Muscat and the Limits of Iran-US Diplomacy

Diplomacy between the United States and Iran has once again converged on Muscat, the capital of Oman — a neutral site long suited for delicate talks — but the scope and expectations of the negotiations reveal how constrained the process remains. As indirect talks are scheduled to resume in Muscat this week, analysts and diplomats alike question whether the venue can overcome the deep mistrust and strategic differences that have long defined Iran-US relations.
Muscat: A Neutral Meeting Ground
Oman’s capital has emerged repeatedly over the past decade as a mediation hub for Iran and the United States. Unlike venues seen as more explicitly aligned with Western or regional powers, Muscat offers both sides a neutral environment that avoids overt symbolism. That neutrality has helped keep lines of communication open even in otherwise bleak moments.

In the current round, Iranian Foreign Minister Abbas Araghchi confirmed that nuclear negotiations with the U.S. will be held in Muscat, underscoring Oman’s continued diplomatic relevance. Iranian authorities publicly thanked their Omani counterparts for facilitating the talks and providing the space for dialogue, again highlighting the city’s role as a discreet intermediary.
But while the choice of Muscat might lower the temperature compared to other capitals, it does little to resolve the fundamental differences between Tehran and Washington.
Agenda Disagreements Reflect Deep Distrust
The talks themselves are narrow in scope and cautious in ambition. Tehran has insisted that the discussions focus strictly on its nuclear programme and nothing else — excluding issues such as missile development, regional proxy activity, and internal governance. That stance underscores Iran’s view that broader demands risk compromising its core strategic interests.

Washington, however, has sought to expand the agenda. U.S. officials have publicly suggested that ballistic missiles and Iran’s regional posture should be included alongside nuclear issues. That broader agenda, according to critics, reflects mounting pressure from allied capitals — notably Israel — that view a narrow nuclear focus as insufficient.

The U.S. insistence on tackling multiple security concerns simultaneously has been one of the main sticking points that nearly derailed talks before they arrived in Muscat. Iranian negotiators balked at such demands, regarding them as indirect pressure tactics rather than genuine diplomacy.

Domestic and Regional Pressures
Part of the difficulty stems from internal political divides on both sides. In the United States, figures such as Secretary of State Marco Rubio have articulated a hawkish approach, arguing that any meaningful agreement must address Iran’s missile capabilities and regional alliances as well as its nuclear programme. This stance reflects internal political pressure in Washington to adopt a comprehensive view of Iran’s influence.

Tehran, meanwhile, remains wary of conceding on anything that it perceives as core to its deterrence strategy. Iranian officials privately argue that agreeing to broader topics would invite further demands once one issue is settled. Observers note Tehran’s longstanding concern that concessions in one area — such as nuclear enrichment — would simply shift the focus of pressure to missiles or other strategic capabilities.

The result is a diplomatic standoff where both sides claim to desire peace and stability but remain deeply cautious about making compromises perceived as weakening their negotiating positions.
Muscat’s Role: Bridge or Band-Aid?
Oman’s efforts to host talks and facilitate communication are widely recognised diplomatically, but the choice of Muscat also reflects the limited options available. When direct dialogue is politically or symbolically difficult — as it has been almost continuously since the 1979 Iranian Revolution — a neutral venue becomes essential to even keep talks alive.

However, the fact that indirect talks are used — with delegations in separate rooms communicating via intermediaries — suggests that trust remains minimal. This format has been a staple of past rounds, where neither side is willing to engage in direct, face-to-face negotiation.

The indirect nature of the discussions underlines a broader limitation: even when diplomacy is possible, it is tightly controlled, with both sides wary of entering a process that could be seen domestically as capitulation. That tension is part of why expectations for Muscat are modest, even cautious.

External Influences and Broader Tensions
Another factor limiting Muscat diplomacy is the broader geopolitical context. Regional anxieties, particularly regarding Israeli military actions and the Israel-Iran rivalry, have influenced both U.S. and Iranian calculations. Gulf states — for whom any conflict between Iran and America would have immediate repercussions — have a vested interest in de-escalation. Yet those same regional tensions complicate negotiations.

Analysts such as Trita Parsi of the Quincy Institute argue that U.S. policy is influenced not solely by direct national interest but also by the strategic priorities of allies like Israel, which continues to advocate for confrontation rather than compromise. Pursuing such policy directions further limits the diplomatic room for manoeuvre.

Modest Goals, Significant Risks
Despite the difficulties, both sides appear committed to keeping the talks alive for now, even if only as a mechanism to manage tensions rather than resolve them comprehensively. Tehran has taken small confidence-building steps, such as postponing military exercises in the Persian Gulf and lowering the intensity of rhetoric around missile programmes.

Washington, too, is maintaining a diplomatic track while visibly reinforcing its military posture in the region, as seen by the continued presence of American forces and carrier groups in nearby waters. These simultaneous push-and-pull strategies underscore the fundamental duality of current policy: seek engagement while preparing for confrontation if diplomacy fails.
Conclusion: A Diplomatic Path with No Clear End
Muscat remains, for now, the centre stage of U.S.-Iran diplomacy — but the limitations of these talks are stark. Venue and format can create space for conversation, but they cannot by themselves bridge the deep mistrust, conflicting national interests, and regional pressures that underpin the standoff.
Dawn
What is clear is that both Tehran and Washington are using diplomacy not as an endpoint but as a way to manage risk and project strategic posture. Muscat’s role will continue to be significant as long as neither side is prepared to confront the core issues directly in a more robust negotiating framework — a situation that leaves the future of U.S.-Iran relations as uncertain as ever.
