As US President Donald Trump pushes for a deal with Iran, he is reviving one of the signature foreign policy projects of his first term: the Abraham Accords.The series of agreements, which have normalised diplomatic relations between Israel and five other states, are back in the spotlight after Mr Trump tied negotiations to end the war to more Arab nations signing on."I am mandatorily requesting that all Countries immediately sign the Abraham Accords," Mr Trump wrote in a social media post on Monday, local time."It should start with ... Saudi Arabia and Qatar, and everybody else should follow suit. If they don't, they should not be part of this Deal in that it shows bad intention."The post followed a phone call between Mr Trump and leaders from Saudi Arabia, the United Arab Emirates, Qatar, Pakistan, Türkiye, Egypt, Jordan and Bahrain.But the proposal has already hit resistance, with Pakistan publicly rejecting the idea, while other countries on Mr Trump's call have so far remained silent.Here's what to know about the Abraham Accords and whether other countries will join.What are the Abraham Accords?The Abraham Accords are a series of agreements aimed at normalising ties with Israel.The first agreements were signed at the White House in 2020 between Israel and two Gulf Arab states, Bahrain and the United Arab Emirates (UAE).The deals were brokered by the Trump administration as part of a broader push to integrate Israel more fully into the Middle East.At the centre of the effort was Mr Trump's son-in-law and senior adviser, Jared Kushner, who worked alongside Gulf leaders and Israeli officials to secure the agreements.Senior White House adviser Jared Kushner (right) brokered the initial agreements with Gulf Arab states in 2020.
