After months of heightened tension following their war in June 2025 and weeks of escalating mutual threats, Iran and the United States resumed fragile nuclear diplomacy on Friday, as negotiators from both sides held critical mediated talks in Muscat, Oman.

Led by Iran’s Foreign Minister Abbas Araghchi and U.S. Special Middle East Envoy Steve Witkoff, the delegations exchanged views indirectly on the key contentious issue of Tehran’s nuclear programme through Omani Foreign Minister Badr Al-Busaidi.

At the core of the dispute between Tehran and Washington lie deep disagreements over Iran’s nuclear enrichment and ballistic missile capabilities, as well as the Islamic Republic’s anti-Israel regional allies.

These major sticking points have pushed the sides into gridlock, with the United States demanding “zero enrichment” and a limitation on Iran’s missile range to 500 kilometres.

Iran has categorically rejected the U.S. conditions, stressing that the right to uranium enrichment under UN verification and its advanced missile programme constitute firm red lines.

Settling dust

This raises the question of what a possible deal between Iran and the United States might look like. Will this new round of talks amount to yet another exercise in agreeing to disagree?

The dust from Friday’s talks is expected to settle within days - if not hours - of them ending.

• Why Iran wants nuclear talks in Oman and what it reveals about Tehran’s negotiating strategy
• Iran deploys ballistic missile at underground base amid U.S. nuclear talks in Oman

For now, the talks appear to have helped avert a military standoff. In the medium term, however, prospects for a major breakthrough remain slim if Iran and the United States are unable to exchange concessions and allow diplomacy a chance to prevail.

The US military build-up in the region and Iran’s unveiling of a new ballistic missile “town” keep the Armada v. Catapulta antinomy alive, reinforcing concerns over a looming showdown that could spill over into a wider regional confrontation.
