Denmark considered U.S. one of its closest allies. Now many Danes are refusing to buy American

When Mette Vennegaard, a retired psychologist living north of Copenhagen, wanted to clear her pantry of all American products, she wrote to Denmark's largest manufacturer of candy and chocolate, Toms Group, asking where the company sourced its almonds from for its popular marzipan products.

Marzipan, a sweet paste made out of ground almonds, is a popular filling in chocolate and a key ingredient in some of Denmark's most beloved desserts.

When the company replied that its supply came from California, which produces 80 per cent of the world's almonds, Vennegaard put the product on her "do not buy list."

She then went even further, posting the letter from the company in a Facebook group, urging other Danes to steer clear as well.

"I investigate the ownership of all kinds of different products," she told CBC News. "If they are American, they do not go in the shopping basket."

Vennegaard is part of a surging group of Danes who are trying to cut or reduce the number of American products and services they use — a protest against U.S. President Donald Trump and specifically what appears to be his obsessive determination to take over Greenland, an autonomous territory that is part of the Kingdom of Denmark.

Tens of thousands of Danes have joined a Facebook group dedicated to sharing advice about how to avoid American-made products and instead buy local.

People post about cancelling their trips to the United States or their subscriptions to American streaming services.

Others look for shopping tips, like one woman who wanted to know whether Miracle Whip, a mayonnaise-like condiment, was made in the U.S. and, if so, what a suitable substitute would be.

While the boycott group is a grassroots movement, political experts say it taps into the current mood in Denmark, where the population of nearly six million feels alienated and even threatened by the messaging coming from the U.S., a country that it has previously considered one of its strongest allies.

Trump has repeatedly vowed to annex mineral-rich Greenland, promising its 56,000 residents that Washington could make them rich. In his marathon speech to the U.S. Congress earlier this month, the president said the U.S. would get it "one way or the other."

Usha Vance, the wife of U.S. Vice-President JD Vance, was supposed to visit Greenland this week to take in cultural sites and a dogsled race, but after officials in the region called it a "provocation," the trip's itinerary was scaled back.

Vance, who will now be joined by her husband, will only be visiting Pituffik Space Base, a remote U.S. military installation in Greenland's northwest that handles missile defence and space surveillance.

While officials from Greenland and Denmark are viewing the change in itinerary as a win, there is still deep concern about what Trump has said and what he might be intending on doing.
