The Strait of Hormuz is the point at which approximately one fifth of the world’s traded oil passes through a corridor 21 nautical miles wide, flanked on one side by Iran and the other by Oman. For 70 years, the implicit guarantee that this passage would remain open rested on a single assumption, namely that the United States had both the interest and the willingness to maintain it. The Iran war has exposed what this assumption had long kept from view, that Washington’s willingness to maintain the guarantee has always been contingent on its own stake in the system it is guaranteeing.
On 20 April, Trump posted that Iranian leadership had “forced hundreds of Ships toward the United States, mostly Texas, Louisiana, and Alaska, to get their Oil.” The formulation is analytically significant beyond its rhetorical register. It frames the near closure of a critical energy chokepoint as a condition generating commercial advantage for US producers, one whose resolution is incidental to that advantage. The structural question that formulation raises is how Washington arrived at a position where the disruption of a waterway carrying one fifth of global oil trade could be read as an outcome consistent with its strategic interests. The answer lies in the doctrine that preceded the war, not in the war itself.
The consequences of that question for global energy markets have been extensively documented. The consequences for the architecture of the Western alliance have received considerably less analytical attention. It is the latter question that this piece addresses.
What matters here is not whether Washington planned the sequence of events that followed. What matters is that a doctrine naming specific strategic objectives was already in place when those events arrived, and that the two fit together in ways worth examining carefully.
The strategy took shape in 2025, more than a year before the war began. On 20 January 2025, Trump signed the Unleashing American Energy executive order, establishing what his administration would consistently call Energy Dominance as the organizing principle of American energy policy. A National Energy Dominance Council followed, chaired by Interior Secretary Doug Burgum alongside Energy Secretary Chris Wright, mandated to advise on strategies to achieve dominance across all forms of US energy production and export.
The doctrine has a geopolitical theory embedded in it from the outset, stated with unusual precision in the November 2025 National Security Strategy. The document lists “restoring American energy dominance in oil, gas, coal, and nuclear” as a top strategic priority, and describes the energy sector as one Washington wants to develop as “one of America’s leading export industries in its own right.” On the Middle East specifically, the NSS is unambiguous: the region is losing its historic claim on American attention precisely because “energy supplies have diversified greatly, with the United States once again a net energy exporter.” The guarantee was being withdrawn in the same document that declared the commercial ambition. Energy has been reframed, at least in doctrinal terms, as a strategic instrument rather than a commodity to be managed.
The Iran war and the near closure of the Strait of Hormuz provided the occasion for that ambition to execute at operational scale, without having generated it. Trump’s April statements telling allies to buy American oil or secure the Strait themselves, the subsequent naval blockade of Iranian ports announced on 13 April, and the broader pressure on European and Asian partners to lock in American supply may be read as the convergence of a pre-existing doctrine with a crisis that made its structural logic visible.
The Architecture of Dominance
The material foundation of the doctrine was American shale. By the time the US-Israeli campaign against Iran began in February 2026, the United States was producing more oil and gas than any country in history, exporting both at scale, and drawing far less from the Gulf than at any previous point in the post-1945 period. The Strait of Hormuz has become, from the perspective of American energy supply, a foreign problem, one whose disruption registers in Washington primarily as an inflationary pressure and a diplomatic complication, leaving domestic supply unaffected. That structural autonomy appears to be the precondition any such doctrine requires. A country that still depends on Gulf flows cannot credibly offer to replace them. The contingency appears to have always been present in the guarantee’s structure, obscured for as long as Washington and its allies shared the same material stake in keeping the Strait open. What shale autonomy did was make it visible by removing that shared interest.
The institutional architecture built on that foundation translated that autonomy into operational capacity. Record LNG export permits were issued, federal lands opened at scale, and drilling approvals accelerated by more than fifty percent compared to the preceding period. In 2025, the United States set a historic record by exporting more than one hundred million metric tons of LNG in a single year, the first country ever to reach that threshold. American LNG export capacity, which had been modest in 2022, is on a trajectory to double by 2028. On 4 July 2025, Trump signed the One Big Beautiful Bill Act into law, embedding the doctrine in statute through an Energy Dominance Financing Program providing federal loan guarantees for fossil fuel infrastructure and phasing out clean energy tax credits that had supported competing technologies. A future administration would need congressional action to reverse it.
The NSS simultaneously preserved a narrower Middle East interest: preventing any adversarial power from dominating “its oil and gas supplies, and the chokepoints through which they pass.” This is a materially different commitment from the Carter Doctrine’s guarantee of open access for all. It commits Washington to denying rivals control of the Strait, a narrower and more self-interested obligation than guaranteeing its openness for allies. The blockade announced on 13 April may be read as the operational expression of that distinction.
The National Defense Strategy published in January 2026 operationalized the withdrawal half of that equation. Secretary Hegseth stated explicitly that Washington would “no longer make up for allied security shortfalls from their leaders’ own irresponsible choices.” The terrain Washington committed to guarantee was the Panama Canal, Greenland, and the Gulf of America. The Persian Gulf did not appear among them. The doctrine names adversaries as its primary targets. What it does to allies may prove the more structurally consequential question. The two dimensions are complementary. The doctrine targets adversaries through the elimination of alternative supply nodes and produces, as a structural consequence whether or not by intent, a dependency among allies toward the supply that remains. They are opposite faces of the same logic: who controls the supply controls the dependency, whether the target is an adversary being cut off or an ally being drawn in.
How far that consequence extends depends on variables the doctrine does not control. European governments retain the capacity to diversify toward alternative suppliers. Gulf producers have strong incentives to find routes that bypass American commercial terms. Asian buyers, whose energy dependency is acute, bring bargaining power of their own. The doctrine created conditions for American centrality. Whether those conditions solidify into durable structural leverage is a question the current crisis has opened but not resolved.
The Decoupling Sequence
Tracing how far that configuration extends requires examining the sequence of supply dislocations that preceded the war, each of which happened to narrow the field of alternatives that the doctrine’s own stated goals required narrowing. The three phases operated through different mechanisms. The Russian decoupling removed a competing supplier from European markets. The Venezuelan intervention added a node under American political influence. The Hormuz closure disrupted a transit route on which both suppliers and buyers depend. Different in mechanism, the three phases share a directional effect: each narrowed the alternatives through which Western allies could reach energy outside American influence. The sequence resulted in that effect, each phase removing one viable alternative until the American offer arrived as the residual architecture of a system that had been progressively simplified.
The European phase began with Russia. The invasion of Ukraine in February 2022 triggered a sanctioning of Russian pipeline gas that had, by the mid-2020s, reduced Russian energy flows to Europe from roughly forty percent of continental gas supply to a fraction of that. The political consensus that made European dependence on Russian energy acceptable had collapsed along with the invasion itself. European governments diversified toward Norwegian, Algerian, and American suppliers. The United States moved decisively into that opening, and by 2026 had become the EU’s largest LNG supplier, accounting for well over half of EU LNG imports. The decoupling from Russia has been traumatic and expensive for Europe, and remains commercially advantageous for Washington in roughly equal measure.
The European decoupling from Russian gas had created demand that American LNG was positioned to fill, and the question of whether a comparable dynamic could be engineered on the oil side may find part of its answer in Venezuela. Following a US military operation that removed Nicolás Maduro from power in January 2026, Washington moved rapidly to open Venezuelan crude to international markets under conditions that kept American political control over the proceeds intact. Venezuelan oil re-entering the market under conditions shaped by American political decisions adds a further node to the supply architecture over which Washington exercises partial and conditional influence, and that alignment with the doctrine’s objectives is at minimum worth noting.
The Venezuelan case is worth distinguishing from the Russian decoupling. The Russian phase was a structural realignment triggered by an adversary’s aggression, with American commercial advantage emerging as a consequence. The Venezuelan phase involved direct American military and political intervention in a supplier state, with Washington explicitly assuming control over the proceeds of oil sales. That distinction matters analytically: it suggests that at least one phase of the sequence moved beyond the convergence of doctrine with independent events toward something closer to the active construction of supply conditions. The broader argument advanced here does not require this to be true of all three phases. A consistent directional effect across phases of different character is sufficient to establish the structural point.
The third and most acute phase is the Hormuz closure itself, which has converted the accumulated supply vulnerability into an immediate emergency. The near closure of the Strait since late February 2026, Iran’s selective permission of passage for ships from China, Russia, India, Iraq, and Pakistan, and the war-risk insurance shock that froze much of Gulf shipping have produced the kind of supply emergency that makes Trump’s offer structurally compelling. European allies facing fuel shortages, Asian importers navigating a suddenly fragmented supply landscape, all of them arrived at April 2026 having already lost Russian pipeline gas and finding American production as the most immediately available substitute. The structural damage to Qatar’s position amplifies that substitution dynamic considerably. Iranian strikes on the Ras Laffan LNG complex in mid-March reduced Qatari LNG production capacity by approximately seventeen percent, with repairs estimated to require three to five years. The removal of Qatar as a near-term competitive alternative to American LNG supply may prove among the most structurally durable consequences of the crisis, persisting well beyond any ceasefire or diplomatic resolution.
The Russian decoupling was a response to an invasion, Venezuelan developments a consequence of a US military intervention, and the Iran war initiated for reasons that had little to do with energy market restructuring. The cumulative effect nonetheless produces a supply landscape whose configuration aligns with the doctrine’s objectives: alternative nodes have contracted, American supply has become the most available substitute, and the disruption has arrived at a moment when the substitution offer is most credible. Whether the doctrine shaped the sequence or simply found itself well-positioned within it is a question the available evidence cannot definitively resolve. What it can establish is that a strategy whose declared objectives align with the structural configuration the sequence produced has been in active operation throughout.
The Transaction and the Blockade
Whatever the degree of intentional coordination, the political expression of that structural position took a specific and analyzable form. Trump’s April statements bundled three distinct operations into a single declaration. Allies who declined to join the coalition were told simultaneously that they had forfeited American protection, that American oil was available for purchase, and that the Strait was their problem to solve. These three elements were presented as consequences of the same decision, but they also functioned as a single commercial proposition, in which the security guarantee foregone through non-participation is replaced by an energy relationship paid for through market purchase.
The logic that emerges from this bundled operation is that of the invoiced alliance reaching its most explicit operational form, a concept that captures something the market analysis of energy dominance consistently misses: that the primary casualty of the doctrine is the ally’s structural autonomy, the consequence that tends to be overlooked in the focus on adversarial supply chains. Security provision and energy supply tend toward collapse into a single commercial relationship, and the cost of non-participation is denominated in market dependency, a currency more durable and less reversible than political estrangement.
The transactional framing captures an important dimension of the arrangement, though it reaches only its political surface. Beneath it lies what appears to be the doctrine executing through the crisis. A closed Strait creates pressure toward the American alternative, though the speed and completeness of that substitution depends on variables Washington does not fully control, among them European political will, the pace of infrastructure buildout, and the willingness of Gulf producers to find workarounds of their own. France’s refusal to permit overflight of military supply flights to Israel, Spain’s closure of its airspace to US operations, Britain’s publicly stated refusal to join the coalition, all of these positions may become more difficult to sustain if the energy dependency deepens and the American offer hardens from a wartime measure into a structural baseline. European governments have shown considerable capacity to absorb American pressure without altering their fundamental postures, but that capacity has limits that energy dependency, if sustained, would test.
The structural logic of that position receives its most direct official articulation at a Pentagon briefing on 24 April, when Secretary Hegseth tells reporters that Europe needs the Strait of Hormuz considerably more than the United States does and should consider, in his words, doing “less talking,” having “less fancy conferences,” and getting in a boat. The statement comes from a cabinet official speaking on the record in the context of announcing a blockade expansion, which gives it a different register from the April 20 Truth Social post, doctrinal in character where the post was rhetorical. What it expresses is worth examining in the terms this piece has been developing: Washington repositioning the Strait as a European problem at the same moment it positions itself as the indispensable alternative to the supply that flows through it. The announcement by Macron of a multinational mission to restore freedom of navigation, convening military planners from more than thirty countries in the days following the blockade declaration, may be read as the first institutional response to exactly that repositioning, and is consistent with what the dependency argument would predict as the eventual response of governments whose supply autonomy is under structural pressure.
The naval blockade of Iranian ports announced on 13 April added a further dimension that the transactional framing alone cannot capture. Washington moved to control the Strait as a belligerent, displacing the guarantor role it had previously occupied, on terms entirely its own. The supplier and the gatekeeper converged in the same actor. That convergence is contingent on sustained military presence and political willingness to enforce. Should Washington withdraw from the Strait militarily, the gatekeeper role dissolves even if the supplier role persists. The two dimensions of the convergence carry different durability horizons. A ceasefire agreed on 8 April had briefly reopened the Strait to partial traffic before collapsing in Islamabad over the weekend of 12 April, where twenty-one hours of US-Iran talks failed to produce an agreement. On 18 April, Iran closed the Strait again in response to the US refusing to lift its naval blockade. An Atlantic Council analysis published weeks before the blockade noted that energy dominance appeared to be evolving from a production policy into something broader, involving “control over energy assets, strategic chokepoints, and the global energy flow.” The blockade lent considerable weight to that reading. The doctrine had found its most aggressive operational expression, moving beyond the offer of an alternative to Hormuz dependency toward the active determination of whether the Strait functions at all, for whom, and at what price.
The System That Emerges
The post-1945 energy security architecture rests on a specific distribution of roles, with the United States as guarantor of open sea lanes, Gulf producers as the primary source of global marginal supply, and Western allies as consumers whose access is protected by American military commitment without requiring reciprocal energy dependency on Washington itself. That separation between the military and commercial dimensions of the relationship gives allies significant structural autonomy. The architecture being constructed in its place concentrates both dimensions in Washington simultaneously, tending to collapse the separation into a single relationship in which Washington increasingly sits upstream of both supply and security.
Whether that concentration proves durable is a different question. Iran retains the capacity to complicate Gulf flows beyond the immediate military campaign. Gulf producers have strong incentives to work toward a reopening of the Strait on terms that do not run through American commercial logic. European governments will invest in diversification. Diversification, if sustained, would erode the positional argument more directly than any other counter-pressure, since positional centrality derives from being the node through which flows must pass, a condition that production volume alone cannot create. A successful European diversification away from American supply would reduce Washington’s structural position even if American production volume remained dominant. The American offer is a crisis solution, and crisis solutions tend to carry within them the conditions of their own erosion. Political will to avoid repeating a painful dependency tends to outlast the crisis that revealed it, which means Washington’s ability to translate energy centrality into sustained political leverage may prove considerably narrower in duration than the structural argument suggests.
The constraint that qualifies that centrality is infrastructural rather than strategic. American LNG export terminals are already running at near-full capacity, and new facilities take years to permit and build. The offer of substitution is credible as a long-term proposition and as a geopolitical signal, but its immediate delivery capacity is finite. Washington’s ability to translate doctrinal ambition into physical supply at the scale the crisis demands remains bounded by the infrastructure the doctrine has not yet had time to complete.
These constraints qualify the doctrine’s reach and leave its logic intact. The position Washington now occupies was assembled through shale investment, sanctions architecture, alliance management, institutional design, and a war whose energy consequences may outlast its military ones by a considerable margin. What distinguishes the current moment from previous episodes of American energy advantage is that the advantage has acquired a doctrinal character, actively named, institutionally constructed, and operationally pursued. Trump’s offer to sell oil to the allies who declined to fight is, in that longer frame, consistent with the logic of a pre-existing doctrine, one whose operational expression the crisis made possible without having generated. The United States is repositioning itself from systemic guarantor to indispensable supplier, a role that generates revenue where the previous one generated only obligation, and that converts the dependency it once protected others from into a dependency directed, whether by design or structural convergence, toward Washington itself.
