Why Rapprochement with Iran May Become Unavoidable

Saudi Arabia faces a strategic dilemma in which military deterrence, economic transformation and regional diplomacy are increasingly interconnected. The latest escalation involving Yemen’s Houthis has exposed vulnerabilities extending from Saudi territory and critical energy infrastructure to the Red Sea and Bab el-Mandeb. On 19 September 2026, Saudi authorities reported intercepting a ballistic missile launched towards Riyadh, while the Houthis claimed to have attacked targets in Riyadh and the Saudi oil hub of Yanbu. The escalation followed Houthi advances along Yemen’s Red Sea coast and intensified attacks on Saudi territory and maritime interests.
These developments reinforce a broader strategic reality: Iran remains an unavoidable variable in Saudi Arabia’s security equation. Yet the Iranian-Houthi relationship requires analytical precision. Tehran has provided the Houthis with military, technological, financial and political support, contributing to their missile and drone capabilities. At the same time, Houthis retain significant organisational and strategic autonomy.
Iranian support has significantly enhanced Houthi military capabilities and regional reach, enabling threats to Saudi territory, energy infrastructure and Red Sea shipping while extending Tehran’s strategic influence across the Arabian Peninsula. Yet characterising the Houthis simply as an Iranian “proxy” obscures their political and operational autonomy. Chatham House research emphasises that Houthi decision-making is shaped not only by ties to Tehran but also by Yemen’s domestic political dynamics, the movement’s strategic interests, and its pursuit of power and legitimacy.
This distinction has direct implications for Saudi policy. Rapprochement with Iran would not automatically neutralise the Houthi threat, but Iranian influence makes Tehran an indispensable interlocutor in efforts to contain regional escalation. Recent Chinese efforts to encourage Iran to restrain the Houthis following a Saudi appeal illustrate this dual reality: Tehran does not exercise complete command over the movement, but its influence remains strategically consequential.
Saudi Arabia’s expanding security partnerships reflect an effort to reduce dependence on any single external power. The United States remains central through defence technology, intelligence, training and logistics, but the recent Houthi escalation has underscored the limits of relying exclusively on US military intervention. Riyadh has consequently broadened its strategic relationships, deepening formal defence cooperation with Türkiye and Pakistan while expanding diplomatic, economic, maritime and regional-security coordination with China, Egypt, the UAE, and, more cautiously, Israel.
The Mecca Joint Defence Agreement with Türkiye and Pakistan represents a significant extension of this diversification, while Saudi coordination with China and other regional powers provides additional diplomatic and economic channels. Collectively, these relationships strengthen Riyadh’s resilience and strategic flexibility.
They cannot, however, alter the Kingdom’s geography. Iran’s proximity, missile and drone capabilities, regional partnerships and influence among armed non-state actors create persistent risks to Saudi territory, energy infrastructure and maritime interests. For Vision 2030, the economic consequences are particularly significant: the IMF’s 2026 assessment found that regional conflict disrupted shipping, oil exports and investor confidence, underscoring the vulnerability of Saudi economic transformation to prolonged instability.
Strategic diversification can therefore reduce dependence on individual security providers, but it cannot substitute for managing Saudi Arabia’s relationship with Iran. This structural constraint makes rapprochement a potentially necessary complement to deterrence and defence diversification.
The March 2023 Saudi-Iranian agreement provides an important precedent. Brokered by China, the agreement restored diplomatic relations and reflected Riyadh’s strategic and economic calculations, including the need for a more stable regional environment conducive to Vision 2030.
The precedent remains relevant because Saudi Arabia need not regard Iran as a trusted partner to pursue pragmatic risk reduction. Nor would rapprochement require abandoning its defence relationships with Washington, Türkiye or Pakistan. A renewed accommodation could instead focus on preventing attacks on Saudi territory and energy infrastructure, reducing maritime escalation, establishing crisis-communication mechanisms and clarifying limits around support for regional armed groups.
Such an arrangement would face substantial constraints. Iranian influence over the Houthis is significant but not absolute; verification would remain difficult; and Riyadh and Tehran would continue to compete over regional interests. Nevertheless, scholarship on Saudi-Iranian relations indicates that pragmatic engagement and periods of de-securitisation remain possible despite persistent rivalry.
Thus, rapprochement need not signify strategic alignment; it can function as an instrument of risk management and regional stability.
Saudi Arabia’s security dilemma cannot be resolved through military diversification alone. Türkiye, Pakistan, the United States, China and other partners can expand Riyadh’s strategic options, but none can remove Iran from its immediate security environment. The Houthi challenge demonstrates the limits of both approaches: Iranian support strengthens the movement, but its autonomy means that Tehran cannot simply command it.
The strategic implication is therefore a dual approach: credible deterrence against immediate threats combined with sustained engagement with Iran to manage the conditions that enable regional escalation. Such rapprochement would not imply trust, alignment or appeasement. It would represent pragmatic diplomacy within a condition of strategic interdependence.
For Riyadh, strategic autonomy may ultimately depend not on choosing between deterrence and rapprochement, but on combining the two. Iran’s influence over the Houthis is too consequential to ignore, while the Houthis’ autonomy makes exclusive reliance on Tehran equally insufficient. Rapprochement with Iran may consequently become unavoidable — not because Saudi Arabia can eliminate its strategic differences with Tehran, but because sustainable security requires managing a regional power that geography makes impossible to escape.
