On February 28, 2026, the United States and Israel opened the largest American air campaign in the Middle East since the 2003 invasion of Iraq. They called it Operation Epic Fury.

The first hours killed the man who had ruled Iran for thirty-six years. The fighting ran a hundred and seven days. It closed the Strait of Hormuz, gutted the command layer of the Islamic Revolutionary Guard Corps, and rearranged every relationship the United States holds in the region.

Today, a fourteen-point Memorandum of Understanding—brokered by Pakistan, signed by Trump at Versailles—is being executed. President Pezeshkian signed for Iran.

The guns are quiet.

A sixty-day window has opened to negotiate what comes next.

This is a report on where things stood before the bombing began and where they stand now. Seven questions, each asked twice. The honest bottom line, before the detail: the war changed the political and military landscape far more than it changed the thing it was launched to settle. The nuclear file is not closed. It is paused, and it is paused on terms that leave the hardest questions for another day.

A word on intent. This is a ledger, not a brief. It does not try to score the war or to take sides or assign blame—only to set down what changed, before against after, assembled from the public record.

Disputed facts are marked as disputed.

The reader can supply the politics.

The Crack in the Foundation

Begin with the flaw, because it runs under everything else.

The Memorandum was signed by President Pezeshkian and, in the electronic pre-signing, by parliamentary speaker Mohammad Bagher Ghalibaf. It was not signed by Supreme Leader Mojtaba Khamenei, and it was not signed by the man who now commands the Revolutionary Guard, Ahmad Vahidi. A senior American official noted that Supreme Leaders do not typically sign such agreements, and pointed to the 2015 nuclear deal as precedent. True as procedure. Thin as strategy—because the structure of power in Tehran today is not the structure of 2015.

On June 18, Mojtaba Khamenei issued a written statement to the Iranian people. He did not reject the deal. He did something more careful than that. He said he had held a different view as a matter of principle, but that he granted his permission because the president—as head of the Supreme National Security Council—had personally accepted responsibility for protecting the rights of the nation and the Resistance Front. In plain terms: he did not own the agreement.

He licensed it, and left himself a way out.

Meanwhile the Revolutionary Guard has not moved off its maximalist line.

IRGC-affiliated media argued through the signing that Iran should keep Hormuz closed as long as Israel fights in Lebanon—a condition found nowhere in the document’s text. Independent analysts tracking the war assess that Vahidi’s inner circle is still pressing positions that would amount, in practice, to an American surrender.

And here is the operational hinge: the IRGC Navy, not the Foreign Ministry, physically controls the Strait. Demining, the restoration of shipping lanes, the enforcement of toll-free passage—all of it depends on the compliance of the one institution that signed nothing and concedes nothing.

So the document has legal architecture and a quiet structural fault.

Whether the sixty-day window produces a settlement or collapses will turn less on the fourteen points than on a single unanswered question: whether the Supreme Leader stands behind the diplomats, or lets the Guard drive Iran’s actual conduct on the ground.

That question is genuinely open. Hold it in mind through everything that follows.

1. The Nuclear Deal

Then

The 2015 accord was already dead as a working bargain. The United States had walked away in 2018 and rebuilt its sanctions. Five rounds of indirect talks across 2025, brokered through Oman and held in Muscat and Rome, narrowed nothing that mattered. Washington wanted enrichment dismantled. Tehran called enrichment a red line and would not cross it. By early 2026 the International Atomic Energy Agency was reporting that it could no longer verify the essentials—the size of the stockpile, the state of the centrifuges, whether enrichment had been suspended at all. The last firm benchmark on the record was roughly 440 kilograms of uranium enriched to sixty percent. Enough material, taken to weapons grade, for several bombs. The inspectors had lost sight of it.

Now

The Memorandum freezes nuclear expansion for sixty days while permanent terms are negotiated. Iran reaffirms it will not build a weapon. And on the single most contested point, the United States gave ground: it dropped the demand that Iran ship its enriched material out of the country. The framework now lets Iran keep the stockpile on its own soil, to be down-blended in place under IAEA supervision—the minimum version of a mechanism still to be worked out in full.

Look hard at what did not change.

The inspectors still cannot see the material. Continuity of knowledge—the unbroken chain of observation that lets the Agency swear to where the uranium is—was severed in the 2025 strikes and has not been restored. Reporting puts more than two hundred kilograms of highly enriched material as the live subject of the talks, possibly buried in the tunnels beneath Isfahan.

The war set the program back. It did not erase it, and it did not solve the verification problem that started the crisis. The dispute simply moved—from whether Iran would return to the old deal, to whether any new deal can rebuild even a minimal floor of trust.

Dimension	Then (pre–Feb 28)	Now (June 19)
Legal framework	2015 accord defunct; sanctions rebuilt since 2018	Interim Islamabad MOU; a war-stopping pause, not a revival
Inspections	IAEA unable to verify stockpile or centrifuges	Continuity of knowledge still broken; access limited
Enrichment	~440 kg at 60%, location unverified	Not enriching; facilities damaged; material unverified
U.S. demand	Full dismantlement of enrichment	Down-blend on-site under IAEA watch; future TBD
Iran’s position	Enrichment non-negotiable	Accepts on-site down-blending; enrichment future TBD

2. The Strait of Hormuz

Then

The most important maritime chokepoint on earth, working normally. Roughly a fifth of the world’s seaborne oil moved through it every day, alongside a comparable share of liquefied natural gas. Well over a hundred ships passed daily, in both directions, under international law and free of toll, inspection, or Iranian permission. The threat was always latent—mines, anti-ship missiles, swarms of small boats—but the water was open.

Now

Within forty-eight hours of the first strikes, Iran mined the channel and declared it closed. It did not need a conventional blockade; cheap drones and mines did the work. Traffic collapsed. At the depth of the crisis only a handful of tankers a day were getting through, against a peacetime average near a hundred. Crude spiked hard before the ceasefire pulled it back down.

The Memorandum lifts the American naval blockade, commits Iran to clearing its mines, and opens a sixty-day window of toll-free passage. But physical restoration takes weeks, not hours. Mines remain in the water. Insurers are still pricing the region as exceptional risk. And buried in the text is a structural concession Tehran will not soon give back: Iran and Oman are granted joint authority to define the long-term administration of the Strait. The waterway is reopening. It is not returning to what it was.

Dimension	Then (pre–Feb 28)	Now (June 19)
Status	Open, toll-free, unrestricted	Mined, partly reopened under temporary terms
Oil flow	~20% of global seaborne crude daily	A fraction of normal; lanes still constrained
U.S. posture	Standing Gulf naval presence	Blockade lifted; mine-clearance underway
Insurance	War-risk cover routine and cheap	Premiums elevated; area treated as exceptional
Governance	International strait under transit passage	Iran–Oman granted joint administrative role

3. Iran’s Leadership

Then

One man at the top, and no ambiguity about it. Ayatollah Ali Khamenei had been Supreme Leader since 1989—the final word on the bomb, the budget, the Guard, and the foreign file. Masoud Pezeshkian, a reformist, held the presidency and operated within the space Khamenei allowed him. Power was centralized, personal, and stable.

Now

Khamenei was killed in the opening hours of February 28. Eight days later the Assembly of Experts elevated his son, Mojtaba Khamenei, to Supreme Leader—a man widely read as harder than his father, and one who has spent the months since largely hidden, citing the threat to his life. Pezeshkian remains the executive face. But real strategic authority has flattened and dispersed, shifting away from a single cleric toward a security elite operating through the Supreme National Security Council.

The personnel changed. The direction of travel changed with it. The men who rose are harder, narrower, more tightly bound to the Guard and the wartime state than the men they replaced. Succession did not crack the system open for a broader bargain. It sealed it tighter.

Role	Then (pre–Feb 28)	Now (June 19)
Supreme Leader	Ali Khamenei (since 1989)	Mojtaba Khamenei; elevated Mar 8, largely unseen
President	Masoud Pezeshkian	Masoud Pezeshkian; the diplomatic face
SNSC	Pre-war security leadership intact	Now the locus of strategic decisions
Locus of power	Centralized in one cleric	Dispersed to an IRGC-linked security elite

4. The Money

Then

No active Iran war on the books. The United States carried a standing Gulf posture and the bill for the one-off 2025 strikes, inside a defense budget already running at historic highs. Iran’s assets sat frozen under a broad sanctions architecture, its oil revenue squeezed.

Now

The war has been expensive, and the public numbers climb as the accounting widens. Pentagon officials put the direct cost near twenty-five billion dollars by late April and twenty-nine billion by mid-May. By the day of signing, reporting describes a Pentagon push for a supplemental on the order of tens of billions more to replace what the campaign burned through—munitions expended at a rate that, at the peak, ran toward two billion dollars a day. Open-source estimates put guided-munition use in the thousands in the first days alone.

On the other side of the ledger, the Memorandum hands Iran near-term relief. A first tranche of frozen funds is being unlocked to cover state salaries, with a larger sum slated for phased release across the negotiating window. The precise figures are contested between Washington and Tehran and should be read as estimates, not settled accounts. Against all of it stands Iran’s own loss: by sober estimates, war damage running near forty percent of pre-war GDP. Both sides spent enormously. Only one had its cities under the bombs.

A note on the figures: the dollar amounts above come from official briefings, mediator accounts, and war-cost trackers that do not fully agree with one another. The direction is unambiguous. The decimal points are not. Treat them as the best available reckoning on June 19, not as a closed audit.

Dimension	Then (pre–Feb 28)	Now (June 19)
U.S. war cost	None active beyond standing posture	~$25B (late Apr) → ~$29B (mid-May), climbing
Munitions	No sustained combat burn	Peak spending near $2B/day; thousands of guided rounds
Supplemental	Not required	Pentagon seeking tens of billions more
Iran’s assets	Frozen under sanctions	Phased unfreeze tied to the 60-day window
Iran’s losses	—	War damage estimated near 40% of pre-war GDP

5. The Revolutionary Guard

Then

The ideological spine of the regime and its strongest institution: ground, aerospace, and naval branches, the Basij, the Quds Force, and command of Iran’s strategic missile arm. It ran the proxy network across the region and answered, in the end, to the Supreme Leader. The European Union had just designated it a terrorist organization.

Now

Tactically gutted, politically risen. The campaign shattered the Guard’s conventional footprint—its air defenses broken, much of its navy destroyed, its naval commanders killed, a large share of its missile infrastructure gone. And yet it did not collapse, because it had prepared not to. By the account of officials who spoke to Reuters, the Guard had anticipated decapitation and pushed authority down its own ranks before the first bomb fell, naming successors several layers deep. Leaders died; the machine kept moving.

The deeper shift is political. The vacuum left by the strikes did not weaken the Guard’s position inside the state—it strengthened it. With the clerical apex thinned and the new Supreme Leader in hiding, the surviving Guard command moved to the center of decision-making through the Supreme National Security Council. “Decimated” describes the order of battle. It does not describe the politics. On the politics, the Guard is ascendant—which is precisely why its absence from the signature page matters.

Dimension	Then (pre–Feb 28)	Now (June 19)
Command	Intact, hierarchical, cleric-subordinate	Top cadre hit; pre-delegated several ranks down
Navy / air defense	Mine and swarm capability; layered defenses	Largely destroyed; Hormuz still made hazardous
Missile force	Large arsenal able to reach Israel	Roughly a third destroyed; still able to strike
Political weight	Subordinate to the Supreme Leader	Ascendant; central to the SNSC

6. Relations Across the Region

Then

Asymmetric but stable. The United States held its closest military ties with Israel and the Gulf monarchies, important working relationships with Iraq, Turkey, and Egypt, and thinner threads to Syria and Lebanon. The Gulf states, for their part, were quietly managing their own détente with Tehran—Saudi Arabia had normalized relations with Iran in 2023—and the whole region’s diplomacy bent toward avoiding exactly the war that came.

Now

The region came out of the war needing America more and trusting the arrangement less. For the first time in its history Iran struck all six Gulf Cooperation Council states—Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates—reaching past American bases to hit energy infrastructure, airports, and civilian sites. The Gulf monarchies still need American protection. They are also newly certain of their own vulnerability, and they are hedging: diversifying defense, rethinking how far to trust an American security guarantee, and reopening their own channels to a weakened Tehran.

The war widened the cracks among them as much as against Iran. The Saudi–Emirati rivalry sharpened; the UAE walked out of OPEC. The Strait split the Gulf into those who could route oil around it and those—Qatar’s gas, Kuwait, Bahrain—who could not. Further Arab normalization with Israel grew less likely, not more. And Lebanon became the open wound: the war reignited the fight with Hezbollah, displaced a vast share of the population, and split Washington from Israel over whether the ceasefire even covered it. Talks meant to follow the signing were already disrupted by renewed fighting there. That is where a paper settlement is most likely to tear.

Actor	Then (pre–Feb 28)	Now (June 19)
Gulf states	Stable U.S. ties; quiet détente with Iran	All six struck; dependent yet hedging
Israel	Closest U.S. military partner	Cooperation intact; public rift over Lebanon and the deal
Saudi–UAE	Aligned, with frictions	Rivalry sharpened; UAE exits OPEC
Lebanon	U.S. backing for state institutions	Hezbollah war reignited; core spoiler risk

7. The United States and Israel

Then

The closest military partnership the United States holds anywhere, and on Iran the two governments moved as one. They planned Operation Epic Fury together and launched it together on February 28. The aim was shared and maximalist: end Iran’s nuclear program by force, and decapitate the regime that ran it. For a decade before the war, American policy had also bent toward widening the Abraham Accords—drawing more Arab states into normalization with Israel—and that project still looked open. Alignment was close to seamless, from the targeting cells to the strategic goal.

Now

The military cooperation survived the war. The political alignment did not survive the peace. Trump signed a Memorandum that Prime Minister Netanyahu disputes, and the seam between Washington and Jerusalem opened in public. The sharpest break is Lebanon: when the United States moved to end the fighting, Israel kept striking, and the two governments split openly over whether the ceasefire with Iran even covered the Lebanese front. Trump publicly criticized Israeli operations there as too costly in civilian lives—a rare daylight rebuke of the closest ally.

The deeper damage is to the project the alliance was built to advance. Rather than widening normalization, the war made further Arab–Israel rapprochement less likely, not more—Gulf publics watched Iranian missiles fall on their own cities in a war Israel helped start, and the appetite for drawing closer to Jerusalem cooled. So the ledger reads two ways at once: the operational partnership proved it could fight a war together, and the political partnership came out of that war more strained than it has been in years, with its signature diplomatic ambition set back. For a report on the American position, this is not a footnote. It is one of the war’s central costs.

Dimension	Then (pre–Feb 28)	Now (June 19)
Strategic aim	Shared, maximalist: end the program by force	Diverged: U.S. took the deal; Israel disputes it
Military cooperation	Joint planning; launched Epic Fury together	Intact; the operational partnership held
Lebanon	Aligned posture	Open split over whether the ceasefire covers it
Normalization	Abraham Accords expansion still open	Further Arab–Israel normalization less likely

What the War Settled, and What It Did Not

Set the two pictures side by side and the shape of it is clear.

A war launched to end a nuclear threat ends with the nuclear material still in the ground, still unwatched, still unresolved—moved from one negotiating table to another. What the war did change, it changed brutally and perhaps permanently: a thirty-six-year ruler dead, his program in rubble, his Guard’s fleet on the bottom, his region’s every alignment knocked loose from its old moorings.

The Memorandum signed today is a real achievement. The guns are silent and the Strait is opening. But it rests on a fault that no signature ceremony can paper over. The men who hold the actual power in Tehran—the Supreme Leader who handed off the accountability, the Guard that controls the water and signed nothing—have not bound themselves to it. A deal is only as durable as the parties who must carry it out, and the party that must carry out the hardest part of this one has spent the week telling anyone listening that it does not consider itself bound.

Then and now, the same truth holds, only sharper for the bloodshed: in Iran, the question was never what the diplomats would sign. It was always who, behind them, actually decides. Four months of war answered a great many questions. It did not answer that one.

The pattern is plain. The war changed the map of the region and left untouched the one question it was launched to answer—whether Iran will build the bomb.

The man who ruled for thirty-six years is dead.

His Guard was gutted in the field and, in the same stroke, raised up in the palace.

The Strait is open again and no longer fully his.

Israel, seamless going in, came out strained.

And the enriched uranium is still in the ground, still unwatched, waiting on a deal that the men who hold the guns in Tehran have not signed.

That is Iran on in late June: the map changed, and the question did not.
