An American diplomat is quoted in today's Yediot Ahronot as saying that the difference between Benjamin Netanyahu and Mahmoud Abbas is that the Israeli prime minister wants negotiations without a solution to the conflict, while the Palestinian president wants a solution without negotiations. Sounds like an accurate assessment to me.
Now we have the negative half of each one of the leaders' wishes: no negotiations and no solution. Isn't that just great? Both leaders are unwilling to copromise. Netanyahu wants talks that will lead nowhere and to no concessions on Israel's part. Abbas just wants the world community to adopt the Palestinians' favored solution (all of East Jerusalem, including the Wailing Wall, as Palestine's capital; return exactly to the 1967 borders; and the right of return for Palestinian refugees) and to impose it on Israel.
With leaders like these, things will go downhill very quickly.
