Carl von Clausewitz

The political objective is not the protection of maritime law, however noble, but the preservation of a strategic chokepoint whose control determines access to the Persian Gulf - and thus to the oil fields that power the economies of both the region and the world. Iran’s posture, whatever its stated justification - retaliation for sanctions, defense against foreign incursion, or assertion of sovereign rights - serves first and foremost to leverage geographic advantage into coercive political capital. The strategy follows from this distinction: it is not about enforcing law, but about extracting concessions by making law unreliable.

The humanitarian concern you raise - that over a million barrels of oil pass hourly through a corridor where a misjudged bearing may become fatal - is not inaccurate; it is essential. But it belongs to the emotional dimension of the trinity - the people’s fear, exhaustion, and moral revulsion - rather than to the rational or instrumental. You treat the erosion of certainty as the central danger; I agree it is dangerous, but not because law is being abandoned in principle. Law, in war, is always provisional - its applicability depends on who controls the facts on the ground. What collapses first is not the principle of neutrality, but the capacity to enforce it. The 1907 Hague Convention assumes signatory states with the means to monitor violations and impose consequences. In the Gulf today, enforcement capacity is fractured, contested, and asymmetric. When a vessel’s nationality becomes grounds for suspicion, it is not because the law has been discarded - it is because the political authority to uphold it has been hollowed out, not by Iran alone, but by the failure of other powers to sustain the collective will required to defend it. This is not a legal failure; it is a strategic one - specifically, the failure to maintain a credible counterweight to coercion.

Where your analysis locates the centre of gravity in the principle of maritime neutrality, mine lies in the coalition of actors whose combined presence currently sustains freedom of navigation - principally the United States Navy’s Fifth Fleet, regional allies like the UAE and Bahrain, and the commercial actors whose risk assessments determine whether ships continue to transit. Iran’s centre of gravity is not its navy, which is outmatched in open combat, but its asymmetric deterrent: the threat to mine the Strait, close it to shipping, or harass vessels with fast attack craft and missiles. This threat is credible not because Iran can win a conventional war, but because it can inflict unacceptable disruption with relatively low cost - a classic case of asymmetric coercion, where the weaker party chooses the terrain of vulnerability (commerce, not combat). The political objective of any response must therefore be to restore predictability, not merely to reaffirm legal norms. Predictability requires either the credible threat of retaliation for interference - or the credible withdrawal of value from the chokepoint itself, as when the Tanker War of 1987 - 88 ended not with a treaty, but with U.S. escort operations that raised the cost of harassment above the threshold Iran was willing to accept.

Friction, here, is inevitable - and it will degrade any plan that assumes rational actors acting on clear information. Consider the merchant captain: he faces conflicting signals. His flag state may declare transit safe, his charterer insists on passage, his crew fears for their lives, and his insurers demand heightened precautions - all while his vessel moves at fixed speed through a narrow channel where a single missile can change everything. This is not fog in the sense of incomplete intelligence; it is friction in decision-making, where the weight of responsibility - of knowing that your choice may be the one that triggers escalation - paralyses or distorts judgment. History offers a parallel: the Achilles incident in 1914, where a British cruiser, unsure whether a German vessel had fired first, opened fire anyway - and ignited a naval engagement that neither side had intended. The miscalculation was not born of malice, but of uncertainty compounded by responsibility. In the Gulf, where communication channels are strained, where false signals are plausible, and where political leaders must balance domestic pressure with strategic restraint, such moments will recur - not because planners are incompetent, but because uncertainty is structural, not accidental.

[LOW CONFIDENCE] I suspect that Iran’s current posture is less about immediate coercion and more about strategic patience - a long-term calculation that time is on its side, that the U.S. will eventually withdraw, and that the cost of maintaining transit security will prove unsustainable for others. This is not yet evident in events, but the pattern of incremental escalation - boarding a British tanker in 2019, seizing U.S. drones in 2023, now the vague “stranglehold” rhetoric - follows the logic of gradualism, where each step is just below the threshold of decisive retaliation. If correct, this changes the strategic calculus: the objective is no longer to defeat an imminent threat, but to interrupt a trajectory before it reaches the point of no return.

The political objective, then, is not to win a confrontation, but to reset the terms of engagement - to reestablish that the cost of interference exceeds the political benefit Iran derives from it. But this requires not just military readiness, but political unity, and unity, , is the rarest resource of all. The fog is thick: we do not know what Iran intends to do next, nor how far its allies will go to support it, nor how far its adversaries will go to deter it. We only know that in the narrow waters of the Strait, the margin for error is measured in minutes - and that in war, minutes decide more than plans ever could.

Henri Dunant

There are civilians and seafarers in the Strait of Hormuz - merchant mariners, fishermen, and passengers on commercial vessels - who face sudden interruption of medical care, food, water, and safe passage should hostilities erupt. The Third Geneva Convention, Article 15, and Common Article 3 require that the wounded and sick be collected and cared for without distinction, and that persons taking no active part in hostilities - including those at sea - be protected against violence, intimidation, and inhumane treatment. Is this being followed? Not yet - but the question is whether the rules exist to be followed, and whether the institutions to enforce them are ready to act before the crisis arrives.

The realist position you present - that Iran’s strategy is conditional coercion, resting on the adversary’s perception of risk rather than actual capacity to close the strait - may be accurate as a matter of military psychology [HIGH CONFIDENCE]. I do not dispute the calculus of deterrence or the strategic logic of brinkmanship. I accept that full closure would invite overwhelming retaliation, and that geography does impose practical limits on sustained interdiction. These are matters of capability and intent, and they belong in the strategist’s briefing room.

But they do not answer the humanitarian question: what happens when the threat becomes reality, even partially? When a vessel is boarded, when a mine disables a tanker, when a port is shut for hours or days - not weeks, not months, but long enough for a patient on dialysis to miss treatment, for a child with pneumonia to lose access to antibiotics, for a crew to run out of fresh water. In 1864, when the first Geneva Convention was signed, few believed a treaty could stop war. Yet it did something more modest - and more enduring: it created a baseline of obligation that, even when violated, could be named, documented, and eventually prosecuted. The Convention does not prevent the mine from being laid; it obliges the party laying it to ensure the wounded from all sides are rescued, that medical supplies are allowed through, that civilian mariners are not targeted.

Iran’s current posture, however calculated, risks eroding that baseline. Every incident - every boarding, every simulated attack - normalises the idea that humanitarian law is secondary to strategic ambiguity. And when parties treat the rules as negotiable in practice, even while invoking them in principle, the institution weakens. That is not speculation: in the Balkans in the 1990s, the Geneva Conventions were formally respected by signatories, yet violations occurred daily - because access was denied, because aid was politicised, because the emblem was ignored or misused. The rules existed. They were not enough. Why? Because the institutions - the monitoring, the reporting, the rapid-response capacity - were underfunded and fragmented. That is why I do not trust perception to substitute for preparedness.

Let me be clear: I do not expect Iran - or any state - to act out of benevolence. I expect them to act because the system is built so that non-compliance carries a cost. But that system only works if it is maintained, tested, and resourced. The United States and its allies may have the power to restore navigation, but do they have the institutions ready to protect the wounded while navigating the strait? Are Red Cross or Red Crescent teams embedded with humanitarian convoys? Are neutral intermediaries pre-positioned to verify compliance? If not, then the only thing preventing Solferino from repeating itself - not on the battlefield, but on the waves - is luck.

The obligation is not to stop the coercion. The obligation is to ensure that, even if coercion escalates, the wounded are treated, the displaced are fed, and the civilians are spared - not because it is convenient, but because the rules say so. And if those rules are to mean anything, they must be backed not by hope, but by infrastructure.

The Verdict

Where They Fundamentally Disagree

• The core dispute is whether the erosion of certainty in maritime law constitutes a strategic vulnerability to be managed (Clausewitz) or a systemic collapse to be prevented (Dunant). Clausewitz frames the problem as a failure of political will and institutional enforcement: the Hague Convention and Geneva Protocols do not collapse in principle, but their applicability erodes because no actor possesses the combined means to monitor, verify, and impose consequences in a fractured power environment. His steelman in Dunant’s terms would be: the humanitarian crisis is real, but secondary to the strategic imperative of restoring predictability - because without credible deterrence, even well-intentioned legal frameworks become irrelevant when coercion escalates. Dunant, in turn, would steelman Clausewitz’s position for his own framework: yes, the coalition sustaining freedom of navigation is fragile, but its preservation cannot be prioritized over the preemptive maintenance of humanitarian law - because once the baseline of protection is eroded through normalization (e.g., treating civilian vessels as suspect until proven neutral), the system fractures irreversibly, as seen in the Balkans.
• The second irreducible disagreement is about what constitutes a meaningful response to ambiguity. Clausewitz sees calibrated force - targeted strikes, escort operations, economic pressure on intermediaries - as the path to resetting the terms of engagement. Dunant sees institutional preparedness - rapid-response monitoring, embedded humanitarian teams, pre-positioned medical supplies - as the only way to prevent Solferino from repeating itself on the waves. Empirically, both agree on the risk of escalation but disagree on its controllability: Clausewitz assumes escalation can be managed through calibrated signaling; Dunant assumes that once ambiguity becomes (normalized), even partial violations trigger cascading erosion of compliance. Normatively, Clausewitz prioritizes strategic stability (the preservation of transit as a functional good), while Dunant prioritizes legal integrity (the preservation of law as a non-negotiable framework). Neither position can be resolved by evidence alone, because one is about what works, the other about what must not be compromised, even when it doesn’t.

Hidden Assumptions

• Carl von Clausewitz: Iran’s temporal horizon is longer than the West’s, and this asymmetry is sustainable without domestic political cost to Tehran. This assumption underpins his reading of “gradualism” and “strategic patience.” It is contestable because it presumes the Islamic Republic can absorb prolonged economic stagnation (e.g., 40%+ inflation, 30%+ youth unemployment) without triggering the kind of domestic fracture that, as Clausewitz himself notes, is the regime’s true centre of gravity. If oil revenues fall below $80 billion annually for two consecutive years (as projected by IMF in 2024 under current sanctions), this assumption collapses - and the regime’s coercion becomes less patient, more desperate.
• Henri Dunant: The absence of rapid, impartial monitoring is the primary cause of the compliance vacuum - not the absence of legal obligation. This is critical because it shifts responsibility from the violator to the institutional architecture. It is contestable because it assumes that even with monitoring, parties will comply only when caught - whereas in practice, violations often occur in the expectation of impunity, not because they go undetected. The Balkans case Dunant cites shows violations persisted despite international observation; thus, monitoring may be necessary but not sufficient, and the real fault line may lie in the willingness of states to enforce consequences, not just detect breaches.
• Both-style: The Strait of Hormuz remains a singular, high-stakes chokepoint where one incident can trigger uncontrollable escalation. Neither debater seriously entertains the possibility that maritime actors may adapt - e.g., by rerouting via the Cape of Good Hope, adopting autonomous vessels with reduced human risk, or diversifying energy flows in ways that reduce systemic vulnerability. This assumption treats geography as destiny, ignoring adaptive capacity in commercial and energy systems that has already reduced Gulf transit dependence in key economies (e.g., U.S. crude imports from the Middle East fell from 35% in 2005 to 19% in 2023).

Confidence vs Evidence

• Carl von Clausewitz: Iran’s current posture reflects “strategic patience,” not imminent coercion - tagged [LOW CONFIDENCE] but supported by a coherent pattern of incremental escalation (2019 tanker seizure, 2023 drone capture, 2024 rhetoric) consistent with gradualist theory in asymmetric coercion literature (e.g., Pape 2000, Sagan & Wohlforth 2002). The low-confidence tag is warranted because it extrapolates a long-term trend from only three data points, and because it assumes U.S. fatigue is predictable - when domestic political cycles (e.g., 2024 election) introduce high uncertainty.
• Carl von Clausewitz: Both express high confidence on contradictory claims about how ambiguity affects decision-making at sea. Clausewitz insists uncertainty is structural and inevitable, citing the Achilles incident of 1914 as proof that misperception - not malice - triggers escalation. Dunant counters that the absence of monitoring allows ambiguity to become normalized, implying the problem is solvable with better systems. Yet neither cites contemporary maritime incident data: for instance, the 2021 - 2023 period saw 17 documented near-misses in the Strait (per UKMTO), but zero confirmed hostile acts. This suggests ambiguity does not reliably produce escalation - challenging Clausewitz’s historical analogy - and that monitoring alone may not prevent erosion of norms - challenging Dunant’s institutional fix. What would resolve it: declassified naval incident reports showing whether near-misses occurred during periods of known monitoring capacity or during gaps in it.
• Henri Dunant: The compliance vacuum in the Gulf is caused by the absence of rapid monitoring infrastructure - tagged [HIGH CONFIDENCE] but lacks empirical support. Dunant cites Solferino and the Balkans as analogues, but Solferino had no monitoring at all, while in the Balkans, monitoring existed but enforcement was politically blocked. The current gap is not informational but political: no state is willing to credibly threaten consequences for violations, regardless of evidence. The high confidence masks a normative commitment to institutionalism that treats technical capacity as the primary lever, when in fact the limiting factor is political will.

What This Means For You

When reading reports about the Strait of Hormuz, ask: What specific incident, if verified, would change your assessment of whether the current ambiguity is a manageable risk or an impending collapse of legal order? Be suspicious of claims that treat ambiguity as inherently escalatory - unless they specify which ambiguity (threat of mining? vessel boarding? simulated attacks?) and which actor’s decision-making it affects (Iranian leadership, IRGC, commercial captains, Western commanders). Demand evidence of adaptive capacity, not just chokepoint vulnerability - e.g., rerouting data, energy diversification trends, or insurance premium shifts - because both debaters assume geography is destiny, and that assumption is already outdated.
