Donald Trump's threat of additional tariffs on eight European countries over Greenland prompted EU discussions on retaliatory measures. But EU-US relations are not the only ones taking a hit - the crisis could have deep repercussions on the NATO alliance.
An intense week of diplomacy kicks off on Monday as European leaders try to find a common position to counter Donald Trump's threat of additional tariffs on countries that do not support the US takeover of Greenland.
A lot of meetings, including between Europeans and Americans, are set to take place on the sidelines of the World Economic Forum in Davos, where world leaders will gather this week.
EU leaders will meanwhile convene in Brussels for an extraordinary summit later this week.
Ambassadors from across the bloc already had a first conversation at 27 on the topic on Sunday evening where the European Commission presented several options to hit back at the US, including the introduction of a list of retaliatory measures worth €93 billion and the activation of the Anti-Coercion Instrument, which would allow broader retaliation in other economic sectors and levers. The tool has never once been triggered.

As Europeans bet on diplomacy, Trump doubles down on annexation
Europe's push for diplomacy is already off to a rough start. In an overnight message, Donald Trump doubled down on his desire to annex Greenland and make the sprawling island part of the United States.
"NATO has been telling Denmark, for 20 years, that 'you have to get the Russian threat away from Greenland.' Unfortunately, Denmark has been unable to do anything about it. Now it is time, and it will be done!!!" Trump wrote on Truth Social.

Trump tells Norway PM: 'I no longer feel obliged to think of peace’ after Nobel Prize snub
In an explosive letter sent to Norwegian Prime Minister Jonas Gahr Stør, US President Donald Trump has linked his ambition to gain control of Greenland to his failure to secure the Nobel Peace Prize.
In a letter styled as a Truth Social post, Trump said: “Dear Jonas, Considering your Country decided not to give me the Nobel Peace Prize for having stopped 8 Wars PLUS, I no longer feel an obligation to think purely of Peace, although it will always be predominant, but I can now think about what is good and proper for the United States of America."
The letter was first reported by PBS News Hour correspondent Nick Schifrin. Norwegian media VG has since said that Prime Minister Stør has confirmed the veracity of the letter to them.
Trump has repeatedly said he deserves the Nobel Peace Prize and has lashed out at Norway for refusing to award it to him. The 2025 prize was given to Venezuelan opposition leader Maria Corina Machado, who last week gave Trump her Nobel medal during a closed-door meeting in the White House.
Norway is among the eight European countries targeted with additional tariffs by Trump over the weekend over their support to Greenland.
Nordic defence ministers to meet later today
Defence ministers from Nordic countries will also meet today at NATO headquarters in Brussels, the Danish defence ministry said in a statement.
Reminder: Troels Lund Poulsen, Denmark's defence minister, and Vivian Motzfeldt, Greenland's foreign affairs and research minister, are scheduled to meet with NATO chief Mark Rutte at 16.30 CET today.
"Greenland is in an extraordinary situation that has the attention of the whole world. The situation requires that we strengthen cooperation on defence and security in the Arctic broadly within the NATO circle. I look forward to discussing the way forward with NATO's Secretary General and with my Nordic colleagues in Brussels," Motzfeldt said in a statement.
Poulsen meanwhile said that the discussions with Nordic ministers will focus on how NATO can do more in the Arctic.
“The Danish and Greenlandic governments, together with a number of NATO allies, have decided to increase the military presence and exercise activity in the Arctic and the North Atlantic. A number of allies are already contributing, and we are meeting broad support for NATO to do more in the Arctic," he said.
EU lawmakers call to freeze EU-US trade deal
Leaders from the European Parliament’s pro-EU majority are calling to suspend the EU-US trade agreement struck last summer after US President Donald Trump stepped up pressure on the bloc over Greenland, threatening to impose 10% tariffs on goods from several EU member states.
“The EPP is in favour of the EU–US trade deal, but given Donald Trump’s threats regarding Greenland, approval is not possible at this stage,” the group's president, Manfred Weber (Germany), wrote on Saturday on X, adding: “The 0% tariffs on US products must be put on hold.”
The European People’s Party is the largest political group in the Parliament.
Calls to freeze the deal also came from the Socialists & Democrats (S&D) and Renew, both part of the parliamentary pro-EU majority.
“The EU will not bow to intimidation,” S&D President Iratxe García Pérez wrote on X, while Valérie Hayer, who leads the liberal Renew group, wrote that "it is now time to move from a logic of dependence to a logic of deterrence."
“@RenewEurope cannot vote in favour of the EU–United States Turnberry trade agreement," she added.
The EU-US deal was concluded after weeks of trade tensions in 2025. Described as a “humiliation” by some European lawmakers, it includes 15% US tariffs on EU goods, while the EU committed to cutting most of its tariffs on US products to zero.
Members of the Parliament’s trade committee were due to vote this week on legislation implementing the EU tariff cuts.
US takeover of Greenland would be 'death knell' of NATO: Pedro Sánchez
Spanish Prime Minister Pedro Sánchez warned on Sunday that a US invasion of Greenland would be the "death knell" of the NATO military alliance.
Reminder: Both the US and Denmark are NATO allies.
"Greenland is not a real estate whim. It is a territory that has its sovereignty, that has its rights, and if anyone has to decide the future of Greenland, it will have to be its people, and in this case, Denmark," Sánchez told Spanish media outlet La Vanguardia in an interview.
He also said such an action by the US would make Russian President Vladimir Putin "the happiest man in the world" because "it would somehow legitimise his invasion and unilateral action and questioning of Ukraine's territory".
"Europe is naturally interested in constructive transatlantic relations, but not on the basis of vassalage, but rather on an equal footing. Europe is interested in ensuring that the national sovereignty and territorial integrity of nations are respected," Sánchez also said.

What is the anti-coercion instrument?
Often dubbed the EU’s trade “bazooka,” the anti-coercion instrument was adopted in 2023 to counter economic pressure from third countries, with the US and China in mind. Activating it requires a qualified majority of member states.
The tool allows the EU to go beyond traditional retaliatory tariffs, including by restricting licenses, intellectual property rights or access to public procurement tenders.
Targeting US services has been raised repeatedly over the past year as Washington stepped up tariff threats against the bloc before a trade deal was reached last summer. The US runs a services trade surplus with the EU, making the bloc’s 500 million consumers a key market for American companies.
The anti-coercion instrument is designed as a last-resort measure, with any steps taken required to be “proportionate” to the damage suffered by the EU or an individual member state.

Rutte to meet with Danish, Greenland ministers this afternoon
Here's an important meeting to monitor today: NATO chief Mark Rutte will receive Danish Defence Minister Troels Lund Poulsen and the Minister for Foreign Affairs and Research of Greenland, Vivian Motzfeldt.
The meeting, which was announced on Friday before Trump revealed his plan to levy an additional 10% tariffs on eight European countries over Greenland, is set to start at 16.30 CET.
No media opportunity is foreseen.
Rutte last week rejected claims the military alliance he leads is in crisis over Washington's bid to acquire Greenland, telling reporters instead that allies were evaluating the "next steps" in order to boost security in the High North and Arctic.
Europeans bet on diplomacy to avoid the worst-case scenario
European leaders are poised to continue working the phones on Monday to intensify diplomatic efforts and prevent Donald Trump's 10% tariff threat from becoming a reality.
British Prime Minister Keir Starmer, Italian Prime Minister Giorgia Meloni and NATO Secretary General Mark Rutte were among the first ones to speak direclty with Trump in a bid to contain the spiralling crisis over Greenland's future. We can expect other leaders to attempt a similar outreach in the coming hours and days. Meanwhile, António Costa, decided to convene an extraordinary EU summit for later this week after spending the weekend calling presidents and prime ministers across the bloc.
Diplomats in Brussels underscore the extreme gravity of the challenge posed by Trump's annexationist agenda but say hope is not all lost and diplomacy still has a role to play. Many European leaders will be present at the World Economic Forum in Davos, Switzerland, where Trump is expected to make a much-talked-about appearance. We will keep an eye out for any possible bilateral or multilateral meetings.
What can the EU do to retaliate?
EU countries on Sunday night reviewed their options to respond to threats by US President Donald Trump to impose 10% tariffs on several member states from 1 February unless they allowed him to acquire Greenland.
Diplomacy was agreed to take precedence over immediate countermeasures, though a decision on whether to revive the €93 billion retaliation package - suspended last year - is to be taken after Trump’s deadline.
Among the tools discussed was also the EU’s anti-coercion instrument, often dubbed as its trade “bazooka,” though no vote was held on whether to deploy it.

UK PM to address nation at 10.15 CET
British Prime Minister Keir Starmer is to address the nation at 10.15 CET on the issue.
The speech from Downing Street comes after Starmer spoke with multiple of his counterparts on Sunday including Danish Prime Minister Mette Frederiksen, European Commission President Ursula von der Leyen, and NATO Secretary-General Mark Rutte.
According to the British read-out of the calls, Starmer said that applying tariffs on allies for pursuing the collective security of NATO allies is "wrong" and that security in the High North is "a priority for all NATO allies in order to protect Euro-Atlantic interests."
We will, of course, live blog his speech later this morning.
Analysis: With one post, Trump brings the transatlantic alliance to the brink
With just one single post on his social media account, US President Donald Trump has brought the transatlantic alliance, and the security order that was forged at the end of World War II and has endured countless political shifts, to the brink of collapse. Trump has openly threatened eight allied countries with a 10% tariff to force them into giving up Greenland, a semi-autonomous territory that belongs to the Kingdom of Denmark and that refuses to be sold to the highest bidder.
"This Tariff will be due and payable until such time as a Deal is reached for the Complete and Total purchase of Greenland," Trump wrote on Saturday.
Though we are still days away from knowing whether the tariff threat materialises or vanishes, the mere fact that it has been made cuts through the foundations that underpin the transatlantic alliance, most notably the principle of collective defence, which, until now, has acted as a powerful deterrent against foreign attacks. If the US is able, and willing, to threaten another NATO member with outright annexation, can the other allies expect the US to abide by its obligation in a future conflict? After all, collective defence is based on trust and reliability, so if the expectation disappears, what is the point of the alliance? Can NATO deter Russia's expansionism in the East while it counters Trump's expansionism in the West?
It cannot be understated that this is a situation of extraordinary gravity that will compel Europeans to reckon with their long-standing dependency on America's security umbrella and take painful decisions that, until Trump's re-election, would have seemed unthinkable. The days ahead could very well become a watershed chapter that structurally redefines the 80-year-old bond between the two sides of the Atlantic. That is, if that bond manages to survive.
