One Does Not Simply Close the Strait
Iran spent forty years building the architecture to hold three of the world’s critical maritime chokepoints. Here is what that architecture actually was, what happened to it, and why it matters more t
Written May 2026. This is the third piece in a sequence. The tribal reversal that set everything in motion is in When the Team Matters More Than the Strategy. The intellectual framework connecting all of it to Zeihan’s structural predictions is in The Accidental Superintendent. The Ukraine side of the argument is in The Best Deal Nobody Wanted to Make. The China piece that ties all four together is coming Friday.

In Tolkien’s mythology the three elven rings were not rings of conquest. They were rings of control, forged to preserve order and maintain leverage over the world’s most critical domains. The one ring did not destroy what the three rings protected. It controlled the power behind them. Iran’s regional strategy for the last forty years operated on exactly that principle. Three proxy networks. Three chokepoints. One state sponsor holding the thread that made all three functional simultaneously. You did not need to understand Iranian foreign policy to understand the architecture. You just needed to look at the map.

Around ninety percent of the world’s traded goods travel by sea, and that trade does not flow freely across open ocean. It funnels through a handful of narrow gaps in the geography where the entire global economy becomes vulnerable to whoever controls the approaches. There are roughly two hundred straits worldwide but only a handful function as true chokepoints, passages so narrow and so strategically positioned that disrupting them ripples across energy markets, supply chains, and food security within days.
The Strait of Hormuz sits between Iran and Oman at its narrowest point, a twenty-one mile gap that is the only maritime outlet for five of the world’s top ten oil producers. Roughly twenty percent of global petroleum consumption transits through it daily, approximately twenty million barrels, along with thirty percent of the world’s liquefied natural gas exports. There is no bypass route. When Hormuz is disrupted, the disruption is total for every ship that needs to get in or out of the Persian Gulf. China imports roughly seventy percent of its energy needs, and approximately forty percent of that passes through this gap. For Beijing, Hormuz is not an abstraction about Middle Eastern politics. It is the artery the entire Chinese economy depends on staying open.
The Bab el-Mandeb sits at the southern entrance to the Red Sea, an eighteen mile wide passage between Yemen and Djibouti that every ship traveling between Asia and Europe via the Suez Canal must pass through. Approximately twelve percent of global seaborne trade by value transits this corridor annually, roughly nineteen thousand vessels per year, including four point eight million barrels of oil per day. When the Houthis closed it to certain shipping in 2023, container rates from Shanghai to Rotterdam jumped one hundred fifty eight percent and major carriers rerouted around the entire African continent, adding ten to fourteen days to voyages.
The Eastern Mediterranean approaches to the Suez Canal represent the third leg of the architecture. Hezbollah’s missile arsenal and tunnel networks in southern Lebanon gave Iran a credible threat against Israeli energy infrastructure and Eastern Mediterranean shipping that functioned as a strategic deterrent against Israeli and American action in ways that neither the Houthis nor the Revolutionary Guard could provide from the Gulf alone.
Three chokepoints. Three proxy networks. One sponsor. Iran spent approximately one to two billion dollars annually maintaining this architecture, with Hezbollah alone receiving an estimated seven hundred million to one billion dollars per year covering fighter salaries, social services, weapons procurement, and infrastructure. The Houthis received one hundred to two hundred million annually in direct transfers plus weapons. Iraqi militia networks received the rest. Every dollar of that investment was paying for the same thing, the credible threat that any American military action against Iran would cost the global economy in ways that would generate political resistance to that action before it could achieve its objectives.
Iran’s funding model was not charity for allied militias but a distributed deterrent system built by professionals who understood that a country with conventional military limitations could only deter a superpower through cost imposition at scale, and the chokepoints were the mechanism through which Iran could impose those costs on the entire global economy simultaneously rather than just on the countries directly involved in the conflict.
For forty years it worked.
Operation Epic Fury launched February 27 to 28, 2026. Joint American and Israeli strikes targeted Iranian nuclear facilities, military infrastructure, and leadership simultaneously. Khamenei was killed in the opening strikes. Over two hundred and eighteen strikes were recorded across Iran, Lebanon, Yemen, Iraq, and the Gulf across forty days of sustained operations. The ceasefire took effect April 8. The two month campaign cost the United States approximately $25 billion and depleted critical munitions stockpiles at rates analysts assessed would take three to five years to rebuild.
The failure narrative that dominates most current coverage rests on three observations that are accurate as far as they go. The regime survived and is if anything harder line. Iran’s missile and drone production capacity was degraded but not eliminated, and markets have not yet adjusted to what Japan’s April 21 arms export reversal and Ukraine’s two hundred plus emerging drone companies mean for the long-term strategic value of the asset Iran just partially lost. The proxy networks, Hezbollah’s tunnel infrastructure, the Houthi missile capability, Kataib Hezbollah’s embedded position in the Iraqi security apparatus, were damaged but not destroyed. The underground missile city network, featuring redundant exits, decoy entrances, and mobile launchers that could emerge, fire, and return underground, meant no air campaign could fully disarm Iran’s retaliatory capability. US intelligence undercounted Iran’s missiles by more than one thousand.
The argument here is not that the Iran problem is solved. It is that the deterrent failed, which is a different and more important observation. The distinction matters and it is worth stating plainly before moving past it.
A deterrent does not have to be destroyed to fail. It has to fail to deter. Iran’s entire strategic architecture was built around the proposition that the cost of military action against it would be so high, in disrupted energy markets, in proxy attacks on American bases, in Houthi Red Sea interdiction, in Hezbollah missile barrages, that no American administration would absorb those costs to achieve the strategic objectives that military action might produce. The architecture performed. Iran closed Hormuz on March 4. The Houthis resumed attacks. Hezbollah fired barrages into northern Israel. Iranian ballistic missiles hit American bases in the UAE, Qatar, and Bahrain.
And the strikes happened anyway. Forty days of them.
The deterrent did not prevent the action it was designed to prevent. Iran is now sitting across a negotiating table discussing the removal of its enriched uranium stockpile, a moratorium on enrichment, and the reopening of the Strait of Hormuz, a conversation happening not because Iran chose to have it but because the architecture that was supposed to prevent it from being necessary failed to do its job. The current deal being negotiated is meaningfully different from the JCPOA in one structural way that matters more than any of the specific terms. The JCPOA left Iran’s enriched uranium inside Iran on a sunset timeline, betting that temporary constraints would hold long enough for something else to change. The current negotiation is about physically removing that material. Whether Iran ultimately agrees to removal is still being contested, but the fact that removal is on the table at all is evidence of a negotiating position the JCPOA’s architects never achieved.
The negotiations themselves are being contested in real time in ways that illustrate exactly how the deterrent failed without producing a clean resolution. On May 25, while Iranian political leadership was participating in negotiations and Pakistani mediators were shuttling between capitals, IRGC boats were caught laying mines in the Strait of Hormuz and an IRGC surface-to-air missile site in Bandar Abbas was actively targeting American aircraft. CENTCOM conducted self-defense strikes eliminating both mine-laying vessels and striking the SAM site. Iran’s foreign ministry responded by accusing the United States of a clear violation of the ceasefire and bad faith. The IRGC, whose boats were laying mines during a ceasefire, was not mentioned in that statement.
This is the conflict’s defining dynamic in one paragraph. Iranian political leadership negotiates. The IRGC provokes. American forces respond. Iranian political leadership accuses Americans of bad faith for responding to IRGC provocations. The IRGC gets to continue its operational campaign while political leadership maintains negotiating credibility by condemning American responses to that campaign. It is a useful arrangement if you are Iran and you want to preserve leverage while appearing to negotiate in good faith. It is considerably less useful if you are trying to understand what is actually happening from the outside.
The current state of Hormuz is the most vivid illustration of what deterrence failure looks like in practice. On May 16, Iran confirmed it would unveil a transit toll mechanism for the strait administered by the newly established Persian Gulf Strait Authority. Vessels must apply disclosing ownership, insurance, crew manifests, and cargo before being granted a transit permit. Reports indicate vessels have paid up to two million dollars per transit settled in Chinese yuan, with Bitcoin payments to IRGC-linked wallets also accepted to bypass Western banking infrastructure. India, Iraq, and Pakistan secured bilateral carve-outs outside the formal fee structure while Western-aligned tonnage is either frozen out or subject to interdiction.
The partial blockade that created this situation deserves honest examination because it is the clearest strategic fumble of the post-conflict period. Chokepoint control is binary. You either control it or you do not, and partial control hands your adversary the administrative vacuum it needs to institutionalize whatever leverage it retains. The moment the United States signaled exceptions, Iran stopped being the party that closed the strait and became the party that administers it, which is a fundamentally different and more durable form of leverage because it generates revenue, creates bilateral dependencies with India and China, and requires a second round of American pressure to dislodge rather than simply holding the line.
A wounded state charging two million dollars per ship in Chinese yuan through an email address, because it can no longer credibly threaten to close what it is now trying to govern, is not a superpower administering a strategic waterway. The toll regime is the deterrent rebranded as a toll booth, and the current negotiations are specifically about removing that toll booth and restoring freedom of navigation under American terms rather than Iranian administrative control.
The Accidental Superintendent strikes again.
China’s President Xi Jinping sat across from Trump in Beijing on May 15 and told him that the Strait of Hormuz must remain open and free of tolls, that China would stop supplying military equipment to Iran, and that China would help pressure Tehran toward a deal. Then Trump announced that China had agreed to buy American oil, with Chinese tankers heading to Texas, Louisiana, and Alaska. China has not formally confirmed the energy purchase agreement and the details remain to be finalized, but the direction of the negotiation is not ambiguous. The country whose entire economic model depends on energy flowing through Hormuz just told the country that controls the military situation around Hormuz that it would like to buy that country’s oil instead.
American Energy Secretary Chris Wright explained the strategic logic in six words. This is a card you can play once.
Iran spent forty years and tens of billions of dollars building the deterrent architecture that was supposed to give it permanent leverage over the global energy system by threatening the chokepoints that China’s economy depends on. The theory was that Chinese dependency on Iranian-controlled chokepoints would give Tehran diplomatic and economic protection from American pressure. It worked until it did not. Iran played the card. The result is China buying oil from Texas.
The UAE read the same situation and on April 28, two months into the conflict, announced it was leaving OPEC and OPEC+ effective May 1, depriving the cartel of its third largest producer and one of its few remaining swing producers. That defection did not happen in isolation. Gulf supply was constrained by the Hormuz disruption, driving prices higher. American shale, the marginal producer with no exposure to the conflict, was the primary beneficiary of every barrel the Gulf could not move. Ukraine’s drone strikes were simultaneously hitting Russian Baltic export infrastructure, removing a second major competing supply source from global markets. The UAE breaking with the Russian-aligned cartel to position itself to pump more oil into global markets when Hormuz reopens under American-negotiated terms was a business decision driven by the regional security architecture the Abraham Accords created, producing exactly the outcome Iranian deterrence was designed to prevent.
Zeihan’s Winners and Losers of the Iran War series identified North American energy as the structural winner of the entire conflict. Persian Gulf exports constrained. Russian Baltic export infrastructure struck by Ukrainian drones. OPEC weakened by member defection. China negotiating to buy American crude. The United States, the world’s largest oil producer at twenty-one to twenty-three million barrels per day, is the only major energy producer that entered this conflict with geographic insulation from its consequences and emerged with its primary strategic competitors either weakened, dependent, or both.
None of that was the plan. The administration that initiated Operation Epic Fury did not have a published strategy document explaining how degrading Iranian chokepoint leverage would drive China toward American energy purchases, weaken OPEC’s coordination capacity, pull a major Gulf producer out of the Russian-aligned cartel, and force Iran to the negotiating table on American terms. The Accidental Superpower predicted the structural conditions. The Accidental Superintendent stumbled into fulfilling them.
The honest complications deserve acknowledgment before this piece closes. The proxy networks survived. The partial blockade created the administrative vacuum Iran is now filling with the toll regime. The IRGC and political leadership are running parallel tracks during negotiations, with the IRGC laying mines and activating SAM sites while political leadership claims American responses to those provocations are ceasefire violations. The munitions depletion is real and the three to five year rebuild timeline is a genuine strategic cost that does not appear in any victory narrative. The current deal being negotiated notably leaves ballistic missile limits, proxy network funding, and the most demanding nuclear dismantlement requirements for later negotiations, meaning the interim agreement is significantly less than maximum American demands. Iran’s foreign ministry has said enriched uranium will under no circumstances be transferred anywhere despite Trump’s public claim that Iran agreed to removal. The execution had real problems and the final accounting of what the operation achieved versus what it could have achieved with more coherent post-conflict planning is a legitimate question serious analysts are still working through.
What is not legitimate is describing the deterrent that failed to deter as a success, or the country now negotiating at a table it never wanted to sit at as the strategic winner of this exchange. Iran played its one card. The card did not work. The table it is sitting at right now is the evidence.
The next piece in this sequence is about China specifically, about the closing demographic window, the damaged Russian backstop, the energy vulnerability that just became real in ways no strategic analysis could have made it, and the question Zeihan posed recently that nobody in the current coverage is answering directly. The stars appear to be aligning for China to make its move on Taiwan. There is one big issue. Energy.
That piece is next.
