U.S. President Donald Trump hosted the White House ceremony, capping a dramatic month when first the UAE and then Bahrain agreed to reverse decades of ill will without a resolution of Israel's decades-old dispute with the Palestinians.
Speaking from the White House balcony, Trump said: "We're here this afternoon to change the course of history." Flags of the United States, Israel, the UAE and Bahrain were in abundance.
He called it "a major stride in which people of all faiths and backgrounds live together in peace and prosperity" and declared that the three Middle East countries "are going to work together. They are friends."
