On April 12, the United States and Iran convened in Muscat, Oman, for their first publicly acknowledged nuclear negotiations since the US withdrawal from the Joint Comprehensive Plan of Action (JCPOA) in 2018. Despite initial descriptions of the talks as “constructive” the prospects for a sustainable agreement remain bleak. It was a complex assortment of strategic, political, and military factors that made a resolution with Iran impossible over the past decade, and there’s little to suggest that anything has changed in the current context. These factors include:
Divergent Objectives and Non-Negotiable Demands
The fundamental discord between US and Iranian objectives presents a significant barrier to successful negotiations. The United States, under President Donald Trump, insists on the complete dismantlement of Iran’s nuclear infrastructure, cessation of ballistic missile development, and termination of support for regional proxy groups. Conversely, Iran has consistently claimed that its nuclear program is solely for peaceful purposes and refuses to halt uranium enrichment or relinquish its missile capabilities. Iranian Foreign Minister Abbas Araghchi has indicated that while Iran is open to dialogue, it will not accept terms that compromise its sovereignty or defense capabilities. Furthermore, while Iran is likely to seek sanctions relief from the United States, Washington is unlikely to comply unless Iran takes decisive action to dismantle its nuclear infrastructure, a move that Iran is unlikely to readily undertake.
Mutual Distrust and Historical Grievances
The legacy of mistrust between the U.S. and Iran undermines the foundation necessary for effective diplomacy. Supreme Leader Ayatollah Ali Khamenei has historically opposed direct negotiations with the U.S., viewing Washington as an unreliable partner. Iran’s experiences with economic sanctions and military threats exacerbate this skepticism, reinforcing the perception of the U.S. as an adversary. Furthermore, Iran’s longstanding aggressive behavior and ambitions of influencing the political and security landscape of the Middle East have left regional US allies, more specifically the Gulf Cooperation Council (GCC) nations, under constant security threat.
Internal Political Dynamics and Hardliner Influence
Iran’s internal political landscape is mainly dominated by hard-line factions that are resistant to concessions perceived as capitulations to Western pressure. The Islamic Revolutionary Guard Corps (IRGC), a powerful entity within Iran, benefits from the continuation of a confrontational stance toward the U.S. Any agreement that appears to undermine Iran’s strategic autonomy or defense capabilities is likely to face significant domestic opposition, making it politically untenable for Iranian negotiators to acquiesce to US demands. Iranian hardliners will always remain skeptical of US intentions, fearing that concessions could undermine the regime’s legitimacy and control.
Geopolitical Tensions and Proxy Conflicts
Geopolitical tensions stemming from Iran’s involvement in regional conflicts, including support for groups in Syria, Yemen, Lebanon, and various groups in Iraq, have exacerbated tensions with the U.S. and its allies for many years. A recent example is the Red Sea crisis, where Iran-backed Houthis in Yemen have eroded the security of a key maritime shipping corridor. Despite the US-led strikes aimed at degrading the Houthis’ capabilities, Iran’s ongoing support for the group remains a source of distrust.
Washington and its regional Arab allies view Iran’s regional activities as inherently destabilizing, and in turn they typically seek to curtail Tehran’s influence. However, Iran has always also considered its regional engagements as essential to its national security and ideological commitments to building the Shiite Crescent. The negotiation landscape is further complicated by the long-standing fundamental and ideological disagreement over regional policy. Any comprehensive agreement would necessitate Iran curtailing these activities, a demand Tehran is unlikely to meet given its investment in regional influence as a means of strategic depth and deterrence.
External Pressures and the Role of Third Parties
The involvement of external actors, such as Israel and Saudi Arabia, adds layers of complexity to US-Iran negotiations. Israel, in particular, has expressed strong opposition to any agreement that does not fully dismantle Iran’s nuclear capabilities and has indicated a willingness to take unilateral military action if necessary. These external pressures constrain the negotiating space and increase the risk of conflict escalation, reducing the likelihood of a successful diplomatic outcome. In addition, as the U.S. and Saudi Arabia advance on recently announced civil-nuclear cooperation, Iran is likely to remain firm on its own nuclear development.
Economic Sanctions and Domestic Concerns
While economic sanctions have exerted significant pressure on Iran, leading to a willingness to engage in talks, they have also fostered resentment and a sense of injustice among the Iranian populace. The societal impact of sanctions, including shortages of essential goods and services, complicates the domestic political environment and reduces the government’s flexibility in negotiations. Any agreement perceived as insufficient to alleviate economic hardships is unlikely to gain popular support within Iran, especially from the hard-line factions.
Given the fact that Iran’s economy has been severely impacted by international sanctions, leading to domestic unrest and national protests against the regime, Tehran is going to firmly seek substantial sanctions relief as a condition for any agreement. However, the U.S. remains cautious about lifting sanctions without concrete assurances of Iran’s compliance, creating a deadlock where neither side is willing to make the first move.
Time Constraints and Escalation Risks
President Trump’s administration has set a two-month deadline for negotiations, with the implicit threat of military action should talks fail. This compressed timeline limits the opportunity for thorough diplomatic engagement and increases the risk of miscalculation. It can be well understood the US stance on setting a strict timeline, given that the history of Iran with negotiations shows that the latter only engages in negotiations to buy time while actively developing its nuclear program.
The presence of US military forces in the region, coupled with Iran’s potential to expel IAEA inspectors, heightens the possibility of a rapid escalation into an open conflict. The US military’s presence in the region is crucial for strategic deterrence against the Iranian threat, yet how Iran will react on different fronts will remain a source of complexity in the negotiation process. This includes Iran’s continuous maritime harassment in the Strait of Hormuz and its support for Yemen’s Houthis.
