Trump Signed a Greenland Deal At the UN and the Terms Have No Expiration Date

Denmark's Mette Frederiksen called Trump's idea of buying Greenland absurd back in August 2019.

Seven years later, she signed her name next to his at the United Nations.

What Denmark handed Washington in that room goes far beyond the one base America already has.

Two New Bases and a Bigger Pituffik

Trump signed the agreement on September 22 in New York alongside Frederiksen and Greenland Prime Minister Jens-Frederik Nielsen.

It clears the way for a major expansion of Pituffik Space Base, the northernmost American military installation on the planet.

Pituffik is the early-warning post that watches for missiles coming over the top of the world.

The deal also creates two new American defense areas.

One is at Narsarsuaq in southern Greenland, a former Cold War airbase.

The other is at Mestersvig on the east coast, currently home to Denmark's famed Sirius Dog Sled Patrol.

The two sites sit roughly 950 miles apart.

Trump did not waste time.

He said the United States will "immediately begin the process of developing a significant military presence in appropriate locations and constructing two very important military bases."

American planes and warships get wide-ranging access to the island and the seas around it.

American submarines can travel Greenland's territorial waters "without restriction except as mutually agreed upon."

The agreement also points toward "establishment of a Golden Dome defense system" to protect NATO territory, Greenland, and North America.

Secretary of State Marco Rubio was all smiles.

"This historic deal is a huge win for the United States and the American people," Rubio said. "Greenland will forever be part of the strategic defense area of North America."

The cost to American taxpayers for the new basing rights is zero.

China and Russia Are Locked Out of the Arctic's Front Door

The deal bars any non-NATO country from setting up military bases or stationing troops in Greenland without consent.

It also slams the door on adversary money flowing into Greenland's phone networks, undersea cables, ports, and critical minerals.

That hits Beijing right where it has been aiming.

Lexington Institute vice president Rebecca Grant wrote that by 2017, Chinese foreign investment in Greenland equaled roughly 11 percent of the island's entire economy.

China even bid on contracts to expand Greenland's airports before Denmark blocked it.

Russia is the other target.

"Russia fires a nuclear weapon from a submarine in the Arctic? It's the job of Pituffik to spot it," Grant wrote.

The agreement has no end date.

It stays in force even if Greenland one day declares independence from Denmark.

America Has Wanted Greenland Since Truman

This is not a new obsession.

In 1946, Harry Truman offered Denmark $100 million in gold for the island.

Denmark said no, but signed the 1951 defense agreement that gave America a foothold there.

At the height of the Cold War, thousands of American troops were spread across 17 bases in Greenland.

Before this deal, that presence had dwindled to about 200 service members.

The new deal amends and builds on that 1951 treaty rather than replacing it.

Greenland's leader sounded like a man who had picked his side.

"Your security is our security, and our security is your security," Nielsen said at the signing.

Frederiksen was more subdued.

"The kingdom of Denmark is in a better place than we were yesterday," she said.

The Greenland Joke Ended at the United Nations

In January 2026, Trump's push for Greenland set off a full-blown diplomatic crisis inside NATO.

He refused to rule out military or economic force, and the foreign policy establishment lost its mind.

The experts warned he was going to blow up the alliance.

Instead, negotiators held three quiet rounds of talks starting in February.

The result is a permanent American security presence on the most important piece of real estate in the Arctic.

The deal still needs approval from the Danish and Greenlandic parliaments, but both governments signed it at the UN in front of the world.

Russia has been rebuilding Soviet-era bases along its Arctic coast, and China has been calling itself a "near-Arctic state."

Trump planted two new American flags in their path without paying a dime for the rights.

Leverage works.
