On the morning of February 28, 2026, American and Israeli warplanes struck Iran in a coordinated surprise attack that killed Supreme Leader Ali Khamenei, shook the Middle East to its foundations, and lit a fuse the world is still watching burn. Six weeks on, the fires have not gone out. But what has been consumed as much as any military target in Iran is something older, more painstakingly constructed, and harder to rebuild: the idea of Western unity.
The United States launched this war without telling its allies. No consultation, no collective deliberation, no nod to the international legal architecture it spent eight decades building. NATO’s most powerful members, France, Spain, Italy, Germany, Poland, learned of the strikes the same way the rest of the world did: through breaking news alerts. And in the weeks since, those same allies have responded not with solidarity but with a rolling, coordinated refusal that has exposed the deepest fracture in the Western alliance since the 2003 invasion of Iraq.
Spain moved first and most decisively, closing its airspace entirely to any American military aircraft involved in the Iran campaign and refusing Washington access to two major jointly-operated bases on its territory. Its prime minister called the war a “big mistake”; its defence minister went further, describing it as “profoundly illegal and profoundly unjust.” Italy followed, denying US bombers permission to land at Sigonella in Sicily, a remarkable act of defiance from a government led by Giorgia Meloni, a Trump ally who has nonetheless found the conflict impossible to endorse. France restricted American flights carrying weapons to Israel from crossing its territory. Poland refused an informal US request to redeploy its Patriot missile batteries to the Gulf. Austria confirmed it had denied all American military airspace requests from the outset. The geography of refusal stretches from the Iberian Peninsula to the Alps.
Trump’s response has been characteristically explosive. He has branded European leaders “cowards” for declining to join the effort to reopen the Strait of Hormuz, the critical waterway through which roughly a fifth of the world’s oil and gas flows, now effectively sealed by Iran as retaliation for the strikes. He has threatened trade reprisals against Spain. He has floated the possibility of withdrawing from NATO altogether. Secretary of State Marco Rubio, sounding less like a diplomat than a man settling accounts, declared that Washington would be forced to “re-examine the value of NATO” once the conflict was over. And when Defence Secretary Pete Hegseth was asked directly whether the United States still stood by Article 5, the mutual-defence guarantee at NATO’s heart, he deferred to Trump before observing that “you don’t have much of an alliance if you have countries that are not willing to stand with you.”
The Europeans, on their part, have a clear and consistent legal argument. NATO is a collective self-defence organisation, they say; it was not designed for offensive wars of choice launched without a UN mandate. “There was no evidence of imminent attack of Iran against the US or Israel,” noted one British analyst. “NATO allies were not consulted.” France’s deputy defence minister made the point in language almost clinical in its precision: “It is not designed to carry out operations in the Strait of Hormuz, which would be a breach of international law.” Even Italy, which has tried hardest to preserve its relationship with Washington, framed its refusal in terms of treaty obligations rather than political hostility. The message from across the continent is unified: this is not our war.
The cruelest dimension of this crisis is the diplomatic wreckage that preceded it. Just one day before the bombs fell, Oman’s foreign minister Badr Al-Busaidi announced that a significant breakthrough had been reached in indirect negotiations with Iran. Tehran had reportedly agreed to halt uranium stockpiling, accept full verification by the International Atomic Energy Agency, and downgrade its enriched uranium to the lowest possible level. Peace, Al-Busaidi said, was “within reach.” Talks were expected to continue on March 2nd. Instead, on March 1st, the world woke to smoke over Tehran. The Omani mediator said he was “dismayed” that “active and serious negotiations” had been undermined. That diplomatic moment, if it ever truly existed, is gone.
Iran’s response has been both military and rhetorical. Its foreign minister Abbas Araghchi insisted his country never requested a ceasefire and was “ready to defend ourselves for as long as it takes.” Iranian drones and ballistic missiles have struck Israel, American military bases across the region, energy infrastructure in the Gulf, and civilian targets in Arab states that host US forces. The Strait of Hormuz, which Iran has largely blocked, has sent global oil and gas prices soaring. The International Energy Agency has estimated that disruptions have cut global supply by around eight million barrels of crude per day. In late March, Iran rejected a fifteen-point American peace proposal and counter-proposed five conditions of its own: a complete end to US-Israeli strikes, compensation for damages, mechanisms to prevent future attacks, and international recognition of Iranian sovereignty over the Strait of Hormuz. Washington found these terms unacceptable. The war continues.
The strategic beneficiaries of this chaos are not in Washington or Tel Aviv. They are in Moscow and Beijing. Russia, with sanctions temporarily eased by a White House distracted by the Middle East, is pumping billions in oil revenue into its war chest as prices surge. Russian state media has greeted every new NATO squabble with barely concealed delight, framing the alliance’s divisions as proof of the West’s internal collapse. A furious Trump has reportedly threatened to cut off weapons supplies to Ukraine through NATO if European allies refuse to help open the Strait of Hormuz, a threat that, if acted upon, would be a gift to Vladimir Putin of almost incalculable value. China watches, and takes notes.
So has the United States been isolated? The honest answer is: not entirely, but more than at any point since the Cold War. Washington retains the world’s most powerful military. It has Israel as a partner and a few Gulf states as tacit collaborators. Around thirty nations are reportedly discussing a “coalition of the willing” to help reopen the Strait of Hormuz once hostilities cease, a formulation that pointedly declines to endorse the war itself. The United Kingdom, agonised and conflicted, has allowed American bombers limited use of its bases for “defensive” purposes while stopping well short of joining the campaign. But the core of what made American power global, the network of alliances, the legitimacy of leadership, the moral authority to ask others to follow, is visibly diminished. A superpower that goes to war without its allies, that threatens those allies when they refuse to follow, and that bombs a country that was hours from a diplomatic agreement, is not projecting strength. It is projecting isolation wearing the costume of force.
The question that haunts every foreign ministry from Paris to New Delhi is what kind of world emerges from all of this once the guns fall silent. The post-war order established after 1945 rested on four pillars: American military primacy, a rules-based international system anchored in the United Nations, a network of mutual-defence alliances, and a commitment to multilateral diplomacy as the first resort rather than the last. Each of those pillars has been under strain for years. The Iran war of 2026 may be the event that accelerates their replacement.
A NATO that has fractured so publicly over one unauthorised war will not easily return to the quiet presumption of solidarity. European nations, already jolted by Trump’s tariff campaigns and his threats against Greenland, are now investing seriously in autonomous defence capabilities and independent foreign policy. The case for European strategic independence, once the preserve of Gaullist theorists, has been made more powerfully by six weeks of American unilateralism than by any academic argument. Whatever the post-war European security architecture looks like, it will be less deferential to Washington.
Across the Global South, the lesson being absorbed is one of confirmation rather than revelation. The rules, it turns out, apply differently to different countries. A war launched without UN sanction, against a country that was negotiating in good faith, by a power that simultaneously threatened its own allies with economic punishment: this is the behaviour of a hegemon in decline, not a guardian of international order. Nations will draw their own conclusions. Some already have.
After the ceasefire, whenever it comes, the world will not simply return to where it was. The Strait of Hormuz will reopen, oil prices will fall, and the most urgent humanitarian crises will slowly recede from the front pages. But the structural damage runs deeper than any single crisis. International law has been weakened by being defied so openly and at such cost. NATO’s mutual-defence guarantee has been clouded by public threats of abandonment. The institutions designed to mediate between great powers have been shown, once again, to be only as strong as the willingness of powerful states to respect them.
What is emerging, for those willing to see it, is a genuinely multi-polar world, not the comfortable multi-polarity of the liberal imagination, in which many powers cooperate under shared rules, but a more turbulent variant in which multiple great powers pursue their interests with diminishing deference to the frameworks that once constrained them. America’s era of uncontested dominance, which arguably ended with the financial crisis of 2008 and the long wars in Iraq and Afghanistan, may now be passing its final milestone. The question is not whether the world will be different after this war. The question is whether any power, or any coalition of powers, will have the legitimacy and the will to build something more stable from the pieces.
From the northeast of India, these events may feel geographically remote. They are not. Energy prices in Shillong reflect what happens in the Persian Gulf. The trade routes on which Indian commerce depends pass through waters now in turmoil. The balance of power in Asia, where China watches American credibility erode with quiet satisfaction, will shape the security environment of every country in the region for decades. The war in Iran is, in its way, a referendum on the post-war world order. And however that referendum resolves, the world that comes after will demand new thinking, new alignments, and a clear-eyed recognition that the certainties of the previous century are no longer available to us.
History’s turning points are rarely obvious in real time. But on a morning in late February, when bombs fell on a city where diplomats had been talking just the day before, something changed. We are still learning the shape of what it was.
