Trump's announcement of a 'framework of a future deal' marks a shift after weeks of threats from the United States. Here's what we know.

Trump’s envisioned multilayered “Golden Dome” could include space-based sensors to detect missiles. They could reduce the U.S. need for its Greenland-based radar station, said Marcuz, a former nuclear defense worker for France’s Defense Ministry, now with the Foundation for Strategic Research think tank in Paris.

The U.S. military announced aircraft would soon arrive at Pituffik Space Base in Greenland, while stressing it is part of a "long-planned" exercise.

President Trump backed down on Wednesday from his threats to acquire the whole of Greenland by force if necessary and impose new tariffs on any European allies who resist his expansionist efforts, saying instead that he had reached the “framework” of a deal with NATO over the future of the massive,

"All the United States is asking for is a place called Greenland, where we already had it as a trustee, but respectfully returned it back to Denmark not long ago," Trump said.

Negotiators have discussed proposals to check Russian and Chinese influence in the Arctic and transfer sovereignty over pockets of Greenlandic land to the United States, an idea opposed by Denmark.

President Trump conceded the U.S. may not end up taking over Greenland, but said he's "getting everything" he wanted out of the Danish territory.

When President Trump posted on Truth Social Wednesday afternoon that he had reached a tentative agreement with NATO Secretary General Mark Rutte to satisfy Trump’s demand for Greenland to be annexed to the United States, he provided few details about the terms of the deal save that he was withdrawing his tariff threats against Europe.

Staunch NATO allies Denmark and Iceland are "dismayed, angry and saddened by being bullied by the United States," Sen. Dick Durbin said.

During a speech Wednesday at the World Economic Forum in Davos, Switzerland, President Trump said that he would not use force to take Greenland, an island the State Department says the United States needs to control to counter threats in the surrounding Arctic sea by Russia and China.
