Assessing the Risks and Rewards of the Emerging Entente
Executive Summary
The Cyrus Accord, a series of discreet, bilateral understandings between Israel and Iran beginning in 2022, represents a dramatic, if precarious, shift in decades-long animosity. Driven by shared concerns over regional instability and the perceived failings of the Joint Comprehensive Plan of Action (JCPOA), the Accord prioritises de-escalation and limited cooperation on security matters, primarily focused on containing perceived extremist threats. While proponents highlight reduced prospects of direct conflict and new avenues for intelligence sharing, sceptics voice concerns about the Accord’s opaqueness, potential for exploitation by Iran, and implications for Israel’s relationships with its traditional allies. Current implementation remains uneven, marked by mutual distrust and persistent covert activity; the Accord’s long-term viability hinges on sustained political will and demonstrable adherence to its unstated principles.
Background
For over four decades, Israel and Iran have existed in a state of proxy conflict, punctuated by covert operations and mutual hostility. The 1979 Iranian Revolution fundamentally altered the regional landscape, leading to the establishment of a theocratic regime vehemently opposed to Israel’s existence. Following the United States’ withdrawal from the JCPOA in 2018 and the subsequent reimposition of sanctions, Iran’s nuclear programme resumed its advancement, escalating regional tensions. Simultaneously, both states encountered increasing challenges from non-state actors, particularly those aligned with – or exploiting – the chaos in Syria, Iraq, and Yemen.
The Cyrus Accord emerged from a series of clandestine negotiations, facilitated by Omani intermediaries, beginning in late 2022. Initial impetus came from a shared, albeit begrudging, acknowledgement that outright conflict between Israel and Iran would be catastrophic for both nations and the wider region. The Accord’s objectives were thus framed in terms of ‘mutual deterrence’ and ‘managed competition’. Rather than comprehensive normalisation, the focus was on establishing ‘red lines’ and implementing discrete measures to avoid direct confrontation, with an initial focus on containing extremist groups operating near their respective borders. The invocation of Cyrus the Great, the founder of the Achaemenid Empire known for his tolerance and diplomacy, was a carefully curated symbolic gesture intended to signal a potential shift in paradigm.
Current Status
The current status of the Cyrus Accord is best described as ‘fragile implementation’. While confirmed by officials in both nations – though cautiously worded and often lacking specific detail – the Accord remains largely opaque, with both governments refraining from public acknowledgement of the full scope of understandings. Reports suggest an informal, unwritten agreement governs issues such as notification of military exercises, restrictions on cyber activity targeting critical infrastructure, and deconfliction in Syria and Iraq.
Intelligence sharing, specifically related to monitoring the activities of groups like ISIS and affiliated networks, constitutes a core, yet heavily guarded, aspect of the Accord. Israel reportedly shares intelligence on Iranian proxy networks, whilst Iran provides information regarding Sunni extremist groups. However, verification remains a major challenge. Both states retain significant scepticism regarding the other’s motives and compliance.
Recent escalations, including alleged Israeli strikes against Iranian personnel in Syria and recurring cyberattacks, demonstrate the precarious nature of the entente. These incidents, while not triggering a full-scale conflict, have repeatedly tested the limits of the Accord and fuelled criticism from hardliners in both countries. There are also persistent allegations of Iranian continued support for groups actively opposing Israel, undermining trust.
Key Provisions or Developments
The Cyrus Accord does not represent a single, legally binding treaty, but rather a collection of tacit understandings and operational protocols. A crucial element is the establishment of ‘de-escalation zones’ – geographically limited areas in Syria and Iraq where both states have ostensibly agreed to reduce their military and intelligence activity. This has led to a noticeable reduction in high-profile clashes between Iranian-backed militias and Israeli-aligned forces in these regions, although low-intensity conflict continues.
Further development centres around the coordination of responses to common threats. After repeated attacks on oil tankers in the Persian Gulf, attributed to various actors, both Israel and Iran discreetly increased naval patrols and enhanced maritime security cooperation, halting the escalation. However, this cooperation has provoked anger from the United States, which views Iranian presence in the Gulf as destabilising.
A controversial aspect, and a source of significant concern for regional allies of Israel, is the alleged ‘quid pro quo’ arrangement regarding Iran’s nuclear programme. Reports suggest that in exchange for a tacit Israeli acceptance of Iran’s current enrichment levels – far exceeding JCPOA limits – Iran has scaled back support for certain anti-Israeli militant groups in Lebanon and Gaza. Critics argue this constitutes a tacit endorsement of Iran’s nuclear ambitions and weakens international efforts to restrain its programme. Another related development is the shift in rhetoric regarding regional power dynamics. Both states appear to be adopting a more pragmatic approach, acknowledging each other’s influence and reducing bellicose statements, although this remains primarily confined to back channels.
Regional Impact
The Cyrus Accord has sent ripples throughout the Middle East, provoking a mixed reaction. Saudi Arabia and the United Arab Emirates, long-time rivals of Iran and staunch allies of the United States, view the Accord with extreme suspicion, fearing it will consolidate Iranian influence and marginalise their role in regional security. These nations have reportedly sought reassurances from Washington and intensified their own efforts to counter Iranian influence.
The Palestinian Authority feels similarly sidelined, worried that the Accord prioritises Israeli security concerns over the Palestinian question. They perceive Israel’s willingness to engage with Iran as a betrayal of the pan-Arab solidarity necessary to advance the Palestinian cause.
Conversely, some regional actors, particularly Oman and Iraq, have played a constructive role in facilitating dialogue and view the Accord as a positive step towards de-escalation. The reduction in proxy clashes in Iraq, for instance, has contributed to a degree of stability. However, this stability is fragile and contingent on continued implementation of the Accord’s tenets.
Outlook
The long-term viability of the Cyrus Accord remains deeply uncertain. The inherent distrust between Israel and Iran, coupled with their divergent strategic interests, presents a formidable challenge. Domestic political considerations in both countries could easily derail the process. A change in government in either nation, or a significant escalation involving a third party, could rapidly undo the gains achieved to date.
Despite these risks, the Accord represents a pragmatic attempt to manage a dangerous situation. If both sides demonstrate sufficient political will and commit to genuine de-escalation, it could pave the way for a more stable, albeit uneasy, coexistence. However, this requires transparency, verifiable compliance, and a broader regional framework that addresses the legitimate security concerns of all stakeholders. In the absence of these factors, the Cyrus Accord risks becoming a temporary reprieve, masking underlying tensions that could erupt into conflict at any moment.
