• Indirect talks between Iran and the US in Oman on February 6, 2026, focused solely on Iran's nuclear program, with Tehran explicitly ruling out discussions on its missile capabilities during a briefing with a regional diplomat.
  • Hours before the talks, Iran showcased the deployment of its advanced Khorramshahr-4 ballistic missile (2,000 km range) from underground facilities, signaling deterrence amid diplomacy, as tensions flared over agenda, location, and format.
  • The talks, described as a "very good start" by Iran's top diplomat, faced near-collapse due to last-minute changes, heightening fears of escalation in a region still reeling from Iran's missile attacks on Israel in June 2025.

A Diplomatic Start Amid Missile Displays

Iran and the United States engaged in indirect talks in Muscat, Oman, on February 6, 2026, with the agenda narrowly centered on Iran's nuclear program, according to people familiar with the matter. In a briefing to a regional diplomat, Tehran made it clear that its missile capabilities were off the table, a move that underscores the deep-seated impasse between the two nations. Hours prior to the discussions, Iran conducted a high-profile display of its Khorramshahr-4 ballistic missile, launched from underground facilities, a stark reminder of its military posture as diplomatic efforts unfolded.

Efforts to restructure the dialogue have hit a snag, with the US rejecting Iran's demands to exclude missiles from future negotiations, sources indicate. The Trump administration insists on a comprehensive deal covering Iran's nuclear program, ballistic missiles, and proxy support in Iraq, Lebanon, and Yemen, while Iran views missiles as a non-negotiable "red line" for defense. Without a broader agreement, analysts warn that the region could face heightened instability, potentially impacting global energy markets already volatile from Middle East tensions.

Tensions and Regional Mediation

The talks, which shifted from Istanbul to Muscat at the last minute, were described as a "very good start" by Iran's top diplomat, but they nearly collapsed over agenda disputes and format changes. Regional mediators, including Egypt, Turkey, and Qatar, proposed a package where Iran would halt uranium enrichment for three years, export 400kg of highly enriched uranium (HEU), and pledge no first-use of missiles—with Russia offering to take the uranium. However, Iran rejected ending enrichment or exports, maintaining its right to uranium enrichment while denying nuclear weapons intent.

US military presence added to the tensions, with CENTCOM head Adm. Brad Cooper attending the talks, an unusual signal backed by the USS Abraham Lincoln carrier group and jets. This escalation comes in the wake of Iran's missile attacks on Israel in June 2025, which killed 32 people and left Israelis grappling with trauma. As one analyst noted, "The stakes are incredibly high; if these talks fail, we could see a rapid descent into conflict, with Iran's doctrinal shift to an offensive posture raising alarms."

Implications and Future Outlook

Short-term prospects hinge on whether talks can restart narrowly on nuclear issues, such as forming a zero enrichment consortium or arranging HEU handovers, to avert potential strikes. But the missile impasse risks fracturing the dialogue entirely, with the US patience thinning and preparations underway for "real deal" alternatives or military options. In the long-term, experts predict a stalemate could expand to proxy conflicts or collapse into direct confrontation, impacting global oil prices and regional security dynamics.

Attempts to reach out for comments from Iranian officials were unsuccessful, but state media has framed the missile display as a show of strength amid economic strain from sanctions. As the situation develops, stakeholders from Houthis to Hezbollah are watching closely, with debates in US media questioning if military pressure can force change without regime-toppling risks. For now, the focus remains on whether diplomacy can bridge the gap or if the region is headed for another volatile chapter.
