US President Donald Trump has refused to say how far he will go on Greenland, but suggested that he could make a deal as European leaders voice alarm over his threats to seize the territory from ally Denmark.
Asked hours before he was to head to the World Economic Forum in Davos, Switzerland, how far he would go, Mr Trump replied only: "You'll find out."
"We have a lot of meetings scheduled on Greenland, and I think things are going to work out pretty well," Mr Trump told reporters about his Davos meetings.
Denmark has warned that the entire NATO alliance is at risk if Mr Trump moves forward on threats. Over the weekend, Mr Trump vowed fresh tariffs on European countries including Britain, France and Germany which sent troops to Greenland in solidarity.
He dismissed suggestions that he was putting at risk a deal last year with the EU in which the allies promised to ramp up investment in the US, saying: "They need that agreement very badly with us."
"I think that we will work something out where NATO is going to be very happy and where we're going to be very happy.
"But we need it for security purposes. We need it for national security and even world security," Mr Trump said of Greenland.
Timeline: Major developments in Donald Trump's trade war
Greenland's leadership has repeatedly said that the vast but sparsely populated island is not for sale.
Asked about the broad opposition to his designs among Greenland's population, he said: "When I speak to them, I'm sure they'll be thrilled."
Mr Trump has said that the US needs Greenland, which would dramatically increase the US land mass, because of a threat of Russia or China seizing the island as climate change opens up Arctic water routes.
Neither of the two rival powers claims Greenland, and Denmark has said that China has no major investment and has not recently sent any warship to Greenland.
This evening, Tánaiste Simon Harris said "everything is on the table" in relation to how Europe may respond if the US was to "annex" Greenland or part of Greenland.
Speaking on RTÉ's Six One News, Mr Harris said any action taken at a European level would be proportionate, but he warned against getting involved in a "spiral" of "tit-for-tat tariffs".
Trump marks first year back with familiar grievances
The US president marked the first anniversary of his return to the White House with a rambling, often downbeat news conference that leaned heavily on familiar grievances rather than celebration.
Opening with a lengthy critique of illegal immigration, Mr Trump launched into a monologue covering a wide range of subjects - from US military action in Venezuela and welfare fraud by Somali immigrants in Minnesota to repeated attacks on his predecessor, Joe Biden.
As Mr Trump lurched from subject to subject, the address felt less like a victory lap than a reprise of the campaign that preceded his return to office.
This included his false claim - unprecedented for US presidents - to have won the election which he lost to Mr Biden in 2020.
"We've done more than any other administration has done, by far, in terms of military, in terms of ending wars, in terms of completing wars," said Mr Trump, who returned to office on 20 January last year after defeating Democratic then-vice president Kamala Harris in the 2024 presidential election.
"Nobody's really seen very much like it," he added.
White House aides circulated a 31-page document listing 365 claimed "wins" across immigration, the economy and foreign policy, as reporters packed the briefing room.
The president repeated a series of claims long disputed or debunked, including that his 2020 election loss was "rigged," that prescription drug prices had fallen by 600% - a mathematical impossibility - and that the US had attracted $18tn in inward investment.
At various points, Mr Trump described himself as a "financial genius" and faulted his own staff for failing to adequately communicate what he portrayed as major successes in bringing down inflation.
On foreign affairs, the Republican signalled an interest in working with Venezuelan opposition leader Maria Corina Machado on the country's future, following Washington's 3 January military operation that removed Nicolás Maduro from power.
"We're talking to her," Mr Trump said. "Maybe we can get her involved in some way. I'd love to be able to do that."
He praised Ms Machado for giving him her Nobel Peace Prize medal, complaining again that the Norwegian committee should have honored him instead.
