WASHINGTON (AFP/Reuters) - US efforts to revive the Middle East process floundered Tuesday after President Barack Obama and Israeli Prime Minister Benjamin Netanyahu held closed-door talks amid signs of friction. The two went into talks with the United States having renewed its opposition to Israeli settlements in the West Bank. Netanyahu left the White House after spending an hour and 40 minutes, without making the customary public appearance with the US president. The President reaffirmed our strong commitment to Israels security, and discussed security cooperation on a range of issues, the White House said in a brief statement. The President and Prime Minister also discussed Iran and how to move forward on Middle East peace. Israels ties with the Obama administration have become strained over Netanyahus rejection of demands for a full settlement freeze in the West Bank ahead of peace talks. Aides to Palestinian President Mahmud Abbas said he could quit, leading to a potential collapse of the Palestinian Authority, if US efforts to relaunch Middle East peace talks stay deadlocked, threatening the viability of the Palestinian Authority. President Abbas is not playing games and he is not going to hold on to the presidency just for the title, Palestinian chief negotiator Saeb Erakat told AFP. If President Abbas feels that his project of establishing a Palestinian state is in danger and that Israel wants to destroy the idea of a Palestinian state, then I think he will not remain in the position of the presidency. If there is not going to be a Palestinian state, then there is not going to be a Palestinian Authority, Erakat said. France fears that Israel no longer wants a Middle East peace deal, French Foreign Minister Bernard Kouchner said on Tuesday, and that Paris remained deeply opposed to Jewish settlement building in the West Bank. Later, French President Nicolas Sarkozy expressed his support for Palestinian President Mahmoud Abbas, who has said he does not want to run for re-election in January. The two leaders spoke on the phone ahead of Israeli Prime Minister Benjamin Netanyahus visit to Paris on Wednesday. While Sarkozy encouraged Abbas to pursue Israeli-Palestinian peace talks, Kouchner made clear he was not expecting any swift breakthrough in the negotiations. What really hurts me, and this shocks us, is that before there used to be a great peace movement in Israel. There was a left that made itself heard and a real desire for peace, Kouchner said on France Inter radio. It seems to me, and I hope that I am completely wrong, that this desire has completely vanished, as though people no longer believe in it, he added. In a statement issued on Tuesday, Sarkozys office said he wanted Abbas to continue his work. Senior Fatah official Mohammed Dahlan said on Tuesday establishing the borders of a Palestinian state could resolve the dispute over settlements and allow peace talks to resume He told AFP in an exclusive interview that setting borders could salvage a two-state solution amid failed US-led peace efforts that could otherwise lead to the collapse of the Palestinian Authority. We want to carry out serious negotiations for a two-state solution with a clear timetable not exceeding two years, Dahlan, the former head of Gaza security forces, said in his office in a heavily guarded building in Ramallah. But before that we need the international community to announce an agreement on the borders of the two states... That would solve the problem of settlements and the problem of Jerusalem. We cannot continue talking about the two-state solution as though it is a slogan. We need to transform this slogan into a political decision from international institutions, he said.
