But the Japanese had fought the 1904-1905 war against the Russians and a learned a lot things that West did not, or that the Western Nations had to learn for themselves in 1914-16 (they had learned most of the lessons by 1917).The Japanese missed out on the trench warfare of WWI. This might have clued them in on fighting spirit versus machine guns.
The Western Nations had little to learn from the backwards Russians and the inferior Orientals. 5 months of siege warfare had nothing to teach the Western nations.
