Abu Mazen's accomplishments

"Abu Mazen [Mahmoud Abbas] has been playing completely by the book. The PA has been killing Palestinians to prove that he is prepared to serve Israel’s security interests. What did he get in return? Only a continuation of setttlements, home demolitions, land expropriations…" And Abu Amr is rather close to Abu Mazen, or has been. (thanks "Ibn Rushd")
