U.S. President Donald Trump has again insisted that Greenland should become part of the United States, reaffirming his stance despite Denmark’s call to stop making “threats” over the issue. Speaking to reporters aboard Air Force One en route to Washington, Trump said Greenland was essential for U.S. national security and that Denmark could not fulfill that role. His comments came as U.S. military intervention in Venezuela heightened European concerns about Washington’s global ambitions.

The controversy deepened after Katie Miller, wife of a senior Trump adviser, posted an image of Greenland’s flag recolored with the U.S. flag’s design and captioned “Soon,” sparking anger in Denmark and the European Union. Danish Prime Minister Mette Frederiksen called the idea of taking control of Greenland “completely unreasonable” and urged Washington to stop threatening its historic ally. Greenland’s Prime Minister Jens-Frederik Nielsen described Miller’s post as “disrespectful,” emphasizing that his country was not for sale and that its future would not be decided on social media.

Denmark’s ambassador to the U.S., Jesper Møller Sørensen, reminded that Denmark is a NATO member working closely with Washington on Arctic security, urging continued cooperation as allies.
