The Iran War Has Remade the Gulf

Before they do, however, they will have to reckon honestly with something that their public statements have carefully avoided: Iran, for all the punishment that it has absorbed, has not lost this war in any strategic sense. That conclusion is uncomfortable, but it is the one that Gulf policymakers are drawing in private.

Consider what Iran demonstrated. It went to war against the United States and Israel simultaneously. It absorbed significant strikes on its nuclear infrastructure, lost senior military commanders, and watched its conventional forces sustain serious damage. And yet it still managed to close the Strait of Hormuz for weeks, cutting off roughly one-fifth of global oil supply. It rained missiles and drones on every GCC state, hitting airports, hotels, and oil infrastructure.

Iran exposed, in the starkest possible terms, the limits of U.S. deterrence as a protective shield for its Gulf partners. For a country operating under decades of sanctions with a defense budget that represents a fraction of what the United States spends in the region in a single year, that is not a conventional defeat. It is a demonstration of strategic resilience that Iran’s neighbors will not forget.

The GCC states are sitting with an equally uncomfortable truth about themselves. Despite hundreds of billions spent on U.S. weapons systems, they could not fully protect their own civilian infrastructure. Iranian drones got through. The Gulf’s carefully cultivated image as a stable investment destination, built over decades and worth billions in foreign capital, has taken a blow that no amount of official reassurance can quickly repair.

Vulnerability, it turns out, is not just a military condition. It is an economic one. And Iran’s instruments of regional power, though degraded, were not dismantled. Hezbollah is battered but not destroyed. The Houthis demonstrated throughout the conflict that they can threaten Gulf shipping lanes with limited means and considerable effect. Iranian influence in Iraq remains largely intact. A weakened Iran that retains its network of influence across the Arab world is a different kind of threat than a strong Iran with a functioning nuclear program. It is in some ways a more unpredictable one.

None of this means that the GCC states will seek accommodation with Iran out of fear. It means that they will seek it out of clear-eyed realism. Tehran is not going away. It shares the Persian Gulf with all of them and has Shiite communities with varying degrees of political salience in Bahrain, Kuwait, and Saudi Arabia’s Eastern Province. The 2023 Chinese-brokered Saudi-Iranian rapprochement gave Riyadh a template for managing Tehran through diplomacy rather than confrontation. That template is not dead, since both sides are now more aware of what the alternative looks like. A failed state on the northern shore of the Gulf, with loose weapons and ungoverned territory, serves no one’s interests. A chastened Islamic Republic with whom one can do business is a far more manageable outcome.

Now turn to the U.S. relationship. Washington went to war without consulting the Gulf states in any meaningful way. They found themselves on the receiving end of Iranian missiles within 48 hours of the Feb. 28 strikes. The message from Tehran was unambiguous: Proximity to U.S. power is not protection. It is a target.

The GCC states will not abandon the U.S. security umbrella. The performance of U.S. missile defense technology during the conflict demonstrated its value in ways that years of sales pitches never could. Expect major new defense procurement agreements and closer military integration in the months ahead. The Gulf states will pull closer to the United States on the hardware of security even as they pull back from the politics of U.S. foreign policy. Future requests for overflight rights, basing access, or diplomatic cover for military operations will be met with far more conditions than before.

The Gulf states watched the United States topple former Iraqi leader Saddam Hussein in 2003 and spend two decades managing the wreckage. They are drawing the same lesson from this war. U.S. military power is real. U.S. strategic follow-through is unreliable. That gap between capability and judgment is precisely why the GCC states have built strong commercial relationships with China, maintained back channels to Russia, and refused to organize their foreign policies entirely around Washington’s priorities.

The question of Israel is thornier. Before Feb. 28, Saudi-Israeli normalization was a slow-moving diplomatic process with significant domestic political costs for Riyadh. The Iran war has reshuffled that deck, but not in the direction that Washington hopes. Israeli missile defense technology performed well during the conflict, and several GCC states now have direct operational experience of Israeli military capability as a force that contributed to their protection.

But Israel itself was vulnerable to Iranian missiles, and the broader Israeli military posture in the region has deepened the political toxicity of normalization for Arab publics. Saudi normalization with Israel remains unlikely, as it will require a credible U.S. commitment to Palestinian statehood. Without that, Crown Prince Mohammed bin Salman has no domestic cover for a deal, and he knows it. U.S. President Donald Trump’s public call for normalization in the war’s aftermath rings hollow.

What emerges from all of this is a Gulf that is more strategically autonomous than at any point in its modern history and more aware of its own fragility than its leaders would ever publicly admit. The GCC states did not choose this war. They absorbed its costs. They watched a regional adversary demonstrate that it could survive a confrontation with the world’s most powerful military and still impose enormous pain on its neighbors. And they watched their primary security guarantor act unilaterally, treating Israeli strategic interests as the organizing principle of a war whose costs fell squarely on the GCC.

The response will not be realignment. It will be a more disciplined, more conditional, and more self-interested foreign policy from governments that have learned, at considerable cost, that no external power can fully substitute for their own strategic judgment. The United States remains the security partner of first resort. China remains the economic partner that no one is willing to alienate. Russia remains a factor in energy markets that the Gulf cannot ignore.

And Iran, however diminished, remains a geographic and demographic reality that requires management rather than elimination. The Gulf states did not invent this approach. They have been practicing it for decades. The Iran war has simply given them more reasons, and more urgency, to trust it.
