Iran and the US holding a fifth round of nuclear negotiations in Rome with enrichment a key issue

DUBAI, United Arab Emirates (AP) — Iran and the United States prepared for a fifth round of negotiations over Tehran’s rapidly advancing nuclear program Friday in Rome, with enrichment emerging as the key issue.

U.S. officials from President Donald Trump down insist Iran cannot continue to enrich uranium at all in any deal that could see sanctions lifted on Tehran’s struggling economy. Iran’s Foreign Minister Abbas Araghchi early Friday insisted online that no enrichment would mean “we do NOT have a deal.”

“Figuring out the path to a deal is not rocket science,” Araghchi wrote on the social platform X. “Time to decide.”

The U.S. will be again represented in the talks by Mideast envoy Steve Witkoff and Michael Anton, the State Department’s policy planning director. While authorities haven’t offered a location for the talks, another round in Italy’s capital took place at the Omani Embassy there. Oman’s Foreign Minister Badr al-Busaidi is mediating the negotiations as the sultanate on the Arabian Peninsula has been a trusted interlocutor by both Tehran and Washington in the talks.

Enrichment remains key in negotiations

The talks seek to limit Iran’s nuclear program in exchange for the lifting of some of the crushing economic sanctions the U.S. has imposed on the Islamic Republic, closing in on half a century of enmity.

Trump has repeatedly threatened to unleash airstrikes targeting Iran’s program if a deal isn’t reached. Iranian officials increasingly warn they could pursue a nuclear weapon with their stockpile of uranium enriched to near weapons-grade levels.

Enrichment remains the key point of contention. Witkoff at one point suggested Iran could enrich uranium at 3.67%, then later began saying all Iranian enrichment must stop. That position on the American side has hardened over time.

Asked about the negotiations, State Department spokesperson Tammy Bruce said “we believe that we are going to succeed” in the talks and on Washington’s push for no enrichment.

“The Iranians are at that table, so they also understand what our position is, and they continue to go,” Bruce said Thursday.

One idea floated so far that might allow Iran to stop enrichment in the Islamic Republic but maintain a supply of uranium could be a consortium in the Mideast backed by regional countries and the U.S. However, Iran’s Foreign Ministry has maintained enrichment must continue within the country’s borders and a similar fuel-swap proposal failed to gain traction in negotiations in 2010.

Meanwhile, Israel has threatened to strike Iran’s nuclear facilities on their own if it feels threatened, further complicating tensions in the Mideast already spiked by the Israel-Hamas war in the Gaza Strip.

Araghchi warned Thursday that Iran would take “special measures” to defend its nuclear facilities if Israel continues to threaten them, while also warning the U.S. it would view it as being complicit in any Israeli attack. Authorities allowed a group of Iranian students to form a human chain Thursday at its underground enrichment site at Fordo, an area with incredibly tight security built into a mountain to defend against possible airstrikes.

Talks come as US pressure on Iran increases

Yet despite the tough talk from Iran, the Islamic Republic needs a deal. Its internal politics are inflamed over the mandatory hijab, or headscarf, with women still ignoring the law on the streets of Tehran. Rumors also persist over the government potentially increasing the cost of subsidized gasoline in the country, which has sparked nationwide protests in the past.

Iran’s rial currency plunged to over 1 million to a U.S. dollar in April. The currency has improved with the talks, however, something Tehran hopes will continue as a further collapse in the rial could spark further economic unrest.

Meanwhile, its self-described “Axis of Resistance” sits in tatters after Iran’s regional allies in the region have faced repeated attacks by Israel during its war against Hamas in the Gaza Strip. The collapse of Syrian President Bashar Assad’s government during a rebel advance in December also stripped Iran of a key ally.

The Trump administration also has continued to levy new sanctions on Iran, including this week, which saw the U.S. specifically target any sale of sodium perchlorate to the Islamic Republic. Iran reportedly received that chemical in shipments from China at its Shahid Rajaei port near Bandar Abbas. A major, unexplained explosion there killed dozens and wounded over 1,000 others in April during one round of the talks.
