The Road to the Unthinkable: 2026 Will See The Nuclear War

The Road to the Unthinkable: 2026 Will See The Nuclear War Part 1/5: The Negotiations That Never Had a Chance A five-part investigative series on the US-Israel war against Iran, the death of diplomacy, and the path toward nuclear catastrophe. Published March 24, 2026 On the evening of February 27, 2026, Oman’s Foreign Minister Badr bin Hamad Al Busaidi stood before a cluster of reporters in Geneva and said something that hadn’t been said about the Iranian nuclear crisis in years. He said that Iran had agreed, during the third round of indirect talks with the United States, to a fundamental concession: it would never stockpile enriched uranium. He described the development as a major breakthrough. He said that all remaining issues between Washington and Tehran could be resolved “amicably and comprehensively” within a few months. The UK’s National Security Adviser Jonathan Powell, who had been secretly attending the negotiations, reportedly shared a similar assessment, telling London that a diplomatic resolution was within reach. Operation Epic Fury Less than twenty-four hours later, the United States and Israel launched a coordinated military assault on Iran. Operation Epic Fury, as the White House named it, began before dawn on February 28 with waves of cruise missiles and airstrikes targeting military installations, government buildings, and leadership compounds across the country. Supreme Leader Ali Khamenei was killed in the opening hours. His death was confirmed by Iranian state media on March 1. The diplomatic breakthrough announced the previous evening was, in effect, answered with a Tomahawk missile. This first installment of a five-part series traces the diplomatic history that led to this moment: from the 2018 withdrawal from the Iran nuclear deal, through the slow collapse of every off-ramp that might have prevented a war, to the final hours in Geneva when peace was declared achievable and then abandoned. The purpose is not editorial. It is evidentiary. The question is straightforward: was this war the product of failed diplomacy, or was diplomacy itself never permitted to succeed? The JCPOA: What Was Surrendered in 2018 To understand what was destroyed in February 2026, it is necessary to understand what existed before. The Joint Comprehensive Plan of Action, negotiated in 2015 between Iran and six world powers (the US, UK, France, Germany, Russia, and China), was the most comprehensive nuclear nonproliferation agreement achieved through multilateral diplomacy in decades. Under its terms, Iran agreed to reduce its stockpile of enriched uranium by 98 percent, limit enrichment to 3.67 percent (far below the 90 percent weapons-grade threshold), disable two-thirds of its centrifuges, convert its heavy-water reactor at Arak so it could not produce weapons-grade plutonium, and submit to the most intrusive international inspection regime ever applied to a sovereign nation. In exchange, the international community lifted nuclear-related sanctions. The agreement was not based on trust. It was based on verification. The IAEA conducted over 3,000 inspector-days in Iran in the years following the deal’s implementation and consistently certified Iranian compliance. Withdrawal from JCPOA On May 8, 2018, Donald Trump withdrew the United States from the JCPOA. His stated reasons shifted depending on the audience: the deal was “terrible,” it didn’t address Iran’s ballistic missile program, it contained sunset clauses that would eventually expire, and Iran was a bad actor in the region. He did not claim that Iran had violated the agreement. The IAEA had certified Iran’s compliance eleven consecutive times. European allies, who were parties to the deal, responded with what the leaders of France, Germany, and the United Kingdom jointly described as “regret and concern.” French President Emmanuel Macron had warned Trump explicitly, telling Der Spiegel that withdrawing from the deal could lead to war. The withdrawal was not a policy correction. It was an act of demolition. The JCPOA had been the product of years of painstaking multilateral negotiation, and its abandonment did not come with a replacement framework. In its place, the Trump administration announced a “maximum pressure” campaign: comprehensive economic sanctions intended to force Iran into a new, broader agreement that would address not only its nuclear program but also its ballistic missiles, its regional proxy networks, and its human rights record. The implicit theory was that enough economic pain would compel Tehran to capitulate. The theory was wrong. It had been tested in various forms for decades and had never produced the desired result. What it produced instead was entirely predictable. The Enrichment Spiral: 2019–2025 Iran’s response to the US withdrawal unfolded in stages, each one a deliberate step away from the constraints it had voluntarily accepted under the JCPOA. The sequence matters because it demonstrates a direct causal chain between the abandonment of the deal and the nuclear crisis that eventually served as the stated justification for military action. In July 2019, Iran increased its uranium enrichment from the JCPOA-mandated 3.67 percent to 4.5 percent. By November 2019, it had begun enriching at the Fordow facility, which the JCPOA had converted to a research-only site. In December 2020, Iran resumed enrichment to 20 percent. In April 2021, it crossed a critical threshold: enrichment to 60 percent, the highest level Iran had ever achieved and a level that has no plausible civilian application. Each escalation was framed by Tehran as a response to the US withdrawal and as leverage for future negotiations. Whether one accepts that framing or views it as opportunistic is a matter of interpretation. What is not a matter of interpretation is the trajectory. Under the JCPOA, Iran’s breakout timeline, the time required to produce enough fissile material for a single nuclear weapon, was estimated at twelve months or more. By 2022, that timeline had collapsed. The Institute for Science and International Security assessed Iran’s breakout at “zero,” meaning it possessed enough enriched material and centrifuge capacity to produce weapons-grade uranium in a matter of days. 2025 By early 2025, the IAEA reported that Iran had accumulated over 408 kilograms of uranium enriched to 60 percent purity, a nearly 50 percent increase from the previous reporting period. At this concentration, the material was a relatively simple technical step away from weapons-grade 90 percent enrichment. Analysts at the Institute for Science and International Security estimated that Iran could produce enough weapons-grade material for five to six nuclear weapons in less than two weeks. None of this would have been possible under the JCPOA. The agreement had capped Iran’s enriched uranium stockpile at 300 kilograms of material enriched to no more than 3.67 percent. The stockpile that existed in early 2025, over 400 kilograms at 60 percent, represented the direct and measurable consequence of the 2018 withdrawal. This is not a partisan observation. It is a factual chain of events documented by the IAEA, analyzed by independent nonproliferation experts, and acknowledged even by hawkish analysts who supported the original withdrawal. The policy of maximum pressure was supposed to produce a better deal. Instead, it produced a more advanced nuclear program, a shorter breakout timeline, and the very crisis that would later be cited as justification for war. The Twelve-Day War: June 2025 The first major military escalation came not from the United States but from Israel. On June 13, 2025, the Israeli Air Force launched a surprise attack on Iranian nuclear and military facilities, deploying more than 200 fighter jets in five waves of airstrikes that dropped over 330 munitions on approximately 100 targets. The operation assassinated prominent military leaders and nuclear scientists, destroyed or damaged air defense systems, and struck nuclear infrastructure across the country. Iran retaliated with over 550 ballistic missiles and more than 1,000 suicide drones, hitting civilian population centers, at least one hospital, and more than a dozen military and government installations in Israel. The United States intercepted some of the Iranian attacks and directly bombed three Iranian nuclear sites on June 22. A ceasefire was reached on June 24 under US pressure. What did 12 day war accomplish The Twelve-Day War accomplished two things. First, it demonstrated that Israel could reach deep into Iranian territory and inflict significant damage on hardened military targets. Second, it demonstrated that Iran could absorb such an attack and respond with a volume of fire that overwhelmed Israeli air defenses in multiple locations. The war did not resolve the nuclear question. It accelerated it. Iran emerged from the ceasefire with its enrichment infrastructure damaged but not destroyed, its leadership intact, and a demonstrated willingness to absorb enormous punishment without capitulating. The ceasefire was supposed to create space for renewed diplomacy. For the remainder of 2025, no formal negotiations took place. The parties communicated through third-party intermediaries and public statements. The diplomatic window was technically open, but no one walked through it. The 2025–2026 Iranian Protests and the Maximum Pressure Endgame In late December 2025, Iran experienced the largest popular uprising since the 1979 Islamic Revolution. The immediate trigger was economic: a sharp depreciation of the Iranian rial, hyperinflation, and widespread shortages linked to the compounding effects of international sanctions and government mismanagement. But the scale of the protests, which spread to over 200 cities within days, reflected something deeper: a population that had been ground down by decades of authoritarian governance, seven years of crippling sanctions that followed the US withdrawal from the JCPOA, and the physical and psychological toll of the June 2025 war. The Iranian government’s response was catastrophic. On January 3, 2026, Supreme Leader Khamenei denounced the protesters as “rioters” who should be “put in their place.” Between January 8 and 9, security forces, reportedly acting under direct orders from Khamenei and senior officials, opened fire on demonstrators in multiple cities simultaneously. The death toll from these two days alone ran into the thousands. By late January, estimates ranged from approximately 7,000 to upward of 36,500 killed, making the crackdown the largest mass killing of civilians by their own government in modern Iranian history. Amnesty International documented the killings extensively. Iranian authorities imposed a near-total internet shutdown to limit the flow of information. For the Trump administration, the protests and the massacres presented both an opportunity and a decision point. On one hand, the internal crisis weakened the Iranian government and arguably strengthened the US negotiating position. On the other, it created political pressure for a more aggressive response. Trump chose the aggressive path. In January 2026, he announced the largest US military buildup in the Middle East since the 2003 invasion of Iraq, positioning carrier strike groups, additional air assets, and ground force elements across the region. The buildup was publicly framed as a response to the massacres, but its scale and composition were consistent with preparations for offensive operations, not humanitarian intervention. The Geneva Talks: February 2026 Against this backdrop, indirect negotiations resumed. On February 4, 2026, following lobbying by Arab leaders concerned about regional stability, the White House agreed to re-engage diplomatically with Iran through Omani mediation. The talks were indirect: US and Iranian negotiators occupied separate rooms, with Omani diplomats shuttling between them. The first round took place in Muscat on February 6. A US military commander was present alongside the diplomatic team, an unusual inclusion that signaled both the seriousness of the engagement and the implicit threat behind it. The talks were described by both sides as productive. Iran and the US agreed to continue negotiations. A second round was held in Geneva on February 17. The Soufan Center described the results as “mixed,” noting that while Iran was willing to discuss limits on enrichment, the US demanded were broader than what Tehran was prepared to concede on issues like ballistic missiles and regional proxy activity. The third and most intensive round took place on February 26 in Geneva. It was during this session that the Omani mediators secured what they described as Iran’s agreement to never stockpile enriched uranium, the concession that Foreign Minister Al Busaidi announced publicly on February 27. Technical-level discussions were scheduled to continue in Vienna. Meanwhile, reporting by The Washington Post indicated that the Trump administration was simultaneously weighing military action against Iran even as the diplomatic track proceeded. The article, published on February 26 (the same day as the third round of talks), described an internal debate within the White House between those who favored giving diplomacy more time and those who argued that the moment was ripe for a decisive military strike. The Arms Control Association later published an analysis titled “US Negotiators Were Ill-Prepared for Serious Nuclear Negotiations,” concluding that the American diplomatic team lacked both the technical expertise and the institutional mandate necessary to reach a meaningful agreement. The implication was stark: the negotiations may have been designed to fail, or at minimum were not staffed or supported at a level consistent with genuine intent to reach a deal. February 28: The Day Diplomacy Died On the morning of February 28, 2026, less than twenty-four hours after the Omani Foreign Minister told the world that peace was within reach, Donald Trump told reporters that he was “not exactly happy with the way they’re negotiating.” That statement was the last diplomatic communication before the missiles. The timing demands scrutiny. The Omani mediator had just announced a major Iranian concession. The UK’s secret envoy had reportedly assessed that a deal was achievable. Technical discussions were scheduled to continue in Vienna. And then, between Trump’s expression of dissatisfaction and the next sunrise, the United States and Israel launched the most intensive military operation in the Middle East since the 2003 invasion of Iraq. The negotiations and talks were just a ruse. Operation Epic Fury began before dawn. The US component involved cruise missiles launched from naval vessels in the Persian Gulf and Arabian Sea, B-2 stealth bomber sorties, and strikes from carrier-based aircraft. Israel’s parallel operation, codenamed Operation Roaring Lion, deployed its air force for deep-strike missions against Iranian military and nuclear targets. The opening phase targeted senior Iranian leadership, missile infrastructure, air defense networks, and nuclear facilities. Within hours, Supreme Leader Khamenei was dead. His compound had been destroyed. Multiple senior military and intelligence officials were killed. The Iranian Atomic Energy Organization’s facilities were struck. The Ministry of Intelligence, the Ministry of Defense, and the military base at Parchin were all hit. Over the first seven days, US forces alone struck more than 3,000 targets across Iran. By day ten, the number had exceeded 5,000. Trump announced the operation on Truth Social, outlining four objectives: preventing Iran from acquiring a nuclear weapon, destroying its missile arsenal and production capacity, degrading its proxy terror networks, and annihilating its navy. The White House published a fact sheet titled “Peace Through Strength: President Trump Launches Operation Epic Fury to Crush Iranian Regime, End Nuclear Threat.” Iran’s response was immediate and massive. Within hours of the first strikes, the Islamic Revolutionary Guard Corps launched ballistic missiles and drone swarms against US military positions across the region and against targets in Israel, Saudi Arabia, and other Gulf states. By March 5, Iran reported having fired over 500 ballistic and naval missiles and approximately 2,000 drones. The war had begun. What the Record Shows The diplomatic record from 2018 to February 28, 2026, tells a story that is not ambiguous. It begins with the voluntary dismantlement of a functioning nonproliferation agreement. It continues through years of escalating sanctions that failed to produce a new deal but succeeded in accelerating Iran’s nuclear program. It passes through a brief, violent war in June 2025 that damaged but did not destroy Iranian nuclear capabilities. It arrives at a renewed diplomatic effort in early 2026 that, by the account of the mediators themselves, was producing results. And then, on the morning of February 28, with the mediator’s announcement of a breakthrough still fresh, with technical talks scheduled to continue, with the UK’s national security adviser apparently optimistic, the bombs fell. The question is not whether the Iranian nuclear program represented a genuine security concern. It did. The question is not whether the Khamenei regime was brutal. The January massacres demonstrated that beyond any doubt. The question is whether the decision to launch a full-scale military assault at the precise moment when diplomatic progress was being reported constitutes a deliberate choice to pursue war over peace. The evidence points to yes. The Arms Control Association concluded that the US negotiators were ill-prepared for serious nuclear talks. The Washington Post reported that the White House was weighing military options concurrently with the diplomatic track. The gap between the announced breakthrough and the first strike was less than a single day. No additional demands were made. No ultimatum was issued. No diplomatic off-ramp was offered or exhausted. This was not a war that began because negotiations failed. The negotiations did not fail. They were abandoned. And they were abandoned not after an Iranian provocation, not after a collapsed deal, not after an exhausted diplomatic process, but after a mediator said the word “breakthrough.” The people who decided to bomb Iran on February 28, 2026, did so with full knowledge that an alternative path existed. They chose the bombs anyway. The question that the remaining four parts of this series will attempt to answer is: why? And at what cost? Part 2/5: “Operation Epic Fury and the First 24 Days” will examine the military campaign, its conduct, its casualties, and the Minab school bombing that killed over 110–160 children on day one of the war. I cried myself to sleep.
