The latest US-Iran escalation is revealing something more consequential than another exchange of missiles and drones: the Strait of Hormuz is increasingly becoming the operational center of gravity of the war.

On September 1, the United States struck Iranian military infrastructure, including radar systems and other assets associated with Iran’s ability to detect and target shipping. Iran responded by attacking US and allied bases and assets across the region. The exchange represented another dangerous escalation in a conflict that has increasingly moved beyond conventional strikes on military facilities toward a contest over maritime access, energy flows, and the credibility of Iranian control over one of the world's most important waterways.

The significance of the American strikes lies not simply in what Washington destroyed, but in what it appears to have understood about Iran's strategy. Tehran does not necessarily need to close the Strait of Hormuz completely to extract strategic value from it. It can threaten individual vessels, create uncertainty about navigation, force shipping companies to alter routes, raise insurance costs, disrupt tanker movements, and demonstrate that commercial traffic cannot move freely without accounting for Iranian military capabilities.

That is precisely why the latest US strikes against Iranian radar infrastructure matter.

The emerging contest is becoming a struggle between Iranian attempts to find and threaten ships and American efforts to degrade the sensors, launchers, mines, communications systems, and other capabilities that allow Tehran to turn geography into coercive power. The war is therefore evolving from a contest over territory into a contest over the ability to observe, target, and control movement through a maritime chokepoint.

This development reinforces the argument made in my earlier analysis, “The Future of the Strait of Hormuz: Can Iran Institutionalize Control Over the World’s Most Strategic Maritime Chokepoint?”, that Tehran's strategic objective may be more sophisticated than simply announcing a formal closure of the strait. The real prize may be the ability to make navigation conditional on Iranian military and political calculations.

America Is Attacking the Architecture Behind Iranian Maritime Pressure

The US strikes on Iranian radar systems suggest that Washington is increasingly targeting the architecture that makes Iranian maritime disruption possible.

According to the Institute for the Study of War and the Critical Threats Project, the September 1 US strikes appeared to focus on assets Iran uses to sense ships that it could subsequently target. ISW-CTP assessed that the destruction or degradation of these systems would likely impose operational constraints on Iranian forces attempting to disrupt shipping.

That distinction is strategically important.

A missile launcher is dangerous, but a missile launcher without reliable information about where a target is becomes considerably less useful. The same principle applies to mines, fast attack craft, drones, rockets, and other systems. Their effectiveness depends on a broader chain of intelligence, surveillance, targeting, communications, and command-and-control.

Washington therefore appears to be attacking the chain rather than merely intercepting individual attacks.

This is also consistent with the broader pattern of recent American operations. Earlier US strikes reportedly targeted Iranian mine-laying capabilities around Larak Island after Washington assessed that Iranian forces were preparing to deploy mines into the Strait of Hormuz. The latest strikes against radar and related systems represent another stage in the same logic: prevent Iran from converting its geographic position into an effective maritime denial system.

The objective is not necessarily to make Iranian attacks impossible. That would be an extremely ambitious goal.

The more realistic objective is to make them increasingly difficult, expensive, unreliable, and operationally constrained.

That distinction matters because Iran has already demonstrated that it can adapt.

Iran Has Not Lost the Ability to Threaten Shipping

The danger for Washington is that operational constraints should not be confused with operational paralysis.

ISW-CTP's September 1 assessment makes precisely this point. Iranian attacks against shipping on August 30 and 31 demonstrated that Tehran retains some ability to strike vessels using routes through the southern part of the Strait of Hormuz. The fact that Iran managed to hit ships does not necessarily mean that its broader maritime campaign is unconstrained. Rather, it indicates that Iran can still overcome some of the constraints imposed on it.

That is an important distinction for policymakers and markets.

A military campaign can be operationally constrained and still be strategically disruptive.

Iran does not have to attack dozens of tankers every day to create uncertainty. A small number of successful attacks can have an outsized psychological and economic effect if shipping companies conclude that the probability of another attack has become unacceptable.

The maritime insurance market does not operate according to battlefield arithmetic. A handful of successful attacks can change risk calculations across thousands of commercial voyages.

This is why the Strait of Hormuz has become such a powerful Iranian instrument.

The geography does much of the work.

Iran does not need to possess uncontested control of every square kilometer of the waterway. It only needs sufficient capabilities to make its adversaries and commercial actors believe that passage can be contested.

The strategic value of the strait therefore comes not only from what Iran can physically destroy, but from what Iran can make others fear.

The Southern Route Creates a New Military Problem

The emerging use of the southern route through the Strait of Hormuz is particularly significant.

ISW-CTP assessed that Iranian attacks on vessels using this route demonstrate that Tehran retains the capacity to threaten shipping even when vessels attempt to avoid areas where Iranian forces have stronger positioning. At the same time, US forces have been escorting vessels through the southern route, helping restore some shipping activity.

This creates an increasingly direct contest.

Washington is effectively trying to prove that Iran cannot determine who can pass through the strait.

Tehran is trying to prove the opposite.

The United States wants commercial shipping to demonstrate that alternative routes, escorts, surveillance, and military protection can overcome Iranian attempts at maritime denial. Iran wants every successful attack to reinforce the perception that American protection cannot guarantee safe passage.

The resulting competition is partly military and partly psychological.

This is why the September 1 strikes against Iranian radar systems are so important. If Washington can systematically degrade Iran's ability to detect ships, the United States may gradually restore a degree of freedom of navigation without having to destroy every Iranian missile, drone, fast boat, or mine.

But Iran is likely to respond by improvising.

ISW-CTP noted that Iranian forces have used fast attack craft and visual recognition to help identify vessels when more sophisticated sensing capabilities are unavailable. Such methods are significantly less efficient than purpose-built sensors, but they demonstrate Tehran's willingness to adapt.

The result could be a prolonged contest in which Iran becomes less sophisticated but not necessarily harmless.

The Real Battlefield Is the Global Energy System

The Strait of Hormuz matters because its military significance cannot be separated from its economic significance.

The latest escalation immediately affected oil markets. Reuters reported that Brent crude settled above $94 per barrel on September 1 after the renewed US-Iran fighting intensified fears of prolonged disruption to Middle Eastern energy flows.

Yet the most revealing development came on September 2, when US Energy Secretary Chris Wright said that approximately 17 million barrels of crude had passed through the strait on Monday. That figure indicates that significant volumes of oil can still move despite the military confrontation.

This apparent contradiction is central to understanding the conflict.

The Strait of Hormuz does not need to be physically closed for global markets to suffer.

It is enough for the market to believe that its reliability has deteriorated.

The result is a risk premium.

Shipping companies demand greater protection. Insurers increase premiums. Traders anticipate shortages. Governments release strategic reserves. Importers seek alternative suppliers. Producers reassess export routes. And every additional military incident creates another layer of uncertainty.

Iran can therefore obtain strategic effects without achieving complete physical control of the waterway.

That is the core argument behind the concept of “institutionalizing” control over Hormuz. The objective is not necessarily a permanent blockade. It is the creation of a political and economic environment in which Iranian military power becomes an unavoidable factor in determining maritime behavior.

Tehran Is Fighting a War of Adaptation

The United States possesses overwhelming advantages in surveillance, air power, naval power, precision strike capabilities, and logistics.

Iran knows this.

Tehran therefore has little incentive to fight the United States according to American preferences.

Instead, Iran can pursue a strategy based on adaptation, dispersion, ambiguity, and persistence.

The Iranian military does not need to defeat the US Navy in a conventional confrontation. It needs to make American military superiority insufficient to guarantee uncontested commercial navigation at acceptable cost.

That is a much more achievable objective.

The same logic has appeared throughout the wider conflict.

Iran and Iran-aligned forces have repeatedly sought to attack American facilities, regional partners, shipping, and other vulnerable points rather than attempt a conventional confrontation with superior American formations. The regional consequences of this strategy have been particularly visible in Iraq and the Kurdistan Region, where US-linked facilities and infrastructure have increasingly become exposed to the wider war.

My earlier analysis, “US Pushes Iraq to Curb Iran-Backed Militias as Regional Tensions Escalate,” examined how pressure on Baghdad was becoming an increasingly important component of Washington's regional strategy. That pressure has become even more relevant as Iran seeks ways to distribute the costs of the conflict across multiple geographic theaters.

For Iraq, this is an uncomfortable position.

Baghdad cannot control the strategic decisions of Washington or Tehran, yet Iraqi territory remains exposed to the consequences of their confrontation.

The Kurdistan Region is even more vulnerable.

Iraq and Kurdistan Cannot Treat Hormuz as Someone Else's War

It is tempting to regard the Strait of Hormuz as a Gulf problem with limited implications for Iraq or Kurdistan.

That would be a mistake.

The war is increasingly interconnected.

Iranian pressure on Gulf shipping, attacks against American facilities, Iranian-backed armed groups in Iraq, Iranian Kurdish opposition groups based in Iraqi Kurdistan, and American military deployments all form part of a single strategic environment.

The Kurdistan Region has already experienced this reality directly.

In “Erbil Under Fire Again: What the Drone Attack Reveals About the Next Phase of the U.S.–Iran Shadow War,”, I argued that repeated drone attacks against Erbil demonstrate how the Iran-US confrontation is transforming the security environment of Iraqi Kurdistan.

The vulnerability is becoming more serious as American military protection changes.

My analysis, “Kurdistan’s Air Defense Crisis Exposes the Cost of America’s Military Drawdown,”, examined the consequences of declining American air-defense coverage for the Kurdistan Region. The strategic problem is not simply that individual drones may penetrate defenses. It is that the broader architecture that once gave Erbil a degree of protection is changing at precisely the moment regional military risks are increasing.

That creates a difficult paradox.

Washington may be reducing some elements of its military presence in Iraq while simultaneously becoming more deeply involved in the strategic confrontation with Iran.

For Erbil, the implication is obvious: American strategic engagement with Iran does not automatically translate into permanent American protection for Kurdistan.

This was also central to my earlier article “Erbil’s New Air-Defense Reality: What the Latest Drone Attack Reveals About Kurdistan’s Vulnerability,”.

The lesson is increasingly difficult to ignore. Kurdistan's strategic value to Washington does not eliminate its vulnerability to Tehran.

Pezeshkian’s SCO Diplomacy Is Part of the Same War

The military contest around Hormuz is only one side of Iran's strategy.

The other is diplomatic and economic.

Iranian President Masoud Pezeshkian attended the Shanghai Cooperation Organisation summit in Bishkek on August 31 and September 1 alongside leaders including Russian President Vladimir Putin, Indian Prime Minister Narendra Modi, Chinese representatives, and other regional leaders. The SCO itself confirmed that the summit took place in Bishkek on September 1.

ISW-CTP assesses that Pezeshkian may have used meetings with regional leaders to seek military and economic assistance as Iran faces pressure from American and Israeli strikes, sanctions, disrupted trade routes, and restrictions on its energy exports.

The word “may” is important.

There is no reason to assume that every private meeting produced a military commitment. Official readouts are frequently diplomatic and deliberately vague.

But the strategic incentive is clear.

Iran needs economic breathing space and alternative channels of supply.

Russia matters because it remains an important Iranian partner and provides avenues for military and non-military goods. China matters because it is Iran's overwhelmingly important oil customer. The war has disrupted both the physical movement of Iranian energy and the broader commercial networks on which Tehran depends.

This means Pezeshkian's diplomacy is not separate from the battlefield.

It is an extension of it.

If Iran can compensate for American pressure through Russia, China, regional trade networks, and alternative transport corridors, Washington's military campaign becomes less economically decisive.

If Iran cannot do so, the pressure around Hormuz becomes much more consequential.

China and Russia Are Iran’s Strategic Lifelines—but Not Unlimited Ones

Iran's relationship with China is particularly important because the energy dimension of the conflict is ultimately about revenue.

Reuters reported that the US naval blockade has sharply reduced Iranian crude exports, with Iranian loadings falling dramatically from earlier levels.

This gives Washington an important source of leverage.

But economic warfare also creates incentives for Tehran to find workarounds.

That is where China's position becomes complicated.

Beijing has a major interest in Iranian oil, but it also has a major interest in stable energy markets and freedom of navigation. China therefore has reasons to prevent Iran from collapsing economically while simultaneously having reasons to prevent the Strait of Hormuz from becoming permanently unstable.

Russia faces a similar dilemma.

Moscow benefits strategically from American difficulties in the Middle East, but Russia does not necessarily benefit from a total breakdown of global energy markets or from a confrontation that becomes uncontrollable.

Pezeshkian's challenge is therefore not simply to ask whether Russia and China support Iran.

They do, in different ways.

The more difficult question is how far they are willing to convert that political support into material assistance that changes Iran's battlefield position.

That remains uncertain.

The Gulf States Have Their Own Strategy

The Gulf monarchies are watching this contest with a different calculation.

They depend heavily on American security but cannot afford to become direct participants in a war with Iran.

This is precisely the strategic dilemma examined in my September 1 analysis, “The Gulf Is Divided: Who Wants Peace, Who Fears War, and What Comes Next in the US-Iran Conflict.”

Saudi Arabia, the United Arab Emirates, Qatar, Bahrain, Kuwait and other regional actors do not necessarily share identical assessments of how the conflict should end. But they share one fundamental interest: the protection of energy infrastructure and maritime commerce.

The Iranian response on September 1 therefore creates a difficult regional calculation.

If Gulf states become too closely associated with Washington, they risk becoming Iranian targets.

If they distance themselves from Washington, they risk weakening the security architecture on which their economies depend.

That is why Iran's threats against regional US facilities are strategically significant even when the attacks themselves achieve limited military effects.

Iran is attempting to change the political calculations of America's regional partners.

The United States is attempting to convince those same partners that American military power remains capable of protecting them.

The Strait of Hormuz is therefore simultaneously a maritime battlefield and an alliance test.

The Most Dangerous Outcome Is a New Normal

The greatest danger may not be a spectacular Iranian closure of the Strait of Hormuz.

It may be something more gradual.

A new normal in which shipping remains technically possible but increasingly dependent on military escorts, intelligence support, insurance premiums, alternative routes, and political guarantees.

Such an outcome would allow Iran to claim that it has demonstrated control without having to sustain a formal blockade.

Washington would simultaneously claim that it has preserved freedom of navigation.

Both sides could declare partial victory while the global economy absorbs the cost.

That is why the coming weeks matter.

ISW-CTP intends to monitor not simply whether Iran attacks shipping, but the frequency of attacks and the tactical methods used. That is the right metric. A declining attack rate combined with increasingly improvised targeting methods would suggest that American strikes are imposing meaningful operational constraints. Conversely, a sustained or increasing attack rate despite the destruction of Iranian sensors would indicate that Tehran is successfully adapting.

The distinction will be crucial.

What Comes Next?

Three strategic trajectories are now possible.

The first is progressive Iranian degradation. American strikes destroy enough Iranian sensing, communications, missile, mining, and maritime capabilities that Tehran can no longer reliably threaten shipping. In this scenario, the United States gradually restores freedom of navigation and forces Iran toward negotiations.

The second is Iranian adaptation. Tehran compensates for destroyed radar systems through visual detection, drones, dispersed sensors, fast attack craft, alternative launch sites, and asymmetric tactics. Iran does not regain full control of the maritime environment but retains enough capability to impose persistent uncertainty.

The third is strategic escalation. Iran concludes that limited attacks are insufficient to change American calculations and expands its campaign against US and allied assets across Iraq, the Gulf, Jordan and other theaters. Washington responds with increasingly deep strikes against Iranian military and economic infrastructure.

The third scenario is the most dangerous.

It would transform the struggle over Hormuz from a contest over shipping into a broader regional war.

For Iraq and Kurdistan, that would be particularly damaging.

My earlier analysis, “Kurds as a Burnt Card: The Future of the Iran–US Conflict,”, argued that Kurdish actors face a fundamental danger: becoming strategically useful to outside powers without possessing sufficient political protection to withstand the consequences.

That warning now applies beyond the Kurdish question.

Iraq itself risks becoming the geographic space in which competing powers exchange pressure without either side accepting responsibility for the consequences.

The Strait Is No Longer Merely a Chokepoint

The September 1 exchange demonstrates that the Strait of Hormuz has become much more than a narrow maritime passage.

It is now a test of Iranian military resilience, American power projection, Gulf confidence, global energy security, and the credibility of international freedom of navigation.

Iran does not need to permanently close the strait to win something from the confrontation.

The United States does not need to destroy every Iranian maritime capability to claim success.

Both sides are instead competing over the degree of control and uncertainty they can impose.

That makes the conflict unusually difficult to resolve through military force alone.

Washington can destroy radars.

Iran can rebuild them.

Washington can strike mine-launching systems.

Iran can search for alternative methods.

The United States can escort tankers.

Iran can attempt to make those escorts costly.

And every successful Iranian attack can reinforce the perception that the strait remains vulnerable.

This is ultimately a contest over credibility.

If Washington succeeds in maintaining commercial traffic despite Iranian attacks, Tehran's claim to effective control over Hormuz weakens.

If Iran continues to demonstrate an ability to strike vessels despite American military superiority, Washington's ability to guarantee safe navigation becomes more complicated.

The outcome will therefore not be determined solely by the number of missiles fired or targets destroyed.

It will be determined by who can sustain operational pressure longer—and who can convince the international shipping industry that its preferred version of the Strait of Hormuz is the one that will endure.

For Iran, the strategy is increasingly clear: turn geography into leverage.

For the United States, the challenge is equally clear: prevent that leverage from becoming a permanent feature of the regional order.

And for Iraq, Kurdistan and the Gulf states, the uncomfortable reality is that neither objective can be pursued without consequences for the states located around the battlefield.

The Strait of Hormuz may be thousands of kilometers from Erbil and Baghdad, but its security is now directly connected to theirs.

The next phase of the Iran-US war will therefore not simply determine who controls a waterway.

It may determine who gets to define the security architecture of the Middle East after the war.
