Donald Trump has boldly tied negotiations to end his war with Iran to a swathe of Arab nations formally establishing diplomatic ties with Israel.In a 565 word post on his Truth Social platform, the US president made the demand that he was "mandatorily requesting that all Countries immediately sign the Abraham Accords".That is the name he gave to the policy of Arab states normalising relations with Israel during his first term in office.Mr Trump has made no secret of wanting to see some of the region's biggest players establish diplomatic relations with Israel, but little progress towards that has been made.Before the war Saudi Arabia, for example, had refused to consider it unless Israel allowed for a Palestinian state and withdrew from occupied territory.Trump said refusing to normalise relations with Israel would be a sign of "bad intention". (Reuters: Kylie Cooper)Donald Trump's post on Monday showed he was prepared to use the war he launched alongside Israel's Benjamin Netanyahu — which many Arab countries were dragged into when Iran launched retaliatory missile and drone attacks against them — as a catalyst for them joining the movement."It may be possible that one or two have a reason for not doing so, and that will be accepted, but most should be ready, willing, and able to make this Settlement with Iran a far more Historic Event than it would, otherwise, be," he posted."It should start with the immediate signing by 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 the leaders and senior officials from Saudi Arabia, the United Arab Emirates, Qatar, Pakistan, Turkiye, Egypt, Jordan and Bahrain over the weekend, where he talked up the prospect of an agreement to end the war with Iran, now in its third month.US news outlet Axios reported there was "silence" during the call when Donald Trump raised the issue of normalising ties with Israel.Egypt and Jordan have their own peace deals with Israel — signed in 1979 and 1994, respectively — while the UAE and Bahrain joined the Abraham Accords in 2020.Morocco and Sudan joined months later.The US president further claimed Arab leaders would be "honored" to have Iran join the accord too."Wow, now that would be something special!" Mr Trump said."If Iran signs its Agreement with me, as President of the United States of America, it would be an Honor to have them also be part of this unparalleled World Coalition."The Middle East would be United, Powerful, and Economically Strong, like perhaps no other area, anywhere in the World!"Iran said earlier today a peace agreement between the US and Israel was not imminent. (Reuters)The comment is immediately at odds with Tehran's vehement opposition to what it calls the "Zionist regime" in Israel.The Islamic regime's first leader, Ayatollah Ruhollah Khomeini referred to the US and Israel as the "Great Satan" and the "Little Satan."Mr Trump provided no assessment as to why he believed Iran would ever consider such a move.Negotiations 'proceeding nicely'The Truth Social post came as talks between the US and Iran, through mediators Pakistan, continued."Negotiations with the Islamic Republic of Iran are proceeding nicely!" Mr Trump said."It will only be a Great Deal for all or, no Deal at all — Back to the Battlefront and shooting, but bigger and stronger than ever before — And nobody wants that!"On Saturday, he was talking up a looming deal and said it was "largely negotiated" and would be announced soon.Iran has said it will not collect "tolls" in the Strait of Hormuz, but has not ruled out payment from ships using the waterway. (Reuters: Majid Asgaripour)In the hours after, Iranian state media reporting started to chip away at his insistence the Strait of Hormuz would reopen without any restrictions.That prompted Mr Trump to strike a more cautious tone, stating he would not be rushing into a deal.The ABC asked Iran's foreign ministry spokesperson what conditions would be imposed on the reopening of the Strait of Hormuz, including whether tolls would be charged.Mr Trump has hinted an agreement between the US and Iran could soon be announced. (Reuters: Evan Vucci)"We do not collect tolls … in my opinion, one should be careful in the choice of words. we are not looking to collect tolls," Esmaeil Baghaei said."Naturally, in the course of this process, certain services are provided, such as navigational services and the necessary measures to protect the environment of the Strait of Hormuz, the Persian Gulf, and the Sea of Oman."These involve costs that must be collected, they should not be described as tolls or duties."Analysts have questioned whether the war was worth it given issues around the Strait of Hormuz remain unresolved and the deal, as its being reported, would involve an extension of the current ceasefire to allow further talks on the future of Iran's nuclear program.In other words, it would end up with the US and Iran being in a similar position to what they were in before the war began on February 28.Before the talk of the Abraham Accords, Israel was expressing grave concerns about any deal — not only in terms of what it meant for Iran's nuclear ambitions, but also whether it could force it to stop its bombardment of the Iranian-backed militant group Hezbollah in Lebanon.
