Abbas is such a moderate Palestinian leader, he is practicaly pro-Israeli. If Israel could not find a peace agreement with him, before or after the Hamas election, they will never find a peace agreement. Even now, dialog could lead to results. I think that Israel prefers the status quo and does not care to make any concessions not does it care to give up the current complete control over the Palestinian areas.
