The president's push to gain control of Greenland, a Danish territory, has created anxiety about the future of the alliance throughout Europe.

The Danish prime minister arrived in Greenland on Friday for talks on the island’s future after President Donald Trump seemingly deescalated his threats to take over the Arctic territory.

President Donald Trump’s Wednesday speech at the World Economic Forum in Switzerland was filled with inaccurate claims – notably including false and misleading statements about NATO and Greenland, the self-governing Danish territory he is pushing for the US to acquire.

The European Union’s top official has described U.S. President Donald Trump’s planned new tariffs over Greenland as a “mistake” between long-standing allies and called into question Trump’s trustworthiness.

The drills are slated to get underway against a backdrop of uncertainty about the future of relations between the U.S. and its longstanding allies.

A spokesman for Britain's prime minister, Keir Starmer, has said President Trump was wrong to diminish the role of NATO troops during the war in Afghanistan. There's been an angry backlash to the US president's claims that NATO allies avoided the frontline during the conflict.

US President Donald Trump has once again questioned whether NATO allies would “be there” if the United States “ever needed them,” claiming that the alliance’s troops “stayed a little back” from the frontlines in Afghanistan.

NATO ‌Secretary ​Mark Rutte said ‌on Thursday that he and U.S. ​President Trump had discussed in Davos how the ‍transatlantic alliance should best ​defend the Arctic against Russia and China. Trump ​has ⁠repeatedly said he wanted to acquire Greenland,
