Donald Trump has issued a warning that he might levy tariffs on countries that do not back his ambition to purchase Greenland.

“I may consider imposing tariffs on nations that don’t agree with our Greenland initiative. It is crucial for our national security,” Trump remarked to the press at the White House on Friday.

This latest assertion concerning the Danish territory coincided with the arrival of a bipartisan congressional delegation in Copenhagen. Their mission is to solidify support for the United States’ NATO ally.

Meanwhile, several countries, including Britain, Finland, France, Germany, the Netherlands, Norway, and Sweden, announced plans to send a limited number of troops to Greenland.

The delegation of 11 congress members is scheduled to engage in discussions with Denmark’s Prime Minister Mette Frederiksen and Greenland’s leader Jens-Frederik Nielsen.

‘We are showing bipartisan solidarity with the people of this country and with Greenland. They’ve been our friends and allies for decades,’ Democratic Senator Dick Durbin told reporters.  

‘We want them to know we appreciate that very much. And the statements being made by the president do not reflect what the American people feel.’

The delegation’s visit follows a meeting in Washington on Wednesday at which Danish representatives said they are in ‘fundamental disagreement’ with Trump over Greenland.

In Greenland’s capital Nuuk, residents welcomed the show of support.

‘Congress would never approve of a military action in Greenland. It’s just one idiot speaking,’ a 39-year-old union representative said.

‘If he does it, he’ll get impeached or kicked out. If people in Congress want to save their own democracy, they have to step up,’ said the union rep, speaking on condition of anonymity.

Trump claims the United States needs mineral-rich Greenland and has criticized Denmark for, he says, not doing enough to ensure its security.

The president has pursued that argument, despite strategically located Greenland – as part of Denmark – being covered by NATO’s security umbrella.

Military personnel were more visible in Nuuk on Friday, days after Denmark said it was beefing up its defense on the island.

‘I don’t think troops in Europe impact the president’s decision-making process, nor does it impact his goal of the acquisition of Greenland at all,’ White House press secretary Karoline Leavitt told a briefing.

Danish Foreign Minister Lars Lokke Rasmussen retorted that a US acquisition of Greenland was ‘out of the question’.

The European troop deployment in Greenland for a military exercise is aimed at ‘sending a signal’ to ‘everyone’, including the United States, that European countries are determined to ‘defend (their) sovereignty’, French armed forces minister Alice Rufo said.

‘A first team of French service members is already on site and will be reinforced in the coming days with land, air and maritime assets,’ French President Emmanuel Macron said on Thursday.

Large demonstrations are planned across Denmark and Greenland on Saturday to protest against Trump’s territorial ambitions.

Thousands of people have taken to social networks to say they intend to take part in the protests organized by Greenlandic associations in Nuuk and Copenhagen, Aarhus, Aalborg and Odense.

In addition to Durbin, the US delegation included Democratic senators Chris Coons, Jeanne Shaheen and Peter Welch, as well as Republicans Lisa Murkowski and Thom Tillis.

Democrats from the House of Representatives in the delegation are Madeleine Dean, Steny Hoyer, Sara Jacobs, Sarah McBride and Gregory Meeks.
