Greenland should consider rejoining the European Union for “protection” in the face of U.S. President Donald Trump’s threats to acquire the Arctic island, Danish MEP Morten Løkkegaard said Wednesday. While Løkkegaard said Greenland’s future was ultimately for Greenlanders to decide, he argued it was time for “some kind of new thinking.”

The Danish PM's tour of three capitals betrayed the nervousness felt in Denmark over Trump's repeated comments.

Frederiksen didn't directly mention Trump's threat in comments at a meeting with German Chancellor Olaf Scholz, but said that “we are facing a more uncertain reality, a reality that calls for an even more united Europe and for more cooperation.

Denmark said on Friday it meant seriously that Greenland is not for sale, after Secretary of State Marco Rubio said U.S. President Donald Trump's interest in acquiring the island was "not a joke".

Denmark said on Monday it would spend 14.6 billion Danish kroner ($2.05 billion) boosting its military capabilities in the Arctic – a decision that comes amid continuing furor following US President Donald Trump’s renewed interest in controlling Greenland,

The secretary of State said purchasing the Danish territory is important to the country’s national interests in the Arctic.
