Iran’s military escalation in the Gulf: Risks of widening regional conflict
The trajectory of Iran’s current military escalation against Gulf states reflects a profound strategic miscalculation-one that risks eroding Tehran’s diplomatic capital, widening regional fault lines and inviting consequences that may ultimately weaken Iran itself. A careful examination of the unfolding crisis reveals that alternative pathways were available to Tehran, pathways that could have preserved political sympathy across the Arab world while strengthening its negotiating leverage. Instead, the decision to widen the theater of confrontation has placed the entire Gulf region on the brink of dangerous instability.
To understand the gravity of the moment, consider a counterfactual scenario. When US and Israeli forces struck Iranian territory, Tehran could have confined its retaliation strictly to military targets directly associated with those operations-namely Israeli and US naval assets operating at sea. Such a calibrated response would have reinforced Iran’s narrative of self-defense while avoiding the expansion of hostilities into neighboring Arab states. Under that framework, members of the Gulf Cooperation Council (GCC), along with Jordan and Iraq, would likely have remained outside the targeting matrix.
Precedent supports this assessment. During the June 2025 confrontation between Tehran and Tel Aviv, Gulf states uniformly condemned what they characterized as Israeli aggression against Iranian sovereignty. Despite longstanding geopolitical tensions with Iran, Arab capitals adopted positions grounded in respect for territorial integrity and international law. Even states traditionally wary of Iranian regional ambitions refrained from endorsing military strikes on Iranian soil. That diplomatic posture would likely have persisted had Iran exercised restraint.
Similarly, if the assassination of Supreme Leader Ali Khamenei had occurred at a time of improving Arab-Iranian relations, condemnation and sympathy would almost certainly have followed. Regional norms still prioritize opposition to political assassinations and violations of sovereignty. The response to the death of former Iranian President Ebrahim Raisi in a helicopter crash in May 2024 demonstrated this dynamic. Gulf states dispatched official delegations to convey condolences, underscoring a recognition that humanitarian diplomacy transcends political rivalry.
In short, Tehran possessed a reservoir of political goodwill-fragile but tangible. By framing itself as a state subjected to external military aggression, Iran could have strengthened its moral and diplomatic standing. Instead, from the first days of escalation, Iranian missiles and drones reportedly targeted multiple Gulf states, including Oman-a country that had invested significant diplomatic capital in mediation efforts.
Oman’s role is particularly illustrative. Under the stewardship of Foreign Minister Badr Al-Busaidi, Muscat sought to preserve backchannel communication and prevent war. Omani diplomacy has historically functioned as a stabilizing conduit between adversaries, including Washington and Tehran. Yet even Oman reportedly witnessed attacks on ports and vessels within its waters. Such actions undercut Iran’s credibility and diminish the incentives for neutral intermediaries to continue mediation.
Iranian officials have attempted to justify the widening of targets by asserting that US military installations in Gulf countries constitute legitimate objectives. Ali Larijani, secretary of Iran’s Supreme National Security Council, argued that bases used by the United States to conduct operations against Iran are effectively “American soil.” According to this reasoning, states hosting such facilities assume the risks associated with US military deployments.
However, this argument is strategically flawed on several levels. First, Gulf states-particularly Saudi Arabia-have explicitly declared that their territories, airspace and territorial waters will not be used as launch points for attacks against Iran. Whether Tehran trusts those assurances is secondary; what matters is that these governments have publicly articulated non-belligerent positions. To disregard those statements risks alienating potential diplomatic partners.
Second, reports indicate that Iranian strikes were not confined strictly to US-designated military facilities such as Al Udeid in Qatar, Al Dhafra in the UAE or Juffair in Bahrain. Instead, the targeting allegedly extended to civilian infrastructure and economic assets. Energy facilities in Ras Tanura, airports in Kuwait and Dubai, and symbolic landmarks such as the Burj Al Arab have no plausible connection to US operational planning. Attacks on such sites undermine any claim of limited, defensive retaliation.
Most alarming is the reported targeting of the US Embassy in Riyadh. Diplomatic premises are protected under international law, including the 1961 Vienna Convention on Diplomatic Relations and the Geneva Conventions. Saudi Arabia’s Ministry of Foreign Affairs issued a sharply worded statement condemning the attack and affirming its right to take all necessary measures to protect its security and sovereignty. The legal and normative implications of striking a diplomatic compound are severe, particularly in a region where embassies symbolize not merely foreign presence but international legitimacy.
Riyadh’s response has so far been measured. Saudi Arabia has refrained from direct military retaliation, signaling a preference for de-escalation and diplomatic resolution. This restraint is consistent with the Kingdom’s broader strategic recalibration in recent years, which has emphasized economic transformation, regional stabilization and pragmatic engagement-even with traditional adversaries.
Yet restraint should not be mistaken for passivity. Saudi policy statements have underscored that continued aggression, civilian casualties or disruption to energy infrastructure could compel a shift in posture. The Gulf region’s economic architecture is deeply interconnected. Energy exports, shipping lanes and aviation hubs form the backbone of both regional prosperity and global supply chains. Any sustained disruption would reverberate beyond the Middle East, impacting oil markets, inflation dynamics and international trade flows.
From a strategic calculus standpoint, Iran’s current trajectory risks several adverse outcomes.
First, it may consolidate a more unified Arab security alignment against Tehran. Historically, divisions among Gulf states have limited collective responses to Iranian influence. Direct attacks on civilian and economic targets, however, narrow political space for accommodation. Even states inclined toward neutrality may feel compelled to strengthen defense cooperation.
Second, escalation increases the likelihood of miscalculation. Missile strikes on energy facilities or maritime assets could provoke retaliatory cycles difficult to contain. The Persian Gulf’s geography-narrow waterways, dense infrastructure and proximity of military assets-magnifies escalation risks. A single incident could trigger broader confrontation.
Third, Iran’s economic vulnerabilities remain acute. Sanctions, currency instability and domestic pressures constrain Tehran’s capacity for prolonged conflict. Expanding hostilities may exacerbate isolation and deter potential investment or diplomatic normalization. In contrast, Gulf states-particularly Saudi Arabia and the UAE-possess deeper financial reserves and diversified economic strategies.
Fourth, the reputational cost to Iran is substantial. By extending strikes beyond direct military adversaries, Tehran forfeits the moral high ground it might otherwise claim as a victim of external aggression. International public opinion is often shaped less by legal nuance than by perceptions of proportionality and restraint. Civilian infrastructure strikes weaken Iran’s narrative.
Ultimately, the question is not whether Iran possesses the capability to escalate further, but whether doing so advances its long-term national interests. Strategic patience, selective deterrence and diplomatic engagement could preserve Iran’s security while minimizing regional backlash. Conversely, broadening the conflict invites counterbalancing coalitions and deepens instability.
Saudi Arabia, for its part, faces a delicate balancing act. It seeks to protect its sovereignty and economic interests without becoming the epicenter of a wider war. Its restraint reflects rational cost-benefit analysis rather than weakness. However, if attacks persist and vital interests are threatened, Riyadh may recalibrate. Such recalibration could take diplomatic, economic or military forms.
The Gulf region stands at an inflection point. Continued escalation risks a spiral that would leave no state unscathed-including Iran. The collapse of fragile regional security would stall development, undermine economic modernization and entrench polarization. Diplomacy remains the only viable off-ramp.
Iran’s leadership must weigh whether short-term displays of defiance justify the long-term costs of isolation and instability. Strategic foresight-not emotional reaction-will determine whether the region moves toward de-escalation or deeper confrontation. The stakes extend beyond national pride or immediate retaliation; they encompass the future security architecture of the Gulf and the prosperity of its peoples.
