Assessing the Implementation and Implications of the Cyrus Accord’s Latest Protocol
Executive Summary
The Cairo Agreement, brokered in late 2024 as a supplemental protocol to the overarching Cyrus Accord, represents a critical, though precarious, attempt to resurrect nuclear inspections within Iran. Following years of constrained access and escalating tensions, the agreement aims to facilitate greater International Atomic Energy Agency (IAEA) oversight of Iran’s nuclear facilities in exchange for limited sanctions relief and security guarantees. While the agreement represents a diplomatic achievement, its implementation faces substantial headwinds from hardliners in both Iran and the United States, alongside ongoing regional instability. Success is contingent upon sustained political will, predictable adherence to commitments, and a reduction in external interference. Failure to solidify the Cairo Agreement risks further proliferation concerns and a potential return to heightened regional conflict.
Background
The Cyrus Accord, formally signed in 2022, emerged from a series of secret negotiations initiated in Muscat, Oman, following a period of maximalist policies pursued by the previous United States administration. The Accord aimed to de-escalate tensions between Israel and Iran, primarily through a tacit understanding involving security guarantees for both nations and a commitment from Iran to significantly constrain its nuclear programme. However, the initial Accord lacked robust verification mechanisms, leading to mutual distrust and accusations of non-compliance. Israel, while maintaining a policy of strategic ambiguity, expressed concerns over the lack of ‘anytime, anywhere’ access for inspectors and the potential for Iran to advance its nuclear capabilities under the guise of civilian research. Iran, conversely, accused Western powers of failing to deliver on promised economic benefits and questioned the sincerity of assurances regarding its security. The need for a more concrete inspection protocol led to the Cairo negotiations facilitated by Egypt, culminating in the Cairo Agreement in late 2024.
Current Status
As of early 2025, the implementation of the Cairo Agreement remains severely challenged. While IAEA inspectors have gained limited re-entry into previously restricted sites, including the Parchin complex, access has been subject to stringent conditions and bureaucratic delays. Iran maintains that all access is granted within the framework of its sovereign rights and the Additional Protocol to the Non-Proliferation Treaty (NPT), thereby rejecting requests deemed ‘intrusive’ or politically motivated.
Critically, the United States has only partially eased sanctions as stipulated in the agreement, citing ongoing concerns about Iran’s regional activities and missile programme. This delay has fuelled resentment within Iran’s political elite and strengthened the position of hardliners who argue that negotiations with the West are futile. Simultaneously, Israel has expressed continued scepticism, conducting periodic military exercises that are widely perceived as a signal of its readiness to take unilateral action should it perceive an imminent Iranian nuclear breakthrough. Public statements from both Tehran and Jerusalem underscore a deeply entrenched lack of trust that threatens to derail the implementation process. Several smaller breaches of protocol have been reported by the IAEA, though these are currently being managed through diplomatic channels.
Key Provisions or Developments
The Cairo Agreement pivots around several key provisions aimed at bolstering nuclear verification. Firstly, it establishes a ‘Joint Monitoring Commission’ (JMC), composed of representatives from Iran, the United States, the European Union, and the IAEA, to address disputes and monitor compliance. Secondly, it mandates the installation of enhanced monitoring equipment at declared nuclear facilities, including advanced surveillance cameras and real-time data transmission systems. This supplements the existing safeguards regime outlined in the NPT.
A crucial element involves the resolution of ‘outstanding questions’ related to Iran’s past nuclear activities, specifically pertaining to alleged weapons-related research conducted before 2003. The Agreement allows for the IAEA to pursue these investigations, but with Iranian oversight and a commitment to protecting sensitive national security information. This remains a point of contention, as Israel and several Western powers insist on a full accounting of past activities before any further sanctions relief is considered.
Notably, the agreement includes a novel ‘snapback’ mechanism tied not to a breach of the Cairo Agreement itself, but to a demonstrable escalation of Iran’s regional activities, defined as direct or indirect support for proxy groups engaged in hostilities against Israel or its regional allies. This provision reflects deep-seated security concerns held by Israel and its allies and introduces a significant geopolitical dimension into the nuclear equation. Finally, the agreement outlines a phased approach to sanctions relief, contingent on verifiable progress in resolving outstanding questions and maintaining full compliance with inspection protocols.
Regional Impact
The Cairo Agreement—and particularly its unsteady implementation—has had a noticeable but complex effect on the broader Middle East. Saudi Arabia and the United Arab Emirates, while publicly supportive of diplomatic efforts to curb Iran’s nuclear ambitions, remain wary of any perceived rapprochement between Washington and Tehran. These states have been actively pursuing their own security arrangements, including deepened defence cooperation with the United States and Israel, driven by a desire to counterbalance Iranian influence.
The agreement’s limitations—especially regarding regional activities—have also provided ammunition to regional actors criticising Iran’s destabilising role. Conversely, the agreement has heightened anxieties amongst Iran’s allies in Lebanon and Syria, who fear that a potential escalation of tensions could draw them into a wider conflict. The agreement’s success, or failure, will undoubtedly shape the forthcoming security architecture of the region and influence the calculus of regional power dynamics. It has, at the very least, lowered the immediate risk of open conflict, offering a respite in a volatile environment.
Outlook
The trajectory of the Cairo Agreement remains deeply uncertain. The ongoing political divisions within both Iran and the United States, combined with persistent regional rivalries, pose significant obstacles to its full implementation. The impending US presidential election in late 2026 introduces further uncertainty, as a change in administration could lead to a reversal of current policies. Sustaining the agreement will require sustained diplomatic engagement, a willingness to compromise on all sides, and a commitment to building trust. A failure to do so could lead to a resurgence of tensions, potentially culminating in military confrontation. Absent a significant breakthrough, the region will likely remain locked in a cycle of mistrust and insecurity.
