Abbas knows what we all know, the report would have to include hamas rockets, Shalit, and the general animosity towards hamas by Abbas and the PA. I doubt that he wants the internal rift between hamas and the PA any kind of headline news. If he stays out Israel gets the heat-although not from the US or even the EU in this case. Not much to be gained by trying to exploit the Goldstone report. In the US the report is something of a joke, not much there either.
