Here is a data of The Rape of Berlin, which was happened in the summer of 1945,
Soviet soldiers caught many German women for raping, and massacred so many
German civilians. The pregnancy rate of The Rape of Berlin was 23%.

And then Chinese government has been accusing 20,000 to 80,000 of Chinese women
were raped by Japanese soldiers. As far as I could work it out, at least 4,600
to 18,400 Chinese women should have become pregnant after a set period of time.
Furthermore, the big baby boom should have taken place in Nanking 10 months after
the fall of Nanking.

Have you heard 4.600 of Japanese and Chinese mixed parentage babies were born
in China? No way!

황혁준 If japs all killed raped chinese women, it might be possible. Think so.

+황혁준 According to your story (not history) , every Japanese soldier's duty
might have been to kill each Chinese woman after raping without fail, unlike
Soviet or South Korean soldiers. No way! lol
