No one loses more than the Palestinians if US Secretary of State John Kerry's efforts to restart peace talks fail, the PLO's top negotiator said Tuesday. "The failure of Kerry's peace plan is not an option. Everyone who believes in two states should help Kerry to succeed," Saeb Erekat told reporters in the West Bank a day after Kerry issued a stark warning to Israel and the Palestinians to resume long-stalled talks. If efforts fail now, Kerry said Monday, they might not get another chance. "We are running out of time. If we do not succeed now we may not get another chance," Kerry told a forum held by the American Jewish Community, amid reports that he is planning to return to the Middle East region soon as he pursues a bid to kickstart the negotiations.
