Abbas is avoiding negotiations because he has no ability make a deal or make peace. It is why there has been so much focus on building up Abbas. He cannot make a deal that does not get ALL of ISRAEL and everything. No Pal politician can. The PLO and Hammas dont and wont recognize Israel. To go back to the Pizza analogy.. you dont share your pizza with someone who demands they have all of it and if they dont get it blow up your pizza. Bibi has said and committed to two states. He has asked for direct talks. Wouldnt direct talks be the quickest way to resolve this. Also the Pals must be willing to compromise a bit. They cannot and should not expect 1967 borders and J'lem. You dont get everything back after three wars. Compromise and you can have a state.
