‘Sami’: ‘Caesar’ Approached Me with Photos of Torture Victims, We Teamed up Against the Dangers

For ten years, the world was eager to uncover the real identity of two men: “Sami” and “Caesar”, who had smuggled photos of victims of torture in the jails of Syria’s ousted President Bashar al-Assad. Their documentation of the torture led the United States to issue the Caesar Act and for trials against Syrian regime members to be held in Europe.

After Assad’s downfall on December 8, Sami chose to reveal his identity – Osama Othman – to Asharq Al-Awsat. Asharq Al-Awsat sat down with him in Paris to recount how Caesar and Sami were born and their journey from the Damascus countryside to world courts in pursuit of justice.

*How did you feel when you learned that Assad had fled Syria?

The truth is we were denied the joy of seeing Assad personally declare that he was leaving power. He never announced his resignation or that he was leaving the country. He simply got on a plane and left Syria. His ouster was not confirmed by a decisive moment, but we had to wait several days for confirmation that he was indeed no longer in Syria and that Syria was now “free Syria” not “Assad’s Syria.” So, our joy took place over stages and an extended period of days that were tinged with hope, fear and anticipation.

*What was your partner Caesar’s reaction to the news?

I haven’t been able to contact Caesar because we were so frantic to confirm that Assad had indeed been toppled and because we were waiting to see what happens next. The truth is that the rapid unfolding of developments and my concerns prevented me from contacting Caesar. This is the moment that we have been waiting for and it has finally been realized. I will use your platform to say to him: “We made it, Caesar.” We achieved what we had sought out to accomplish. We have toppled Assad. “Sami” and Caesar” didn’t do it, but it is the blood of the martyrs in the jails and outside of them. It is the efforts of all Syrians who paid so dearly in blood to reach this moment. We are free. Syria is free.

*So you feel that your work over those long years has not gone to waste?

I believe that the Syrian people have paid a greater price than what a criminal like Assad deserved. He hadn’t remained in his position for all those years due to his intelligence, strength or love of his people. We all know that he remained in power through his regime’s oppressive security apparatus, his allies and all members of his criminal militias, which he brought to Syria to slaughter the people and rob the country.

*Are Assad’s allies partners in the torture?

Assad’s partners are partners in Syria’s destruction. In my position in a rights organization with scores of files on detainees killed under torture, I cannot pin blame on this side or that without evidence. But logically, of course, they were partners in killing everyone who was killed in Syria. They are responsible for every drop of blood spilled. Assad’s allies are partners in his. Everyone who raised their hand at the United Nations Security Council to veto a resolution that liberates the Syrians from Assad’s rule and oppressive regime are complicit as well.

The First Photo

*When did you get the idea to gather the evidence of torture in Syrian jails?

It was during the early days of the revolution, perhaps May 2011. I agreed with Caesar to gather photos that he had obtained and which he had told me at the time showed evidence of extreme torture. Before the revolution, the department concerned with gathering legal evidence received photos of accidents involving members of state and security institutions and the army. The photos were taken regularly and routinely.

When the revolution erupted, photos emerged of people who had come under extreme torture and it was evident that they had not died under normal circumstances or in an accident. At this point Caesar did not want to be involved in even capturing these atrocities. He wanted to distance himself completely from this criminal machine, either by defecting, which would have exposed him or his family to extreme danger or by somehow retiring or resigning from the army.

During this time, my memory of the people who had gone missing in the 1982 Hama massacre was still raw. There are thousands of cases of missing people whose death or detention the state has never acknowledged. Under the law, they are deemed missing, which created a lot of legal problems for families. This was a major problem that had persisted for decades. So, I thought about how gathering evidence would provide our Syrian people proof of what happened to their loved ones, who had been detained during protests, on the streets or during raids.

Despite how horrific the situation was, it would at least provide clear legal evidence and offer the families some form of relief. Relief as in they would no longer live in agony of not knowing whether their loved ones are alive or not.

We decided to gather the data. Since the Egyptian and Tunisian revolts were only a few months in at the time, we believed that the Syrian revolution would perhaps end in a few months as well and we would be able to reveal these documents to our people in Syria. But the months stretched on and the regime grew more brutal and scores of Syrians were killed. We started to routinely collect the documents, not thinking about what we would do with them next. We lived in fear of the regime attacks and its random raids.

*How did you respond when Caesar showed you the first photo? You had to make a choice, either forget about it or forge ahead. What did you feel in that moment?

You can expect anything from the Syrian regime. We were mentally prepared from the start to confront this criminal regime. The arrests and deaths under torture were nothing new to the regime and to us. What was new was the rate of the killing, which reached dozens daily. Caesar would take photos of a large number of corpses every day. The regime had for decades committed these crimes against the Syrian people, but the difference was that today, we had the technology to collect evidence.

*What did you say to Caesar when you first saw the photos?

At first, I was worried about Caesar because he could at any moment become a victim like those in his photos. I told him that we must collect these photos. Caesar’s job at the military allowed him to collect a lot of data that would help us. We didn’t believe at the time that the issue would develop into a global case to criminally pursue the regime.

*How did Caesar feel about this?

Caesar had two choices: either quit his job, which would expose him and his relatives to danger, or find a legal way out of his work. However, he believed that quitting wouldn’t do us or our people justice. Obviously, I didn’t pressure Caesar into continuing his work. We made the decision together out of our conviction. We shared the danger, concerns and work.

*Did you think that your actions could cost you your life at any moment?

The Assad regime was a threat and danger to every human being in Syria, whether they had done anything wrong or not. We were under constant danger, even before the revolution erupted. It is the revolt that helped speed up the process of collecting evidence and exposing the regime’s crimes.

What we did was archive the data, which defintely came with its risks. But, amid the revolt, everyone was paying in blood for freedom, so I never thought that what I am doing was more dangerous than what everyone else was going through. On the contrary, I thought I was playing my own role in this uprising.

Team Grows

*So at the beginning it was just you and Caesar?

In the first months, yes. We kept our work secret from our families. Afterwards, we had to build a team around us to protect me and Caesar and provide assistance that would prevent the data, should one or both of us get killed, from being lost. The team began to expand after two or three months.

*How did you maintain secrecy?

Secrecy was not absolute. I can’t claim to have been surrounded by complete secrecy at the beginning. Before we left the country, only six people, including my brother and Caesar, knew about what we were doing. My wife, of course, knew. In the end, it was seven people.

Missing Eyes

*Where was the first photo taken from?

The photos came from the legal evidence department at the military police branch, meaning the victims in the photos were killed under torture at the security branches across Damascus. There were no photos that indicated the victims were from Seydnaya prison.

*What was the most brutal branch? Did torture differ from one branch to another?

When I started sorting the photos according to which branch they came from, I realized that around 50 percent of the victims came from “Branch 215.” At another branch, 227, I noticed that the majority of the victims had missing eyes. I can’t say that the eyes were removed or became decomposed after death. Insects were eating the eyes in their sockets. This was evident in a large number of photos. Perhaps the decomposition of the body made it seem that eyes were missing or maybe the insects were what ate them.

*Where the victims shot dead or killed by sharp objects?

I leave this for the experts. I may have my own opinion, but since this is a legal file, I won’t say it. German authorities have a full copy of the file and they are examining the data. When I say that the data incriminates Assad, my statements are worthless because I don't have the legal expertise. So, I sought to keep the files away from the media and political debates and entrusted them to German and French authorities. I gave them my testimony so that if anything happens to Sami and Caesar, the information will not be lost.

One Woman

*Were there woman and children among the victims?

We found one woman only. As for the children, we found many under the age of 18. Not just that. We also found patients. It was evident that they were taken out of hospitals or were killed while they were receiving treatment. I cannot be conclusive, but you can see medical equipment, such as tubes in arms, catheters, serum bags, and others, still attached to the body. This was all evidence that they were receiving some form of treatment.

*Were there any labels on the victims after they were killed? How did they give a cause of death?

They would simply state “death of detainee numbered so and so”. That’s all.

*So no cause of death is given?

I will leave this to Caesar to explain himself when he chooses to reveal himself. This is at the heart of his work at the military departments.

*How many photos have been obtained?

There could be up to six photos taken of a single victim, based on their injuries or physical traits. So we have some 27,000 photos of some 7,000 victims.

Leaving Syria

*When did you stop collecting evidence?

By the end of 2013, the situation had grown too dangerous for the people involved. We could have stayed and collected more, but weighing the danger, we believed it was best to get out of Syria before being busted and losing all the work we accomplished and even our families.

I was not wanted by the regime, so I was able to normally leave Syria to Lebanon in the end of 2013. My family and Caesar left Syria soon after and we ended our work of documenting the victims. We don’t have anything from after September 2013. I spent less than two weeks in Beirut. I managed to get our families and Caesar out of Syria. We eventually settled for a while in Qatar.

Caesar never accompanied me when I left. It was just me and another person. Caesar was still at his job in Syria when I left. He never went to Beirut. I will leave it to him to answer how he left Syria.

*What happened in Qatar?

I was in Doha with Caesar and others. We verified again that this man was indeed working for the regime’s military institution and that these photos were genuine and not fakes. This was before I handed the file to the German authorities. This was the beginning of “Sami” and “Caesar”.

Caesar is the “king witness” as they say in Arabic. The term seemed a bit long. One of the gatherers suggested “Caesar” as in king, and so it was. The gatherers said I also needed a name. I chose “Sami” after a dear close friend, who I haven’t seen in 15 years. Sami is an easy name in different languages.

After Doha, I headed to Türkiye and then Europe.

*Did you receive any support from countries or organizations?

We never received any such support. At that time, we were working with a group of Syrian dissidents and we never came in contact with our hosts in Qatar or elsewhere. We are simply people who are not part of any organization.

When we arrived in Europe, we sensed the burden we were carrying. Soon after, the world started to become less interested in Syria and the regime started to reclaim territory after Russia’s intervention. At that moment, I asked myself: why did I take on such dangers? Why did I expose my relatives to them? What was the point? Was the point heading to Europe where I would become a refugee? This is not why I did all of this and this is not what I want for myself and my children. I sensed that my mission and goals were slipping away from me, so I decided to take action.

I contacted French authorities and informed them that I wanted them to have a copy of the file. I said I wanted to testify before the war crimes court and so it was. But it turned out that France could do nothing if the criminal or victim weren’t French or residing on its territories. Germany did so and so we took our case to it.

Our work was based on consolidating a main principle that the regime was criminal and had committed human rights violations and genocide. We were also motivated by preventing the regime from being allowed to polish its images in any way, shape or form, regardless of the developments in Syria. We threw a wrench in efforts to normalize ties with the regime. So, for years, the “Caesar file” was the main obstacle for the regime to end its international isolation.

Caesar Act

*Whose idea was it to go to the United States?

We never had plans to go to the US, but some Syrian organizations working there pressured us into presenting the case to the American administration. I was persuaded that Barack Obama’s administration was not interested in even opening the file due to an incident when I was in Jordan. At the time, some of the earliest photos of the file were sent to the State Department through a defected Syrian lawmaker. The State Department never showed any form of interest in the issue.

Around a year later, the Syrian groups in the US pressured us to approach Washington. They knew how things worked in the administration and how to use this file to make a difference, even if the man in the White House didn’t want to. It was a long battle we waged with our Syrian brothers in the US that was crowned with the issuing of the “Caesar Syria Civilian Protection Act”, or “Caesar Act”.

*Do you believe the Caesar Act helped curb the work of the regime?

We may have to examine closely what impact the Act had on the regime, but it certainly made it difficult for it to rebuild its military machine. It was still able to support its forces and Shabiha (thugs), even the militias it brought in from other countries, to commit more killing and exercise more oppression in Syria.

In the end, this is an American law that meets the interests of the Syrian people in several aspects. I don’t want to say that the Caesar Act was the sole crowning achievement of the Caesar file. Several great efforts were exerted by Syrian organizations in the US and the file was named in honor of this man.

Macron Leaves Future Open as Political Curtain Nears

Macron Leaves Future Open as Political Curtain Nears

With just one year left in his second five-year term, French President Emmanuel Macron has said he will quit politics in 2027 -- leaving observers and supporters guessing about his next moves.

"I wasn't in politics before and I'm not going to be after," Macron said Thursday during a visit to a high school in Cyprus.

He added that at this late stage in office, the "hardest thing" was to strike a balance between defending his record and acknowledging what "didn't work out".

France's political and media world is already abuzz as the race for 2027 has "already begun", said Philippe Moreau-Chevrolet, a communications expert at Sciences Po university.

For now, would-be candidates are playing up their softer sides, with far-right National Rally (RN) party chief Jordan Bardella showing off a romance with Princess Maria Carolina of Bourbon-Two Sicilies in glossy magazine Paris Match.

And Gabriel Attal, one of Macron's string of former prime ministers, has offered personal revelations in a book as he shores up his bid to lead the centrist camp into the 2027 vote.

"Now is a good time for the president-- who in any case won't be in charge of much anymore -- to announce and lay the groundwork for his departure," Moreau-Chevrolet said.

"He needs to tell an alternative story while leaving what's next up to speculation."

- Rear-view mirror -

Macron has sought in recent weeks to spruce up public perceptions of his legacy -- even as would-be successors in his own ranks try to distance themselves from a historically unpopular leader.

The 48-year-old may be hoping to mimic the trajectory of Jacques Chirac, president in the late 1990s and 2000s.

Once out of the cut and thrust of daily politics and with his various scandals fading, conservative Chirac's public image recovered and many now look back on his era with nostalgia.

"At some point there'll be a change in perspective, because he won't be a political personality any longer," a person close to Macron said.

"There'll be a re-emergence of some of the key elements and consistency" in his policy, the person added, such as his push for "industrial and European independence in the face of crises."

Macron remains highly visible outside France, standing up to US President Donald Trump over his threats to annex Greenland and criticizing the war against Iran.

His long-vaunted White House relationship has cooled in recent months as Trump becomes a liability even for his supposed political allies in Europe's far right.

"I didn't speak to him in the last few hours because I didn't see a need for it," Macron said dismissively of Trump Monday during a visit to Poland.

The president's "true role has been on the international stage," said Moreau-Chevrolet.

In January, Macron energized the World Economic Forum in Davos with a "defense of European democracies and Gaullist position" of technological and military emancipation from the United States.

Images raced around the internet of the French leader wearing aviator-style sunglasses to protect a broken blood vessel in his eye, as he called for Europe to stiffen its spine.

- #Macron2032? -

Macron's stated intent to leave active politics "doesn't mean that he'll be out of the picture altogether," Moreau-Chevrolet said.

The person close to Macron said that "he was talking about politics in the party-political sense".

Some observers suggest he could seek a post heading an intergovernmental body such as the International Monetary Fund (IMF) or European Commission.

One centrist leader predicted that "he'll start up an outfit of his own after 2027. And there will be people calling for #Macron2032," the next presidential election when he could stand again.

In the meantime, "he's not taking leave of the questions he's passionate about, reindustrialization of France, AI, the defense industry, international affairs. He leaves the rest to the prime minister and doesn't bother about it," one sitting minister said.

As the 2027 campaign progresses, Macron will likely leave the battle up to the centrist candidate to succeed him -- with the subtext that "I have a legacy and you must stand up for it," the minister added.


Iranians Have Long Sought Work and Relative Stability in Türkiye. The War Could Force Some to Return

Iranians Have Long Sought Work and Relative Stability in Türkiye. The War Could Force Some to Return

Sadri Haghshenas spends her days selling borek — a layered, savory pastry — at a shop in Istanbul, but her mind is on her daughter in Tehran.

The family had to send her home to Iran after they ran into difficulties renewing her visa, despite fears that a shaky ceasefire could soon collapse.

For years, short-term residency permits have allowed tens of thousands of Iranians to pursue economic opportunities and enjoy relative stability in neighboring Türkiye. But it's a precarious situation, and the war has raised the stakes.

“I swear, I cry every day,” Haghshenas said, raising her hands from behind the counter of the pastry shop. “There is no life in my country, there is no life here, what shall I do?”

Haghshenas and her husband moved to Türkiye five years ago with their then-teenage daughters and have been living on tourist visas renewable every six months to two years.

They could not afford a lawyer this year, because her husband is out of work due to health problems. As a result, they missed the deadline to apply for a new visa for their 20-year-old daughter, Asal, who is still in her final year of high school.

Asal was detained at a checkpoint earlier this month and spent a night at an immigration facility. Her mother found a friend to take her back to Tehran rather than face deportation proceedings that could complicate her ability to return to Türkiye. They hope she can come back on a student visa.

Haghshenas has been unable to talk to her daughter since she left because of a monthslong internet blackout in Iran.

Türkiye has not seen an influx of refugees, as most Iranians have sought safety within their country. Many who have crossed the land border were transiting to other countries where they have citizenship or residency.

Nearly 100,000 Iranians lived in Türkiye in 2025, according to the Turkish Statistical Institute. Around 89,000 have entered Türkiye since the start of the war, while around 72,000 have departed, according to the United Nations' refugee agency.

Some Iranians have used short-term visa-free stays to wait out the war, but there are few options for those who want to stay longer.

Sedat Albayrak, of the Istanbul Bar Association’s Refugee and Migrant Rights Center, said that getting international protection status can be difficult, and the system encourages Iranians to apply for short-term permits instead.

“There are people who have lived on them for over 10 years," The Associated Press quoted him as saying.

If the war continues, more may have to return Nadr Rahim came to Türkiye for his children’s education 11 years ago. Now, the war may force him to go home.

Because of the difficulty of getting a permit to start a business or work legally in Türkiye, he lived off the profits of his motorcycle salesroom in Iran. But there have been no sales since the war started, and international sanctions — and the internet outage — make it extremely difficult to transfer funds.

His family only has enough money to stay in Türkiye a few more months. His children grew up in Türkiye and don't read Farsi or speak it fluently. He worries about how they would adapt to living in Iran, but said “if the war continues, we will have no choice but to return.”

In the meantime, he spends most of his days scrolling on his phone, waiting for news from his parents in Tehran or discussing the war over waterpipes with Iranian friends.

A 42-year-old Iranian woman came to Türkiye eight months ago, hoping to make money to support her family. She and her daughter registered as university students to get study visas.

She attends classes in the morning to keep her legal status before rushing to service jobs, sometimes working until 3 a.m.

They share a room with six other people at a women's boarding house, she said, speaking on condition of anonymity out of fear for her security should she return to Iran.

“I truly love Iran. If necessary, I would even go and defend it in war,” she says. But she sees no future there, while in Türkiye, she’s barely scraping by and only able to send small amounts of money to her parents.

“I have a bad life in Türkiye, and my parents have a bad life in Iran,” she said. “I came to Türkiye with so much hope, to support my parents and build a future. But now I feel hopeless.”

A 33-year-old freelance architect from Tehran traveled to Türkiye during Iran's violent crackdown on mass protests in January. She had planned to return after the situation calmed down, but then the United States and Israel went to war with Iran at the end of February.

“I started to believe that it’s a very bad situation, worse than I expected,” she said, speaking on condition of anonymity for fear of persecution if she returns to Iran.

She has been unable to work for her usual clients back in Iran because of the internet blackout. With the end of her 90-day visa-free window approaching, she can't afford to apply for a longer stay in Türkiye.

Instead, she has decided to go to Malaysia, where she will get free accommodation in return for building shelters during a month of visa-free stay.

She has no plan for what comes next.

Shipping traffic through the Strait of Hormuz remained mostly at a standstill on Monday, with just three vessels crossing the vital waterway, according to Kpler, a maritime data firm.

On Sunday, a US Navy destroyer attacked and seized an Iranian-flagged cargo ship that US President Donald Trump said had tried to evade the US blockade on ships traveling to and from Iranian ports.

In a separate incident, the United Kingdom Maritime Trade Operations center, which is administered by Britain’s Royal Navy, said that two vessels had been hit while trying to cross the Strait of Hormuz, according to a notice published on Saturday.

In one instance, gun ships operated by Iran’s Revolutionary Guards Corps fired at a tanker without radio warning, the British organization said. In the second incident, a container ship was hit by “an unknown projectile” that damaged some of the containers.

On Tuesday, the US military said it had seized an Iran-linked tanker in international waters, in what appears to be the latest move to enforce a blockade as the ceasefire deadline looms.

The US military said it had boarded the tanker Tifani “without incident.”

The ship, capable of carrying 2 million barrels of crude, last reported its position on Tuesday morning near Sri Lanka in the Indian Ocean, according to MarineTraffic tracking data. It was close to fully loaded and had signaled Singapore as its destination.

A two-week ceasefire between the US and Iran is set to expire early Wednesday.

Latest developments

The US Navy has turned back 27 ships trying to enter or exit Iranian ports since an American blockade outside the contested Strait of Hormuz began about a week ago, the military’s Central Command said on Monday.

On Sunday, a Navy destroyer disabled and seized the Touska, an Iranian cargo ship, in the Gulf of Oman after it tried to evade the blockade. It was the first time a vessel was reported to have tried to evade the US-imposed blockade on any ship entering or exiting Iranian ports since it took effect last week.

The guided-missile destroyer Spruance, one of more than a dozen Navy warships enforcing the US blockade, ordered the vessel’s crew to evacuate its engine room.

The Spruance then fired several rounds from its Mk-45 gun into the ship’s propulsion system as it steamed toward the port of Bandar Abbas in Iran, Central Command said in a statement that included a video of the firing.

American officials will determine what to do with the disabled vessel once the search is completed, a US military official said on Monday, speaking on the condition of anonymity to discuss operational matters, according to the New York Times. One option would be to tow the stricken ship to Oman, independent specialists said. An alternative would be to let the Touska steam to an Iranian port, if it can.

A spokesman for Iran’s military reiterated a threat on Monday to “take the necessary action against the US military” in response to the ship’s seizure, Iran’s state broadcaster reported.

How is the US imposing the blockade?

According to CENTCOM, more than 10,000 US personnel, including sailors, marines, and airmen, are participating in the operation, supported by over a dozen warships and dozens of aircraft. The effort spans key waterways surrounding Iran, including the Arabian Gulf and the Gulf of Oman.

The US blockade on Iranian ports does not have a defined geographic boundary, and the United States can interdict vessels almost anywhere in international waters until they arrive at their final port.

Analysts say modern technology allows blockade enforcement at great distances.

Can ships evade the blockade?

Maritime intelligence experts say that more ships in and around the Strait of Hormuz seem to be adopting “spoofing” tactics to avoid detection.

Under international maritime law, most large commercial vessels travel with a transponder that automatically transmits the ship’s name, location, route and other identifying information. That includes a nine-digit number with a country code, which serves as a digital fingerprint for a ship.

The tactics were used by Russian “shadow fleet” vessels evading sanctions related to the invasion of Ukraine in 2022.

When a ship is engaged in spoofing, its captain can type in a false origin or destination or can pretend to be piloting another ship altogether. Vessels can also temporarily turn off their transponders, seeming to disappear in one place and reappear in another.

The strait is “a contested information environment,” said Erik Bethel, a partner at Mare Liberum, a maritime technology venture capital fund.

Still, whatever ruses they employ, vessels going to and from Iran may get only so far. It is difficult to pass between the open ocean and a waterway as narrow as the Strait of Hormuz without being detected.

“My expectation is that the US Navy can sit out in the Gulf of Oman,” said Ami Daniel, the chief executive of Windward, a maritime intelligence data provider. “I don’t think there’s a way to breach the blockade.”

What are the US and Iranian strategies?

The US blockade sets up a significant test in the Iran war: Which side can endure more economic pain?

Instead of directing missiles and bombs, Trump is trying to choke off Iran’s oil exports, which make up just about all of the government’s revenue.

Some experts questioned whether the US blockade would work.

“Iran is already hurting, and they have shown that they are willing to take more than a couple of hits,” said Ahmet Kasim Han, a professor of international relations at TED University in Ankara, Türkiye.

Iran’s strategy appears to be using its leverage over global energy markets, where Tehran has discovered new powers that can cause pain in the US economy through spikes in the price of gasoline and other staples.

Why is the strait so important?

The Strait of Hormuz is a strategic waterway connecting the Gulf to the Gulf of Oman and the Indian Ocean. It is the only sea route for moving oil, natural gas and other cargo out of the Gulf. Iran’s coastline runs along the entire route.

At the strait’s narrowest and most vulnerable point — between Iran to the north and the Musandam Peninsula of Oman to the south — the navigable channel is about two miles wide each for inbound and outbound traffic, according to the International Energy Agency.

The legal status of the strait is complex. It lies within the territorial waters of Iran and Oman, but under international law it is treated as an international waterway where ships are generally guaranteed passage.

Iran has signed but not ratified that framework and has disputed the extent of those rights.

Before the war, about 20% of global oil and liquid natural gas passed through the strait. Most of the fossil fuels are bound for Asia, especially China, India, Japan and South Korea.

Other large vessels also use the strait, including car carriers and container ships.

Crucial industrial goods traveling through Hormuz include helium from Qatar, fertilizer from Oman and Saudi Arabia, and plastic feedstocks from Saudi Arabia and Emirati petrochemical plants.

How does Iran control the strait?

Iran’s military can threaten shipping traffic throughout the Strait of Hormuz, even though much of its navy has been destroyed by US and Israeli strikes.

The United States and Israel launched their war against Iran on the argument that if Iran one day got a nuclear weapon, it would have the ultimate deterrent against future attacks.

It turns out that Iran already has a deterrent: geography.

“The Iranians have thought a lot about how to utilize the geography to their benefit,” said Caitlin Talmadge, a professor at the Massachusetts Institute of Technology who studies Gulf security.
