A grassroots movement across Europe and Canada to boycott U.S. products is gaining momentum as people join Facebook groups to exchange ideas about how to avoid American products and find alternatives. Feelings are especially strong across the Nordic region -- and very possibly strongest in Denmark given President Donald Trump's threats to seize Greenland.

That's where Ivan Hansen, a retired Danish police officer, loaded up his basket at the supermarket, carefully checking each product to avoid buying any U.S. products. No more Coca-Cola, no more California Zinfandel wine or almonds.

The 67-year-old said it's the only way he knows to protest Trump's policies. He's furious about Trump's threat to seize the Danish territory of Greenland, but it's not just that. There are also the threats to take control of the Panama Canal and Gaza. And Trump's relationship with Elon Musk, who has far-right ties and made what many interpreted as a straight-armed Nazi salute.

On his recent shopping trip, Hansen returned home with dates from Iran. It shocked him to realize that he now perceives the United States as a greater threat than Iran.

"Trump really looks like a bully who tries in every way to intimidate, threaten others to get his way," he said. "I will fight against that kind of thing."

Google trends showed a spike in searches for the term "Boycott USA," and "Boycott America," as Trump announced new tariffs, with the top regions including Denmark, Canada and France. At the same time, a global backlash is also building against Tesla as the brand becomes tied to Trump, with plunging sales in Europe and Canada. In Germany, police were investigating after four Teslas were set on fire Friday.

Elsebeth Pedersen, who lives in Faaborg on the Danish island of Funen, just bought a car and made a point of not even looking at U.S.-made options.

"Before Elon Musk started to act like a maniac a Tesla could have been an option. And maybe a Ford," she said.

French entrepreneur Romain Roy said his solar panel firm has bought a new Tesla fleet each year since 2021 but canceled its order for another 15 to take a stand against Musk's and Trump's policies.

Describing the United States as "a country closing in on itself," he cited Trump's withdrawal from the Paris climate accord and Musk's arm gestures. He said he was instead buying European models, even though it would cost an additional $164,000.

"Individual consumers, society, our countries, Europe must react," he told broadcaster Sud Radio.

Responding to consumer demand, Denmark's largest supermarket chain, the Salling Group, created a star-shaped label this month to mark European-made goods sold in its stores. CEO Anders Hagh said it's not a boycott, but a response to consumers demanding a way to easily avoid American products.

"Our stores will continue to have brands on the shelves from all over the world, and it will always be up to customers to choose. The new label is only an additional service for customers who want to buy goods with European labels," he said in a LinkedIn post.

For Bo Albertus, "when Trump went on television and said he would by political force or military force take a piece of the Danish kingdom, it was just too much for me."

The 57-year-old said he felt powerless and had to do something. He has given up Pepsi, Colgate toothpaste, Heinz ketchup and California wine, and replaced them with European products.

Albertus, a school principal, told the Associated Press he really misses the strong taste of Colgate. But he's been pleasantly surprised at finding a cola replacement that is half the price of Pepsi.

The French are also expressing their anger.

Edouard Roussez, a farmer from northern France, launched an online group, "Boycott USA, Buy French and European!" that in just two weeks has attracted over 20,000 members on Facebook.

Roussez believes a boycott of U.S. companies is a good way to express opposition to Trump's policies, especially "the commercial and ideological war" he believes Trump is waging against Europe.

"First of all, these are the companies that financed Donald Trump's campaign," he said on state-owned LCP television channel. "I'm thinking of Airbnb, I'm thinking of Uber, I'm thinking of Tesla, of course."

The irony of it all? The group is on Facebook. Roussez said only the American online social media platform gave him the reach he needed. But he's working to migrate the group to other platforms with no U.S. funding or capital.

As for any impact on U.S. export profits or policymaking, that's unlikely, said Olof Johansson Stenman, a professor of economics at the University of Gothenburg.

The boycott could have a psychological effect on Americans who see the scale of anger, but "some may also say, 'We don't like these Europeans anyway,'" Stenman said.
