Yes I know that. Which is why I wrote that. However if you run far enough away from the Japanese that they can't easily get at you, you can't easily get at them. That is a bit different from ducking over a border into a sanctuary. They can't get at you at all but you can still get at them. That is an important thing.

I don't think acknowledging the prime importance of sanctuary is at all misplaced. In the case you cite acknowledging that will lead to realizing that the problem can't be solved unless something is done about the Pak Army/ISI. In China, it helps explain why guerrilla forces didn't accomplish much.

No, according to the book that is not true. The KMT fought quite a lot as proven by casualty figures. The Reds didn't fight so much. Which is the opposite of what we've been told all these years. The Chinese were very upset that the Japanese were around. They just couldn't get them out even though they tried.

Agreed. We don't look at it much because Japanese small wars practices were so savage there is nothing much to be gained by studying them. How much can be gained by going over publications such as "How to kill Filipinos".
