Great time for Japan to put all of that fancy tech they have to use for more than weird video games and erotic toys.
Their men can seriously use the work rebuilding their military. I almost dont mind the spate of WW2 movies that they have been producing either if it gets some of their old warrior spirit back. It sure beats Americans having to do the work.
Unfortunately, the Japanese decided to emulate the Germans in their racism and mercilessness in combat against what they considered were inferior.
I think 70 years of American influence when it comes to the Rules of War will prevent them from repeating the atrocities they committed in WW II.
