When the United States and Israel launched their coordinated assault on Iran in the early hours of February 28, 2026, an operation Washington has named “Operation Epic Fury”, the Gulf states did not cheer.

They watched with dread.

For years, they had invested enormous diplomatic capital in preventing precisely this moment.

They had engaged Tehran, maintained embassies, and offered repeated assurances that their territories would not serve as launchpads against the Islamic Republic.

That Iran’s response has been to turn its missiles on these same neighbours is not only a strategic miscalculation of historic proportions, but is also a profound moral and legal failure that risks poisoning relations for generations to come.

A record of genuine restraint The Gulf Cooperation Council (GCC) states did not arrive at this crisis as Iran’s enemies.

They arrived as reluctant bystanders, having spent years threading a needle between Washington and Tehran with deliberate, often thankless, care.

Saudi Arabia chose dialogue in 2019 and pursued a full diplomatic rapprochement with Tehran.

That process culminated in the landmark 2023 Chinese-brokered normalisation agreement and the reopening of embassies.

Riyadh’s bet was that engagement, not confrontation, was the path to stability.

Even as the current crisis mounted, Saudi Arabia explicitly confirmed to Iranian authorities that it would not permit its airspace or territory to be used to target Iran.

The kingdom’s word was given.

It was not honoured in return.

Qatar had invested years in mediation, serving as the indispensable interlocutor between Hamas and Israel, and between Iran and the United States.

Doha hosted indirect nuclear talks and pleaded for diplomatic solutions when few others would.

Oman, for its part, served as the quiet conduit for the very negotiations that, as recently as the eve of the war, held out the slim hope of a deal.

Oman’s Foreign Minister Badr Albusaidi voiced optimism that peace was “within reach” on the day before the bombs fell.

Across the GCC, governments gave repeated and public assurances to Iran and to the world that their territories would not be used to launch attacks against the Islamic Republic.

These assurances were credible.

They were substantive commitments backed by years of diplomatic engagement.

Iran itself tacitly acknowledged their sincerity: On March 5, Tehran issued a notable public expression of appreciation to Saudi Arabia for upholding its commitment not to allow its territory to be used against Iran.

That acknowledgement makes Iran’s actions all the more contradictory and indefensible.

For these are not the actions of hostile neighbours.

These are the actions of states that understood the neighbourhood they lived in and chose, repeatedly, the hard road of diplomacy.

The response that shocked the region Iran’s response has repaid years of Gulf good faith with a barrage more ferocious than anything directed at the countries that launched the war.

Official statistics show that in the early days of the war, Iran fired more than twice as many ballistic missiles and approximately 20 times more drones at Gulf states than at Israel.

Three people were killed and 78 were injured in the UAE alone; Saudi Arabia’s largest refinery was set ablaze; major airports across the Gulf were targeted; and Qatar’s Ras Laffan, a pillar of global liquefied natural gas (LNG) supply, was struck.

The closure of the Strait of Hormuz, through which a fifth of the world’s oil and a significant share of global LNG passes daily, sent immediate shockwaves through international markets.

Iranian threats of attacks brought commercial shipping through the passage to a near-standstill, severing the artery that connects Gulf energy producers to the economies of Asia, Europe and beyond.

With Saudi, Emirati and Qatari exports frozen in place and insurance markets in freefall, the spectre of a prolonged closure raised alarms not seen since the tanker wars of the 1980s, pushing the world measurably closer to an economic shock that no recovery playbook is designed to absorb.

Illegal, counterproductive and unacceptable Iran’s attacks on Gulf sovereign territory are not merely strategically misguided; they are illegal under international law.

The Gulf states are not parties to the conflict between Iran, Israel and the United States.

They did not authorise military operations against Iran from their soil.

Targeting civilian infrastructure, airports, hotels, refineries and ports in states that are not combatants violates fundamental principles of international humanitarian law, including the prohibition on attacks against civilian objects and the requirement of distinction between military and civilian targets.

Tehran has sought to justify the attacks by arguing that the presence of US military bases on Gulf soil makes....
