Israel and the Palestinians belittled each other's commitment to peace as U.S. envoy George Mitchell began a fresh attempt today to break the deadlock and get them talking to each other again, according to Reuters. In an inauspicuous start to his first shuttle diplomacy visit of 2010 after a dozen fruitless trips last year, Mitchell's arrival was clouded by tough statements from both sides accusing the other of cynicism. Mitchell, as usual, said little and there was no immediate clue as to whether the public rhetoric might mask a more positive atmosphere in closed-door talks, first with Israelis in Jerusalem and then on Friday with the Palestinians in Ramallah. Chief Palestinian negotiator Saeb Erakat said Israeli Prime Minister Benjamin Netanyahu had on Wednesday "imposed further conditions on negotiations and announced Israel's intention to continue its occupation" of the West Bank whatever happens. "Benjamin Netanyahu has said 'No' to a settlement freeze, 'No' to sharing Jerusalem, 'No' to the 1967 borders, 'No' to the rights of Palestinian refugees. Now he wants to retain the Jordan Valley," Erekat said in a statement. He was referring to a comment by Netanyahu that Israel would retain military control around any future Palestinian state that included the West Bank. "We had hoped to hear a clear commitment to negotiations without preconditions. What we got instead was Mr Netanyahu again trying to dictate their terms and preempt their outcome," Erakat said. Addressing the foreign press late on Wednesday, Netanyahu attacked the Palestinian leadership for rejecting U.S. calls to relaunch negotiations suspended for over a year. "The Palestinians have climbed up a tree," he said. "And they like it up there. People bring ladders to them. We bring ladders to them. The higher the ladder, the higher they climb."
