Now, Washington, Copenhagen and Nuuk have reached a security agreement that could give the United States many of the strategic advantages it has been seeking without formally acquiring the territory.
That distinction matters. Trump has described the agreement as giving the United States “permanent control” of Greenland’s security. Denmark, however, says the arrangement recognises the sovereignty and territorial integrity of the Kingdom of Denmark and Greenlanders’ right to self-determination. The detailed agreement is not yet fully public and is expected to go through parliamentary procedures after signature.
From “Buy Greenland” to a Greenland Deal
Donald Trump’s interest in Greenland is not new. In 2019, during his first presidency, Trump floated the possibility of the United States purchasing Greenland. Denmark rejected the idea, with then-Prime Minister Mette Frederiksen saying Greenland was not for sale. Trump subsequently cancelled a planned visit to Denmark. The issue returned with considerably greater force after his return to office.
In January 2026, the British House of Commons Library documented Trump's intensified demands that Greenland become part of the United States. Trump said America would obtain Greenland “one way or another” and declined to rule out military force. Greenlandic and Danish leaders repeatedly rejected the idea that the territory was available for acquisition. The situation has now taken a different direction.
Reuters reports that the United States, Denmark and Greenland have reached an agreement that would significantly strengthen the American military presence on the island, including permanent access, basing and overflight rights, while restricting non-NATO adversaries from establishing bases or making certain sensitive investments. The central question is therefore no longer simply whether America will acquire Greenland. It is whether Washington can obtain much of the strategic access it wants without acquiring Greenland itself.
The Greenland Crisis Was Also a NATO Crisis
This is what made the Greenland dispute much bigger than a territorial disagreement. Greenland is an autonomous territory within the Kingdom of Denmark. Denmark is a NATO member. The United States is also a NATO member. Consequently, the possibility of Washington using force against territory belonging to another NATO ally created an extraordinary problem for the alliance. The British House of Commons Library noted that an American military action against Denmark to secure Greenland would directly challenge the mutual-defence foundation of NATO.
The Greenland dispute became one of several sources of strain between Washington and European allies during Trump's second term. Reuters reported this week that Trump's confrontational approach towards NATO has contributed to declining trust among some European allies and encouraged several countries to diversify their defence relationships. Greenland was particularly sensitive because it involved the territory of a European NATO ally itself.
That does not mean Greenland alone created the broader transatlantic tensions. Defence spending, Ukraine, trade disputes and disagreements over the future of European security were also major factors. But Greenland brought the sovereignty question unusually close to the centre of the NATO relationship. The new agreement therefore matters not only for Washington and Copenhagen. Denmark's government is now explicitly presenting the emerging arrangement as something that strengthens security in the Arctic and North Atlantic and is “great for NATO and Europe.”
After months of pressure to acquire Greenland, the United States has reached a security agreement with Denmark and Greenland. The emerging arrangement could significantly expand Washington’s military position in the Arctic, but it does not amount to a transfer of Greenlandic sovereignty.

The Greenland question has travelled an extraordinary distance. What began with Donald Trump’s proposal to buy Greenland in 2019 evolved during his second term into demands for American control, threats that the United States would obtain the island “one way or another,” and even refusal to rule out military force.
Why Greenland Matters: Military Geography, Minerals and Energy
The military argument is only one part of Greenland's strategic importance. Greenland covers more than 2.1 million square kilometres, sits between North America and Europe, and occupies a crucial position in the Arctic and North Atlantic. The United States already operates Pituffik Space Base, making the island an important location for American space surveillance and missile-warning capabilities.
But beneath the ice and across Greenland's enormous territory lies another strategic story: natural resources. The European Commission says Greenland holds 25 of the 34 critical raw materials identified by the EU. These resources are increasingly important for advanced manufacturing, defence, electronics and the energy transition. The EU and Greenland already have a strategic partnership on sustainable raw-material value chains. And this interest is not theoretical. In September, the European Commission announced a €200 million EU-Greenland partnership package covering connectivity, sustainable energy and critical raw materials.
There is also energy potential. The European Commission describes Greenland as having significant renewable-energy potential, while noting that new oil and gas exploration licences have been halted. So describing Greenland simply as “oil-rich” would be misleading. Its resource importance is broader: critical minerals, renewable energy potential and other geological resources. This creates a much larger geopolitical picture. Greenland sits at the intersection of military geography, Arctic access, critical minerals, energy and emerging economic competition.
Trump Says “Permanent Control.” What Does the Deal Actually Give America?
This is where caution becomes essential. Trump has presented the agreement in sweeping terms, saying it gives the United States permanent control over Greenland's security and related responsibilities. Reuters reports that his announcement described permanent American access, basing and overflight rights and restrictions on foreign military activity and sensitive investments. But Trump's description should not automatically be treated as the legal meaning of the agreement.
Denmark's official statement is considerably more measured. Prime Minister Mette Frederiksen said the agreement recognises the sovereignty and territorial integrity of the Kingdom of Denmark and the Greenlandic people's right to self-determination. Greenland's Prime Minister Jens-Frederik Nielsen said the agreement recognises Greenland's interests and its place in international cooperation.
There is another important qualification: the detailed legal text has not yet been publicly released, and Denmark says that after signature the agreement must undergo the necessary parliamentary procedures before entering into force. So the facts currently support a distinction: Trump is claiming permanent American security control. The announced agreement, as described by Denmark and available reporting, preserves Danish sovereignty while substantially strengthening the American security position. The precise boundary between those two descriptions will only become clear when the final text is public and implemented.
Did Trump Get Greenland Without Getting Greenland?
That may ultimately be the most useful way to understand this extraordinary episode. The United States does not appear to be acquiring Greenland's territory under the emerging agreement. Denmark's sovereignty remains explicitly recognised, while Greenland's right to self-determination remains part of the framework. At the same time, Washington could gain something strategically significant: long-term military access, greater freedom to develop its presence, and restrictions on rival powers establishing military or sensitive economic positions on the island.
In that sense, the outcome could be considerably different from the original “buy Greenland” proposition while still addressing many of the strategic concerns that Washington has repeatedly cited. And there is a broader lesson. The Greenland dispute began as an extraordinary argument over territory and sovereignty. It has now evolved into a negotiation over access, security, resources and strategic influence. For Europe and NATO, the challenge is whether this new arrangement can repair some of the trust damaged during the confrontation. For Greenland, the central issue remains how its growing strategic importance can translate into security and economic opportunity without undermining its autonomy. And for Washington, the question is simpler: Was Greenland ever really about owning the island or was it ultimately about controlling the strategic space around it? The final agreement may provide the clearest answer yet.
