* Israelis, Palestinians as far apart as ever on core issues
* Washington looks to prolong talks, acknowledges big divide
* Abbas under pressure to walk away from negotiations
By Crispian Balmer
JERUSALEM, March 15 (Reuters) - With pessimism growing by the day over the future of Middle East peace talks, U.S. President Barack Obama will meet Palestinian President Mahmoud Abbas in Washington on Monday to try to break the stalemate.
The deadline for the negotiations between Israelis and Palestinians, aimed at ending their entrenched conflict, expires next month and Washington is eager to persuade the two sides to prolong their discussions within a new framework.
But expectations of imminent progress are minimal.
After eight months of initial talks, and at least 10 trips to the region, U.S. Secretary of State John Kerry sounded unusually gloomy during a Congressional hearing on March 12, indicating that little progress had been made so far.
"The level of mistrust is as large as any level of mistrust I've ever seen," said Kerry, a veteran of Middle East diplomacy. "Neither (side) believes the other is really serious. Neither believes that ... the other is prepared to make some of the big choices that have to be made here."
However, he said it was still possible to extend the talks. Obama's direct involvement is aimed at providing much needed additional impetus: he saw Israeli Prime Minister Benjamin Netanyahu earlier this month, and is now meeting Abbas.
Israelis and Palestinians have been holding on-off negotiations for more than 20 years with the stated aim of sharing the Holy Land and creating an independent Palestine.
Through all that time, the main, unresolved issues have remained exactly the same -- defining the borders and agreeing on security, the status of Jerusalem and the fate of Palestinian refugees displaced during the 1948 creation of Israel.
Obama told Netanyahu he would seek "difficult decisions" from Abbas and would push him behind closed doors as hard as he did the Israeli premier to help narrow the gap for a framework accord, a senior U.S. official said.
Although the terms of the mooted accord have not been published, Palestinians say early indications suggest they will be offered less than what former U.S. President Bill Clinton laid out in 2000 in the so-called Clinton Parameters.
The president's aides have made clear that Obama wants the framework document to be seen as even-handed, despite the sense among many Palestinians that Washington is favouring Israel.
Besides the so-called core issues, other hurdles to a deal have also emerged, particularly Netanyahu's demand that Abbas recognises Israel as a Jewish State.
Israel says this would show he was serious about ending the conflict, but the Palestinians say it would merely destroy their own narrative. Abbas says accepting it would effectively deny his own people's centuries-old links to the land and would also mean renouncing the right to return for some 5 million Palestinian refugees and their descendants.
Washington has endorsed the Israeli position but, perhaps revealing a frustration with Netanyahu, Kerry told the House Committee on Foreign Affairs on Thursday that it was a "mistake" to raise the issue repeatedly "as the critical decider".
Adamant not to give in on this point, Abbas also faces pressure at home not to agree to any loosely worded accord that would simply prolong negotiations, with no clear end in sight.
The Palestine Liberation Organization (PLO), which is chaired by Abbas, issued a statement this week expressing its "absolute rejection" of any prolongation.
PLO board member Hanan Ashrawi said that without obtaining a freeze on Jewish settlement-building on occupied territories the Palestinians want for their future state, any further discussions would be futile.
"By extending talks even one more year, they will finish the Greater Israel project given the alarming escalation of settlement activity," she said. "If the document is what we have seen (up until now) then it is not even a starting point."
However, one senior Palestinian official, who declined to be named because of the sensitivity of the subject, said he thought there was a good chance that Abbas would agree to continue talks given the pressure building on him from Western governments.
Speaking to political allies in Ramallah earlier this week, Abbas said he had come under huge duress over the past three years, but vowed not to backtrack over the core points.
"I am 79 years old and am not ready to end my life with treason," he said. (Additional reporting by Matt Spetalnick in Washington, Ali Sawafta in Ramallah and Nidal al-Mughrabi in Gaza; Editing by Mark Trevelyan)
