Abbas is complaining that that things have not progressed sufficiently for his liking. Well, genius, that's why there are talks. You talk and negotiate and you work things out and then things progress sufficiently. It seems like every time a positive step forward, like these pre-negotiations, one side or the other throws certain conditions in the way to stifle progress. If they can't have a meeting of the minds they should be pressured to submit the entire dispute to Binding Arbitration. Each side picks an arbitrator; the two arbitrators pick a third arbitrator; the two sides argue their cases in front of the three arbitrators; the arbitrators render a decision; majority decision rules. Compensation should be paid by the United Nations to those who lost property when the UN created Israel. No right of return (except if the land vacated by it's owner is still vacant, then that owner or heirs can return). End of dispute. We're all sick of this. Go lead a normal life.
