As dignitaries gathered on the White House South Lawn on Tuesday to witness the signing of U.S.-brokered deals between Israel and two Gulf Arab states, the situation thousands of miles away on Israel's doorstep was less serene.

Speaking from a White House balcony, Trump declared the deals "the dawn of a new Middle East" and said at least five or six other Arab states were set to join the "Abraham Accords.".

But though Trump described the agreements as peace deals, the reaction from Palestinians was a stark reminder that the agreements are not seen as such by many in the region.

"The real peace that is needed, the one that is actually worth celebrating, is if there's something that can be achieved between the Israelis and Palestinians," he said.

"I'm not surprised that the Palestinian terrorists fired at Israel precisely during this historic ceremony," Netanyahu said after the ceremony.

Speaking to Fox News hours before the signing ceremony, Trump predicted the Palestinians would eventually forge peace with Israel or else be "left out in the cold.".

"This illusion that Netanyahu has about making peace with the Arabs without making peace with the Palestinians or withdrawing from the occupied territories is just that — an illusion.".

Emirati Foreign Minister Sheikh Abdullah bin Zayed al-Nahyan thanked Netanyahu for "halting the annexation" of West Bank land claimed by the Palestinians, in exchange for Emirati recognition.

He said the deals Israel had already made with Jordan and Egypt hadn't led to tangible exchanges, tourism or meaningful free movement of people or businesses.

Inbar also said the deals showed that Palestinians had been "obviously sidelined" by Arab states and warned that their ambitions may be unrealistic

It is the latest indicator of a shift in Arab politics from being defined against Israel to being defined against Iran," said Simon Mabon, a professor at Lancaster University in England
