Next year will mark the 70th anniversary of the creation of Israel.
The Palestinian leadership has pledged to work with Trump, hoping his unorthodox approach can lead to progress previously lacking. He expressed willingness to grapple with this long-standing challenge.
He offered no detail and did not specifically mention the two-state solution, long the focus of worldwide efforts and US Middle East diplomacy.
If there remain such doubts, Trump will be unable to win global trust in his foreign policy. Peace can not be achieved in the Middle East by backing autocrats. "So I do think there is a layer of truth here in that solving the "peace dilemma" may give regional actors the ability to advance their relationships with Israel".
Earlier this week, Jewish extremist groups called on supporters to converge on Al-Aqsa complex on Wednesday to mark the 50th anniversary of Israel's occupation of East Jerusalem, which falls today according the Hebrew calendar. There has always been an underlying skepticism of America in the Arab world based primarily on the USA historic support of Israel, concomitant with our antagonism towards the Palestinians. But brand Trump is simple, big picture - not detail.
Before the US president touched down in Israel, however, his coming visit was marred when Secretary of State Rex Tillerson told reporters the USA delegation was heading to "Tel Aviv, home of Judaism".
A second worrisome element is Trump's attempt to stir up antagonism against Iran, a major power in the region.
Saudi Arabia doesn't recognize Israel's right to exist but the two countries are united in wanting to stop Iran's ascent in the region.
He provided no further details, but touted "unprecedented" intelligence cooperation with Washington.
PRESIDENT DONALD TRUMP: So many young, beautiful, innocent people living and enjoying their lives, murdered by evil losers. It is important to mention that former president Barack Obama had done the same, in selling weapons to Saudi Arabia, which were used in the war in Yemen.
At the same time, he urged Israel to hold back on settlement building in the West Bank, a longstanding concern of Palestinians and much of the world. Saudi Arabia, Jordan, the UAE, Egypt, Oman, and 45 other key Arab nations- are once again prepared to partner with the US on our shared interests.
In what has been interpreted as a swipe at PA incitement, Trump insisted, "Peace can never take root in an environment where violence is tolerated, funded and even rewarded".
