The US president’s need to assert dominance is igniting patriotism abroad and a backlash at home

What do bullies do when someone stands up to their bullying and punches them in the face? They look for someone weaker to bully who won’t punch back.

Presumably that’s why Donald Trump has now taken on Canada, after Iran punched back so hard in the cage match the US president began more than six months ago as to leave him humiliated and baffled.

Canadian PM is set to retaliate against tariffs levied by Donald Trump and criticized US officials over insults

• US politics live – latest updates

Mark Carney has rebuked Donald Trump’s administration and urged officials in Washington to “start being serious” amid escalating trade tensions between the US and Canada.

Days before Canada is due to retaliate against Trump’s sweeping tariffs with its own duties on US goods, the Canadian prime minister criticized US officials for insulting his country. “It is beneath their office,” he said.

Donald Trump ⁠on Sunday said NBC’s Kristen ‌Welker – host of Meet the Press – should face “rebuke or punishment” from the Federal Communications Commission (FCC).

Welker, during a live segment for a local Washington DC affiliate, described the success record of political candidates whom the president had endorsed as “mixed”. The segment aired prior to Sunday’s edition of Meet the Press.

There’s little optimism about treasury secretary’s ability to handle Trump’s tariffs, Iran sanctions and colossal US debt

History remembers Gen Dwight Eisenhower, the supreme commander of the allied forces in Europe during the second world war, for his role in the D-day invasion of Normandy. Whether Scott Bessent will achieve similar posterity as the face of the “economic D-day” in Iran remains to be seen.

The US treasury secretary, already trying to manage a $40tn national debt pile, this week took charge of Donald Trump’s effort to reverse-engineer his war of choice. Whereas the US would typically take on an adversary with diplomacy, sanctions and military force, in that order, the US president started with a six-month bombing campaign and now hopes that economic isolation can finish the job.

Avoiding US goods and services – from tech to whisky to air travel – has forced many to find a new way of living

For William McDonald, 38, a diesel mechanic from Thunder Bay, Ontario, “Canadian is always the first choice,” even if it means his weekly bills are higher.

“As soon as Trump started putting those tariffs on in February [last year], I started boycotting US goods,” he said. “Avoiding American products has driven my costs up, and I’m still happy to do it.

A reminder that we are covering the latest out of Jackson Hole, Wyoming, where Kevin Warsh – the new chair of the Federal Reserve – will deliver his first speech as the head of the US central bank at the annual economic policy symposium.

As my colleagues note, Warsh is under pressure to provide clarity on how the Federal Reserve should handle with inflation if price pressures don’t abate.

Every day $1bn worth of goods crosses the river dividing Detroit, Michigan, and Windsor, Ontario, two largely blue-collar US and Canadian cities that have come to act as one in the creation of North America’s auto industry.

News this week of Donald Trump’s escalating trade spat with Canada has everyone worried. Political and economic leaders and observers labeled the move an act of “hubris” , blamed Trump’s “ego”, and called the escalation “insanity”.

The US president expected Ottawa to bow to tariff demands, but Canada is striking back – and it could cost Americans

Earlier this year, a survey found that Canada, along with Switzerland, was the best-liked country in the world. We all know this kind of polling is about as scientific as a high school popularity contest, but at least anecdotally, Canadians have a reputation for being friendly and welcoming, respectful and polite. Many people would find it difficult to dislike Canadians.

But not Donald Trump, who in a “hold my beer” moment this week demonstrated that he, at least, finds it easy to resent Canadians. The US president called the country “difficult and unreasonable”, and in a particularly hysterical moment, threatened to rename a lake, after trade talks collapsed.

Paper products among hardest-hit sectors after trade negotiations broke down, with 25-50% tariffs estimated

• Are you a Canadian boycotting US products? We’d like to hear from you

Using the bathroom or having a cry is about to become more expensive for North Americans as the US and Canada enter a full-fledged trade war that threatens to flush away decades of peaceful trading between the two nations.

After trade negotiations broke down between the two countries last weekend, Mark Carney, the Canadian prime minister, vowed to match US tariffs “dollar for dollar” and unveiled a list of nearly 900 American goods that will face 25% to 50% tariffs starting on 8 September.

• Bessent ‘will lose’ battle with bond markets, ex-mentor warns

Are we seeing the first signs of panic in Donald Trump’s Treasury? The US is by far the world’s biggest debtor, and the steady rise in global long-term interest rates – which I have long argued was inevitable – is starting to cause real pain.

Until now, the Treasury secretary, Scott Bessent, has dismissed concerns about US debt, which recently surpassed $40tn, as a big nothingburger. Growth, in his telling, will be so spectacular the US will easily be able to meet its interest obligations without any significant tax rises or spending cuts, while the rest of the world will happily keep feeding it money. But if Bessent really believes that, why is he trying to strong-arm the bond market by fiddling with the maturity structure of government debt?

Ottawa’s ‘focused response’ to levies imposed by Donald Trump on Canadian products comes after trade talks collapsed last week

• US politics live – latest updates

Canada has announced it will impose tariffs on a wide range of key American industries including cosmetics, dairy, wood products and outdoor equipment in the coming weeks, as it retaliates roughly “dollar for dollar” against levies imposed by the US.

In a strong Canadian countermove to tariffs levied by Donald Trump, which took effect on Saturday after trade talks collapsed the day before, Canada’s finance and industry ministers on Tuesday called the measure a “focused response” to what they see as unfair trade practices.

Tariffs on Canada, threats against Iran’s partners and bond market intervention show a president weaponising US power while making Americans poorer at home

Three moves in the last week have exposed the limits of Donald Trump’s economic bullying. The US slapped 50% tariffs on another $20bn of Canadian goods – then threatened the same rate on the cars, trucks, parts and steel that America Inc depends on. On Monday, the Treasury secretary, Scott Bessent, menaced Iran’s trading partners with exclusion from the US financial network, hoping that coercion can deliver what months of war have not. And as the costs of war, tariffs and pro-billionaire tax cuts helped send US bond yields higher, the Treasury stepped in to tame long-term rates. These are not contradictory policies but a gamble: that US economic power can be repeatedly weaponised without reducing others’ willingness to depend on it.

The Trump administration’s “D-day” sanctions are potentially the most consequential because they expose the scaffolding of American financial power. While markets shrugged off the immediate threat, that calculation might change were the US to target a major Chinese refinery or bank. Such an escalation could spark a trade war with Beijing. The US has leverage. But China has pressure points – especially farmers in Republican states – that make using it costly. In the long run, there is a price to pay. Nations hold one another’s currencies partly because they trust the political relationship. Mr Trump is testing what happens when they don’t.

On Truth Social, however, the president shot down assertions that the US talks with Canada collapsed in part due a proposed trade deal that would have weakened French language protections.

“I would never interfere with Canadians speaking French!” he wrote. “In fact, I have never even thought of doing such a stupid thing. This lie was made up by a weak and ineffective Prime Minister in an attempt to gain political support, which he has totally lost, from the people of Quebec.”

Prime minister praised for rejecting US trade proposal as Trump shows little interest in retreating from dispute

• Are you a Canadian boycotting US products? We’d like to hear from you

Mark Carney said on Monday that while American negotiators saw the French language in Canada as an “irritant … in Quebec, these are rights,” days after receiving widespread praise from political leaders for rejecting a US trade proposal that many perceived as weakening the country’s Francophone culture.

The prime minister’s remarks came hours after the US president, Donald Trump, showed little interest in retreating from the spat, posting on social media that Canada had been “ripping off the United States of America for years” and threatening a swath of new, economically devastating tariffs on cars and trucks.

• ‘No more!!!’: Trump lashes out after US-Canada talks devolve into trade war

The calamitous collapse of trade negotiations between Canada and the United States is a warning to nations worldwide that pursuing any kind of dialogue with the current US administration is doomed at the outset, according to observers who say this recent episode indicates seeking a fair deal is futile.

Andrea Lawlor, an associate professor of political science at McMaster University in Ontario, said: “No matter the closeness of the historical relationship, the American administration has signalled that it now prioritises its interests above those of some sort of global economic coordination or harmony.

Collapse of trade talks could lead to job losses, but biggest impact on traditional allies is expected to be political

The US has imposed 50% tariffs on some goods from Canada, and Mark Carney, the country’s prime minister, has vowed to match them “dollar for dollar” after the collapse of trade talks.

The tariffs came into force on roughly $20bn (£14.6bn) of goods – ranging from hockey sticks to tongue depressors – at 04.00GMT. Trade experts said the tariffs could result in some job losses, but the largest impact is expected to be political, driving a further wedge between the traditional allies.

Leaked audio from a private event has reportedly captured the US vice-president, JD Vance, mocking Canada for apparently capitulating in a trade deal and taunting the prime minister, Mark Carney, for trying to “out-tough” Donald Trump.

The recording, which was reportedly made at a fundraiser and shared with the Canadian Press, comes in the last stretch of a difficult negotiation in which the US president has threatened to impose 50% tariffs on Canada.

US president delays 50% tariffs by three days, and says contentious oil project ‘may be awoken from the grave’

Canada has temporarily avoided a bruising 50% US tariff, reaching a Tuesday-evening agreement with Trump administration officials hours before a hike that would have affected $20bn worth of goods was set to take effect.

Donald Trump posted late on Tuesday on social media that he had paused the tariffs for three days “based on the fact that Canada and the USA, subject to the finalization of documents, have a DEAL!”

Imports this year now account for 14% of the market amid claims vehicles are being dumped in the EU and UK

Chinese electric car sales have risen across Europe to a record high driven by strong demand and low tariffs in the UK and a surge in buyers in Italy.

Against a backdrop of claims that Chinese carmakers are “dumping” state-subsidised vehicles in the EU and UK to gain market share, the figures will give impetus to calls for quotas and higher tariffs to protect European manufacturers.
