The 21 Miles That Hold the World Hostage | 40 Years in the Strait of Hormuz

On the morning of February 28, 2026, American and Israeli aircraft struck Iran in a coordinated campaign called Operation Epic Fury. Within days, Iranian forces had declared the Strait of Hormuz closedת a 21-mile channel between the Iranian coast and the Omani peninsula of Musandam, through which roughly a fifth of the world's seaborne oil had quietly flowed for decades. Gasoline prices in the United States have since risen more than 50 percent. Hundreds of ships sit stranded. And the world watches a game of naval brinkmanship that feels, to many, terrifyingly new.

It is not new. Not even close.

The threat to close the Strait of Hormuz has been Iran's trump card, long before Donald Trump was a presidentת since the 1970s. To understand why the crisis keeps returning, and why it never quite resolves, is to understand something essential about the geography of oil, the paranoia of great powers, and the peculiar pride of a nation that sits astride the most consequential bottleneck on earth.

The geography of leverage

The Strait of Hormuz is a crescent-shaped sliver of water connecting the Persian Gulf to the Gulf of Oman and, beyond it, the Arabian Sea. Iran sits on one shore. Omanת politically neutral and quietly essential, sits on the other. The navigable shipping channels are barely two lanes wide in global terms: two inbound, two outbound, separated by a thin median zone.

This pinch point is why the Persian Gulf matters at all. Strip it away and Kuwait, Qatar, Bahrain, the UAE, and southern Iraq become maritime dead ends. Saudi Arabia's eastern fieldsת the largest conventional oil reserves on earthת lose their only efficient exit. Qatar's liquefied natural gas, which heats homes across Europe and Asia, has nowhere to go.

Iran has always known this. It has lived with this knowledge the way a small nation lives next to a powerful neighbor: carefully, resentfully, and with one hand on the weapon it cannot afford to use but cannot afford to put down.

The tanker war, 1984–1988

The first time the strait became a shooting gallery was during the Iran-Iraq War, a grinding eight-year conflict that killed perhaps a million people and reshaped the Middle East. By 1984, both sides had begun targeting oil tankers, Iraq to strangle Iran's export revenues, Iran to punish Gulf states backing Saddam Hussein's war machine.

By 1987, Iranian mines and Revolutionary Guard speedboats had made the Gulf genuinely dangerous. Kuwait, alarmed, asked both the Soviet Union and the United States to reflag its tankers, a clever move that forced Washington's hand. The Reagan administration agreed, partly from Cold War anxiety about Soviet inroads.

Operation Earnest Will began in July 1987. U.S. Navy warships escorted Kuwaiti tankers through the Gulf in the largest convoy operation since World War II. It was not bloodless. The USS Stark was struck by Iraqi Exocet missiles, killing 37 American sailors, in a friendly-fire incident that America chose not to escalate. The USS Samuel B. Roberts hit an Iranian mine. In retaliation, the U.S. launched Operation Praying Mantis in April 1988, destroying two Iranian oil platforms and sinking several Iranian vessels. It was the largest surface naval battle the United States had fought since 1945.

"The strait has never been just a shipping lane. It has always been a political instrument and Iran has always known how to play it."

Then, on July 3, 1988, the USS Vincennes shot down Iran Air Flight 655, killing all 290 people aboard. Iran called it deliberate murder. The U.S. called it a tragic misidentification. The truth, that a warship crew under stress in a crowded strait fired at what its systems had classified as an attacking fighter, said something uncomfortable about what happens when great navies and small waterways collide. Iran accepted a ceasefire with Iraq two weeks later. Many historians believe the downing of the airliner, and the demonstration that America would fight, was the decisive factor.

The threat becomes ritual, 1990s–2010s

After the Islamic Republic survived the tanker war and the ceasefire with Iraq, the strait settled into a new role: threat theater. Iranian commanders issued warnings about closing Hormuz with such regularity that the statements became almost formulaic. Western analysts began calling it "the Hormuz card" - something Tehran played rhetorically whenever it felt cornered, without ever quite playing it in full.

The pattern was consistent. Sanctions tightened. Iran threatened to close the strait. Oil prices spiked. Diplomats scrambled. Then the crisis eased without anyone having to test whether Iran could actually do what it claimed.

The 2011–2012 standoff was the closest the ritual came to breaking down. The European Union imposed an oil embargo. Iran's parliament debated legislation to block the strait preemptively. The aircraft carrier USS John C. Stennis transited the strait as a demonstration. Iranian state television broadcast speedboat exercises showing swarms of small craft attacking a mock carrier. Both sides blinked, eventually, and the JCPOA nuclear deal, signed in 2015, gave the pattern a longer pause than usual.

But the underlying logic never changed. Iran could not permanently close the strait, doing so would devastate its own economy, since it exports oil through the same channel. What it could do was threaten to close it, impose costs on commercial shipping through mines and harassing tactics, and raise the price of doing business in the Gulf until the political calculus shifted in its favor. This is asymmetric leverage at its most elegant: the ability to impose costs without bearing them equally.

2019: The shadow war

When the Trump administration withdrew from the JCPOA in 2018 and reimposed sanctions, the pattern resumed with new intensity. In the summer of 2019, six tankers were attacked near the strait in circumstances that U.S. officials attributed to Iran. The British-flagged Stena Impero was seized by Revolutionary Guard speedboats and held for two months, a direct echo of the 1980s, updated with drone footage and social media. The U.S. assembled a maritime coalition it called Operation Sentinel. Britain, Australia, and a handful of Gulf states participated. Iran called it provocation. The strait stayed open, barely.

The killing of Qasem Soleimani by U.S. drone strike in January 2020 raised the temperature to its highest point since 1988. Iran launched ballistic missiles at U.S. bases in Iraq. For 72 hours the region held its breath. Then both sides stepped back. The strait remained open.

2026: The card gets played

What is different now, what makes the current crisis something more than another cycle of the ritual, is that Iran has actually done what it previously only threatened. The strait is not technically closed. But with Iranian mines in the channel, Revolutionary Guard boats attacking merchant vessels, and insurance costs making transit economically prohibitive, the practical effect is the same. Pre-conflict, roughly 3,000 vessels used the strait monthly. That figure has collapsed to around 5 percent of normal levels.

The proximate cause, U.S. and Israeli airstrikes that killed Supreme Leader Ali Khamenei, crossed a threshold that previous crises never reached. Iran had signaled for years that an attack on the supreme leader would trigger a response of a different magnitude. It was not bluffing. And so the Hormuz card, played rhetorically since the 1980s, is now being played in earnest, with the global economy as the table.

The irony is that Iran suffers too. Its own oil exports are now blockaded by American naval forces. The Gulf states it relies on for back-channel trade are reeling from drone strikes on their ports and oil facilities. The country that held the leverage has also applied it to itself.

"Iran has the power to wound the world economy through the strait. It does not have the power to survive doing so indefinitely."

This is the fundamental contradiction that has always shaped Hormuz. Iran's leverage is real but self-limiting. America's military superiority is real but strategically insufficient, you can control a strait with warships, as Earnest Will demonstrated, but only if someone is willing to die doing it, and only if the political costs are bearable. Pakistan is mediating. Trump has announced and then paused an operation called Project Freedom. The IRGC has issued statements suggesting passage will be ensured under "new procedures" - a formulation that means everything and nothing.

The view from history

Every generation of policymakers discovers Hormuz as if for the first time. The Reagan administration was blindsided by how quickly a regional war could put U.S. naval assets in the crosshairs. The George W. Bush administration, planning the Iraq War, worried obsessively about the strait as a vulnerability and mostly set those worries aside. The Obama administration used it as a pressure point in nuclear negotiations, betting, correctly, for a while, that Iran would not sacrifice the strait to spite its face.

History suggests a resolution will come. It always has. The economic pain on all sides is simply too severe to sustain indefinitely. Iran knows this. America knows this. The question is what shape the settlement takes, whether the U.S. and Israel achieve the "regime change" they declared as a war aim, whether Iran rebuilds under new leadership with nuclear ambitions intact, and whether the informal international norm that commercial shipping is off-limits in geopolitical conflicts survives the current battering.

What history does not suggest is that the problem will go away. As long as a fifth of the world's oil must pass through a 21-mile channel bordered by a country that resents American power and has built an entire strategic doctrine around the leverage that geography provides, the Strait of Hormuz will remain what it has been since the tanker war: the world's most consequential bottleneck, and its most reliable source of crises.

The ships will start moving again. They always do. And in a few years, or a decade, the crisis will return, because the geography has not changed, and neither, in any meaningful sense, have the politics.
