I agree with TA on this one, at no time would I ever consider the Japanese able to defeat the United States in a prolonged conflict.

Small arms and tanks were all but inferior by the time Japan faced the US and failed to improve them. Leadership was also questionable ( on the ground ). There tactics on the other hand were not. They were the true human wave assault.....

Bonsai!
