Abbas, president of the Palestinian Authority since 2005, said that his meeting demonstrated the seriousness of the US administration "to reach the agreement of the century in the Middle East during this year or in the coming months".
Trump said: "I will definitely dedicate everything within my heart and within my soul to achieve that deal"
In 2000, President Clinton kidnapped then Israeli Prime Minister Ehud Barak and Palestinian leader Yasser Arafat at Camp David for two weeks in an effort to reach a general agreement.
"In the end, all these central themes fit like a mosaic, like a puzzle and you can not separate one piece or another," he said in 2014. "The last pieces may decide to fall into place, or they may fall to the ground , and leave the puzzle unfinished. "
They fell to the ground.
The current administration of the United States has shown an unorthodox approach to the issue, even before this announcement. Trump was lukewarm with the two-state solution, the cornerstone of US policy. UU During years. "The United States would support a two-state solution if both parties agreed," he said on Wednesday.
The policy formulation has been divided between the State Department and the son-in-law of the president, Jared Kushner. Kushner said earlier this month: "It's not conventional equipment," noting that it included bankruptcy and real estate attorneys.
Last weekend, Kushner said of a peace agreement between Israel and the Palestinians: "If we are going to try to create more stability in the region as a whole, you have to solve this problem."
Surely, some will say that the dispute between Israelis and Palestinians can be addressed regardless of where the United States embassy is located.
The short answer is no. So sensitive and emotional is the state of Jerusalem, and especially its Old City, where the sacred places are concentrated, that the successive negotiations have left it aside.
The Palestinians see east of Jerusalem, occupied by Israel in the 1967 war and then annexed, as the capital of their future state. For the vast majority of Israeli Jews (92% in a 2015 survey), Jerusalem is the eternal capital of the Jewish state.
Some Palestinian officials suspect that the White House has a larger agreement in mind, building a coalition between the Gulf monarchies and Israel in a historic readjustment, with Iran as the common enemy and the Palestinians as a late occurrence.
That is an indication of the changing dynamics in the region. Once the Palestinian issue was sacrosanct for the Arab cause and Yasser Arafat its champion.
Now the Palestinian loyalties (and the territory) are divided between the Fatah movement of Arafat and Hamas. So are the broader Arab loyalties: Qatar's support of Hamas and the Muslim Brotherhood is one of the reasons for its confrontation with Saudi Arabia and other Gulf states.
The Arab world, especially Saudi Arabia, Jordan, the United Arab Emirates and Egypt – now has a greater concern: Iranian expansionism in Iraq, Lebanon, Syria and Yemen.
Even so, This sudden decision on Jerusalem has upset and disturbed everyone, from King Salman of Saudi Arabia to King Abdullah of Jordan and President Recep Tayyip Erdogan of Turkey, the kind of allies Washington needs to build support for any peace plan where you can be working.
That's because Jerusalem is seen as more than a problem about Palestinian sovereignty. It's about the Arab identity and the Muslim identity too.
See the movement of the US embassy UU In Israel to Jerusalem as a power for the militancy itself they face. Palestinian Prime Minister Rami Hamdallah says the measure "will fuel the conflict and increase violence throughout the region."
At his September meeting in New York, Mahmoud Abbas turned to President Trump and said: "Mr. President, we are counting on you."
Now the Palestinians have no one to tell. Some say that while President Trump and Prime Minister Netanyahu are in power, that will not change.
