Geneva Round Three: US-Iran Nuclear Talks Resume Amid Military Buildup and Scope Disputes
Standout: The United States and Iran are holding their third round of nuclear negotiations in Oman this week, even as the largest US military concentration in the Middle East since 2003 continues to expand. The talks face structural obstacles—including a US demand to include Iranian conventional missiles in any deal—that both sides' actions suggest they expect to fail.
The United States and Iran resumed nuclear negotiations in Muscat, Oman, on February 24, 2026, with US envoys Steven Witkoff and Jared Kushner leading the American delegation. Iranian Foreign Minister Sadegh Ghalibaf confirmed Iran's participation via state media. This marks the third attempt at diplomatic engagement since President Donald Trump proposed direct talks in January, following nearly two years of escalating military pressure, covert strikes, and economic warfare.
What is at stake
The negotiations center on whether Iran will accept limits on uranium enrichment in exchange for sanctions relief and normalized trade. But the scope of the talks has expanded beyond the nuclear file: US Secretary of State Marco Rubio stated on February 21 that any agreement must also address Iran's ballistic missile program and include "trilateral arms control" involving Russia and China—a demand Iran has rejected in previous negotiating rounds.
The military backdrop is unprecedented. According to Reuters, the US has deployed two aircraft carrier strike groups (USS Eisenhower and USS Theodore Roosevelt), THAAD missile defense batteries, B-2 stealth bombers, and additional F-22 squadrons to the region. This represents the largest sustained US military presence in the Middle East since the 2003 invasion of Iraq, based on naval and air force asset counts reported by the Pentagon and regional tracking services.
Iran, meanwhile, has dramatically accelerated oil exports in recent weeks. Kpler, a commodity tracking firm, reports that Iranian tankers loaded 20.1 million barrels of crude in the first three weeks of February—a 40% increase from January. Bloomberg's satellite imagery analysis corroborates this surge, showing Iran's largest export push since the reimposition of US sanctions in 2018. Iranian officials have not explained the timing, but energy analysts interpret it as hedging against the risk of renewed strikes on export infrastructure or tighter enforcement of sanctions if talks collapse.
The nuclear dispute: what both sides claim
The core disagreement remains Iran's uranium enrichment program. The 2015 Joint Comprehensive Plan of Action (JCPOA)—signed by Iran, the US, UK, France, Germany, Russia, and China—capped Iran's enrichment at 3.67% purity and limited stockpiles to 300 kilograms. The US withdrew from the agreement in 2018 under President Trump's first term, reimposing sanctions. Iran responded by progressively exceeding the deal's limits, reaching 60% enrichment by 2021—close to the 90% threshold considered weapons-grade.
The International Atomic Energy Agency (IAEA) reported in December 2025 that Iran had accumulated approximately 130 kilograms of uranium enriched to 60%, enough material to theoretically produce multiple nuclear weapons if further enriched. Iran maintains that its program is for civilian energy and medical isotope production, a position it has held consistently since 2002.
The dispute intensified in June 2025, when Israel launched a twelve-day air campaign targeting Iranian nuclear sites, with US support. Israeli and US officials claimed the strikes destroyed centrifuge facilities at Fordow, Natanz, and Isfahan, as well as Iran's Russian-supplied S-300 air defense systems. Iran acknowledged damage but disputed the extent. IAEA inspectors have not been permitted to verify what, if anything, remains operational at the three sites—a point Iran's UN envoy raised in January, calling US claims "unsubstantiated."
US National Security Adviser JD Vance stated on February 18 that intelligence assessments suggest Iran has "resumed reconstruction" of centrifuge infrastructure and could return to pre-strike enrichment capacity within 12-18 months. Iran's foreign ministry called this characterization "fabricated pretexts," but declined to provide independent verification or allow expanded IAEA access.
Why the talks may be structurally blocked
The expansion of negotiation scope to include missiles and multilateral arms control introduces what several analysts describe as a "poison pill." Michael Singh, a former senior director for Middle East affairs at the National Security Council, told Foreign Policy: "By the pattern established in prior US-Iran negotiations, when one side expands scope significantly—especially to include issues requiring third-party cooperation—it is typically a signal that the expanding party does not expect agreement."
Iran has historically rejected linking its ballistic missile program to nuclear talks, arguing that missiles are a sovereign defensive capability separate from proliferation concerns. The trilateral arms control demand is even more challenging: it would require Russian and Chinese participation, neither of which has indicated willingness to constrain Iran's conventional arsenal.
Rubio's framing explicitly ties any deal to broader regional security architecture. In a February 21 press briefing, he said: "We are not interested in a narrow nuclear arrangement that leaves Iran free to threaten its neighbors with increasingly sophisticated missiles. Any deal must address the full spectrum of threats." This represents a significant departure from the Obama administration's approach, which deliberately kept the JCPOA focused solely on the nuclear file to maximize the chance of agreement.
European signatories to the original JCPOA—France, Germany, and the United Kingdom—have not publicly endorsed the expanded scope. French Foreign Minister Jean-Noël Barrot told Le Monde on February 20 that "while missile proliferation is a legitimate concern, conflating it with nuclear negotiations risks making both problems unsolvable." The E3's position creates a potential rift within the Western coalition: if the US insists on expanded terms that Europe considers unrealistic, transatlantic unity on sanctions enforcement may weaken.
The military dimension: buildup or bluff?
The scale of US military deployment has prompted debate about whether Washington is preparing for imminent strikes or using force posture for diplomatic leverage.
David Petraeus, former CIA director and retired four-star general, told Foreign Policy on February 19: "The force package assembled is consistent with a major strike campaign, not a symbolic show of force. The question is whether the administration has done the missile math—how many targets, how many sorties, how sustainable is follow-on enforcement if Iran rebuilds."
Two unnamed US officials told Reuters on February 17 that "advanced military planning" is underway, but characterized it as contingency preparation rather than a committed course of action. The Pentagon has declined to comment on operational timelines.
Iran has responded with its own signaling. Hezbollah, Iran's Lebanese ally, issued a statement on February 22 indicating it would not intervene in any US-Iran conflict unless attacks directly threaten Supreme Leader Ali Khamenei or key regime figures—a position that, if credible, would limit the risk of regional escalation. Israel's intelligence assessment, leaked to Haaretz, suggests Hezbollah's restraint is genuine due to its own force degradation from prior conflicts and Lebanon's economic collapse.
However, military mobilization creates its own momentum. Once deployed, forces generate bureaucratic and political pressure to act. The 1990-91 Gulf War buildup took six months; current deployments happened in six weeks. Some analysts argue this compressed timeline suggests either genuine urgency or deliberate pressure to force Iranian concessions before midterm elections.
Actor incentives and constraints
The United States faces conflicting pressures. Trump campaigned in 2024 on ending "forever wars" but also on restoring "maximum pressure" on Iran. His base remains skeptical of military intervention, but a quick, successful strike that degrades Iran's nuclear capacity without triggering regional war could be politically viable. The presence of Jared Kushner—Trump's son-in-law with deep business and diplomatic ties to Gulf monarchies and Israeli leadership—signals personal presidential investment in the talks. But Kushner's involvement also raises questions about whether Gulf and Israeli preferences are embedded in the US negotiating position.
Iran is constrained by severe economic pressure. International Monetary Fund estimates put Iran's inflation at 47% as of January 2026. Sanctions have reduced oil export revenue by approximately 80% since 2018. Domestic unrest, triggered by currency collapse and subsidy cuts, led to mass protests in 2022-2023. The US-based Human Rights Activists News Agency (HRANA), a diaspora organization monitoring protest casualties, reports over 7,000 confirmed deaths, including 6,488 protesters, though independent verification is impossible. The Iranian government claims approximately 3,100 deaths. Trump asserted in a February 15 speech that his administration's policies "killed at least 32,000 protesters"—a figure no independent source has corroborated and which Iranian officials denounced as false.
Iranian leaders have framed sanctions relief as an existential necessity. Khamenei told state media in January: "When the economy was collapsing and people couldn't feed their families, the missiles came to our rescue"—a statement suggesting that Iran's missile deterrent prevented total regime collapse by deterring invasion during economic crisis. This logic makes missile disarmament extremely difficult politically.
Gulf states, particularly Saudi Arabia and the United Arab Emirates, have quietly normalized relations with Iran in recent years through Chinese-mediated talks. Saudi Arabia reopened its embassy in Tehran in 2023. A nuclear-armed Iran would destabilize this détente, but a US-Iran war would also threaten Gulf oil infrastructure. The Gulf Cooperation Council has not publicly supported US military action.
Russia and China both maintain strategic relationships with Iran. Russia relies on Iranian military cooperation in Syria and views US pressure on Iran as part of broader containment. China is Iran's largest oil customer and has invested heavily in Iranian infrastructure through Belt and Road projects. Neither has indicated willingness to participate in arms control frameworks that constrain Iran, and both would likely veto any UN Security Council resolutions authorizing force.
What remains uncertain
Several critical factors remain unresolved or disputed:
Current enrichment capacity: While Iran exceeded JCPOA limits starting in 2019, reaching 60% purity by 2021, the exact operational status of its program post-June 2025 strikes is unclear. US claims of resumed reconstruction are not independently verified. If Iran retained significant capacity, the military threat calculation changes. If capacity was genuinely destroyed, the urgency of negotiations decreases.
Deal feasibility: Even if Iran agrees to nuclear limits, implementation requires lifting US sanctions—which, under current law, requires Congressional approval for permanent relief. Trump can waive sanctions temporarily, but cannot guarantee long-term commitments. Iran learned this in 2018 when Trump withdrew from the JCPOA despite it being a sitting agreement. This credibility gap makes durable arrangements difficult.
Scope flexibility: Rubio's public statements emphasize maximalist demands, but diplomatic negotiations often involve face-saving mechanisms. It is possible the US will quietly drop or defer missile demands in exchange for stricter nuclear verification, while maintaining public rhetoric about comprehensive terms. Alternatively, the expanded scope could be deliberate deal-breaking.
Red lines: Both sides have stated positions that appear mutually exclusive. Iran has said it will not negotiate on missiles. The US has said it will not accept a deal without missile limits. One side must compromise, or talks will fail. Which side blinks—or whether both sides prefer failure to concession—will determine the outcome.
What this means
The Geneva talks are occurring, but the conditions for success are not evident. The military buildup is real, but its purpose—coercion, contingency, or committed action—remains ambiguous. Iran's oil surge reflects rational hedging, not necessarily escalatory intent. The US is simultaneously negotiating and preparing for strikes, which is standard great power behavior under uncertainty.
The most likely near-term outcomes are:
1. Stalemate: Talks continue without breakthrough, military pressure persists, Iran maintains its hedging posture. This is the historical norm.
2. Limited deal: US quietly drops missile demands or defers them to "phase two" talks; Iran accepts enhanced IAEA inspections and enrichment caps. Both sides claim victory. Enforcement disputes begin immediately.
3. Collapse and strikes: Iran rejects expanded scope, US proceeds with airstrikes on nuclear sites. Regional war risk depends on Hezbollah restraint and Israeli actions.
The 72-hour window for Iranian response to Rubio's scope expansion, flagged by diplomatic sources, is the next critical signal. If Iran rejects outright, option 3 becomes more likely. If Iran engages on modified terms, option 2 remains possible.
The diplomatic track is real. But so is the military track. Both can coexist until the moment a decision is forced.
