US-Israel war on Iran

Despite United States President Donald Trump’s repeated declarations of victory in the US-Israeli war on Iran, Tehran’s retaliatory strikes on Israel and US military assets in the region have continued, upending global financial and energy markets.

“We’ve had two decades to study defeats of the US military to our immediate east and west. We’ve incorporated lessons accordingly,” Iranian Foreign Minister Seyed Abbas Araghchi wrote in a post on X on March 1, the day after US and Israeli strikes on Tehran killed Iran’s Supreme Leader Ayatollah Ali Khamenei and other senior Iranian officials.

“Bombings in our capital have no impact on our ability to conduct war,” he wrote.

According to analysts, Iran has made use of “asymmetric” warfare tactics while striking the US and Israel. So, are Tehran’s war tactics working?

Here’s what we know:

What is ‘asymmetric’ warfare?

When the balance of capabilities is unequal in a conflict – as it is in relation to weapons in this one – the weaker party can turn to unconventional methods of warfare, John Phillips, a British safety, security and risk adviser and a former military chief instructor, told Al Jazeera.

This is known as “asymmetric” warfare.

This can include the use of guerrilla tactics, terrorism, cyberattacks, use of proxies and other indirect tools, Phillips said, in order “to offset conventional inferiority, avoid the enemy’s strengths, and exploit vulnerabilities in political will, logistics, and legal or ethical constraints”.

“Iran is conventionally weaker than the US and Israel, but relatively strong compared to many neighbours,” he said.

“What makes Iran distinctive is not that it uses these methods at all, but that they sit at the centre of its grand strategy rather than at its margins.”

Why is Iran using asymmetric warfare?

In the ongoing war between Iran and the US-Israel, Washington and Tel Aviv have been using expensive missiles and drones to attack Iran and to intercept missiles Iran has fired back. The Patriot and THAAD defence systems, for example, which launch interceptors to take out incoming drones and missiles, can cost millions of dollars for each missile they fire. This compares with the $20,000-$35,000 cost of each Iranian Shahed drone.

As a result, the US has reportedly spent $2bn a day in its war on Iran and there are fears it could run out of interceptor missiles altogether if the war goes on for more than a few weeks.

It is therefore in Iran’s interests to focus on holding out against strikes and protecting its own weapons supplies while it does so, military experts say.

However, Phillips explained that precision strikes and sabotage by Israel and the US have demonstrated that Iran is not able to fully shield its missile, drone and nuclear‑related assets, while sanctions and domestic pressures have limited its capacity to sustain a very high‑tempo confrontation.

“As a result, Iran’s asymmetric approach is best understood as an effective ‘survival and leverage’ mechanism that produces a chronic, costly ‘shadow war’, rather than a path to decisive regional hegemony or victory,” he said.

Iran began using asymmetric warfare techniques following the 1979 Iranian revolution, which overthrew Shah Mohammad Reza Pahlavi.

“Instead of trying to match high‑end aircraft, precision munitions, or blue‑water fleets, [Iran] has built a ‘forward deterrence’ posture that operates in the grey zone between war and peace,” Phillips said.

“This is backed by large inventories of ballistic and cruise missiles, mass‑produced drones [often handed to proxies], cyber-operations, and a posture of underground, dispersed and hardened facilities that make preemption difficult and preserve some retaliatory capability.”

What asymmetric tactics has Iran been using?

Enemy depletion tactics

Since US-Israeli strikes on Iran began on February 28, Tehran has launched a wave of ballistic missiles targeting Israel and US military bases across the Gulf region.

Using a mix of short and medium-range ballistic missiles, as well as drone swarms through this defence system, Iran aims to deplete Israeli and US interceptor stockpiles.

Economic warfare

Iran has shut down the Strait of Hormuz through which about 20 percent of global oil and gas supplies are shipped. Linking the Gulf to the Gulf of Oman, the strait is the only waterway to the open ocean available to Gulf oil producers.

On Thursday, Iran attacked fuel tankers in Iraqi waters. Instability in and around the Strait of Hormuz drove Brent crude oil prices past $100 a barrel last week, with wild swings ongoing, prompting fears of a global energy crisis.

Iran has also targeted civilian infrastructure like airports and desalination plants which are crucial for water supply in the region, and it has launched drones targeting oil depots.

War on global finance

Meanwhile, on Wednesday this week, Iran’s Islamic Revolutionary Guard Corps (IRGC) threatened to attack “economic centres and banks” with links to United States and Israeli entities in the Gulf region after what it claimed was an attack on an Iranian bank, with the war in its 12th day.

Since then, many banks like Citibank and HSBC in Qatar, have begun shutting, further threatening global financial stability.

Top technology companies such as Google, Microsoft, Palantir, IBM, Nvidia and Oracle, as well as the listed offices and infrastructure for cloud-based services, are also located in several Israeli cities and in some Gulf countries, which Iran has also threatened to attack.

Use of proxies

Iran has aimed to keep the much more powerful US military and its allies off balance through proxies in Iraq, Lebanon and Yemen. Hezbollah in Lebanon, for example, has fired missiles and drones into northern Israel since March 2 as part of Iran’s retaliatory strikes.

“At the core of this [asymmetric] approach is a network of proxies and partners – Hezbollah in Lebanon, Shia militias in Iraq, groups in Syria, Hamas and Palestinian Islamic Jihad in Gaza and the Houthis in Yemen – which receive weapons, training, funding and ideological guidance from Iran,” Phillips said.

These actors allow Tehran to threaten Israeli and US forces, as well as regional shipping lanes, on multiple fronts, “often with a degree of deniability and at a fraction of the cost of deploying its own regular forces”, Phillips noted.

‘Mosaic’ defence system

Iran has organised its defensive structure into multiple regional and semi-independent layers instead of concentrating power in a single command chain that could be paralysed by a decapitation strike. This concept is most closely associated with the formation of the parallel military force, the Islamic Revolutionary Guard Corps (IRGC), particularly under former commander Mohammad Ali Jafari, who led the force from 2007 to 2019.

The doctrine has two central aims: to make Iran’s command system difficult to dismantle by force, and to make the battlefield itself harder to resolve quickly by turning Iran into a layered arena of regular defence, irregular warfare, local mobilisation and long-term attrition.

What damage have these tactics done to the US and Israel?

Iran’s asymmetrical playbook has made the war more expensive for the US. It has been forced to spend money on replacing stockpiles of expensive missiles like Tomahawks and defensive systems such as Patriot and THAAD interceptors.

According to the Center for Strategic and International Studies (CSIS), the first 100 hours alone of Operation Epic Fury – the codename for the US-Israeli assault on Iran – cost the US approximately $3.7bn, mostly unbudgeted. Israel, already reeling from the economic strain of its prolonged wars in Gaza and Lebanon, faces mounting domestic pressure as daily sirens force millions into bunkers.

While the Pentagon has not yet announced an official estimate for the cost of the war, late last week, two congressional sources told US broadcaster MS NOW that the war is costing the United States an estimated $1bn a day.

A day later, Politico reported that US Republicans on Capitol Hill privately fear the Pentagon is spending close to $2bn a day on the war.

Meanwhile, officials from President Donald Trump’s administration estimated during a congressional briefing this week that the first six days of the war on Iran had cost the US at least $11.3bn, a source familiar with the matter told the Reuters news agency.

Reporting from Washington, DC, following the publication of the CSIS analysis last week, Al Jazeera’s Rosiland Jordan said the Pentagon had put together a $50bn supplemental budget request in order to replace Tomahawk and Patriot missiles and THAAD interceptors already used in the first week of the war, along with other equipment that had been damaged or worn out so far.

Are Iran’s tactics working?

To a certain extent, they are.

According to a report by The Soufan Center, the “pattern of Iranian counterattacks suggests a layered operational approach designed to generate pressure on Gulf states, create regional disruption on land, sea, and air, while simultaneously attempting to exhaust US and allied defensive resources”.

“Tehran appears to be fighting a war of endurance: prolong the conflict, expand the economic battlefield, make the costs increasingly prohibitive, ration advanced capabilities, and impose steady human and financial costs on its adversaries. All with the hope that political tolerance erodes faster in Jerusalem and Washington than in Tehran,” the report noted.

This may be working. Questions about the cost of the war are already causing a political headache for the Trump administration in Washington.

Congress’s House Minority Leader Hakeem Jeffries told reporters at a Capitol Hill news conference last week that President Donald Trump is “plunging America into another endless conflict in the Middle East” and “spending billions of dollars to bomb Iran”.

“But they can’t find a dime to make it more affordable for the American people to go see a doctor when they need one,” he said. “Can’t find a dime to make it easier for Americans who are working hard to purchase their first home. And they can’t find a dime to lower the grocery bills of the American people.”

Trump won the presidency in 2024 largely on the back of a promise to handle the rising cost of living and he faces mid-term elections this year. It is likely that the cost of the war will not play well with voters, analysts say.

In Israel, opposition politician Yair Golan has also criticised his government’s economic management of the war.

In a post on X on Sunday, he wrote: “The war with Iran has been planned for months. The fact that the Israeli government has not prepared an orderly economic plan to support citizens during the war period is a disgrace.

“The serving and working public should not be the one footing the bill for the war out of its own pocket while billions of shekels go to the evading and non-working sector,” he said, adding that the opposition will soon replace the government.

Ali Vaez, director of the Iran Project at the International Crisis Group, told Al Jazeera that at a fraction of the cost – and despite a significant technological gap – Iran has demonstrated an ability to hold the global economy at risk, to pressure Washington into “blinking first”.

“A steady stream of inexpensive drones and limited missile strikes can disrupt the thriving economies of Israel and the Gulf, sending shockwaves through energy markets and ultimately translating into higher prices at American gas stations,” he said.

Phillips, the British safety, security and risk adviser, said the strategy has worked in important but limited ways.

“It has helped the Islamic republic survive intense sanctions, clandestine campaigns and periodic strikes while maintaining a credible ability to hit US bases, Israeli territory and Gulf infrastructure, which in turn raises the political and military cost of any attempt at regime-change war,” he said.

“Iran’s reach – stretching from Lebanon and Syria to Iraq and Yemen – allows it to shape crises, quickly raise the stakes of local conflicts, and force adversaries to devote substantial resources to missile defence, counter‑UAV systems, naval protection and regional coalition management,” he noted.

“However, there are clear constraints and growing problems. Key proxies such as Hezbollah and various militias have suffered leadership and infrastructure losses; the network has become more fragmented and sometimes less controllable, increasing the risk of unwanted escalation even as its coherence as an instrument of policy erodes,” he added.

Al Jazeera’s Tohid Asadi shows the aftermath of US-Israeli airstrikes on a residential neighbourhood in Iran, where rescue teams have been searching for survivors among the rubble.

The war in the Middle East is exposing how dependent the world is on a handful of strategic chokepoints.

The Strait of Hormuz – a narrow waterway in the Gulf – is closed.

The longer this goes on, the faster the global energy map could be reshaped.

From Europe to Asia, countries are facing mounting supply risks and the threat of an inflation shock.

If the conflict between the US, Israel and Iran drags on, alternatives will be hard to find.

But, Russia is shaping up to be a major beneficiary, with soaring prices filling Moscow’s coffers despite Western sanctions.

Lawmakers express concerns as Trump officials project $50bn more may be needed for Iran war funding.

Officials from President Donald Trump’s administration have estimated during a congressional briefing this week that the first six days of the war on Iran had cost the United States at least $11.3bn, a source familiar with the matter told the Reuters news agency.

That figure, from a closed-door briefing for senators on Tuesday, did not include the entire cost of the war, but was provided to lawmakers as they have clamoured for more information about the cost.

Several congressional aides have said they expect the White House to soon submit a request to Congress for additional funding for the war. Some officials have said the request could be for $50bn, while others have said that estimate seems low.

The administration has not provided a public assessment of the cost of the conflict or a clear idea of its expected duration. Trump said during a trip to Kentucky on Wednesday that “we won” the war but that the US would stay in the fight to finish the job.

The $11.3bn figure was first reported on Wednesday by The New York Times.

The human cost

The US-Israeli war on Iran has so far killed about 2,000 people, mostly Iranians and Lebanese, as the conflict has spread across the Middle East, with Iranian retaliatory strikes on neighbouring countries hosting US assets, sending energy prices soaring.

The United Nations children’s agency (UNICEF) says the “intensifying conflict” has killed or wounded 1,100 children, creating a “catastrophic” situation for millions of children across the Middle East.

About 800,000 people have already been displaced in Lebanon by relentless Israeli bombardment.

Administration officials also have told lawmakers that $5.6bn of munitions were used during the first two days of strikes.

Members of Congress, who may soon have to approve additional funding for the war, have expressed concern that the conflict will deplete US military stocks at a time when the defence industry was already struggling to keep up with demand.

Democratic lawmakers have demanded public testimony under oath from administration officials about the Republican president’s plans for the war, including how long it might last and what his plans are for Iran once the fighting has stopped.

Trump on Wednesday said the war with Iran may end “soon” because there is “practically nothing left” for the US military to bomb. He did not provide any evidence for that claim.

Israeli journalist and writer, Gideon Levy, says that regime change in Iran is unlikely and the decision to end the war ultimately rests with US President Trump, not Israel.

Iranian explosive-laden boats appear to have attacked two fuel tankers in Iraqi waters, setting them ablaze and killing one crew member, after projectiles struck three vessels in Gulf waters, according to reports.

The ships targeted in late-night ⁠attacks on Wednesday in the Gulf near Iraq were the Marshall Islands-flagged Safesea Vishnu and the Zefyros, which had loaded fuel cargoes in Iraq, two Iraqi port officials told the Reuters news agency.

“We recovered the body of a foreign crew member from the water,” one port security official said, as Iraqi rescue teams continued searching for other missing seafarers. It was not immediately clear which ship that person was linked to.

One Iraqi port security source said Zefyros is flagged ‌in Malta and provided Reuters with a list of crew names.

Al Jazeera’s correspondent in Baghdad, Iraq, Mahmoud Abdelwahed, said the tankers were loaded with crude oil from the Umm Qasr port in southern Iraq in the Basra province, and were attacked soon after their voyage got under way.

“Iraqi officials say this is a flagrant violation of Iraq’s sovereignty given the fact this act, they say, of sabotage has happened in Iraq’s territorial waters,” Abdelwahed said.

Reuters said that reports of the use of explosive-laden unmanned surface vessels, which Ukraine has used with great effect in its war with Russia, come as Iran has blocked oil shipments from transiting the key Strait of Hormuz, through which one-fifth of ⁠the world’s oil transits but has been blocked amid the United States-Israeli war on Iran.

Reuters, citing two unnamed sources, also reported on Wednesday that Iran ‌has deployed about a dozen mines in the strait, while US President Donald Trump said US forces had struck 28 Iranian mine-laying vessels, amid warnings by Trump of severe repercussions should Iran lay mines in the key waterway for global shipping.

Strait of Hormuz sealed

Iran’s Islamic Revolutionary Guard Corps (IRGC) have warned that any ship passing through the Strait of Hormuz will be targeted.

The Thai-flagged Mayuree Naree dry bulk vessel was struck by “two projectiles of unknown origin” while sailing through the strait earlier on Wednesday, causing a fire and damaging the engine room, the ship’s Thai-listed operator Precious Shipping said in a statement.

“Three crew members are ⁠reported missing and believed to be trapped in the engine room,” Precious Shipping said.

“The company is working with the relevant authorities to rescue these three ⁠missing crew members,” it said, adding that the remaining 20 crew members had been safely evacuated and were ashore in Oman.

Images shared by Thai news outlet Khaosod English showed what were reported to be crew members of the ship after their rescue by Oman’s navy.

The IRGC said in a statement carried by the semi-official Tasnim news agency that the ship was “fired upon by Iranian fighters”, suggesting the first direct engagement by the IRGC, who have previously fired missiles or drones.

The Japan-flagged container ship ONE Majesty also sustained minor damage on Wednesday from an unknown projectile 25 nautical miles (about 46 kilometres) northwest ⁠of Ras al-Khaimah in the United Arab Emirates, two maritime security firms said. Its Japanese owner Mitsui OSK Lines and a spokesperson for Ocean Network Express, its charterer, said the vessel was struck while at anchor in the Gulf, and an inspection of the hull revealed minor damage above the waterline.

All crew are safe, they said, adding that the vessel remains fully operational and seaworthy. The owner said the cause of the incident remained unclear and was under investigation.

A third vessel, a bulk ‌carrier, was also hit by an unknown projectile approximately 50 nautical miles (about 93km) northwest of Dubai, maritime security firms said.

The projectile had damaged the hull of the Marshall Islands-flagged Star Gwyneth, maritime risk management company Vanguard said, adding that the vessel’s crew were safe. Owner Star Bulk Carriers said the ship was hit in the hold area while it was anchored. There were no crew injuries and no listing.

The US Navy has refused near-daily requests from the shipping industry ⁠for military escorts through the Strait of Hormuz since the start of the war on Iran, saying the risk of attacks is too high for now, sources familiar with the matter told Reuters.

The Bahraini interior ministry released footage of a massive blaze at a fuel storage facility following an Iranian attack. Bahrain hosts the US Navy’s Fifth Fleet and has been consistently targeted amid the US-Israeli initiated war.

Some supporters of the US-Israeli war on Iran are using the treatment of women in the country as a justification for bombing it. Al Jazeera’s Ava Warriner explains.

Two foreign tankers were seen ablaze in Iraqi territorial waters after a strike near the al-Faw port. Authorities say they evacuated 25 crew members but have confirmed at least one death and are battling to control the flames.

The UN Security Council has passed a resolution put forward by Gulf Cooperation Council members calling on Iran to halt its attacks on Gulf countries. The measure was adopted with 13 votes in favour and two abstentions, while no member states voted against it.

Warning comes as 400 million barrels of oil are being released from global reserves during waterway’s closure.

Iran’s Islamic Revolutionary Guard Corps (IRGC) says it will not allow “a litre of oil” through the Strait of Hormuz as the closure of the key Gulf waterway continues to roil global energy markets during the US-Israeli war on Iran.

A spokesperson for the IRGC’s Khatam al-Anbiya Headquarters said on Wednesday that any vessel linked to the United States and Israel or their allies “will be considered a legitimate target”.

“You will not be able to artificially lower the price of oil. Expect oil at $200 per barrel,” the spokesperson said in a statement. “The price of oil depends on regional security, and you are the main source of insecurity in the region.”

Global oil prices have fluctuated wildly this week during continued US-Israeli attacks against Iran, which has retaliated by firing missiles and drones at targets across the wider Middle East.

The closure of the Strait of Hormuz, through which about one-fifth of the world’s oil supplies transit, and production slowdowns in some Gulf countries have raised concerns of further disruptions.

Concerns around the duration of the war, which began on February 28 and has shown no sign of abating, are also adding to uncertainty, sending oil prices soaring.

On Wednesday, three ships were hit by projectiles in the Strait of Hormuz, maritime security and risk firms said, including a Thai-flagged cargo vessel that came under attack about 11 nautical miles (18km) north of Oman.

Release of oil reserves

World leaders, including members of the Group of Seven (G7) and the European Union, have been mulling what action to take in response to the war’s impact on global economies.

Christian Bueger, a professor of international relations at the University of Copenhagen and an expert in maritime security, said Europe will be facing “a major energy supply crisis” if the Strait of Hormuz is not reopened.

“For the shipping industry right now, it’s impossible to go through the Strait of Hormuz,” Bueger told Al Jazeera. “And if there are not stronger signals in the near future that they can at least try to go through the strait, then we are looking at a major shipping crisis, which can last weeks if not months.”

On Wednesday, the International Energy Agency (IEA) announced that its 32 member countries had unanimously agreed to release 400 million barrels of oil from their emergency reserves to try to lower prices.

“This is a major action aiming to alleviate the immediate impacts of the disruption in markets,” IEA Executive Director Fatih Birol said during an address from the agency’s headquarters in Paris.

“But to be clear, the most important thing for a return to stable flows of oil and gas is the resumption of transit through the Strait of Hormuz,” he added.

The reserve supplies will be made available “over a timeframe that is appropriate” for each member state, the IEA said in a statement without providing details.

German Economy and Energy Minister Katherina Reiche said earlier in the day that the country would comply with the release while Austria also said it would make part of its emergency oil reserve available and extend its national strategic gas reserve.

Meanwhile, Japan’s Ministry of Economy, Trade and Industry said it would release about 80 million barrels from its private and national oil reserves.

Japanese Prime Minister Sanae Takaichi said the country, which gets about 70 percent of its oil imports through the Strait of Hormuz, would begin releasing the reserves on Monday.

Motorists around the globe are already feeling the impact of the United States and Israel’s war on Iran, with fuel prices sharply rising since the war began.

In the US, a gallon of regular petrol that averaged $2.94 in February now costs $3.58, marking a 20 percent increase, according to data from AAA Fuel Prices, a retail fuel price tracker from the American Automobile Association (AAA).

While each US state sets its own petrol prices, several states have surpassed $4 per gallon, with California exceeding $5 per gallon, the highest level it has been in more than two years.

Which countries have the sharpest petrol price increases?

According to data analysed from Global Petrol Prices, a data platform that tracks and publishes retail energy prices across approximately 150 countries, at least 85 countries have reported increases in petrol prices following the initial attacks on Iran by the US and Israel on February 28. Some nations announce price changes only at the end of each month, so higher prices are expected for many others in April.

Vietnam recorded the highest petrol price increase of nearly 50 percent, rising from $0.75 per litre of 95-octane on February 23 to $1.13 on March 9. Laos follows with a 33 percent increase, then Cambodia at 19 percent, Australia at 18 percent, and the US at 17 percent.

The table below shows the countries that have increased petrol prices at the pumps.

Asian countries pay the biggest price

Asia is disproportionately dependent on the Strait of Hormuz for the delivery of its oil and gas, which has been effectively closed since the start of the war. The strait joins the Gulf – also referred to as the Persian Gulf and the Arabian Gulf – to the Gulf of Oman and is the only passage for the region’s oil producers to the open ocean.

Japan and South Korea are among the most vulnerable, importing 95 percent and 70 percent of their oil from the Gulf, respectively.

Both East Asian nations have enacted emergency measures to stabilise their energy markets. On March 8, Japan instructed its oil reserve sites to prepare for a potential release of strategic reserves. The next day, South Korea introduced a maximum price cap on petrol and diesel for the first time in 30 years.

In South Asia, the impact of the war is more severe than in East Asia because countries like Pakistan and Bangladesh have much thinner financial buffers and smaller strategic reserves.

In an attempt to conserve energy, Bangladesh‘s government has ordered all public and private universities to close immediately. In Pakistan, government offices will now operate a four-day workweek, while schools have closed, and a 50 percent work-from-home policy has been enacted to save fuel.

In Europe, the Group of Seven finance ministers convened an emergency meeting to discuss rising prices, with French President Emmanuel Macron raising the possibility of releasing 20-30 percent of emergency strategic reserves to ease the pressure on consumers.

How high oil costs drive up the price of food

Oil prices and food prices move in lockstep, with energy prices affecting every stage of the food supply chain, from the fertilisers used in the fields to the trucks that carry food from field to supermarket shelf.

Rising oil prices also directly affect shipping and the cost of transport.

“The lifeblood of the global economy is transport,” economist David McWilliams told Al Jazeera. “It’s getting stuff from A to B – it’s a logistics problem, a supply chain problem, and ultimately transportation is the energy of the global economy.”

Fears of stagflation – increasing inflation and rising unemployment, which major oil shocks have historically summoned – are rising. Economists point to the crises of 1973, 1978 and 2008 as evidence that every significant spike in oil prices has been followed, in some form, by global recession.

In lower-income countries, where populations spend a far greater share of their income on food and import large quantities of grain and fertiliser, rising oil prices could rapidly translate into food shortages.

What products are made from oil and gas?

Oil and gas are used for far more than just fuel. They are raw materials for thousands of everyday products.

Plastics, including water bottles, food packaging, phone casings and medical syringes, are all derived from crude oil.

Crude oil is also the hidden ingredient in synthetic fabrics such as polyester, nylon and acrylic, which are used to make everything from sportswear to carpets. It also underpins the cosmetics industry, as it is used to make products such as petroleum jelly (Vaseline), lipsticks and concealers.

Household items also rely on oil-based ingredients, with laundry detergents, dishwashing liquids, and paints all derived from petroleum products.

The global food supply is essentially built on natural gas in the form of fertilisers, used to enhance crop yields and ensure that food production can meet demand.

For years, Iran’s leaders believed time was on their side.

After the United States withdrew from the 2015 nuclear agreement, known as the Joint Comprehensive Plan of Action (JCPOA), Tehran effectively adopted what later came to be described as a “strategic patience” approach. Rather than immediately counter-escalating, Iran chose to endure economic pressure while waiting to see whether diplomacy could be revived.

The logic behind the strategy was simple: eventually, Washington would recognise that confrontation with Iran was against its own interests.

Today, that assumption lies shattered.

The collapse of diplomacy and the outbreak of war have forced Iran’s leadership to confront a painful reality: their belief that the US would ultimately act rationally may have been a profound miscalculation.

If Iran survives the current conflict, the lessons Iranian leaders draw from this moment may motivate them to pursue a nuclear deterrent.

The strategy of waiting

After the first Trump administration withdrew from the JCPOA and launched its “maximum pressure” campaign in 2018, Tehran initially avoided major counter-escalation. For nearly a year, it largely remained within the deal’s limits, hoping the other signatories, particularly Europeans, could preserve the agreement and deliver on the promised economic benefits despite US sanctions.

When that failed, Tehran began gradually increasing its nuclear activities by expanding enrichment and reducing compliance step by step while still avoiding a decisive break.

The pace accelerated after Iran’s conservative-dominated parliament passed a law mandating a significant increase in nuclear activities, in the wake of the assassination of top nuclear scientist Mohsen Fakhrizadeh. The shift was reinforced further by the 2021 election of conservative President Ebrahim Raisi.

The ultimate goal was to rebuild negotiating leverage, as Tehran believed that broader geopolitical and regional trends were gradually shifting in its favour. From its perspective, China’s rise, Russia’s growing assertiveness, and widening fractures within the Western alliance suggested that Washington’s ability to isolate Iran indefinitely might weaken over time.

At the same time, Iran pursued a strategy of reducing tensions with its neighbours, seeking improved relations with Gulf states that had previously supported the US “maximum pressure” campaign. By the early 2020s, many Gulf Cooperation Council countries had begun prioritising engagement and de-escalation with Iran, culminating in moves such as the 2023 Saudi-Iran rapprochement brokered by China.

Against this backdrop, even as tensions rose, Tehran continued to pursue diplomacy. Years of negotiations with the Biden administration aimed at restoring the JCPOA ultimately produced no agreement. Subsequent diplomatic efforts under Trump’s second presidency also collapsed.

Underlying this approach was a fundamental assumption: that the US ultimately preferred stability to war. Iranian officials believed Washington would eventually conclude that diplomacy, rather than endless pressure or a major war, was the most realistic and least costly path forward.

The joint US-Israeli assault on Iran has now exposed how deeply flawed that assumption was.

The return of deterrence

While Tehran based its strategy on mistaken beliefs about the rationality of US foreign policy, Washington, too, is misreading the situation.

For years, advocates of the maximum pressure campaign argued that sustained economic and military pressure would eventually fracture Iran internally. Some predicted that war would trigger widespread unrest and even the collapse of the regime.

So far, none of those predictions has materialised.

Despite the enormous strain on Iranian society, there have been no signs of regime disintegration. Instead, Iran’s political base — and in many cases broader segments of society — has rallied in the face of external attack.

Furthermore, Iran spent years reinforcing its deterrence capabilities. This involved expanding and diversifying its ballistic missile, cruise missile and drone programmes and developing multiple delivery systems designed to penetrate sophisticated air defences. Iranian planners also drew lessons from the direct exchanges with Israel in 2024 and the June 2025 war, improving targeting accuracy and coordination across different weapons systems.

The focus shifted towards preparing for a prolonged war of attrition: firing fewer but more precise strikes over time while attempting to degrade enemy radar and air defence systems.

We now see the results of this work. Iran has been able to inflict significant damage on its adversaries. Retaliatory attacks have killed seven Americans and 11 Israelis, placing a growing strain on US and Israeli missile defence systems, as interceptors are steadily depleted.

Iranian missile and drone strikes have hit targets across the region, including high-value military infrastructure such as radar installations. The closure of the Strait of Hormuz has sent global energy markets into turmoil.

Apart from the immense cost of war, the US decision to launch the attack on Iran may have another unintended consequence: a radical shift in Iranian strategy.

For decades, Supreme Leader Ali Khamenei maintained a longstanding religious prohibition on nuclear weapons. His assassination on the first day of the war may now motivate the new civilian and military leadership of the country to rethink its nuclear strategy.

There may now be fewer ideological reservations about pursuing nuclear weapons. The logic is simple: if diplomacy cannot deliver sanctions relief or permanently remove the threat of war, nuclear deterrence may appear to be the only viable alternative.

Iran’s actions in this conflict suggest that many leaders now see patience and diplomacy as strategic mistakes. These include the unprecedented scale of Iranian missile and drone attacks across the region, the targeting of US partners and critical infrastructure, and political decisions at home that signal a harder line, most notably the appointment of Mojtaba Khamenei as supreme leader.

The choice of Khamenei’s son breaks a longstanding taboo in a system founded on the rejection of hereditary rule and reflects a leadership increasingly prepared to abandon previous restraints.

If a more zero-sum logic of deterrence takes hold across the region, replacing dialogue as the organising principle of security, the Middle East may enter a far more dangerous era in which nuclear weapons are viewed as the ultimate form of deterrence and nuclear proliferation can no longer be stopped.

Video shared online shows the destruction caused to buildings and vehicles in Iran’s capital after a reported strike near Mehrabad international airport.

Mohammed bin Abdulaziz al-Khulaifi also says Qatar and Oman cannot act as mediators while under attack.

Qatar’s minister of state for foreign affairs has called for a de-escalation in hostilities across the Middle East and urged Iran and the US to return to the negotiation table for a mediated solution.

Speaking to Al Jazeera in an exclusive interview, Mohammed bin Abdulaziz al-Khulaifi said that Iran’s attacks on its regional neighbours bring “benefit for no one”.

Iran has responded to a nearly two-week-long bombardment campaign from the United States and Israel by firing missiles and drones at its neighbours in the Gulf region and beyond, causing casualties, damaging critical infrastructure and severely disrupting the region’s energy-driven economy.

Al-Khulaifi said Qatar remains “extremely worried” about the wider range of attacks, including against civilian infrastructure.

“It’s unfortunate where we are standing right now,” the minister said.

“We also believe that there is no pathway to a sustainable and long-lasting solution other than returning to the negotiation table,” he told Al Jazeera.

Qatar condemns in the “strongest terms, the unjustified and outrageous attacks on the state of Qatar that directly impact its own sovereignty”, he said.

Doha will continue to take “every possible and legal measure to defend and practise its exercise of self-defence against this aggression”, he added.

Al-Khulaifi said the conflict demands a “global solution” to ensure that the Gulf’s energy supply chain keeps moving through the Strait of Hormuz, where global traffic has been severely disrupted by the conflict.

Ensuring freedom of movement through the waterway is “very critical,” he noted.

It is notable, Al-Khulaifi pointed out, that Iran has targeted countries such as Qatar and Oman, which had previously served as regional mediators and tried to “build bridges between Iran and the West”.

Neither country can play that role as long as the attacks continue, he said.

“We will not be able to fulfil that role under attack, and that’s something the Iranians need to understand.”

Qatari Prime Minister Mohammed bin Abdulrahman Al Thani tried to convey those points during a phone call with Tehran several days ago, the foreign minister said, when he urged Iran to cease attacks on its neighbours.

“The regional countries are not an enemy of Iran, and the Iranians are not understanding that idea,” Al-Khulaifi told Al Jazeera.

Doha also remains in contact with officials in the US and has encouraged US President Donald Trump to cease hostilities, he said.

“Our line of communication is always open with our colleagues in the United States, and we keep encouraging and supporting the pathway of peace and resolving conflicts through peaceful means.

“We really hope that the parties can find that pathway, end military operations, and return to the negotiation table.”

A group of Democrats in the United States Senate is demanding public hearings on the country’s war against Iran after receiving a series of classified briefings from officials in President Donald Trump’s administration.

Lawmakers say the White House has not clearly explained why the US entered the conflict, what its goals are, or how long it may last.

Republicans currently hold a narrow, 53-47 Senate majority, which gives them the power to control what legislation comes to the floor for debate.

Some Democrats have expressed frustration after the latest closed-door briefing. Trump has not ruled out sending US ground ⁠troops into Iran.

“I just came from a two-hour classified briefing on the war,” Senator Chris Murphy from the state of Connecticut said on Tuesday. “It confirmed to me that the strategy is totally incoherent.

“I think this is pretty simple: if the president did what the Constitution requires and came to Congress to seek authorisation for this war, he wouldn’t get it – because the American people would demand that their members of Congress vote no,” he added.

Here is what we know:

What has happened so far?

Since the US and Israel launched attacks on Iran on February 28, senior officials, including Secretary of State Marco Rubio and Defense Secretary Pete Hegseth, have held several closed-door meetings to brief Congress members on the military campaign and its progress.

Because the meetings are classified, lawmakers are restricted in what they can publicly disclose about the information they received.

What are Democrats saying?

Several Democratic senators have said they left the briefings frustrated, arguing that the administration had not provided clear answers about the war’s objectives, timeline or the long-term strategy guiding their approach to the conflict.

Earlier this week, six Democratic senators also called for an investigation into a strike on a girls’ school in Minab, in southern Iran. Reports indicate the attack, which investigators say involved US forces, killed at least 170 people, most of them children.

“There seems to be no endgame,” Democratic Senator Richard Blumenthal said. “The president, almost in a single breath, says it’s almost done, and at the same time, it’s just begun. So this is kind of contradictory.”

Senator Elizabeth Warren from Massachusetts raised concerns about the cost of war.

“The one part that seems clear is that while there is no money for 15 million Americans who lost their health care, there’s a billion dollars a day to spend on bombing Iran,” Warren said on Tuesday.

“The one thing Congress has the power to do is to stop actions like this through the power of the purse,” she added.

Others seem worried that a ground deployment could take place.

“We seem to be on a path toward deploying American troops on the ground in Iran to accomplish any of the potential objectives here,” Blumenthal, of Connecticut, told reporters after Tuesday’s classified briefing.

“The American people deserve to know much more than this administration has told them about the cost of the war, the danger to our sons and daughters in uniform and the potential for ⁠further escalation and widening of this war,” he added.

What are Republicans saying?

Republicans, who have slim majorities in both houses of Congress, have almost unanimously backed Trump’s campaign against Iran, with only a handful expressing doubt about the war.

Some Republican leaders say the strikes are necessary to curb Iran’s military capabilities, missile programme and regional influence.

They have also argued that the operation is limited in scope and designed to weaken Iran’s ability to threaten US forces and allies in the region.

Republican Representative Brian Mast of Florida, chairman of the House Foreign Affairs Committee, last week publicly thanked Trump for taking action against Iran, saying the president is using his constitutional authority to defend the US against the “imminent threat” posed by Tehran.

But some Republican members of Congress have voiced concerns.

Representative Nancy Mace from South Carolina said she did “not want to send South Carolina’s sons and daughters into war with Iran”, in a post on X.

Rand Paul, a Republican senator from Kentucky, accused the Trump administration of changing its narrative and rationale for the war on a daily basis.

“We keep hearing new reasons for war with Iran—none convincing,” he wrote on X. “‘Free the oppressed’ sounds noble, but where does it end? We’ve been told for decades Iran is weeks from a nuke. War should be a last resort, not our first move. A war of choice is not my choice.”

Why does the debate matter?

The dispute has revived a long-running debate in Washington, DC, about the limits of presidential war powers.

Under the US Constitution, Congress has the authority to declare war, but modern presidents have frequently launched military operations without formal congressional approval, often citing national security or emergency threats.

The law allows the president to deploy US forces for up to 60 days without congressional authorisation, followed by a 30-day withdrawal period if Congress does not approve the action.

Some lawmakers and legal experts say the war on Iran highlights the need for stronger congressional oversight of military action.

“In the 1970s, we adopted something called the War Powers Resolution that gives the president limited ability to do this,” said David Schultz, a professor in the political science and legal departments at Hamline University.

“And so, either you could argue that what the president is doing violates the Constitution by… not [being] a formally declared war; or b, it exceeds his authority, either as commander-in-chief or under the War Powers Act,” he added.

“And therefore, you could argue that domestically, his actions are illegal and unconstitutional,” Schutlz said.

The Trump administration has argued that the February 28 strikes were justified as a response to an “imminent threat”, a rationale often used by presidents to justify military action without prior congressional approval.

However, US intelligence agencies had themselves said before the start of the war that they had no evidence of an imminent Iranian threat to the US or its facilities across the Middle East.

Washington, DC – Several Democrats in the United States have emerged from a classified briefing about the war on Iran, saying they still have little clarity about President Donald Trump’s justifications and end goals, even 11 days into the conflict.

“I emerge from this briefing as dissatisfied and angry, frankly, as I have from any past briefing in my 15 years,” said Senator Richard Blumenthal, following Tuesday’s briefing to the Senate Armed Services Committee.

Their statements marked the latest wave of condemnation from congressional Democrats, who have a slim minority in the Senate and the US House of Representatives.

Party members in both chambers had recently voted in near unison on resolutions seeking to halt the war, which the US and Israel launched on February 28.

But their efforts to pass a “war powers resolution” to rein in Trump failed amid widespread Republican opposition.

More recently, Democrats have pledged to delay proceedings in the Senate unless top officials from the Department of State and the Pentagon testify under oath about the war.

Following Tuesday’s briefing, Democrats like Blumenthal argued that the Trump administration owes the US public more clarity about the war.

Blumenthal added that the meeting piqued concerns that US forces may be deployed to either Iraq or Iran.

“I am left with more questions than answers, especially about the cost of the war,” he said.

“I am most concerned about the threat to American lives of potentially deploying our sons and daughters on the ground in Iraq. We seem to be on a path towards deploying American troops on the ground in Iran to accomplish any of the potential objectives.”

Senator Elizabeth Warren, meanwhile, said that the Trump administration “cannot explain the reasons that we entered this war, the goals we’re trying to accomplish and the methods for doing that”.

She also pointed to the high cost of the military operations against Iran, which some have estimated to exceed $5.6bn in the first two days alone.

Warren pointed out that Republicans cut healthcare subsidies last year in an effort to reduce federal spending, but appear to have no problem approving military expenses.

“While there is no money for 15 million Americans who lost their healthcare”, she noted, “there’s a billion dollars a day to spend on bombing Iran”.

While approached by reporters, Senator Jacky Rosen indicated she was limited in her ability to comment on classified briefings. Still, she offered brief remarks to voice her frustration.

“I can tell you what I heard is not just concerning. It is disturbing,” she said. “And I’m not sure what the end game is or what their plans are. They certainly have not made their case.”

‘On our timeline and at our choosing’

The latest round of criticism came shortly after US Secretary of Defense Pete Hegseth pledged to conduct the “most intense day” of strikes since the war began.

As of Tuesday, the war had killed at least 1,255 people in Iran, 394 people in Lebanon, 13 in Israel, six in Iraq and 14 across the Gulf.

Trump has repeatedly said the war would not be prolonged, but his officials have offered shifting timelines. Hegseth, for instance, said the fighting would not stop “until the enemy is totally and decisively defeated”.

“We do so on our timeline and at our choosing,” he said.

The Trump administration has also offered an array of justifications for launching the war, which came amid indirect talks with Iran on the future of its nuclear programme.

Trump has blamed Iran’s nuclear ambitions for the conflict, though Tehran has denied seeking a nuclear weapon, and his administration has also said the war was necessary to end Iran’s ballistic missile programme.

Experts have said that available evidence does not support the Trump administration’s claims that either posed an immediate threat to the US.

US Secretary of State Marco Rubio told reporters last week that the US attacked because its close ally Israel had planned to attack Iran, which would have led to retaliation against US assets.

Rubio and Trump subsequently backed away from the circular rationale, with Trump claiming last week that Iran was the one planning to strike first.

Another rationale the Trump administration offered is that the totality of Iran’s actions since the 1979 Islamic revolution represented a threat to the US, thereby necessitating an attack.

Trump and his top officials have not provided evidence for any of their claims.

Calls for hearings, investigation

Democrats have been largely sidelined since the war began. Only a handful of Republicans have joined the left-leaning party in its efforts to rein in Trump through legislative means.

Under the US Constitution, only Congress can declare war. But presidents can still use the military to respond to imminent threats in instances of self-defence.

Still, there are limits to how long such operations can proceed. Under the 1973 War Powers Resolution, presidents must withdraw forces within 60 to 90 days of an unauthorised military campaign, or else seek congressional approval.

Trump, however, has denied he needs congressional backing for the military campaigns he has conducted since returning to office.

The latest attacks in Iran have sparked widespread public opposition, with polls suggesting a majority of US citizens oppose the war effort.

Earlier this week, six Democratic senators called for an investigation into a strike on a girls’ school in Minab, in southern Iran. Several investigations have indicated that the US was responsible for the attack, which killed at least 170 people, mostly children.

Last week, nearly 30 members of Congress called for an investigation into reports that US military leaders had used biblical motivations to justify the war to subordinates.

Some reportedly invoked “religious prophecy and apocalyptic theology” in statements to other enlisted personnel.

On Monday, Senator Cory Booker said Democrats had “collectively agreed” to use an array of procedural mechanisms in the chamber to block legislative business until Trump officials agree to testify under oath.

“Each individual senator has a tremendous amount of power to disrupt the normal functioning of the Senate, as well as certain privileges that we can exercise,” Booker said.

“And what we have agreed right now is that we’re not going to let the Senate continue business as usual, which seems to be ignoring the urgent issues the American people are dealing with.”

A Maronite Catholic priest has been killed by Israeli tank fire after it targeted a home in southern Lebanon. Father Pierre al-Rahi was reportedly killed when an Israeli tank fired on the home of a local couple a second time after several people had rushed there to try to help.

Rescue workers carefully extracted an unexploded missile from a house in Kuhdasht City, following US-Israeli airstrikes on western Iran.

Iran has significant oil and gas reserves, and is a key supplier to China.

A member of US President Donald Trump’s inner circle has said control of those reserves is a key United States aim amid the country’s war against Iran.

So, how valuable are Iran’s natural resources? And could they be a factor in US thinking?

International Energy Agency chief says talks aim to assess conditions as US-Israel war on Iran fuels global uncertainty.

The International Energy Agency (IEA) is set to hold an emergency meeting to assess the situation in the Middle East as the US-Israeli war on Iran continues to roil global energy markets.

Fatih Birol, the agency’s executive director, said representatives of IEA member states would meet on Tuesday to assess “the current security of supply and market conditions” amid the conflict.

“I have convened an extraordinary meeting of IEA member governments, which will take place later today to assess the current security of supply and market conditions to inform a subsequent decision on whether to make emergency stocks of IEA countries available to the market,” Birol said.

This week, oil prices hit their highest levels since mid‑2022 amid concerns of prolonged shipping disruptions linked to the war and reduced output from some key producers in countries that have been targeted by retaliatory Iranian strikes.

While the market reversed late in the day on Monday, with benchmarks falling below $90 a barrel, uncertainty persists around how long the United States-Israel war will drag on.

The Strait of Hormuz, a critical Gulf waterway through which about one-fifth of the world’s oil supplies passes, has effectively been shut down as a result of the war.

“If this drags on, it is not just going to be energy prices” that are affected, Al Jazeera’s Osama Bin Javaid explained. “It is going to have an impact on global economies.”

Bin Javaid noted that the extraordinary IEA meeting comes after Group of Seven (G7) countries met to discuss possible actions to help stabilise global energy markets.

European governments have been on edge about the prospect of a repeat of the energy crisis they faced in 2022, when prices surged to record peaks after Russia’s full-scale invasion of Ukraine.

“The IEA will ⁠be presenting an ⁠in-depth analysis of the pros and ⁠cons of releasing stocks ⁠now,” the European Union’s Energy Commissioner ‌Dan Jorgensen said before the agency’s meeting.

Earlier on Tuesday, G7 energy ministers stopped short of deciding on the release of strategic oil reserves in a call, instead asking the IEA to assess the situation before acting.

“Everyone is willing to take measures to stabilise the market, including the United States,” French Finance Minister Roland Lescure told reporters after the latest talks.

“We have asked the IEA to elaborate scenarios for a potential oil stock release; we need to be ready to act at any moment,” he added.

EU leaders also will discuss competitiveness, including energy prices, on a call later in the day with German Chancellor Friedrich Merz, Italian Prime Minister Giorgia Meloni, Belgian Prime Minister Bart De Wever, and others.
