ERBIL, Kurdistan Region of Iraq – US President Donald Trump on Tuesday said that he wants to “make a deal” with Iran over the nuclear issue, threatening “massive maximum pressure” if Tehran declines.

US President Donald Trump arrived in Saudi Arabia’s capita Riyadh on Tuesday morning, embarking on a regional tour that will also see him travel to the United Arab Emirates (UAE) and Qatar.

Deliver a speech at the Saudi-US Investment Forum, Trump said that he is willing to “end past conflicts,” and wants to offer the Iranian leadership “a new path and a much better path toward a far better and more hopeful future.”

“I want to make a deal with Iran. If I can make a deal with Iran I’d be very happy,” said the American president, “but if Iran’s leadership rejects this olive branch and continues to attack their neighbors then we will have no choice but to inflict massive maximum pressure, drive Iranian oil exports to zero like I did before.”

Tehran and Washington have been negotiating around a solution to Iran’s nuclear program and have held four indirect meetings with Oman acting as a mediator, with the latest meeting held on Sunday. The talks have progressed positively thus far according to both sides’ accounts of the talks.

Trump reiterated his country’s unwavering position that a nuclear-armed Iran constitutes a red line for Washington, noting that they will “take all action required to stop the [Iranian] regime from ever having a nuclear weapon.”

“Iran will never have a nuclear weapon.”

Washington and Western powers have sought robust assurances that Iran is not pursuing nuclear weapons, while Tehran maintains that its nuclear program is solely for peaceful purposes and that it has no plans to develop nuclear weapons. Iranian Foreign Minister Abbas Araghchi has stressed that the issue of nuclear enrichment is “non-negotiable” for Iran.

Trump, during his first term in 2018, walked away from a landmark nuclear deal with Iran, which was introduced three years earlier in 2015 by his predecessor Barack Obama. Known as the Joint Comprehensive Plan of Action (JCPOA), the deal provided sanctions relief to Iran in exchange for the placement of curbs on Iran’s nuclear program.
