I say again: the Japanese are victimized themselves as having lost a war. They are no more - or less - guilty than any other nation or people.
