I wonder what aikido would look like, what it would be called if Japan had won the Pacific War? Or if they had been successful in negotiating a peace with the United States in 1942 as Admiral Yamamoto hoped. Obviously any opinion would be mere speculation, but to me an interesting thought after reading Amdur sensei's book.
There would have been generations of brutality and oppression of Koreans, Chinese, Fillipinos, etc, is pretty much a guarantee. And Russia would have had to do something about having a huge expansive neighbor sharing the Asian continent.
