U.S. President Donald Trump told Norwegian Prime Minister Jonas Gahr Store that he no longer feels obligated to think “purely of peace” in his quest to take over Greenland and cited not getting the Nobel Prize last year — when he stopped wars, he said — as a sore point.

“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 can now think about what is good and proper for the United States of America,” he wrote on Sunday.

“Denmark cannot protect that land from Russia or China, and why do they have a ‘right of ownership’ anyway? There are no written documents, it’s only that a boat landed there hundreds of years ago, but we had boats landing there, also,” he added.

Trump said he has “done more for NATO than any other person since its founding, and now, NATO should do something for the United States.”

The world is not secure unless the U.S. has “complete and total control of Greenland,” he continued.

Trump said he has stopped wars between Iran and Israel, Cambodia and Thailand, Armenia and Azerbaijan, Ethiopia and Egypt, Pakistan and India, Rwanda and the Democratic Republic of Congo, and Serbia and Kosovo.

Trump also secured a deal between Israel and Hamas that led to a ceasefire and the release of hostages held by the militant organization.

Store, the Norwegian leader, acknowledged receipt of the letter from Trump, saying it was in response to a phone call request from him and Finnish President Alexander Stubb.

NATO allies are pushing Trump to a “calm discussion” around acquiring Greenland after America hit its closest European partners with tariffs over the matter. 

United Kingdom Prime Minister Keir Starmer led allies in taking a conciliatory tone on Monday, revealing Britain is not planning to consider retaliatory tariffs. His approach comes as Trump prepares to attend the annual World Economic Forum in Davos, Switzerland this week, offering Britain and other NATO countries the avenue to court Trump. 

“A tariff war is in nobody’s interests,” Starmer told reporters. “We have not got to that stage. My focus is on making sure we don’t get to that stage.”

European Union ambassadors have already discussed the situation, with representatives from the 27-nation bloc appearing to come to the conclusion during an emergency caucus on Sunday that they prefer negotiations with the White House to retaliatory actions. European leaders have upped pledges to contribute more to Greenland’s security, as France, Germany, the United Kingdom, the Netherlands, Finland, and Norway announced last week plans to get their troops to participate in joint exercises in Denmark’s territory. 

“Escalation on purpose and fiery rhetoric are not our preference — negotiations are,” a senior EU government official told Politico Playbook. “But, of course, Europe has leverage, too, and both sides need to be aware of that.”

Denmark’s defense minister and Greenland’s foreign minister were expected to meet NATO Secretary-General Mark Rutte in Brussels on Monday to discuss strategy ahead of Davos. However, on Monday morning, the World Economic Forum said Danish government officials are no longer expected to attend the Davos forum.

“Danish government representatives were invited this year, and any decisions on attendance are a matter for the government concerned,” the Forum said in a statement to Bloomberg. “We can confirm that the Danish government will not be represented in Davos this week.”

Rutte said Sunday he had spoken with Trump but provided few details, saying only that he looks forward to meeting with the president at the Davos summit. Trump is set to convene with business leaders at Davos on Wednesday evening, according to Semafor. His tariffs will likely be discussed in detail. 

Rutte was among multiple international leaders who called Trump over the weekend to express worries after the president announced 10% tariffs would be levied, effective next month, on countries for opposing his efforts to acquire Greenland. Italian Prime Minister Giorgia Meloni said on Sunday she had spoken to Trump and called the tariffs a “mistake.”  

On Sunday evening, Trump reiterated concerns about Greenland, a strategic global security asset, being vulnerable to Russian and Chinese influence, warning that “it is time” to fend off nefarious powers in the region. 

The Trump administration has expressed confidence that European allies “will come around” on the Greenland debate. 

International leaders will eventually realize that U.S. control over the Arctic island is “best for Greenland, best for Europe and best for the United States,” Treasury Secretary Scott Bessent said Sunday during an NBC interview. 

“(The tariff rollout) is a strategic decision by the president,” he said. “This is a geopolitical decision, and he is able to use the economic might of the U.S. to avoid a hot war.”
