Israeli Prime Minister Benjamin Netanyahu said the normalization deals his country was signing with the United Arab Emirates and Bahrain could "end the Arab-Israeli conflict once and for all," at a signing at the White House on Tuesday.
"This day is a pivot of history, it heralds a new dawn of peace," he told reporters. "Long after the pandemic has gone, the peace we make today will endure."
He said he hoped the move would one day expand to include other Arab states.
Addressing the gathering, UAE Foreign Minister Abdullah bin Zayed Al-Nahyan personally thanked Netanyahu for "choosing peace and for halting the annexation of Palestinian territories."
"We're here this afternoon to change the course of history,'' Trump told hundreds of people gathered on the White House's South Lawn. "After decades of division and conflict, we mark the dawn of a new Middle East.''
But some analysts have said that the actual achievements of the deal are modest, on the grounds that they merely formalize ties between the nations that had been thawing anyway, and that all three share an interest in opposing Iran's influence in the region.
Meanwhile, as the accords were being signed, rockets were fired into southern Israel from the Hamas-controlled Gaza Strip. Two people were slightly wounded. Israel subsequently carried out airstrikes in Gaza on Wednesday morning.
The agreements do not directly address the decades-long Israeli-Palestinian conflict, though Israel has pledged to freeze its plans to annex the West Bank.
Palestinian authorities have rejected the deals as a stab in the back delivered by fellow Arabs. Palestinian President Mahmoud Abbas said in a statement on Tuesday that the agreements will not lead to regional peace.
"Peace, security and stability will not be achieved in the region until the Israeli occupation ends," he said. "The main problem is not between the countries that signed the agreements and the Israeli occupation authority, but with the Palestinian people who are suffering under occupation."
Saudi Arabia issued a statement supporting the Palestinian position, saying that "the kingdom stands by the Palestinian people and supports all efforts aimed at reaching a just and comprehensive solution to the Palestinian issue that enables the Palestinian people to establish their independent Palestinian state on the 1967 borders, with East Jerusalem as its capital, in accordance with international legitimacy decisions and the Arab Peace Initiative."
Iran and Turkey have both condemned the agreements, which could signal major shift in the region, particularly if Saudi Arabia and other Arab countries normalize relations with Israel.
Trump's supporters hope that the deal will burnish his image in election season.
Speaker of the House Nancy Pelosi, a Democrat, said US lawmakers called for more details on what the agreements actually entailed.
