Suppose, Subject A is a Japanese by citizenship, or may be by birth, but not by evolution. Eventually, Subject A relocates to, let’s say to Canada, Qatar or maybe US, Singapore, Australia. Now assume, Subject A always despised original Japan, with some grudges.
After emigrating/immigrating, Subject A starts galvanizing people in Canada, US, Singapore, Australia etc. against Japan; further approach mainstream, extremist organizations around world, in the name of diversity & free will; to drop another metaphorical nuclear weapon on Japan, this time on Tokyo.
