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.

The quiet-spoken Canadian prime minister has spoken unutterable truths

Is it perhaps a sign of the times that Mark Carney, the prime minister of Canada, has become a thrilling orator? A sober banker, he speaks calmly, without many vocal inflections. We expect Canadians to be somewhat flat; even a little boring, and yet Carney has already delivered two remarkable speeches in 2026, and the year is far from over.

The first, at Davos, described a “rupture in the world order”, and “the end of a pleasant fiction”. By that, he meant that the world could no longer depend on the United States to lead the Pax Americana that has largely kept the peace since the end of the second world war.

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.

Everyone can see that the Iran war has been a strategic disaster for the US, while a failing president pretends he is winning

Now is the twilight of Donald Trump’s supremacy. The US is still the richest and most heavily armed nation on Earth. That status is secure. The current president, contemptuous of law and indulged in lawlessness by a supine Congress, enjoys even greater power than the constitution allows.

With those advantages it takes a special talent for incompetence to look as thwarted and impotent as Trump does with more than two years of his second term still to run.
