Japanese culture is Japanese culture. It's for them to create and for them to own. Fighting to the death, jumping from cliffs rather than surrender, those are all options the Japanese had and were within their rights to include in their culture. But it cost them two atomic weapon attacks and, had they not revised their culture for the times, would have cost them more.
It has not changed all that much really.
To this day Japan has one of the highest suicide rates in the Industrial world. And unlike in most nations where the suicide rates are highest among teens and young adults, in Japan it is highest in those who are from 20-44. Especially when people lost jobs, a business fails, or a divorce happens. Their sense of failure often leads them to this to atone their shame.
This is a major problem, and in men from 20-44 suicide is the leading cause of death. Even their own government admits this is a problem, and has been trying for years to stop it. And for both sexes from the age of 19-44, suicide is the leading cause of death (in the US suicide ranks at #9, below cancer, heart disease, diabetes, and even pneumonia).
Of course, it is a culture and religion that does not have any prohibition against suicide. And culturally they accept that as the honorable thing to do if you have somehow fallen into dishonor. In fact, one interesting thing about Japan, if you want to take a loan out for a business, the banks generally mandate that the person take "suicide insurance", so that if the person takes a loan and their business fails, the bank is not left holding the bag if they then kill themselves because of it.
This is literally a culture that honors suicide. Plays and movies have been made about how it is the right thing to do, and they honor those who have done it in the past. That was their culture then, it still is to this day. SO why people would think it would be any different, I have no idea.
In 2007, Cabinet Minister Toshikatsu Matsuoka was being investigated for fraud. THe day he was supposed to appear in front of the Diet to answer questions he killed himself. Former Tokyo Governor Shintaro Ishihara even praised that action, saying it was the honorable thing to do and he died like a "true samurai".
So why people refuse to accept that most of the nation would have died fighting against hopeless odds rather than surrender, I have no idea.
But yea, Poopy really does not know Japanese culture. The fact that he can not comprehend the difference between a Pro Quo Ante Bellium armistice and a surrender and insists they are the same thing is a show of his failure.
Yea, what Japan wanted was the same as what it accepted. Well, other than war crime trials, occupation, disarmament, no Government reform, and return of the islands they had lost in the war, and retaining control of Korea, Taiwan, and a lot of other territory. Yea, just tiny things that do not matter at all.
