Getting Saudi Arabia to join would be a monumental diplomatic achievement. Trump said the agreement "will be approved, but is totally subject to Saudi Arabia joining the very respected and successful Abraham Accords." Netanyahu's office in a statement applauded the prospect of Saudi Arabia joining the accords as a "historic leap forward for peace in the Middle East." The new nuclear deal is expected to last 30 years and involve U.S. firms in the program's development. Then on Thursday, Trump abruptly announced that the deal is contingent on the Saudis joining the accords.
