Trump says US has reached an agreement to take permanent control of Greenland’s security

President Donald Trump has announced an agreement with Greenland, granting the U.S. permanent control over the Arctic island’s security.

The agreement stipulates that U.S. adversaries such as Russia and China will require Trump's approval to engage with Greenland militarily and economically.

Despite opposition from Greenlanders, European allies, and a majority of Americans, Trump has declared the agreement as a significant achievement for national security.

President Donald Trump has announced an agreement with Greenland , in which the U.S. will take permanent control of the Arctic island's security.

"I am pleased to announce that the United States of America has entered into an Agreement with The Kingdom of Denmark, and Greenland, that gives the United States permanent control over security, and all other needs, in Greenland, completely addressing ALL of our many U.S. concerns," Trump wrote on Truth Social Friday evening.

The president has eyed Greenland since before he returned to the White House in January 2025, arguing that the U.S. needed to control the semi-autonomous Danish territory for national security purposes.

Trump said that the agreement means the U.S. "will FOREVER have the complete ability to do what is necessary in Greenland in order to secure and defend the security of Greenland, and the United States of America."

It's unclear what exactly is in the agreement Trump claims to have struck with Denmark and Greenland, but he did highlight one major point — U.S. adversaries such as Russia and China will need his approval to work with Greenland militarily and economically.

"From now on, no U.S. adversary can EVER have a base in Greenland, have a military presence in Greenland, or make sensitive investments in Greenland, without our express written approval," Trump said.

"It's so strategic. Right now, Greenland is covered with Russian and Chinese ships all over the place," Trump claimed during a press gaggle aboard Air Force One in January. "We need Greenland from the standpoint of national security — and Denmark is not going to be able to do it."

Trump boasted about his role in the new agreement with Greenland that he said would be "cherished by the American People."

"For over 100 years, Presidents have known the strategic importance of Greenland, but NONE of them were able to do anything about it. I am proud to be the President that permanently and conclusively addressed this very important situation," he wrote on Truth Social.

"We will immediately begin the process of developing a large Military presence in the appropriate part of Greenland, of which there are many. We will work with the people of Greenland in its development and construction," he added.

Since Trump began pushing to acquire Greenland, he has been met with opposition , not just from the people of the Arctic island and Denmark, but also from America's European allies.

"Greenland belongs to its people. It is for Denmark and Greenland, and them only, to decide on matters concerning Denmark and Greenland," a joint statement from seven European leaders read.

In the January 6 statement, leaders from France, Germany, the United Kingdom and other U.S. allies said, "We and many other Allies have increased our presence, activities and investments, tokeep the Arctic safe and to deter adversaries."

They said that since Denmark is a part of NATO, "security in the Arctic must therefore be achieved collectively...by upholding the principles of the UN Charter, including sovereignty, territorial integrity and the inviolability of borders."

Days later, Trump threatened to impose a 10 percent tariff on imports from European allies, several of which were part of the earlier joint statement, "until such time as a Deal is reached for the Complete and Total purchase of Greenland."

Trump quickly backed down from his tariff threats , claiming to have "formed the framework of a future deal with respect to Greenland" with NATO chief Mark Rutte .

Even with the new agreement between government officials, it is doubtful that Trump will sway those in Greenland opposed to American intervention.

The day Trump threatened tariffs against European nations if he did not strike a deal to acquire Greenland, protesters in Nuuk held Greenlandic flags and a banner that read "Make America Go Away" and "We Are Not Property!"

"I think he should mind his own business," Greenlander Lars Vintner, a heating engineer, told the Associated Press in January.

"What's he going to do with Greenland? He speaks of Russians and Chinese and everything in Greenlandic waters or in our country," he said. "Every summer we go sailing and we go hunting and I never saw Russian or Chinese ships here in Greenland."

A majority of Americans are also not sold on the idea of gaining control of Greenland.

Fifty-eight percent of Americans oppose a U.S. takeover of the Arctic island while 21 percent favor it and 20 percent are unsure, according to a Pew Research Center poll from January.
