The war I wrote up in April was a contest over two things at once. Could Iran survive the strikes, and would the model’s prediction hold; would the population fracture, would the command structure fall in on itself. That war is over, and its verdict is the one the earlier post-mortem called. The fixed air defences were conceded by design, the arsenal held at roughly half, and the state cohered rather than cracked. What is running now, four and a half months in, is a different and colder war, and its defining feature is that the moral axis has come apart from the outcome. Nobody is trying to win hearts any longer. Both sides are spending infrastructure and time to push the other across a threshold. The delta is the name for the race between those thresholds.
Before turning forward it is worth fixing that verdict in a single image. Take every instrument in the Iranian order of battle and place it against two axes, how well it survived the coalition’s suppression campaign and how much leverage it delivered to Iran’s own objectives, and the war sorts itself cleanly. The assets the West scored the campaign on, the fixed air defences and the production base and the manned air force it never had to fight, sit in the conceded quadrant, written off as sunk cost by design. The instruments that did Iran’s actual work, the drone fleet, the Hormuz geometry, the shoot-and-scoot mobile batteries still killing aircraft on day thirty-four, and the dispersed command that outlived the decapitation, sit in the winning one. The diagonal from bottom-left to top-right is the entire story of the first war; the coalition dominated the quadrant Iran had vacated on purpose, and Iran won the quadrant the coalition never modelled. What follows is about what happens once both sides know that.
The word is doing real work, so let me define it before the argument leans on it. Delta here is not a metaphor for change in the loose journalistic sense; it is the margin between two competing clocks, the lead one holds over the other at the moment the war terminates. Everything below is an attempt to say what those clocks are, how fast each is running, and which one strikes first.
The Three Clocks
Three quantities are integrating against each other over time, and the conflict resolves on whichever critical line is crossed first.
The first is R(t), the residual power of the Iranian state structure. Not the missile count alone; the composite. It folds in dispersed strike capacity [still near half the arsenal at the April ceasefire, still being fielded on the current reporting], command coherence [decapitated on the opening night but distributed across a generation of engineers, with the Mojtaba succession still unseen, which is a coherence risk not yet priced into anyone’s model], the nuclear card [the highly enriched uranium survived the campaign, on the order of ten weapons-equivalent if driven to weapons grade, and it remains inside the country and outside IAEA reach], and, most importantly for what comes next, the load-bearing functional substrate that lets Iran operate as a twenty-first-century state and sustain a war economy at all – the grid, water treatment, fuel distribution, the food chain. R decays under strikes. Its floor, call it R_crit, is the level below which Iran can no longer function as a coherent belligerent and must capitulate or fragment.
The second is P(t), the accumulated pressure on the coalition to stop. The Hormuz shock propagating outward, the interceptor magazine draining against near-zero replenishment, allies peeling away, and the domestic-legal constraint tightening at home. This is Iran’s real weapon now, and its defining property is that it rises with a delay.
The third is not a clock but the lag that governs the second, τ_H, the time it takes the Hormuz shock to propagate from the strait to the coalition’s own politics. Call it six months, and treat it as the pivot of the entire problem. The Hormuz weapon does not detonate; it seeps. The gradient is already visible. Asia is rationing, on four-day working weeks and export bans, with fuel queues from Karachi to Bangkok. Europe sits weeks behind on diesel and the winter is coming. The United States is insulated but not immune, with pump prices spiking on the coasts even as the Federal Reserve models a serious hit to output. The supply disruption is, by the energy agencies’ own reckoning, the largest in the history of the oil market. But the political pain that forces an off-ramp lands only when the shock reaches the coalition’s electorates and its major creditors’ patience, and that arrival is lagged by τ_H. Iran’s whole task is to keep R above its floor until P crosses its threshold. The coalition’s whole task is to drive R below the floor before the lagged Hormuz pain matures P past the point where continuing is politically survivable.
That is the delta. In the cleanest statement of it, the war ends at
$$t = \min(t_R, t_P),\quad \delta = t_P - t_R$$
where t_R is the moment R would cross R_crit and t_P the moment P crosses P_crit. A positive delta means the coalition breaks first and Iran survives to a settlement; a negative delta means Iran collapses before the world’s pain forces a stop. The whole war is a fight over the sign of a single number.
But a race only has a finish line if the war is being fought to finish, and whether that is so is the first real question. There are two theories of what this campaign is for. They are not variations on a theme; they read every strike on the map differently, and they disagree about what winning would even mean. The first treats the war as a contest for a result – collapse, capitulation, a regime replaced. The second treats it as a thing with no finish line at all, a mechanism for holding Iran permanently beneath a line it is never again allowed to rise above. Take them in turn, because which one is true decides everything that follows.
The First Reading: A War for a Result
Read the war as a contest for a result and it is exactly the race above; Iran survives if its pressure clock reaches the coalition’s off-ramp before the coalition’s strikes reach Iran’s floor. This is the war Washington’s own planning assumes it is fighting, and the thinking behind the move to civilian infrastructure is a coercion model of great antiquity. Raise the cost of resistance high enough and the adversary’s cost-benefit calculation flips to capitulation. It rests on four assumptions, and all four are miscalibrated against this adversary in a way that mirrors the Lanchester error the April piece diagnosed, only now projected forward.
It assumes, first, a finite reservation price – that some level of pain exists at which Tehran folds. A regime fighting for survival as a civilisational state holds a reservation price on survival that runs to infinity, because for it capitulation and death occupy the same coordinate; you cannot coerce a surrender from an actor for whom surrender is not a lesser outcome than the fight. It assumes, second, that infrastructure targeting degrades will, the old inside-out theory of airpower from Douhet through Warden. The historical record on strategic punishment of a cohesive population is a near-unbroken run of failure at producing morale collapse, from the Blitz to the Rolling Thunder years to the Dahiya doctrine run, as I earlier article put it, at civilisational scale; it produces cohesion, not fracture. It assumes, third, that resource superiority is the same thing as staying power. It is not, because this war is not spent in the currency America is rich in, which is output and platforms, but in the currency it is poor in, which is interceptors, and there the magazine is already half-gone with a rebuild measured in years and every round mortgaged against the Pacific. The magazine derivaitve takes into account the pulling of internal components out of captured Shaheds to build the $35,000 LUCAS and other low cost tactical attempts CENTCOM and others have employed in this war including Israelis using Sparrow family low-cost target missiles for ALBMs originally developed to simulate Scud and Shahab-3 ballistic threats and saving their high-end exotic magazine depth. It assumes, fourth and most consequentially, that time is neutral or friendly. Time is Iran’s ally, because τ_H matures the Hormuz shock, the magazine drains, and allied cohesion decays with every image of a struck water plant.
Set the four together and the shape is clear. Washington is running a coercion-and-cost-imposition model built for a rational unitary actor with a finite price and a neutral clock, against a survival-motivated actor with a near-infinite price and a clock that runs the other way. Same inversion as the air war, new domain.
The Second Reading: A War for a Ceiling
The second reading takes the opposite premise. Suppose the war is not fought for a result at all; suppose the aim is not to cross a threshold but to hold Iran below one, to keep the state alive but hollow, functional enough to avoid the costs of its own collapse yet too degraded ever again to project power or reconstitute as an operational threat. Then the war has no finish line. It has a setpoint. There is a third line on the chart, above the collapse floor and quite deliberately not at it – R_target, the ceiling under which Iran is to be pinned and held.
The band between the two, above R_crit and below R_target, is the objective. Above the ceiling, Iran is a state-level military option again. Below the floor lies collapse, and collapse is a cost the coalition does not want to own, because a fragmented Iran means the enriched uranium dispersing beyond anyone’s account, a refugee flood into Turkey and the Gulf, and a vacuum filled by actors less controllable than the one just broken. The corridor is intact enough to avoid all of that, and degraded enough to project nothing.
This is not a doctrine improvised for Iran. It is the oldest instrument in the Israeli repertoire, which I’ve named many times. MABAM, the Campaign Between Wars, that so-called maintenance doctrine, two decades of assassinated scientists and sabotaged centrifuges holding a capability below a line, indefinitely. Genocide in Gaza, law mowing as Zionists term it, was periodic degradation to the same end. The No-Day-After posture is the confession – you decline to plan for what replaces the regime because you do not want it replaced, only suspended. Epic Fury was that logic escalated from a proxy to a state; and the cohesion result, the finding that fragmentation and regime change were unachievable, did not end the campaign. It collapsed the achievable objective back down into the management band. The maximalists wanted Iran below the floor. Cohesion took that off the table. What remains, what the war now optimises for whether by design or by default, is the corridor.
The critical limit is therefore real, and the division of labour is the one the first piece described – Israel sets the ceiling, America enforces it. The limit is not a number on a card but a composite reconstitution ceiling, an intelligence product expressed across several axes at once: missile production held below a fraction of the pre-war rate, breakout time held above a threshold through the enrichment stockpile and centrifuge count, command depth kept too thin to rebuild expeditionary reach, the Axis inventory kept broken, and beneath all of it the industrial and economic base that funds the rest, which is what the sanctions exist to clamp. That bundle is R_target. It is Israeli-defined because it is Israel’s threat matrix; it is American-enforced because America owns the magazine.
On this reading the binary breaks, and survival stops being the measure of victory. Iran can hold above the collapse floor, can come through in every sense Figure 2 tracks, and still lose the war, clamped beneath R_target with no way back up. A Republic left breathing but hollow, kept alive only because a corpse in that geography would be more dangerous than a cripple, is exactly the end-state the coalition wants; it survives on the coalition’s terms and to the coalition’s purpose. The contest has moved from the floor to the ceiling. Seen from there, the strikes on Iran’s civilian infrastructure take on their real function, pressing the ceiling steadily downward, and the destruction of the production base is the most durable form of it: it leaves Iran alive today and caps how far the country can rise tomorrow. The settlement inherits the same logic, and its fine print is where the war now runs. A toll-and-transit deal that locks sanctions in place, forces intrusive inspection and licenses the occasional maintenance strike would formalise the suppression in treaty, the coalition’s victory delivered over Tehran’s own signature; a deal that lifts the sanctions and lets the base grow back would be Iran’s. The same document, signed in the same room, means opposite things depending on a clause.
However, this doctrine has a flaw as all other propped up doctrines in Zionist repertoire have. Mowing the grass works on a proxy: a finite, externally supplied capability that can be cut back to a setpoint and held there. A civilisational state or a pseudo-state does not obey that physics. It regrows along seams no airstrike can find, through the sovereign knowledge that outlived the decapitation, the enrichment programme spread across a whole generation of engineers, the national identity that every bomb has only hardened, and the grievance that deepens with each cut. And of all the states one might try to hold down this way, Iran is the worst possible choice, because the Iranians did not learn asymmetric warfare from a manual; they wrote the first one. This is the civilisation of the qanat and the underground city, of people who carried their water and their shelter beneath the earth precisely so that no stronger power standing over it could reach them. It is the civilisation of the Parthian shot, of the horse-archers who broke Crassus and his legions at Carrhae by refusing, on principle, to answer Roman weight with weight, bleeding it instead from a distance it could never close. The IRGC’s dispersal, its burial of everything that matters, its harassment of a superior force it will not meet head-on, reaches back two thousand years; it is inheritance, not improvisation, and it lives in precisely the place bombs cannot go. Israel has a line it wants Iran held beneath. No instrument on earth can hold a state of this kind at a fixed line. The band is a spring under compression, and the doctrine that makes it postpones the civilisational contest rather than closing it, feeding the very thing it means to suppress. How long that postponement lasts, and why it ends the way it does rather than the way Israel intends, is the last thing I would settle.
The Scorched-Earth Paradox
Whichever reading is right, the war on the ground is fought with the same machinery, and here is its pivot, the single thing worth holding onto. The escalation to civilian infrastructure is meant to steepen R’s decay. But its effect on R is split, and the two halves point in opposite directions.
On the axis of morale and cohesion, escalation flattens R, and may even raise the floor. Striking water and bridges and grain silos, against a people carrying the living memory of the war with Iraq and the hard distinction between reforming one’s state and accepting its dismemberment by outsiders, hardens the thing it means to shatter. This half of the effect is not merely wasted effort; it is counterproductive, pushing t_R further out.
On the axis of functional systems, escalation can genuinely steepen R – but only through physical de-modernisation, never through morale. Collapse the grid, seize up the fuel distribution, break water treatment and the cold chain, and you degrade the state’s operational substrate and its capacity to run a war economy regardless of how cohesive the population feels. The recent admissions out of the Energy Ministry, the grid attacks and the villages left without drinking water, are the leading edge of exactly this.
The consequence is uncomfortable and it is what most comentators, journalistics, and strategic analysts would miss. The cold, rational targeting logic is not morale-targeting, which is inert, but critical-systems targeting; and the delta on the R side therefore reduces, with some precision, to a question of Iranian infrastructure resilience. Whether Iran can island critical loads, hold black-start capability, run distributed and redundant generation, harden its substations and water and fuel nodes, and keep the functional substrate above the collapse line under sustained kinetic pressure. If Iran loses this war, the collapse mechanism will not be the population turning. It will be just the grid failing to re-synchronise. The side whose decision makers listen to the experts who understand power-system resilience understands where the war is actually decided, and it is not where the cameras are pointed.
Meanwhile escalation moves P in one direction only, toward the off-ramp. More strikes burn more magazine; more civilian harm accelerates allied defection and the pressure of the War Powers machinery at home; and the regional tit-for-tat, Iran’s threat to bring down infrastructure across the Gulf, adds terms to the pressure integral and keeps insurance and oil propagating outward. So the net vector of escalation is this. P accelerates hard toward its threshold, while R is flattened on morale and steepened only on the narrow systems axis. Escalation favours Iran on the delta, unless the coalition can find and collapse the load-bearing systems faster than P matures. THIS is the whole war.
Four Roads From Here
The sustained air campaign, the status quo. America wins tactically every day and loses the delta. Airpower’s marginal return against a dispersed, cohesive, nuclear-backstopped system is low; R settles above its floor while P climbs toward the τ_H knee. On a six-to-twelve-month horizon this resolves in Iran’s favour by P-crossing, and every additional strike buys a headline and spends a clock.
Boots on the ground, meaning a seizure of Kharg or the enriched-uranium stockpile. This option exists precisely because airpower has hit its ceiling; the material is underground, the launchers dispersed, the population coherent, and the case being made for it in Washington is explicit that possession of Iranian soil is a bargaining asset for the negotiation that follows. On the delta math it is the worst trade available. It pulls t_R forward only at the margin and only on narrow objectives, while exposing ground forces to the very cost-asymmetric attrition Iran spent thirty years optimising for, and it pulls t_P forward violently, because casualties detonate a domestic constraint that a knife-edge War Powers vote cannot survive with body bags, allies who will condemn from a distance will not join a land war, and occupation of a cohesive population raises the collapse floor and lengthens the insurgent tail. Seizing Kharg in particular is leverage that may foreclose the very settlement it is meant to enable, because it strips Iran of its last economic lifeline and hardens the nothing-left-to-lose calculus toward total closure of the strait, and its value depends on a negotiation that the reimposition of sanctions has just undercut. It is the reflex of a force structure that, when firepower does not produce the political result, applies more force, because it knows nothing else by design.
The one-year war of attrition. Time is structurally Iranian, gated only on R holding above the floor. At twelve months τ_H is fully matured and compounding into recession, fertiliser and food shocks, and demand destruction; the magazine sits below its Pacific red-lines; allied defection is near-total; and domestic fatigue peaks into an election cycle. If R holds, the long war resolves by P-crossing, which is exactly the outcome Iran’s doctrine was built to produce – trade space and infrastructure for time. The only coalition path to victory in a long war is the systems-collapse of R faster than P matures, and on the current reads that is a race decided by weeks, which is to say it is decided by Iranian infrastructure hardening and by nothing else.
The Hormuz-toll settlement, the equilibrium exit. Both sides can sell this, and its embryo already exists in the June memorandum and the toll Iran is already charging on selective transit. The trade is legible. Iran converts the chokehold into a regulated toll-and-transit regime in exchange for sanctions relief, the release of frozen assets, security guarantees, and preserved nuclear ambiguity, with the uranium left in place and unresolved, which is itself the deterrent residue that makes the settlement hold. This is the most probable rational terminus, conditional on three things: that R stays above the floor so Iran bargains from survival and not from collapse; that the humanitarian-systems floor is not breached first; and that domestic politics in Washington reach the point where the exit is wanted rather than merely gestured at. The catch is that τ_H delays the moment when both sides’ pain is undeniable enough to sell the deal at home, and the sanctions reimposition has pushed Iran toward more throttling of the strait, not less. The settlement is gated on the same clock as everything else, and the delta decides whether the war reaches the toll-booth or the rubble first. And as the corridor framing implies, reaching the toll-booth is not by itself an Iranian victory; this exit is a win for Tehran only if its terms release the ceiling, and a settlement that locks the corridor in is the coalition’s win by other means.
Decomposing the Pressure
The pressure clock is not one thing. It is the sum of three integrals with three different time constants, and pulling them apart is what tells you which lever, if any, moves the settlement date.
$$P(t) = P_{H}(t) + P_{M}(t) + P_{D}(t)$$
The first term, P_H, is the Hormuz economic-coercion integral. Its shape is a lagged ramp, near-flat for the first months and then steepening as the shock propagates west and compounds; it carries the largest terminal magnitude of the three; and its tap is held by Tehran. The second, P_M, is the magazine-depletion integral, a steady near-linear accumulation from the opening day whose slope is set by the coalition’s own strike tempo, with a fixed external drain sitting under it in the form of the Pacific opportunity cost. The third, P_D, is the coalition-cohesion integral, a punctuated step function that jumps at discrete events – a European condemnation, a burden-sharing quarrel inside NATO, a joint ceasefire demand from Beijing and Islamabad, a privileged resolution on the Senate floor – and climbs fastest when the images of civilian harm are worst.
The payoff falls straight out of the decomposition and it is worth stating plainly. Of the three terms, the two the coalition can influence, the magazine and the defection integrals, it can slow only by de-escalating – throttling strike tempo, reducing civilian harm – and de-escalation also halts the degradation of R, so it brings the coalition no closer to a win; it merely extends the stalemate at lower cost. The third and largest term, Hormuz, the coalition cannot touch at all without reopening the strait, which is the settlement itself. There is no available lever that lowers P while continuing to drive R downward. Escalation raises R-degradation but raises all three pressure terms faster; de-escalation slows the pressure but freezes the coalition’s own progress. The force is caught between a road that feeds Iran’s clock and a road that stops its own.
Which means the clock that ends the war is the Hormuz clock. The settlement date is set, to a first approximation, by τ_H and its compounding, because that is the dominant term and the one Washington does not hold. The other two integrals mostly determine how expensive it is to reach the settlement, not when the settlement arrives. America’s choices set the price. They do not set the date.
The Ground Truth for the IRGC
Strip it to the operational imperative and it is not complicated, which is the point. Iran does not need to win. It needs to not-lose for long enough that P crosses. Everything the IRGC does now is either keeping R above the floor or accelerating P, and the regional infrastructure tit-for-tat is the second, not the first. Striking Gulf desalination, power and gas is not moral symmetry and it is not revenge; it is Iran manufacturing additional pressure by forcing the coalition’s Gulf hosts and their economies into the cost equation, which accelerates allied defection and the propagation of insurance and oil shocks. It is a term added to the integral. Read that way, the threat to bring infrastructure down across the region is not rhetoric. It is doctrine, and it is aimed at P.
The genuine risk to Iran is the one the systems view catches and the morale-obsessed commentary misses. If the coalition’s targeting migrates from symbolic civilian sites to the load-bearing nodes, and Iranian hardening, redundancy and islanding prove inadequate, R can crack from the bottom while cohesion remains perfectly intact. A state that cannot pump water or move fuel has lost the war even with a population that would fight to the last house. That, and not the protests and not the decapitation of the leadership cohort, is the axis on which Iranian survival is now actually contested.
The War as a Stumble
There is a way to see the whole thing at a glance, and it needs no mathematics. Think of what happens when you trip. A shove sends you pitching forward, and for a moment you are carried on momentum, tipping further with each stride. Whether you stay up has nothing to do with how hard the shove felt; it is a question of whether you can throw enough weight back to arrest the fall before you pass the point where nobody recovers. Beyond that point you are going down no matter what you do. Short of it, you stagger and stay standing. The war is that stumble. The campaign is the shove; Iran’s recovery is everything it can push back with, the toll on the strait and the emptying magazine and the allies walking away; and collapse is the point past which no recovery is possible.
Two things follow, and both are visible in any stumble. The first is that a body which digs in and braces takes the shove more slowly, and so has more time to catch itself; hammering a population that hardens under the blows is not merely wasted, it hands Iran the very time it needs. The second is that sending in ground troops is getting up and stepping straight back onto the same ice. You go down again, and again, and again. That is the Afghanistan trap, and it is the one move that turns a stumble into a fall.
The Decade the Clamp Buys
No single settlement resolves this, because the war does not run in one continuous line; it comes in pulses, war and truce and war again. The first memorandum has already collapsed. A second waits on the same clock as everything else, arriving once the Hormuz pain matures past what Washington can absorb, which the propagation lag puts somewhere in the next six to nine months, after European diesel has bitten, the second-order shocks in food and fertiliser have landed, and the interceptor magazine has fallen through its Pacific red-line. That second memorandum will be a thinner document than the first, a renegotiated toll-and-transit arrangement in all likelihood, leaving the nuclear file untouched where it sits, unresolved and quietly useful to Tehran. From there the pattern repeats. Strike tempo climbs, the Hormuz pain matures, a settlement freezes the board, and both sides work the freeze to opposite ends, the coalition lowering the ceiling by another notch and Iran rebuilding beneath it, until the terms fray and the tempo climbs again. What each memorandum buys is a pause between mowings, and the decade is a run of these, every one of them signed from a coalition hand a little weaker than the round before.
That slow weakening is the hinge, because the clamp comes with an expiry date that Israel cannot set. Ten years is the outside estimate, and the limit is structural. A suppression on this scale can only be run inside a unipolar order, where one hegemon underwrites the enforcement without ceiling and shuts off every route back up that it does not itself hold open. That order has already passed, the Iran is not an Iran or Afghanistan of 19th century and Americans/Israelis are no British Empire. With multipolarity setting in and the regional balance sliding back toward parity, the scaffolding under the whole strategy rots from below: sanctions bleed through Chinese and Russian channels, patrons the coalition cannot reach lift the reconstitution ceiling that airpower had pinned, and an enforcement bill an unchallenged hegemon could carry turns ruinous for a contested one. A colonial polity of nine million, built on an apartheid structure, has no way to keep a cohered civilisational state of ninety million pressed down once the subsidy of American primacy thins beneath it, and that subsidy is thinning now.
The decade, then, closes on something other than the outcome the clamp was bought to produce. MABAM rested on a permanent asymmetry, a target that could never climb back and a patron forever willing to pay to keep it down, and the multipolar horizon voids both terms. Year ten yields an Iran climbing back into a region that no longer answers to the coalition’s writ, across the table from a Zionist power structure that has burned its enforcement capital holding down a spring it can no longer afford to compress. The suppression buys no resolution; it warehouses the problem and delivers it, intact and heavier, to an Israel weaker against its neighbourhood than the one that first turned the key. The clamp is a tactical win laid over a strategic loss, and the bill for the second comes due about a decade after the first is banked.
What It Comes Down To
Strip away the models and the maps and the war reduces to a few plain sentences.
By the kill-count, America and Israel have won; Iran has lost most of what can be photographed. But the count is measuring the wrong thing. This war is not decided by what gets destroyed. It is decided by a race between two kinds of exhaustion – how fast Iran’s grip on the world’s oil and the drain on America’s stock of interceptors force Washington to stop, against how fast the bombing can hollow out Iran’s ability to keep functioning as a country.
Three things decide that race, and none of them is the rubble. You cannot bomb a people like Iran’s into turning on their own state; a century of air campaigns says it hardens them instead. The only thing bombing can really do is wreck the plumbing of a modern country, the power and the water and the fuel, so the war turns on whether Iran can keep the lights on, not on whether its people lose heart. Time is on Iran’s side, because the pain of a throttled Strait of Hormuz reaches the world’s economies on a delay of months, and every one of those months drains America’s magazine faster than its factories can refill it. And the real aim was probably never to destroy Iran at all; it was to leave it alive but crippled, held down for good so that it can never again threaten the order Israel wants in the region.
That last aim is the one that does not work. You may hold a militia down by cutting it back every few years. You cannot mow a forest that has decided to be a forest. You can bomb a nation into the dirt for a season; you cannot keep it there, because the things that make it dangerous – its knowledge, its sovereignty, its sense of itself – are exactly the things bombs cannot reach, and they grow back stronger and angrier with every round.
So the likeliest ending is neither an Iranian collapse nor an American victory but a deal: Iran charging a toll on the world’s oil in exchange for being left standing. Who actually won will be buried in the fine print, in whether that deal keeps Iran boxed in or lets it rebuild. And whichever it is, it will not be an ending. A nation held down by force is a spring under compression. Far from settling it, this war is just scheduling the next one.
If you want a single thing to watch, ignore the strike tallies out of CENTCOM and watch the price of diesel and Kerosene in Europe and USA. When that pain lands in full, the clock that ends this war will have run down, and the one that starts the next will already be turning.
