WASHINGTON — President Donald Trump announced Friday that the United States has reached a landmark security agreement with Denmark and Greenland, granting Washington permanent rights to expand its military presence on the strategically vital Arctic island while blocking adversaries from establishing bases or making sensitive investments there.
The deal, expected to be formally signed next week on the sidelines of the United Nations General Assembly in New York, addresses long-standing American national security concerns in the region without any transfer of territory or cost to U.S. taxpayers.
In a Truth Social post, Trump described the arrangement as an “Infinite Life” agreement that gives the United States “permanent control over security, and all other needs, in Greenland,” completely resolving U.S. concerns. “We 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,” he wrote. He added that the United States would immediately begin developing a larger military presence on the island and that no U.S. adversary could ever establish a base, maintain a military presence, or make sensitive investments without explicit American approval.
Secretary of State Marco Rubio hailed the outcome as a major achievement. “This deal permanently and completely addresses our national security concerns in Greenland,” Rubio said. “Greenland will forever be part of the strategic defense area of North America and exclude any adversary from it and the surrounding area.”
A State Department official confirmed key elements of the agreement: permanent U.S. access, basing, and overflight rights; the ability to build additional military facilities as needed; a ban on non-NATO countries establishing bases or stationing troops; and mechanisms to prevent adversarial investments in sensitive sectors such as critical minerals. The pact is designed to remain in force even if Greenland eventually becomes independent.
Danish Prime Minister Mette Frederiksen and Greenlandic Premier Jens-Frederik Nielsen welcomed the accord, stressing that it strengthens Arctic and North Atlantic security while fully recognizing the sovereignty and territorial integrity of the Kingdom of Denmark and the right of the Greenlandic people to self-determination. “It is a great agreement for Greenland, the Kingdom of Denmark, and the United States,” Frederiksen said. Nielsen called it “joyous” that the deal enhances the security of Greenland, Denmark, the United States, and the broader Western alliance.
The agreement builds on the existing 1951 U.S.-Denmark defense arrangement that already permits American forces in Greenland, including the long-standing Pituffik Space Base. Officials on both sides noted that no territory is being transferred and that Greenland retains the ability to pursue greater self-determination.
Greenland’s location astride emerging Arctic shipping routes and its deposits of rare earth minerals and other resources have made it increasingly important amid rising great-power competition. The new framework ensures that China and Russia cannot gain a military or strategic economic foothold on the island, while enabling the United States to reinforce its defensive posture in the High North—including potential contributions to broader missile-defense efforts.
The deal is expected to undergo necessary parliamentary procedures in Denmark and Greenland before entering into force. It marks a diplomatic resolution after months of heightened discussion over the island’s strategic role and represents a concrete step to lock in American security interests in the Arctic for the long term.
