A bipartisan U.S. congressional delegation on Saturday sought to reassure Denmark and Greenland of their support following President Donald Trump’s threat to punish countries with tariffs if they don’t back the U.S. taking over the strategic Arctic island.

Delegation leader Sen. Chris Coons, a Delaware Democrat, said the current rhetoric around Greenland is causing concern across the Danish kingdom. He said he wants to de-escalate the situation.

“I hope that the people of the Kingdom of Denmark do not abandon their faith in the American people,” Coons said in Copenhagen, adding that the U.S. has respect for Denmark and NATO “for all we’ve done together.”

Meanwhile, Danish Major Gen. Søren Andersen, leader of the Joint Arctic Command, told The Associated Press that Denmark does not expect the U.S. military to attack Greenland, or any other NATO ally, and that European troops were recently deployed to Nuuk for Arctic defense training.

He said the goal isn’t to send a message to the Trump administration, even through the White House hasn’t ruled out taking the territory by force.
