Yes, Iran had agreed to never stockpile enriched uranium — a diplomatic breakthrough announced by Oman’s Foreign Minister Badr bin Hamad Al Busaidi on February 28, 2026 — just hours before the United States and Israel launched large-scale military strikes on Tehran and multiple other Iranian cities. The agreement, described as “zero stockpiling,” included Iran’s commitment to degrade its existing uranium reserves to the lowest level possible through an irreversible conversion process, with full IAEA verification. It was, by any reasonable diplomatic standard, a major concession from Tehran. And it was rendered meaningless within hours by a coordinated bombing campaign involving approximately 200 Israeli fighter jets and American B-2 stealth bombers.
The timing raises a question that no official in Washington or Jerusalem has adequately answered: if a deal was “within reach,” as Oman’s foreign minister put it, why were the bombs already in the air? The strikes killed at least 201 people in Iran, including 148 in a single hit on a girls’ elementary school in Hormozgan province. Iran’s Supreme Leader Ali Khamenei was reportedly killed. Three American soldiers and at least nine Israelis died in retaliatory strikes. This article examines the diplomatic agreement Iran accepted, the military operation that followed the same day, the human cost, and what this sequence of events means for American credibility in future negotiations.

What Exactly Did Iran Agree to Before the Strikes Began?
The deal Iran accepted was not a vague gesture toward future talks. According to Oman’s Foreign Minister Al Busaidi, who brokered the indirect negotiations, Iran agreed to “zero stockpiling” of enriched uranium — meaning the country would never maintain reserves of nuclear material sufficient to build a weapon. Al Busaidi stated plainly: “The single most important achievement, I believe, is the agreement that Iran will never ever have nuclear material that will create a bomb.” Iran further agreed to degrade its current stockpile — approximately 400 kilograms of uranium enriched to 60% U-235, which is near weapons-grade — by converting it into reactor fuel through an irreversible process. This was not a handshake promise. The framework included full and comprehensive verification by the International Atomic Energy Agency, the same body that monitored Iranian compliance under the 2015 JCPOA. For context, the 2015 deal allowed Iran to maintain a stockpile of 300 kilograms of low-enriched uranium.
The February 2026 agreement went significantly further — no stockpile at all, verified internationally. The Arms Control Association described the trump administration’s broader approach as “chaotic and reckless,” but the concession Iran put on the table was arguably more restrictive than anything achieved in previous rounds of diplomacy. Al Busaidi indicated that a comprehensive deal could be finalized “amicably and comprehensively” within a few months. The U.S. and Iran had been conducting indirect talks through Oman, including sessions in Geneva in late February. CNBC described the February 27 round as the “most intense” nuclear negotiations to date. No formal agreement was signed — but the framework Iran accepted addressed what had long been the central sticking point in every nuclear negotiation since 2003.
The Military Strikes — What Happened on February 28, 2026
On the same day Oman’s foreign minister announced the diplomatic breakthrough, the united states and Israel launched a coordinated military assault on Iran. Israel deployed approximately 200 fighter jets in what was described as the largest military flyover in Israeli Air Force history. U.S. B-2 stealth bombers armed with 2,000-pound bunker-buster bombs struck Iran’s ballistic missile facilities. The targets spanned multiple cities, including Tehran, Tabriz, Qom, Isfahan, Kermanshah, and Karaj. Strikes hit areas near the offices of Supreme Leader Ali Khamenei and President Masoud Pezeshkian. NBC News reported that Khamenei was killed in the attacks, along with several high-ranking Iranian officials. However, the scope of leadership casualties and the full extent of infrastructure damage remain difficult to verify independently in the immediate aftermath of a military operation of this scale.
What is clear is that this was not a surgical, limited strike — it was a campaign hitting targets across the country’s geography and political infrastructure. The critical question is one of timing and intent. Trump had set an early March deadline for reaching a nuclear agreement. The February 27 talks ended without a signed deal, but with Iran’s agreement to the zero-stockpiling framework announced the very next day. A military operation involving 200 fighter jets and intercontinental stealth bombers is not planned in 24 hours. The logistics, target packages, and coordination between U.S. and Israeli forces had clearly been in motion for weeks, if not months, before the diplomatic announcement. This suggests the strikes were proceeding on their own timeline regardless of what happened at the negotiating table.
The Human Cost — Casualties and Civilian Impact
The preliminary death toll as of March 1, 2026, stood at 201 killed in Iran. The single deadliest strike hit a girls’ elementary school in Hormozgan province, killing 148 people — overwhelmingly children and educators. That number alone exceeds the total casualty count in most modern U.S. military engagements that receive sustained media coverage. On the other side, Iranian retaliatory strikes killed at least nine people in Israel and three U.S. soldiers.
These deaths are equally real, equally tragic, and represent the cost of a decision to escalate rather than negotiate. The families of those three American service members are now living with the consequence of a policy choice made by political leaders who were, by all available evidence, presented with a viable diplomatic alternative. Al Jazeera’s live death toll tracker indicated these numbers were preliminary, and the actual count was expected to rise as rescue operations continued and rubble was cleared from bombed sites. The strike on the school in Hormozgan warrants particular attention because it undercuts the narrative that these were precision strikes targeting military and nuclear infrastructure. Hitting an elementary school — regardless of the reason — is the kind of event that defines a military operation in the eyes of the world. It is also the kind of event that generates exactly the kind of blowback and radicalization that nuclear negotiations are designed to prevent.
Diplomacy Versus Military Action — The Tradeoffs the Administration Chose
The Trump administration faced a genuine policy choice. On one hand, Iran had offered the most sweeping nuclear concession in the history of U.S.-Iran relations — zero stockpiling with irreversible degradation and international verification. On the other hand, military planners had prepared a strike package designed to destroy Iran’s ballistic missile capacity and decapitate its leadership. The administration chose both, which in practice meant choosing the bombs. Consider the comparison. The 2015 JCPOA, negotiated under Obama and abandoned by Trump in 2018, allowed Iran to maintain limited enrichment capabilities and a 300-kilogram low-enriched uranium stockpile. Critics, including Trump, called that deal too weak. The February 2026 framework addressed every major criticism: no stockpile at all, IAEA verification, and irreversible degradation of existing material.
It was the deal that hawkish critics had said they wanted — and it was discarded without a signature. The tradeoff is not abstract. Military strikes can destroy facilities, but they cannot destroy knowledge. Iran’s nuclear scientists — those who survived — still know how to enrich uranium. Centrifuge designs can be rebuilt. The difference is that before February 28, Iran was at the table offering permanent concessions. After February 28, every incentive for any future Iranian government to negotiate in good faith has been demolished. The lesson delivered to Tehran, and to every other nation watching, is that American diplomacy is not a process to be trusted, because the bombs may already be on their way while the talks are still underway.
What This Means for Future Nuclear Negotiations
The February 28 sequence creates a precedent problem that will outlast the current administration. North Korea, which has observed every U.S. interaction with Iran since 2003, now has a concrete example of a nation making maximum concessions and being bombed the same day. Any future attempt to negotiate denuclearization with Pyongyang will run headlong into this precedent. The same applies to any emerging nuclear state or aspirant. The Arms Control Association characterized Trump’s broader Iran nuclear policy as “chaotic and reckless.” That assessment, however critical, may understate the structural damage.
International arms control is built on a basic premise: that states can trade away weapons capability in exchange for security guarantees. February 28 demonstrated the opposite — that trading away capability gets you bombed. This is not a theoretical concern. It is now a data point that every foreign ministry and military command on the planet will incorporate into its strategic calculations. There is also a domestic credibility issue. The Times of Israel reported on the “decisive hours” in which progress on a deal appeared to coincide with a countdown to strikes. If the administration was negotiating in good faith while simultaneously preparing a military operation, it raises questions about whether the diplomatic track was ever genuine or whether it served primarily as political cover — a way to say “we tried” before launching an operation that had been planned for weeks.
The Role of Oman and Third-Party Mediation
Oman’s role as a mediator deserves recognition precisely because it was successful — and then rendered irrelevant. Oman has historically served as a quiet diplomatic channel between the United States and Iran, including during the secret talks that preceded the 2015 JCPOA. Foreign Minister Al Busaidi’s announcement on February 28 reflected genuine diplomatic work: shuttle negotiations, confidence-building, and the patient construction of a framework both sides could accept.
The destruction of that framework on the same day it was announced does not only affect U.S.-Iran relations. It damages the credibility of third-party mediation as a tool of conflict resolution. Oman put its diplomatic reputation on the line to broker these talks. Other potential mediators — Qatar, Switzerland, Norway — will think twice before investing similar effort if the result can be obliterated by a strike package that was being assembled while the mediator was still at the table.
Where This Goes From Here
The immediate future is defined by escalation risk. Iran launched retaliatory strikes that killed at least nine people in Israel and three U.S. soldiers. The question is whether this cycle continues or whether some off-ramp emerges. With Iran’s supreme leader reportedly dead and its political leadership targeted, the country’s decision-making structure is in flux.
There is no clear counterpart for any future negotiation, which may have been part of the strategic calculus. Longer term, the February 28 events will be studied alongside the Iraq War as a case study in what happens when military timelines override diplomatic ones. The difference here is sharper: Iran was not accused of having weapons of mass destruction that did not exist. Iran had an actual enrichment program, and it was actively agreeing to dismantle it. The bombs fell anyway. Whatever comes next — a broader regional war, a fractured Iran, a new nuclear arms race in the Middle East — will trace part of its origin to the decision made on that single day in February 2026.
Conclusion
The facts are not in dispute. On February 28, 2026, Iran agreed to never stockpile enriched uranium, to degrade its existing reserves irreversibly, and to submit to full IAEA verification. Oman’s foreign minister announced the framework publicly and stated a comprehensive deal was within reach. On the same day, the United States and Israel launched a massive air campaign that killed at least 201 people in Iran, including 148 at a girls’ elementary school, struck targets across six cities, and reportedly killed Iran’s supreme leader. Three American soldiers and nine Israelis died in retaliation.
The question this leaves is not really about Iran’s nuclear program. It is about whether the United States can be trusted to negotiate. Every future arms control discussion, every diplomatic overture, every mediator’s effort now carries the weight of February 28. A nation agreed to the terms being demanded of it and was bombed hours later. That is not a fact that can be explained away with talking points about “maximum pressure.” It is a fact that will shape geopolitics for a generation.
