Abbas and the PA are too weak to agree to any deal that would conclusively end a conflict that neither Hamas nor much of Fatah actually wants to end. Recognizing the legitimacy of a Jewish state, no matter where its borders might be drawn, is something that no Palestinian leader can afford to do at this point in history. The culture of Palestinian politics that has revolved around the delegitimization of Israel and Jewish history makes it impossible. That’s why they’ve already rejected three Israelis offers of a Palestinian state including almost all of the West Bank and a share of Jerusalem. So even if Netanyahu were foolish enough to agree to withdrawals that would, in effect, recreate the independent Palestinian terror state that already exists in Gaza in the West Bank, Abbas still can’t say yes.
