Mohammed Morsi warns US it needs to change Middle East policy Mr Morsi said the US must honour its treaty with the Palestinian Authority if it expected Cairo to uphold its peace treaty with Israel. "As long as peace and justice are not fulfilled for the Palestinians, then the treaty remains unfulfilled," he said. Mr Morsi's position was warmly received in the West Bank where Nabil Shaath, a senior Palestinian negotiator, said it brought "comfort" to the Palestinians. "[Mr Morsi] doesn't want war with Israel nor does he want to worsen his relationship with the US but he wants both sides to understand that he has his own independent demands of the relationship and they cannot take him for granted," Mr Shaath said. He said it was indisputable Washington had not done enough to help the Palestinians achieve independence. If during the administration of a president like Mr Obama - a man of integrity who is committed to human rights - we can't get much out of the United States, what can we expect from a man like Mitt Romney? Mr Shaath asked. In Jerusalem, Israeli officials declined to respond other than to express hope that Mr Morsi shared Israel's commitment "to the continuation of peace." America's relationship with Egypt, a strategic ally under the leadership of ex-President Hosni Mubarak, has cooled since the Muslim Brotherhood candidate was voted to power. In a recent television interview, President Obama expressed ambivalence, describing the new regime as neither an ally nor an enemy. On September 11, in response to a film ridiculing the prophet Mohammed, protesters scaled the walls of the US embassy in Cairo and tore down the American flag. The incident provoked widespread criticism in Washington, and Mr Morsi defended what some said was a slow response. Before his departure on Sunday, Mr Morsi's official Facebook page posted extracts from a letter from President Obama thanking him for his defence of the embassy. The post added that the president was looking forward to building on their 'strategic partnership'.
