If Lieberman is upset at Abbas that says that he's doing a very good job. Abbas was a kind of hand picked leader of Pals by the US and Israel. Now, they can not live with him because he is not fully their puppet. Abbas's non-violent actions has put a lot of pressure on Israel and its patron US and they don't like it. Mr. Abbas should then expand this type of actions. Lieberman is a barometer of how a Pals is. The angrier one makes him the better the person is.
