Alright, so Daniel sent us this one, and it's a big one. He's asking us to examine Operation Epic Fury week by week over its first six weeks — from February twenty-eighth through the ceasefire on April eighth. How did military doctrine evolve on both sides as the campaign unfolded? Did the campaign experience diminishing returns or gathering momentum? And extrapolating from where things stand now, what's the most obvious continuation for the coalition and for Iran? Six weeks of the most intense combined US-Israeli military operation since World War II. There's a lot to work through here.
Herman Poppleberry, and yeah, this is exactly the kind of analysis I've been wanting to do since the ceasefire was announced. Because there's a surface-level narrative — the US and Israel destroyed Iran's military, Iran eventually agreed to stop shooting — and then there's what actually happened doctrinally. Those are two very different stories.
And the doctrinal story is way more interesting. So let's go week by week. Week one. February twenty-eighth. The opening salvo.
So the opening was a textbook Phase One suppression-of-enemy-air-defenses package, but at a scale that was genuinely unprecedented in the modern era. Before a single bomb dropped, US Cyber Command and Space Command initiated what CENTCOM called "non-kinetic effects" to disable Iran's communications. Then more than a hundred aircraft launched from land and sea in a synchronized strike package. B-52H Stratofortresses, B-2 Spirits, B-1B Lancers, Tomahawks from USS Frank E. Petersen Jr. And then something that got less coverage than it deserved — HIMARS firing PrSM ballistic missiles from Bahrain. That was the first operational combat use of the Precision Strike Missile. A significant doctrinal milestone buried in the first day's headlines.
And then Khamenei was killed in the opening hours.
In the opening hours. His office in Tehran, struck alongside dozens of senior political and military leaders. That is the single most consequential event of the entire campaign, and it happened before most people had finished reading the first news alerts. The decapitation was real, it was immediate, and it fundamentally altered the war's trajectory before Iran had fired a meaningful response.
And yet Iran still fired. Week one Iran was not sitting quietly.
Not even close. Iran launched two hundred and two ballistic missiles and two hundred and twenty-one drones at Qatar and the UAE alone in the opening days. They targeted US bases across the Gulf, struck commercial shipping in the Strait of Hormuz, and — this detail I keep coming back to — they successfully hit an AN/TPY-2 forward-based X-band radar at Muwaffaq Salti Air Base in Jordan. That is a Tier One missile defense asset. The War Zone called it "a wake-up call." Iran also hit what sources described as the CIA station in Saudi Arabia — a direct hit, rendered inoperable. Week one Iran was executing a mass saturation doctrine: overwhelm defenses through sheer volume.
So the doctrine mismatch in week one is really interesting. The coalition came in with precision and sequencing. Iran came in with mass and volume.
And by the end of week one, CENTCOM Admiral Brad Cooper was reporting that Iranian ballistic missile attacks were down ninety percent, drone attacks down eighty-three percent, thirty Iranian warships destroyed, sixty percent or more of Iran's roughly four hundred and twenty missile launchers neutralized. The numbers were staggering. Iran's national internet was shut down — what would become the longest national internet blackout on record, eventually surpassing Sudan's thirty-seven-day shutdown in twenty-nineteen. By any conventional military metric, week one was a coalition rout.
And the US took casualties too. Six killed on March first in a drone strike on Port Shuaiba in Kuwait. Plus three F-15s shot down by friendly fire from Kuwaiti air defenses, which is — I mean, that's a brutal way to lose aircraft.
The friendly fire incident is genuinely haunting. Three jets, lost not to Iranian fire but to a coordination failure with a coalition partner. And then March fourth — the IRIS Dena, an Iranian frigate, sunk by a Los Angeles-class submarine off Sri Lanka. The first US submarine torpedo kill since World War II. One hundred and four crew. That's a data point that deserves more weight than it got in the coverage.
Okay, so week two. CENTCOM announces Phase Two on March fifth. And the framing Admiral Cooper used was striking.
It was remarkably candid. He said, and I'm quoting directly: "We're not just hitting what they have, we're destroying their ability to rebuild. As we transition to the next phase of this operation, we will systematically dismantle Iran's missile production capability for the future." That is a doctrine shift announced in public. The target set moves from military hardware to industrial capacity. Underground missile cities, production facilities, the defense-industrial base. The theory shifts from "reduce the threat now" to "eliminate the threat permanently."
Meanwhile Iran shifts too. Week two Iran is less volume, more precision.
Iran's week two targeting was notably more selective. They struck Mehrabad International Airport in Tehran — wait, that's the coalition. Iran struck fuel storage in Bahrain, targeted the Saudi Shaybah oil field with sixteen drones, and hit Dubai International Airport's runway, suspending all flights. They also struck the twenty-three Marina tower in Dubai. Sixteen drones were intercepted over Shaybah, but the intent was unmistakable — Iran was moving from "overwhelm air defenses everywhere" to "hit things that hurt economically and psychologically."
And week two is when the interceptor crisis starts becoming visible.
This is the hidden vulnerability of the entire campaign that the headline coverage almost entirely missed. By week two, EU states were warning at a closed-door Brussels meeting of a global interceptor shortage. South Korea rushed approximately thirty ballistic missile interceptors to the UAE via C-17. Iran was firing a hundred and forty-plus weapons at the UAE in a single overnight period. The coalition was winning the air war over Iran while simultaneously watching its ability to defend Gulf Arab states slowly degrade. Iran's attrition strategy — keep firing, force them to burn interceptors — was working at the margins even as Iran's own offensive capacity was being dismantled.
Also March eighth — the Assembly of Experts selects Mojtaba Khamenei as the new Supreme Leader. And the choice matters.
It matters enormously. Mojtaba is a hardliner backed by the IRGC, in which he himself once served. The selection signaled that Iran's response to having its supreme leader killed was not to moderate — it was to double down. The IRGC picked its man, and its man was not a pragmatist.
By the way — today's script is powered by Claude Sonnet four-point-six, doing the heavy lifting on this one. Alright, week three. March fourteenth through twentieth. The energy war begins.
This is where the campaign's third doctrinal phase becomes legible. On March eighteenth, Israel strikes the South Pars gas field in the Persian Gulf — the field Iran shares with Qatar, one of the largest natural gas fields on Earth. That is a deliberate escalation to economic warfare targeting energy infrastructure. And Iran responds in kind by warning it will target energy infrastructure across the Gulf. Then March twentieth — Iran fires missiles at Diego Garcia. The US-UK base in the Indian Ocean, approximately two thousand five hundred miles from Iranian territory.
Which demonstrated a range capability Iran had not previously admitted to publicly.
The US and Israel both said so explicitly. Iran had been concealing the true range of some of its missile systems, and Diego Garcia was the reveal. That's a significant intelligence failure on the coalition's part — or a deliberate Iranian concealment that worked. And it changes the threat calculus for every US asset in the region, because if Diego Garcia is in range, so is a lot else.
And the Strait of Hormuz closure as a weapon really crystallizes in week three.
Iran started charging fees for passage. That's not just a military action — that's an assertion of sovereign control over an international waterway through which twenty percent of the world's oil transits. The economic pressure that generates is not on Iran. It's on everyone else. Energy prices surge globally. Gulf Arab states — the coalition's partners — start feeling it. Iran found its asymmetric lever, and it was not a missile.
Okay, week four. March twenty-first through twenty-seventh. Trump issues a forty-eight-hour ultimatum to open the Strait.
And then extends the deadline. Which — if you're Iran, that tells you something about the credibility of the ultimatum. The coalition strikes three major Iranian steelworks on March twenty-fourth. Steel production. That's not military infrastructure. That's the economic base. And on the same day, Iranian drones and missiles hit Prince Sultan Air Base in Saudi Arabia, damaging an E-3 Sentry AWACS aircraft and wounding service members. Iran was targeting ISR assets — intelligence, surveillance, and reconnaissance — methodically. Hit the radar in Jordan in week one, hit the AWACS in week four. They were trying to degrade the coalition's situational awareness.
And then the Houthis enter. March twenty-eighth, their first ballistic missile toward Israel.
The Houthis had been largely absent from this conflict until week four, which is interesting given how active they'd been in the Red Sea in the preceding years. Their activation in week four opened a new front and signaled that Iran still had proxy leverage it hadn't fully deployed. Simultaneously, USS Tripoli arrives with three thousand five hundred sailors and Marines, and elements of the Eighty-Second Airborne are heading to the region. There are reports of Trump privately discussing US ground troops inside Iran. The campaign is escalating in every dimension simultaneously.
Week five. March twenty-eighth through April third. This is where the "maximum pressure" framing starts to feel strained.
The gap between the rhetoric and the reality widens in week five. Trump is threatening to target desalination plants — Iran's water supply — which would be a catastrophic humanitarian escalation. Iran hits the Mahshahr Special Petrochemical Zone, strikes near the Bushehr nuclear facility — which is a genuinely alarming target to be operating near — hits water desalination infrastructure and oil refinery in Kuwait. And then the IRGC publishes a list of eighteen US technology and defense companies as targets for assassination attempts. Palantir, Meta, Google, Microsoft. That's a move out of the conventional military domain entirely.
Iran's threatening to close Bab al-Mandeb too by this point. Which would be a different order of magnitude economically.
Bab al-Mandeb connects the Red Sea to the Arabian Sea and the Suez Canal route. Ten percent of global trade. If Iran activates the Houthis to close that strait as well, you're not talking about a regional energy price spike — you're talking about a fundamental disruption to global supply chains. It was a threat, not an action, by end of week five. But the threat alone was doing work diplomatically.
And then April third and fourth. Two US combat aircraft down in a single day.
This is the moment that punctures the "total air dominance" narrative most cleanly. An F-15E Strike Eagle is shot down over Iran — crew bails out, one rescued, one still being searched for. A second combat plane goes down near the Strait of Hormuz. Two aircraft in twenty-four hours. The War Zone noted explicitly that this "calls US claims of total air dominance into question." Iran's residual air defenses, particularly in mountainous terrain, were adapting. They weren't winning the air war — but they were demonstrating they hadn't lost it completely.
Running totals by end of week five: thirteen US service members killed in combat, three hundred and sixty-five wounded. Iranian Health Ministry reporting over two thousand killed. US-based rights groups putting the total closer to thirty-four hundred, including sixteen hundred civilians.
And Lebanon's toll — fifteen hundred killed, a million displaced. The Lebanese theater, which opened in week one when Hezbollah launched attacks into northern Israel, had been running in parallel the entire time. Israeli Defense Minister Katz announcing on March thirty-first that Israel would occupy Lebanese territory up to the Litani River and establish a permanent security zone. The campaign had metastasized well beyond Iran's borders.
Okay, week six. April fourth through eighth. The ceasefire week. And the diplomatic picture here is genuinely complex.
Pakistan proposes a forty-five-day two-phased ceasefire framework on April fifth. Iran rejects the US ceasefire plan on April sixth — same day Israel kills the IRGC intelligence chief Maj. Gen. Majid Khademi. Trump issues what is probably the most unfiltered presidential threat of the entire campaign: "Tuesday will be Power Plant Day, and Bridge Day, all wrapped up in one, in Iran. Open the Strait, you crazy bastards, or you'll be living in Hell." Iran responds by firing nine ballistic missiles plus fifty drones plus a cruise missile at the UAE in a single salvo. Missiles hit Tel Aviv and Haifa, killing four in a residential building.
And then April seventh — Iran rejects Pakistan's framework but proposes its own ten-point plan.
Iran's ten points are fascinating as a document of strategic intent. Continued control over Strait of Hormuz transit. Complete withdrawal of US combat forces from the region. And — the one that broke the Islamabad talks — acceptance of Iran's right to enrichment for its nuclear program. Iran is not offering to negotiate away its nuclear capability. It's offering to trade the Strait for American recognition of Iranian nuclear status.
And then April eighth, the ceasefire. Two weeks. Described by JD Vance as "fragile." Israel immediately says it doesn't apply to Lebanon and launches what it calls its largest wave of strikes on Lebanon since the start of the invasion. Iran's Foreign Minister says Hormuz passage will be allowed "via coordination with Iran's Armed Forces." Two oil tankers are allowed through — then halted because of the Israeli Lebanon strikes. The ceasefire is fragile in the most literal sense.
The ceasefire terms themselves reveal the strategic situation clearly. The Hormuz reopening is conditional and Iran-controlled. Israel is explicitly excluded. The two-week window is not a peace — it's a pause to negotiate something harder. And the Islamabad talks that followed — Vance and Iranian Parliamentary Speaker Mohammad Bagher Ghalibaf, a twenty-one-hour negotiation mediated by Pakistan — they agreed on most points except nuclear. The nuclear question is the war's unresolved core.
Let's talk about the doctrinal arc as a whole, because I think there's a really important structural observation here about what the coalition thought it was doing versus what it ended up doing.
The coalition began with a military theory of victory: destroy Iran's ability to fight, and Iran will have no choice but to negotiate. Phase one, two, three — it's all oriented around degrading military capacity. Air defenses, missile launchers, warships, production facilities. By week two, the military theory was largely vindicated. Iran's conventional military was effectively destroyed. Air force nonoperational. Surface fleet largely sunk. Sixty percent or more of missile launchers gone. Two supreme leaders killed. By any conventional military measure, Iran had lost the war by the end of week two.
And yet the war continued for four more weeks.
Because Iran had a theory of resistance that didn't depend on winning militarily. Iran's theory was: survive long enough, impose enough economic cost through the Strait, and the coalition's political will fractures before Iran does. The Strait of Hormuz was not a weapon of last resort — it was Iran's primary strategic asset the entire time. And the coalition had no clean answer to it. You can destroy every missile launcher in Iran and still not reopen the Strait without either a naval blockade or a ground invasion.
Which gets to the question of whether there was ever a coherent endgame.
This is the uncomfortable question the week-by-week analysis forces. The escalation from Phase One to Phase Two to Phase Three to Phase Four to Phase Five — each of those transitions was reactive. Iran's continued resistance prompted each next escalation. The coalition didn't walk in with a plan that said "if Iran hasn't capitulated by week three, we target steelworks." The steelworks targeting happened because Iran was still standing and the Strait was still closed. The desalination threats happened because the steelworks targeting didn't move the needle. David Ignatius at Foreign Policy described the post-ceasefire strategy as "Operation Economic Epic Fury" — which is a clever phrase, but it also suggests the military operation didn't have a clean exit built in.
Now, the deterrence collapse question. Because this is the piece that explains why the war happened at all.
Iran's True Promise One and Two missile attacks on Israel in twenty twenty-four were supposed to demonstrate Iranian deterrence — "attack us and we can hit you at home." Instead, they revealed the opposite. Haaretz's investigation found Iranian missiles were, in a direct quote, "mainly made with poorly soldered, substandard parts." One analyst asked if they were "toy missiles for kids." True Promise Two managed to land roughly forty impacts on Nevatim Air Base in Israel but caused limited damage. Foreign Policy's Decker Eveleth put it bluntly: "Had True Promise One and Two demonstrated the ability to reliably penetrate Israeli air defenses, it is unlikely Israel would have been emboldened enough to start not one, but two separate wars with Iran." The intelligence revelation that Iran's missile force was more bark than bite was the precondition for the entire campaign.
Iran's resilience in weeks three through six is then all the more striking. Because their conventional military was exposed as weaker than advertised — and yet they kept firing.
The IRGC's underground missile cities. This is a decades-long investment in survivable second-strike capability that proved more resilient than the coalition expected. Iran's geography — vast, mountainous, with a long coastline — meant there was always somewhere to hide something. Iran was still firing missiles at Haifa in week six. Not at the volume of week one, not with the same capability — but still firing. The IRGC's distributed, hardened infrastructure was the real military legacy of the Khamenei era, and it outlasted Khamenei himself.
So: diminishing returns or gathering momentum? I want to give both sides of this because I think the honest answer is different depending on which side you're analyzing.
For the coalition — gathering military momentum, diminishing political returns. Weeks one and two were extraordinary military achievements at genuinely low cost. But from week three onward, each escalation produced less strategic leverage than the previous one. Steelworks targeting didn't open the Strait. Desalination threats didn't open the Strait. Even the two downed jets in week six suggested Iran was adapting, not collapsing. The ceasefire came from mutual exhaustion and economic pressure — not from Iran's military defeat. And the economic pressure was running in both directions. The coalition's Gulf Arab partners were hurting from the Strait closure. Global energy markets were destabilized. The political cost of continuing was rising even as the military situation remained favorable.
And for Iran?
Diminishing military returns, gathering diplomatic momentum. Iran's military was devastated — there's no sugarcoating that. But it survived. Two supreme leaders killed, a third installed and hardened. Missile barrages down from two hundred plus per day to a fraction of that, yet still capable of hitting Haifa in week six. Most importantly, Iran's Strait of Hormuz leverage grew stronger as the campaign continued, not weaker. By week six, Iran was negotiating from a position of "we're still standing" — and its ten-point peace plan, maximalist as it was, was described by Trump as "a workable basis on which to negotiate." That is not the language of a nation that has been defeated. That's the language of a nation that has survived a war and is now playing for the peace.
Let's talk about what comes next. Because the ceasefire is two weeks old and the Islamabad talks broke down on the nuclear question.
The coalition's most obvious continuation is what Ignatius calls "Operation Economic Epic Fury." Trump has announced a naval blockade of the Strait of Hormuz — which is extraordinary, because the US is now blockading a waterway it was trying to keep open six weeks ago. The theory is: squeeze Iran's economy hard enough, and one of three things happens. First, the regime is overthrown — US officials apparently believe this is more likely after the bombing stops than during it, because the population can organize without wartime rally-around-the-flag dynamics. Second, Ghalibaf or another pragmatist crosses what Ignatius calls "the golden bridge" — meaning Iran accepts a comprehensive deal, sanctions removal in exchange for full nuclear, missile, and proxy renunciation. Third, IRGC hardliners escalate and force more US concessions. The Trump offer for scenario two is described as a "Tiffany deal" — a big, glittering package of economic benefits. The question is whether any Iranian leader can accept the terms and survive politically.
The nuclear question is the one that I keep coming back to. Because the war may have paradoxically accelerated Iran's nuclear calculus rather than set it back.
Eveleth makes this point explicitly, and it's the most important strategic insight of the post-ceasefire analysis. Iran now has undeniable empirical evidence that conventional deterrence failed completely. The US and Israel struck whenever they wanted, killed whoever they wanted, and Iran's conventional military couldn't stop them. The only thing that demonstrably stops the US from attacking a country is nuclear weapons. North Korea has them and hasn't been bombed. Iraq didn't have them and was invaded twice. Libya gave them up and Gaddafi was killed. The lesson is not subtle. Iran has enough enriched uranium for approximately ten weapons per Scientific American's estimates. Its nuclear facilities have taken damage but are not destroyed. The IAEA safeguards agreement has been broken. Eveleth invokes Pakistan's Zulfikar Ali Bhutto — "we will make a nuclear bomb even if it means having to eat grass" — as the framework for understanding where Iran's calculus may now be heading.
And Iran's most obvious continuation from its own perspective is nuclear deterrence as the endgame.
The ten-point plan's insistence on "acceptance of enrichment" is not a negotiating position to be traded away — it's the floor. The IRGC, which picked Mojtaba Khamenei and which has driven Iranian strategy throughout this conflict, is not going to accept a deal that leaves Iran conventionally defenseless and without a nuclear deterrent. The Bab al-Mandeb threat — activating the Houthis to close a second major shipping chokepoint — and the eighteen-company assassination list both suggest the IRGC is signaling it has escalation options it hasn't used yet. The ceasefire may be less a pause before peace and more a pause before the next phase of a longer conflict.
Pakistan as the mediator is a detail that deserves more attention than it's gotten.
Pakistan's role here is genuinely surprising. Pakistani Army Chief Field Marshal Asim Munir was credited by Iran's Foreign Minister. Pakistan is simultaneously maintaining a security relationship with Saudi Arabia — a US partner in this conflict — while hosting talks that Iran agreed to attend. That's a diplomatic tightrope that Pakistan has walked more successfully than anyone predicted. And China gets credit too — Trump explicitly said China played "a pivotal part" in persuading Iran to negotiate. The geopolitical architecture of the ceasefire is a US-brokered military victory being translated into peace through Pakistani mediation with Chinese diplomatic backing. That is a genuinely novel structure.
Alright, let me try to synthesize the whole arc. Six weeks. What does it tell us?
Here's what I think the six-week arc reveals. The coalition had a military theory of victory that was sound and executed brilliantly in weeks one and two. Iran's conventional military was destroyed faster than almost anyone predicted. But the coalition did not have a corresponding political theory of victory — a clear picture of what Iranian behavior change would constitute "winning" and how military action would produce it. Each subsequent escalation was improvised in response to Iran's refusal to capitulate on the Strait. Iran, meanwhile, had no military theory of victory — it knew it couldn't win the air war — but it had a coherent political theory of survival: stay standing, keep the Strait closed, impose economic costs, and negotiate from the position of a state that has not been conquered. That theory worked. Iran is still a state. Its nuclear program is intact. Its new Supreme Leader is a hardliner. And it's negotiating from a position that includes the Strait as a permanent bargaining chip.
The interceptor crisis as a long-term legacy point — that's the one that I think gets underweighted in the broader discussion.
The global missile defense interceptor shortage is a real structural problem that this campaign has made dramatically worse. South Korea rushing reserves to the UAE, EU states warning of shortages, Iran burning through coalition defensive capacity with drone and missile barrages — that attrition strategy has implications for every future conflict that involves precision missile attacks. The production rates for interceptors are nowhere near the consumption rates the campaign demonstrated were possible. Any adversary watching this conflict — China, Russia, North Korea — now has a validated playbook for degrading US and allied missile defense capacity through sustained attrition.
Which brings us to where things stand as of today. A two-week ceasefire that's already been tested by Israeli strikes on Lebanon. A naval blockade. Islamabad talks that got to the one-yard line and stopped at nuclear. Iran with enough enriched uranium for roughly ten weapons and the political incentive structure pointing toward deterrence, not renunciation.
Ghalibaf is the interesting variable. He's described as pragmatic by US officials — a former IRGC general who became a technocratic politician, who sat across from Vance for twenty-one hours and apparently agreed on most things. The "golden bridge" scenario — where Ghalibaf or someone like him finds a path to a deal that the IRGC accepts because the economic pain has become existential — is not implausible. But it requires the IRGC to accept a deal that leaves Iran without nuclear weapons and without conventional deterrence. That is an extraordinarily difficult internal political sell in the current environment. The more likely near-term path is continued economic pressure, continued Iranian nuclear hedging, and a fragile no-war-no-peace equilibrium that lasts until one side blinks or one side miscalculates.
Six weeks that reshaped the region, a ceasefire that may not hold, and a nuclear question that the war made harder to answer, not easier. I think that's the honest summary.
And the honest summary of the doctrine question — which is what Daniel asked — is that both sides adapted, both sides surprised the other, and neither side achieved its maximalist objectives. The coalition destroyed Iran's military. Iran kept its state, its nuclear program, and its Strait leverage. That's not a coalition victory. It's not an Iranian victory either. It's a very expensive draw with a lot of unresolved variables.
