The United States-Iran war began on February 28, 2026, and ended — in its formal declaration — on June 15, 2026. One hundred and nine days. Here is the complete accounting of what that period cost and what it produced: in lives, in economics, in geopolitics, and in the unanswered questions that the peace deal’s follow-on process will have to address.
The agreement is intended to bring a halt to the U.S. and Israel’s war against Iran, which began Feb. 28, marked by the killing of Supreme Leader Ayatollah Ali Khamenei and U.S.-Israeli strikes across Iran.
The war began in the pre-dawn hours of February 28 with coordinated US and Israeli air strikes that killed Iran’s Supreme Leader and struck across Iran’s military and nuclear infrastructure. It ended in the evening of June 15 with a Truth Social post and a diplomatic announcement from Islamabad. The 109 days between those two moments are a complete story — one that changed the Middle East, the global economy, and the international order in ways that will not be fully understood for years.
Here is what can be assessed now.
The Human Cost
The full human cost of the Iran war will not be known for years. Official death tolls in conflicts are typically undercounts — particularly for civilian deaths in areas of active combat where documentation is incomplete and independent access is limited.
What can be documented:
In Iran: Thousands of Iranians died in the initial February 28 strikes and the subsequent 109 days of US air operations. The strikes targeted military infrastructure, but the scale and intensity of the campaign — 49 Tomahawks in a single night, 90 targets on Kharg Island alone — produced casualties among military personnel and civilians in proximity to targeted sites. Supreme Leader Khamenei was killed. IRGC commanders died in command centre strikes.
In the Gulf states: Kuwait bore the most direct civilian cost — its international airport struck twice, one person killed in the June 3 attack, scores injured. Iranian ballistic missiles targeted Kuwait, Bahrain, and Jordan on multiple occasions. US and Kuwaiti air defences intercepted the vast majority, but debris from intercepted missiles fell over Kuwaiti residential areas.
In Lebanon: Seven UNIFIL peacekeepers — from Serbia, Indonesia, France, El Salvador, and Spain — were killed in the Lebanon front that escalated alongside the Iran war. Lebanese civilians died in Israeli air strikes throughout the conflict period. The final Lebanese civilian casualty count from the conflict period has not been published.
At sea: Three Indian sailors died when a tanker was struck in the Gulf of Oman during the exchange of fire in mid-June. A US Army AH-64 Apache helicopter was downed — the first US military aircraft lost in the conflict.
Political executions inside Iran: At least 31 people were executed inside Iran during the first 65 days of the war on political or security charges — an acceleration of Iran’s already-elevated execution rate that rights groups linked to the conflict’s domestic political dynamics.
The Economic Cost
The deal, scheduled to be formally signed Friday in Switzerland, marks a major breakthrough in the conflict that set the Middle East aflame and shook the global economy.
The economic damage of the Iran war is measurable and specific:
Oil prices: Brent crude rose above $100 per barrel in mid-March and remained there for more than 85 days. It peaked above $115 following the Kharg Island strikes on June 13. The IEA characterised the situation as “the most severe oil supply shock in history.”
US inflation: US annual inflation rose from 2.4% in February (before the war) to 3.3% in March, 3.8% in April, and 4.2% in May — the highest since April 2023. Core inflation also rose, indicating that energy price increases had spread through the broader economy.
US gas prices: National average gasoline prices rose above $4.42 per gallon in late May and above $4.56 by mid-June — levels not seen since 2022.
Shipping costs: War risk insurance premiums for Gulf shipping rose to four to five times pre-war levels. Ships rerouted via the Cape of Good Hope added 10-14 days to Asia-Europe transit times and significant additional fuel costs.
Iran’s losses: The US naval blockade cost Iran an estimated $500 million per day in lost oil export revenues. Over 109 days, that represents approximately $54.5 billion in cumulative losses — before accounting for the physical destruction of military infrastructure.
Global impact: The IEA April 2026 report described the situation as the most severe oil supply shock in history. Central banks worldwide were forced to reassess inflation trajectories. Global economic growth projections were revised downward.
What the US Won
The United States entered the war with stated objectives: eliminate or significantly constrain Iran’s nuclear programme, and restore freedom of navigation in the Strait of Hormuz. Assessing what was actually achieved against those objectives:
Military degradation: Iran’s navy was largely destroyed. Its air force was significantly degraded. Command and control infrastructure was repeatedly struck. Radar installations, missile storage facilities, and IRGC headquarters across Iran were hit in 109 days of strikes.
Nuclear infrastructure: The February 28 strikes and subsequent operations damaged significant elements of Iran’s nuclear programme. The full extent of the damage — particularly to underground facilities like Fordow — was never publicly confirmed, but assessments suggested significant setback.
Supreme Leader killed: The killing of Ali Khamenei — the figure who had run the Islamic Republic for more than three decades — was the most strategically significant single event of the war. It created a succession crisis that complicated Iran’s decision-making throughout the conflict.
Nuclear commitments in the deal: Iran committed to never seeking nuclear weapons, an enrichment moratorium (12-15 years, details to be finalised), IAEA snap inspections, and no underground nuclear facilities. These are significant constraints that go beyond the original JCPOA in several respects.
Hormuz reopened: The most immediate goal — restoring freedom of navigation through the Strait of Hormuz — is being achieved through the deal’s implementation.
Lebanon included: Including Lebanon in the ceasefire framework — something Iran demanded and the US initially resisted — was achieved in a formulation that both sides accepted.
What Iran Retained
Iran entered the war in a position of massive conventional military inferiority. That asymmetry defined the conflict’s military character: the US could bomb wherever it chose, and Iran could not prevent it. What Iran achieved in 109 days is the product of that constraint:
Government continuity: Iran’s government survived. The Islamic Republic, as a political and social structure, was not overthrown. Mojtaba Khamenei became Supreme Leader and the system continued.
Enrichment rights preserved (partially): The moratorium is not a permanent ban. Iran retains the right to enrich uranium after the moratorium expires — a principle it never conceded throughout the negotiation.
Missile programme untouched: Iran’s ballistic missile programme — its most significant remaining deterrent — is not addressed in the MOU. It will go into follow-on talks where Iran has already declared it will not negotiate on missiles.
Hezbollah network constrained but not eliminated: The Lebanon ceasefire constrains Hezbollah’s immediate operations. It does not disarm Hezbollah, remove its weapons, or eliminate the network of tunnels, launch sites, and missile arsenals that Israel was trying to degrade during the conflict.
Financial relief: The release of $25 billion or more in frozen assets — and the potential for a larger reconstruction fund if the follow-on talks succeed — provides Iran with financial relief from the economic devastation of the blockade.
What Was Not Resolved
The peace deal ends the war. It does not resolve the problems that caused the war or all of the problems the war created.
The nuclear follow-on: The enrichment moratorium duration, dismantlement modalities, and inspections specifics go into 60-day follow-on talks. Those talks will be the most technically complex diplomacy of the post-war period. They can fail. If they fail, the MOU’s nuclear constraints remain in a disputed state.
Iran’s missiles: The missile programme is not on any table. Iran has been explicit and consistent. This is not resolved.
Lebanon’s durability: Hezbollah has not formally accepted the ceasefire. Whether the Lebanon front goes quiet depends on Hezbollah’s decision, which depends on Iran’s ability to deliver its proxy’s compliance — something that is not guaranteed.
North Korea: Kim Jong Un expanded his nuclear programme throughout the 109 days of the Iran war. The deal does not change that. The attention that returns to North Korea when the Iran follow-on talks begin will find a country that used the silence well.
Sudan: The RSF has been killing civilians throughout the 109 days. The peace deal does not include Sudan. The world’s most severe humanitarian crisis continues.
The Verdict
The Iran war of 2026 was a war that neither side fully won and neither side fully lost. The United States achieved military dominance over Iran’s conventional forces and extracted nuclear concessions that go beyond the 2015 JCPOA. Iran survived as a state, preserved some enrichment rights, kept its missile programme, and extracted financial relief and a Lebanon ceasefire inclusion that Iran’s hardliners can present as evidence of resistance.
US Vice President JD Vance said the newly announced ceasefire could usher in a “new era” for the Middle East. He credited Trump’s diplomacy with Gulf countries and other regional partners for helping bring about the deal. “What the president has done is create the real space to transform that region,” Vance said in an interview with Fox News. “And now, hopefully, a new era with the Iranians.”
Whether Vance’s “new era” characterisation proves accurate or aspirational depends on what the follow-on talks produce. A durable nuclear agreement, genuinely verified and enforced, would represent the most significant non-proliferation achievement since the 2003 Libya deal. A follow-on process that collapses — leaving Iran with a partially damaged nuclear programme and no lasting constraints — would leave the region in a worse position than the JCPOA’s collapse of 2018 produced.
The war is over. The reckoning has just begun.
