Greenland Security Deal Heads to Tuesday Signing as Denmark Confirms Terms, Text Still Not Public

Since President Trump announced a Greenland security agreement on Truth Social Friday, September 18, Denmark and Greenland have both confirmed the deal, and the three parties are scheduled to formally sign it Tuesday, September 22, in New York on the sidelines of the U.N. General Assembly.

A signing ceremony, not just an announcement, is now in the works. Danish Foreign Minister Lars Lokke Rasmussen said Saturday, September 19, that "next week could be a good week for Greenland, Denmark, and the USA alike," adding the agreement would strengthen "security in the Arctic and the North Atlantic" while respecting "the Kingdom's red lines," according to ZeroHedge's republication of Epoch Times reporting.

What's actually in it, as far as anyone knows

The full text has not been made public. A State Department official told CBS News the deal guarantees the U.S. permanent access to Greenland and overflight rights, letting the military potentially add more bases beyond Pituffik Space Base, which the U.S. has operated since the 1951 Defense of Greenland Treaty. The same official said the agreement bars non-NATO countries from building military bases on the island and restricts adversary investment there, and stays in force even if Greenland becomes fully independent.

CNN noted it's unclear how far this actually differs from the existing 1951 pact, which already gave Washington broad latitude to operate militarily in Greenland. The text still hasn't been released.

Secretary of State Marco Rubio called it a "huge win," saying Greenland will "forever be part of the strategic defense area of North America" and that the deal "permanently and completely addresses our national security concerns." Trump, on Truth Social, called it an "Infinite Life Agreement" and insisted there will be "NO COST to the United States."

From annexation threats to a signed pact

This deal caps a dramatic reversal in tone. Trump spent early 2026 threatening to buy or forcibly take Greenland, at one point floating tariffs on Denmark and other countries that wouldn't "go along with" a purchase, according to CBS News. His administration didn't rule out military force. That rattled NATO allies and, as CNN reported, drew fierce opposition from Denmark, a treaty ally.

Danish Prime Minister Mette Frederiksen struck a notably warmer tone this time, calling it "an agreement that at the same time recognizes the sovereignty and territorial integrity of the Kingdom and the right of the Greenlandic people to self-determination." Greenlandic Prime Minister Jens-Frederik Nielsen echoed that language almost word for word in his own statement.

The Washington Post described Danish officials as "cautiously optimistic." Nobody in Copenhagen is celebrating a rare-earths bonanza; they're relieved the annexation threat appears to be off the table.

Not everyone in Nuuk is sold

Aaja Chemnitz, who represented Greenland in the Danish parliament for over a decade until this year's election, offered the sharpest pushback, according to Arctic Today. She wrote on Facebook that she doesn't "buy his premise of acute threats in the waters around Greenland. Other than American political threats." Her concern: the deal could hand Washington effective veto power over which foreign investments Greenland accepts, on top of giving the U.S. the upper hand on military security.

If the reported provision barring non-NATO investment is real, Greenland is trading some economic sovereignty for a security guarantee it may not have needed in the first place. Chemnitz argued the better path was strengthening Greenland's own economy and education system rather than more American troops. She said she'd stay skeptical "until the text is public," noting "hope alone is rarely a good strategy."

The Atlantic Council's own strategy task force, in a paper published in May, cautioned that Greenland's mineral wealth "will take a decade or more to translate into meaningful supply" — a reality check on how fast any of this pays off.

The business case Trump is leaning on

Robert Price, CEO of Greenland Energy Company and president of USFM Corporation, told Fox News Digital his companies are drilling around Disko Island for nickel, copper, palladium and cobalt, and plan an exploratory oil well in 2027. He tied the urgency directly to the war-driven disruption of the Strait of Hormuz and to reducing U.S. dependence on Chinese and Russian critical minerals. Price compared the district's potential to Russia's Norilsk region — a claim not yet proven, since exploratory drilling is still underway.

What's unresolved

The signing is scheduled for Tuesday in New York. Until the actual document is released, the specific legal mechanics of "permanent" access, the investment-screening provision, and how this differs from the 1951 treaty remain unverified claims from officials on background, not settled fact.
