I didn't say that Sun Tzu WASN'T chinese. Of course he was. What I DID say was the the skills of information gathering and stealthful reconnoiter personnel have been around since the days of early china and Sun Tzu. Not sure what point you were trying to make there. (maybe I am just a thickie, but I just don't see it) And yes, ninja were chinese YOU GET A COOKIE!!! lol (It is widely accepted that ninja were japanese in origin. if sources are needed then I can requote the previous historians who all assert this to be true)
train how you fight, fight to live.
