President Donald Trump says a permanent Greenland security agreement expands U.S. military rights while leaving Danish sovereignty over the Arctic island intact.
Fox News Digital reported that the United States, Denmark, and Greenland reached the agreement after months of quiet negotiations. The arrangement has no expiration date, the administration said.
The reported terms grant permanent U.S. access, basing, and overflight rights in Greenland. They also let Washington establish additional military installations after consulting Denmark and Greenland, but without requiring their approval.
If carried out as described, the agreement would settle a central security question without transferring sovereignty. Greenland would remain a self-governing territory under Denmark, while the United States gains broad military rights across a vital Arctic position.
The administration also says the terms would remain in force if Greenland eventually became an independent country. That would give American defense planners long-term certainty instead of leaving future access to another round of political bargaining.
Trump celebrated the reported breakthrough in a Friday post on Truth Social. He called it an “Infinite Life” agreement and argued that past presidents had recognized Greenland’s value without securing a permanent answer.
“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. This is an "Infinite Life" Agreement, there is no end!”
Trump said the United States would immediately begin developing a large military presence in suitable parts of Greenland. He added that Washington would work with Greenland’s people on development and construction.
The United States already operates Pituffik Space Base in northern Greenland. Its military-access relationship with the island dates to a 1951 defense agreement, but the new arrangement would go much further.
Secretary of State Marco Rubio called the agreement “a huge win for the United States and the American people.” He said it permanently protects American security interests in the Arctic at no cost to U.S. taxpayers.
An unnamed senior U.S. official made the same financial point. The official said Washington would not spend money merely to obtain the right to expand its military presence.
The administration’s outline bars China, Russia, and other non-NATO countries from placing military bases or troops in Greenland. It also restricts adversaries from investing in sensitive industries that could threaten American security.
Those protected areas include telecommunications systems, undersea cables, ports, and critical minerals. Only the United States and its allies could make investments classed as sensitive under the reported terms.
That provision reaches beyond military construction. Ports, communications networks, and cables can shape who controls access and information long before foreign troops arrive.
The administration also believes a larger American presence could eventually support Trump’s planned Golden Dome missile-defense system. No specific Greenland sites for future construction were identified.
Rubio said Denmark and Greenland share the security concern but lack the money needed to defend the island if threatened. “The United States has the power to do that,” he said.
Representatives from the United States, Denmark, and Greenland began negotiating in February, though the year was not specified. White House adviser Stephen Miller joined officials from the State Department and National Security Council in the talks.
Danish Prime Minister Mette Frederiksen issued a message opposing Trump’s designs on Greenland during the 2026 NATO Leaders Summit in Ankara, Turkey. That came on the Wednesday before Trump announced the reported agreement.
The sharp disagreement makes the outcome more consequential. Trump did not secure U.S. sovereignty over Greenland, but the administration says he obtained the lasting defense rights that drove his national-security campaign.
Several important details remain unavailable. No formal agreement text was provided, and the legal status, enforcement rules, and full consultation process have not been published.
Denmark and Greenland also had not provided responses in the account of the agreement. Their own descriptions of the terms will matter, especially where new installations and sensitive investments are concerned.
But the principle is sound: American security should not depend on wishful thinking about hostile powers. Durable access, clear rights, and firm limits serve the country better.
