US President Barack Obama will be laying out the White House welcome mat for Palestinian and Israeli leaders this week. It is in a bid to re-launch face-to-face peace negotiations.
Trying to breathe life into the stalled talks, Obama is aiming for the prize that has eluded many US presidents before him: a deal to form an independent Palestinian state and end six decades of conflict in one of the world's most volatile regions.
Robert Danin, Mideast Analyst, said, "Well, I think we've gotten a lot wiser over the years and learned from our mistakes. I think this administration realizes it is important to have the rest of the world and the Arab world involved in the process early on - that is why the President invited President Mubarak and King Abdullah to the White House."
Since the Oslo Peace Accords of 1993, mideast peace talks have stopped and started so often even experts don't agree on the exact number.
But beyond the negotiating table mediators will have to face skeptical Israelis and Palestinians, made bitter by years of failed talks.
Robert Danin said, "I think the handling of public expectations is probably one of the biggest challenges both leaders face and indeed I think it is one of the areas both sides have not done very much to prepare for."
Another hurdle facing the negotiations is likely to be the issue of Israeli settlements in the West Bank.
Abbas already threatened to withdraw from talks if a 10-month construction slowdown in Israeli settlements is not extended past its September 26 deadline, while Netanyahu says he will not renew the moratorium.
