Iran and the United States held indirect negotiations in Geneva, Switzerland on Thursday over Tehran's nuclear program, but the talks ended without a deal. Oman's Foreign Minister said there had been 'significant progress' but Iran rejected proposals to transfer enriched uranium abroad and insisted on continuing its uranium enrichment. The U.S. has gathered a large military force in the region, raising fears of a potential war between the two countries.

Why it matters

The failure to reach an agreement on Iran's nuclear program leaves open the possibility of U.S. military action, which could spark a wider regional conflict. Iran has threatened to attack U.S. bases and Israel if attacked, potentially drawing the entire Middle East into war. The high stakes and lack of a clear path forward make this a critical juncture in relations between the U.S. and Iran.

The details

The talks in Geneva were the third round since a June 2025 war between Israel and Iran. The U.S. delegation was led by billionaire real estate developer Steve Witkoff, serving as a special Mideast envoy, and Jared Kushner. Iran was represented by Foreign Minister Abbas Araghchi. The two sides held around three hours of indirect negotiations before adjourning, with Iran rejecting proposals to transfer enriched uranium abroad and insisting on continuing its enrichment program. The U.S. is concerned that Iran is rebuilding elements of its nuclear program that were damaged in the 2025 strikes on its facilities.

  • The talks in Geneva took place on Thursday, February 26, 2026.
  • Technical-level talks are scheduled to continue next week in Vienna.

What they’re saying

“There would be no victory for anybody — it would be a devastating war.”

— Abbas Araghchi, Iranian Foreign Minister (India Today)

“There might still not be a breakthrough at the end of this day, but the very fact that the U.S. team is returning shows that there is enough common ground between the two sides.”

— Ali Vaez, Iran expert, International Crisis Group

What’s next

Technical-level talks between Iran and the U.S. are scheduled to continue next week in Vienna, where the International Atomic Energy Agency is headquartered. The IAEA would likely play a critical role in monitoring and verifying any potential nuclear deal.

The takeaway

The failure to reach an agreement on Iran's nuclear program during these high-stakes talks in Geneva leaves the risk of a devastating regional war hanging over the Middle East. Both sides appear to have made some progress, but fundamental differences remain that will require difficult compromises to overcome if a diplomatic solution is to be found.
