United States President Donald Trump said he no longer felt an “obligation to think purely of peace” after not receiving the Nobel Peace Prize, and repeated his demand for control of Greenland, in a letter to Norwegian Prime Minister Jonas Gahr Støre seen by Reuters and Bloomberg on Monday.

A copy of the text of the letter was posted by the foreign affairs and defence correspondent for PBS News, Nick Schifrin, on social media platform X, who said he had obtained it from multiple officials. Schifrin added that the letter had been forwarded to “multiple European ambassadors in Washington”.

“Dear Jonas: Considering your Country decided not to give me the Nobel Peace Prize for having stopped eight Wars PLUS, I no longer feel an obligation to think purely of Peace,” Trump said in the letter.

“Although it will always be predominant, but can now think about what is good and proper for the United States of America.”

As Bloomberg pointed out, the Nobel Peace Prize is not decided by the Norwegian government but rather awarded by an independent committee.

“Denmark cannot protect that land from Russia or China, and why do they have a ‘right of ownership’ anyway?” the US president added.

“There are no written documents, it’s only that a boat landed there hundreds of years ago, but we had boats landing there, also.”

Trump also called on the North Atlantic Treaty Organisation (Nato) to “do something for the United States”, saying, “I have done more for Nato than any other person since its founding”.

He added, “The world is not secure unless we have Complete and Total Control of Greenland. Thank you!”

“Regarding the Nobel Peace Prize, I have several times clearly explained to Trump what is well known, namely that it is an independent Nobel Committee, and not the Norwegian government, that awards the prize,” Bloomberg quoted Støre as saying in response.

A request for comment sent to the White House was not immediately returned, it added.

Trump has insisted he will settle for nothing less than full ownership of Greenland, an autonomous territory of Denmark, threatening tariffs of up to 25 per cent on eight European nations until his purchase of the Danish territory is achieved.

Meanwhile, last year’s Nobel Peace Prize winner Maria Corina Machado had given her own medal to Trump in recognition of what she called his commitment to the freedom of the Venezuelan people. However, the Norwegian Nobel Institute has said the prize cannot be transferred, shared or revoked even if the medal is given away.
