The Shield That Europe Won't Raise: Why the Gulf Cannot Wait for Western Legal Consensus

In December 2017, a ballistic missile launched by Houthi forces in Yemen crossed 900 kilometres of airspace before Saudi Arabia's Patriot defence batteries intercepted it over the outskirts of Riyadh. The missile, a Burkan-2H variant, carried an Iranian design lineage that UN investigators would later confirm. The target was King Khalid International Airport. Had the interceptor missed, the warhead would have struck a civilian terminal in a city of eight million people.

That evening, no European foreign minister issued a statement condemning the attack. The UN Security Council did not convene an emergency session. In Riyadh, the silence confirmed what Gulf security establishments had already concluded: when it comes to the Iran threat, the Gulf is operationally alone.

The Threat Map That Surrounds the Peninsula

For readers in Riyadh, Abu Dhabi, Doha, Manama, or Kuwait City, the geography of the Iran threat requires no explanation. It is the map they live inside.

To the east, Iran's IRGC Navy maintains fast attack craft, coastal cruise missile batteries, and mine-laying capacity along the Strait of Hormuz. Bandar Abbas sits less than 200 kilometres from Dubai. The IRGC routinely conducts exercises simulating the closure of the strait, through which roughly 20 percent of the world's oil supply passes every day.

To the south, Houthi forces in Yemen have weaponised the Bab el-Mandeb chokepoint. Since November 2023, Houthi units have attacked more than 100 commercial vessels with cruise missiles, anti-ship ballistic missiles, and drones supplied by Iran. Red Sea shipping traffic has dropped sharply, with major carriers diverting around the Cape of Good Hope, adding weeks and billions of dollars in costs to global trade. Jeddah's port, Saudi Arabia's primary Red Sea gateway, has seen direct commercial impact.

To the north, IRGC-aligned militias embedded within Iraq's Popular Mobilisation Forces operate along the Iraqi-Saudi and Iraqi-Kuwaiti borders. In Syria, Iranian-backed forces maintain positions that extend Tehran's military reach to within striking distance of Jordan and, through Hezbollah in Lebanon, to the Mediterranean.

The Arabian Peninsula sits inside a ring of Iranian-supplied or Iranian-directed military capability. This is not an intelligence assessment. It is a map.

Moscow's Contribution: The Veto and the Shield

Iran's proxy architecture predates the Moscow-Tehran axis. What Russia added is the strategic ceiling that prevents international institutions from dismantling it.

Russia's role operates on two tracks. The first is diplomatic: consistent use of its UNSC position to obstruct or weaken resolutions that would impose consequences on Iran's weapons proliferation or its proxies' military operations. In early 2024, when Western states sought a UNSC resolution condemning Houthi attacks on Red Sea shipping, Russia abstained and pushed amendments designed to dilute the text. When European and American diplomats pushed for tighter enforcement of arms embargoes against the Houthis, Moscow provided the shield.

The second track is military-technical. Russia completed delivery of S-300 air defence systems to Iran in 2016, significantly complicating any future air campaign against Iranian nuclear or military facilities. The comprehensive strategic partnership treaty signed by Moscow and Tehran in January 2025 formalised a relationship that had already moved beyond transactional arms sales into structural integration: co-production of drones, shared sanctions-evasion networks using shadow tanker fleets, and coordination on energy market strategy.

For Gulf security planners, the Russian dimension transforms a regional threat into a geopolitical structure. Before Moscow's deepening alignment, international isolation of Iran remained theoretically possible. After the 2025 treaty, it is not.

The Abraham Accords: Building What the UN Cannot Deliver

The Abraham Accords, signed in the autumn of 2020, are routinely described in Western media as a peace agreement between Israel and Arab states. In the Gulf, the framing is different. The Accords are a security architecture built on the recognition that the UN Security Council will not contain Iran and that the United States' commitment to Gulf defence, while still substantial, can no longer be assumed to be permanent.

The UAE announced its normalisation agreement with Israel on 13 August 2020, with both the UAE and Bahrain formally signing at a White House ceremony on 15 September. Within a year, the two states had established intelligence-sharing arrangements with Israel, conducted joint military exercises, and begun integrating early-warning systems for missile defence. For Bahrain, which hosts the US Fifth Fleet barely 200 kilometres from Iran's coast, the Israeli connection added a layer of signals intelligence and missile-tracking capability that no European ally had offered.

Saudi Arabia's path toward a similar arrangement has followed a more complex trajectory. The Gaza war interrupted the public timeline, but Riyadh's underlying interest in a defence relationship with Israel has not diminished. The logic is straightforward: Iran threatens Saudi territory directly, and Israel possesses the most advanced missile defence and intelligence capabilities in the region. The Abraham Accords formalised what Gulf states had quietly pursued for years.

Iran condemned the Accords as a betrayal of the Palestinian cause, a framing designed to delegitimise the arrangement within the Arab world. Gulf governments received the condemnation as confirmation that the architecture was working.

The Aramco Lesson

On 14 September 2019, a coordinated strike of drones and cruise missiles hit the Aramco processing facilities at Abqaiq and Khurais in eastern Saudi Arabia. The attack temporarily shut down approximately 5.7 million barrels per day of Saudi oil production, roughly half the kingdom's output and about 5 percent of global supply. It was the single largest disruption of oil infrastructure since Iraq set Kuwait's oil fields on fire during the 1991 Gulf War.

Saudi, American, and European investigators attributed the attack to Iran. Tehran denied involvement. The Houthis claimed responsibility, but the weapons' trajectory, range, and sophistication exceeded Houthi capability without direct Iranian support.

The international response was measured. The United States reinforced its military presence in Saudi Arabia. European governments expressed concern. The UN Security Council did not impose new sanctions on Iran. No military retaliation followed.

In Gulf capitals, the Aramco attack became the defining reference event for a generation of security planning. It demonstrated three propositions simultaneously: that Iran could strike critical infrastructure deep inside Saudi territory; that the international community would not respond with force; and that the legal frameworks governing military action, the same frameworks that European leaders invoke as constraints on strikes against Iran, functioned in practice as a shield for the aggressor.

Why European Hesitation Is a Gulf Security Problem

When Germany's President Steinmeier describes strikes against Iran as contrary to international law, Gulf diplomats hear a specific message: Europe will not act, and it will discourage others from acting. Israel's Ambassador Prosor framed this as "a dream for the Moscow-Tehran axis." In Riyadh and Abu Dhabi, the assessment is less rhetorical but structurally identical.

European hesitation creates a compounding problem for Gulf security. First, it reduces the diplomatic pressure available to constrain Iran's nuclear programme, which Gulf states view as an existential threat. Second, it signals to Iran that proxy operations, from Houthi shipping attacks to IRGC militia deployments, will not trigger a Western military response. Third, it undermines the coalition logic of the Abraham Accords by suggesting that a key bloc of Western states will not support the defensive posture the Gulf is building.

Gulf states do not expect Europe to launch strikes against Iran. What they expect, and increasingly doubt, is that European capitals will refrain from actively obstructing the security arrangements that Gulf states are building for themselves. The legal debate in Berlin, Paris, and Brussels may be internally coherent. From the Gulf, it looks like a continent arguing about the fire code while the building next door burns.

The Same Network, Two Theatres

There is a final dimension that Gulf security establishments watch with close attention: Iran's operational presence on European soil. The 2018 bomb plot planned by Iranian diplomat Assadollah Assadi against an MEK opposition rally near Paris, for which he was convicted by a Belgian court in 2021, the IRGC-linked surveillance cells tracked by Dutch and German intelligence services, the years during which Hezbollah maintained financial and operational infrastructure across Europe with minimal enforcement: these episodes confirm that the Gulf and Europe face the same threat actor.

The difference is calibration. Gulf states have structured their entire foreign and defence policy around the Iran threat. Europe is still debating whether to classify it as one. Gulf intelligence services have cooperated with European counterparts on Iranian operational networks for years, often providing the initial leads that European agencies then investigated. The information flows. The response gap persists.

For the Gulf, the Moscow-Tehran axis is not a phrase in a diplomatic dispatch. It is the strategic environment they navigate every day, from the tanker routes through Hormuz to the missile trajectories over their cities. The question is not whether the axis poses a threat. The question is whether anyone beyond the Gulf's own security architecture will help contain it.
