Final Warning: U.S. Tells Iran Nuclear Talks Must Deliver Or End

The United States has issued a stern warning ahead of high-stakes nuclear talks with Iran, set for Sunday: show real progress — or it’s over.

U.S. Special Envoy Steve Witkoff made it clear that the upcoming discussions in Oman must be productive, or Washington will be forced to "take a different route."

"If these talks aren’t productive, they won’t continue," Witkoff said, underscoring the growing urgency. He revealed that previous talks were postponed to first secure key understandings with Iran, aiming to make future negotiations more meaningful.

"Hopefully, Sunday will be different. Hopefully, it will lead to continued dialogue," Witkoff added.

According to sources familiar with the planning, the talks will involve only senior-level officials — no technical negotiating teams, which typically handle complex issues like sanctions relief. Discussions will include both direct and indirect exchanges, a source confirmed.

This time, the U.S. is spelling out its expectations with unusual clarity. Witkoff laid down Washington’s red line:

"An enrichment program can never exist in Iran again — ever. That’s non-negotiable. No enrichment, no weaponization. Natanz, Fordow, and Isfahan — their three enrichment facilities — must be dismantled."

Iran, however, remains defiant about its nuclear rights.

"Iran has every right to possess the full nuclear fuel cycle," Foreign Minister Abbas Araghchi posted on X last week. Araghchi is expected to meet with Witkoff during Sunday's talks.

Witkoff hinted that the U.S. might offer incentives if Iran complies with nuclear demands, drawing comparisons to American diplomacy with Russia.

"We’re inviting Iran to join the league of nations," he said. "We’re telling Iran: you can be a better nation. We can do business together. We can have strategic partnerships. But you can't continue as a provocateur."

He also acknowledged that Iran continues to insist it does not seek nuclear weapons — a position Tehran has consistently maintained for years.

Importantly, Witkoff stressed that the upcoming talks will focus solely on Iran’s nuclear program, not its broader regional activities.

"Do we believe Iran must stop enabling Hamas, Hezbollah, and the Houthis? Absolutely. But that’s a secondary conversation," Witkoff said. "The nuclear issue is existential. It must be resolved — and resolved quickly."
