US President Donald Trump has issued a strong warning to Greenland's Prime Minister Jens-Frederik Nielsen, stating that Nielsen's public affirmation of 'we choose Denmark' would be 'a big problem for him'. This exchange marks a significant escalation in diplomatic tensions surrounding the strategically vital Arctic territory. Greenland's Premier, Jens-Frederik Nielsen, publicly declared at a joint press conference with Danish Prime Minister Mette Frederiksen in Copenhagen that if forced to choose between the United States and Denmark, Greenland would stand with Denmark, emphasizing its status as part of the Kingdom of Denmark. Trump's remarks, including the quote 'I don't know who he is. Don't know anything about him, but that's going to be a big problem for him,' came in response to Nielsen's dismissal of the prospect of Greenland becoming a US territory. The US President has repeatedly asserted that Greenland is crucial for American national security, aiming to prevent Russia or China from gaining influence in the Arctic, and has suggested the US would acquire the island 'one way or another,' even hinting at military force. This renewed push to acquire Greenland follows earlier attempts during his first presidency and comes ahead of anticipated high-level meetings between US officials and the foreign ministers of Denmark and Greenland in Washington, intended to de-escalate the standoff and repair strained ties. Both Danish and Greenlandic leaders have consistently rejected any notion of the island being for sale, stressing that Greenland's future is a matter of self-determination for its people. The situation underscores the increasing geopolitical importance of the Arctic, with several European nations expressing support for Denmark and Greenland's sovereignty against what they term 'unacceptable pressure' from the US.
