 You would not put in your model the vacation histories of American government officials or like cloud cover, right? You would come up with these very obvious big things like where are the places that have strategic importance or propaganda value? And if you did that, you probably would put Kyoto on top of the list and you get the wrong answer. And you wouldn't get the wrong answer because you're stupid. You get the wrong answer because sometimes things that don't seem to be important actually end up being the most important factor in an outcome.
