The market rollercoaster of the past week – the tariffs, the jeopardy, the brinkmanship – has highlighted the remarkable nature of an interconnected world we take for granted.
There are many frontlines in this global trade war and the port of Duluth-Superior is one. It is a logistical and an engineering wonder.
In the northernmost part of the United States, near the border with Canada, there is no seaport anywhere in the world as far inland as this.
The sea is more than 2,000 miles away, to the east, along the Great Lakes-St Lawrence Seaway System, a binational waterway with a shared border between the US and Canada.
On the portside, vast ocean-going vessels are loaded and unloaded with products which make up the lifeblood of the global economy – iron ore for Canada, cement from Turkey, grain for Algeria and shipping containers packed with “Made in China” products for the American market.

My guide is Jayson Hron from the Duluth Seaway Port Authority.
“A vessel that is sailing through the seaway to Duluth crosses the international boundary nearly 30 times on that journey,” he tells me.
Duluth-Superior generates $1.6bn (£1.2bn) a year, supports more than 7,000 jobs, and these are nervous times.
“It’s certainly a season of more unpredictability than we’ve seen in the last few years. Unpredictability is bad for ports and bad for supply chains,” Mr Hron says.
Tariffs mean friction and friction is bad for everyone. Approximately 30 million metric tons of waterborne cargo moves through the port each season, placing it among the nation’s top 20 ports in terms of cargo flow.
“Iron ore is the port’s king cargo by tonnage,” Mr Hron says. “It makes up about half of our waterborne tonnage total each year. It is mined 65 miles/104km from the port, on Minnesota’s Iron Range.”

But not all of the iron ore sails to domestic mills. Almost a third sailed to Canada in 2024, now subject to the trade war levies between the two nations.
“A fifth of our port’s overall waterborne tonnage was Canadian trade in 2024, with the vast majority of it export tonnage from the US to Canada,” Mr Hron says.
Geography combined with American and Canadian engineering over many decades has made this port a logistical wonder. From the high seas, cargo can be imported and exported to and from the heart of the North American continent.

On the dockside, the Federal Yoshino is being prepared for her cargo. She will leave here soon with American grain destined for Algeria.
The port straddles two states. The John A Blatnik interstate bridge links Duluth with Superior and Minnesota with Wisconsin.
A network of roads and rails links the port with the country beyond, and an hour to the southeast are the fields of gold in Wisconsin.
Trump suggests farmers can sell more products at home
Last year, soybeans were the biggest export from the US to China, totalling nearly $12.8bn (£10bn) in trade.
Donald Trump has suggested American farmers can make up the difference by selling more of their products at home.
In March, he posted on social media: “To the Great Farmers of the United States: Get ready to start making a lot of agricultural product to be sold INSIDE of the United States. Tariffs will go on external product on April 2nd. Have fun!”
But there is no solid domestic market for soybeans – America’s second largest crop. Two-fifths of the exports go to China. No other export market comes close – 11% to Mexico and 9% to the EU – also now facing potential tariff barriers too.

‘These fields are rows of gold’
Tanner Johnson is a local farmer and soybean industry representative. He talks regularly to politicians in Washington DC.
“They don’t look like much in your hand. But these fields are rows of gold,” he says.
Farmers across this country voted overwhelmingly for Mr Trump. Is there anxiety? Absolutely.
“I don’t want to put an exact timeline on when doors around here will close. But in the short term I think most farmers can handle it. Long-term – a year, year plus – things are going to look a lot more bleak around here,” Mr Johnson tells me.
Here, they mostly seem to hold on to a trust in Mr Trump. There remains a belief that his wild negotiating with their livelihoods will pay off. But it’s high stakes and with an uncertainty that no one needs.
Venezuela’s President Nicolas Maduro has accused the US of a coup attempt after Donald Trump approved CIA operations in the country to tackle alleged drug trafficking.
Mr Trump confirmed his decision, first revealed by The New York Times, as he said large amounts of drugs were entering the US from Venezuela– much of it trafficked by sea.
“We are looking at land now, because we’ve got the sea very well under control,” he said.
When asked why the coastguard wasn’t asked to intercept suspected drug trafficking boats, which has been a longstanding US practice, Mr Trump said the approach had been ineffective.
“I think Venezuela is feeling heat,” he said.

Maduro hits back
He declined to answer whether the CIA has the authority to execute Mr Maduro, who denies accusations from Washington that he has connections to drug trafficking and organised crime.
The US has offered a $50m (£37m) reward for information leading to his arrest.
“How long will the CIA continue to carry on with its coups?” he asked after Mr Trump’s comments on Wednesday evening, saying calls for regime change harkened back to “failed eternal wars” in Afghanistan and Iraq.
In a message to the American people, he said in English: “Not war, yes peace. The people of the US, please.”

US targets ‘drug boats’
Mr Trump also alleged Venezuela had sent a significant number of prisoners, including individuals from mental health facilities, into the US, though he did not specify the border through which they reportedly entered.
On Tuesday, he announced America had targeted a small boat suspected of drug trafficking in waters off the Venezuelan coast, resulting in the deaths of six people.
According to the president’s post on social media, all those killed were aboard the vessel.

The incident marked the fifth such fatal strike in the Caribbean, as the Trump administration continues to classify suspected drug traffickers as unlawful combatants to be confronted with military force.
War secretary Pete Hegseth authorised the strike, according to Mr Trump, who released a video of the operation.
The black-and-white footage showed a small boat seemingly stationary on the water. It is struck by a projectile from above and explodes, then drifts while burning for several seconds.
Mr Trump said the “lethal kinetic strike” was in international waters and targeted a boat travelling along a well-known smuggling route.
There has also been a significant increase in US military presence in the southern Caribbean, with at least eight warships, a submarine, and F-35 jets stationed in Puerto Rico.
‘Bomb the boats’: Bold move or dangerous overreach?
It’s a dramatic – and risky – escalation of US strategy for countering narcotics.
Having carried out strikes on Venezuelan “drug boats” at sea, Trump says he’s “looking a” targeting cartels on land.
He claims the attacks, which have claimed 27 lives, have saved up to 50,000 Americans.
By framing bombings as a blow against “narcoterrorists”, he’s attempting to justify them as self-defence – but the administration has veered into murky territory.
Under international law, such strikes require proof of imminent threat – something the White House has yet to substantiate.
Strategically, Trump’ss militarised approach could backfire, forcing traffickers to adapt, and inflaming tensions with Venezuela and allies wary of US intervention.
Without transparent evidence or congressional oversight, some will view the move less like counterterrorism and more like vigilantism on the seas.
The president’s “bomb the boats” rhetoric signals a shift back to shock and awe tactics in foreign policy, under the banner of fighting drugs.
Supporters will hail it as a bold, decisive move, but to critics it’s reckless posturing that undermines international law.
The strikes send a message of strength, but the legal, moral and geopolitical costs are still being calculated.
A 39-year-old man died in hospital alone, miles from his family, after being detained by US immigration officials.
Ismael Ayala-Uribe, who had lived in the US since he was four, fell ill while in an immigration detention centre in California.

He complained of a fever and had a persistent cough in the weeks before he died, according to his mother Lucia.
She said he was initially treated by medical staff inside the detention centre but was returned to his cell.
He was eventually taken to hospital for a scheduled surgery to remove an abscess on his buttocks, but died before he was able to have the operation.
His family were never told he was in hospital, learning of his death via a knock on the door from police.
“They’re the ones that notified us that he had passed,” his brother, Jose Ayala, told Sky News.
“We were not even aware that he was in the hospital or even had a scheduled surgery. Then we got a knock on our door a little after 5.30 one morning.
“I believe he would still be alive today if he was never detained. He got sick while in detention, and they did not seem to take care of him.”

Why was he detained?
Mr Ayala-Uribe’s death raises questions about the conditions inside the centre he was held in, and if a sudden surge of immigrants being detained by this administration has left the system stretched beyond breaking point.
He had moved to the US from Mexico with his family as a child.
He did have DACA – deferred action for childhood arrivals – status, granted to those who have arrived while under the age of 18. But this was removed in 2016, after he was convicted of drink-driving.
In August, he was arrested by immigration agents at a car wash in California where he had worked for 15 years.
He was held for five weeks at Adelanto, a privately owned, run-for-profit, immigrant detention centre. A lawyer for his family said he was, as far as they are aware, a healthy man before he was detained and had no medical need.
But Mr Ayala-Uribe’s mother, who was visiting him every eight days and speaking to him on the phone a couple of times a day, said she noticed him getting progressively unwell.

“He started with lots of fever,” Ms Ayala said. “He said they weren’t listening to him. The last time I saw him his face was drained, he told me he was not OK, he told me he couldn’t take it any more.”
Beginning to cry, wiping away tears, she added: “I feel powerless that I couldn’t do anything to help my son.
“I never imagined I was going to bury one of my sons. It feels terrible, they took a piece of my heart away.
“I would like something to change. If we cannot save him, at least we can save others that are still inside.”

Inside Trump’s immigration raids
ICE defends detention treatment
The cause of Mr Ayala-Uribe’s death is still under investigation.
Sky News requested comment from the company which owns the detention centre where he was held, and they deferred to ICE, the US immigration and customs enforcement agency.
In a statement, ICE said: “Comprehensive medical care is provided from the moment individuals arrive and throughout the entirety of their stay.
“At no time during detention is a detained illegal alien denied emergency care.”
The Trump administration says it’s targeting criminals and people in the US illegally. But campaigners say Mr Ayala-Uribe’s death should not be viewed in isolation.
Image: Images from Ismael’s funeral service
Since Donald Trump took office, at least 15 people have died in immigration detention.
Democrat senators Jon Ossoff and Raphael Warnock wrote a letter to the homeland security secretary, Kristi Noem, asking for more information about these deaths.
The senators claimed 10 people had died between January and June, and that it was the highest rate in the first six months of any year publicly available.
Sarah Houston, a lawyer for the Immigrant Defenders Law Centre, claims immigrants are being mistreated in custody.

ICE raids: ‘This is like Vietnam’
“This administration’s main goal is to harm, to torture individuals and to try to force them out,” she said.
“The great increase we see in human rights abuses, in deaths, is a direct result of the administration’s decision to pack these detention centres as much as they can.”
Mr Ayala-Uribe’s funeral was held this week. Dozens of extended family and friends wore t-shirts bearing his face. A mariachi band played as his casket was lowered into the ground and his mother heaved with sobs.
As they absorb their loss, the effort to carry out the biggest mass deportation operation in US history continues.
An aircraft carrying US defence secretary Pete Hegseth has had to make an “unscheduled landing” in the UK.
The jet was about 30 minutes into its journey back to the US after a NATO defence ministers’ meeting in Brussels, when it suffered a “depressurisation issue”.
Sean Parnell, chief Pentagon spokesman, confirmed the aircraft had been diverted to the UK due to a crack in the aircraft windscreen.
He posted on X: “On the way back to the United States from NATO’s Defence Ministers meeting, Secretary of War Hegseth’s plane made an unscheduled landing in the United Kingdom due to a crack in the aircraft windshield.
“The plane landed based on standard procedures, and everyone onboard, including Secretary Hegseth, is safe.”

The aviation news website Airlive reported the Boeing C-32A – a military version of the Boeing 757 – had a “depressurisation issue”.
It went on to land at RAF Mildenhall in Suffolk at about 7.10pm.
Mr Hegseth had been at a meeting of NATO defence ministers which was also attended by UK Defence Secretary John Healey.
In February, a US Air Force plane carrying secretary of state Marco Rubio and the Senate foreign relations committee chairman, Senator Jim Risch, was similarly forced to return to Washington DC after an issue with the cockpit windscreen.
