The Arabs by now know that they would be attending useless peace talks if at some point in the conference (the beginning, middle, end)they didn't recognize Israel's existence. So, if they still insist on continuing, what's Israel got to lose by attending? If the Arabs just use the conference to harangue Israel, Israel can always walk out. Incidentally, I love mideast food, I accept an invitation to the conference.
