The United States, Denmark and Greenland will likely reach a compromise deal that significantly expands the U.S. military and economic footprint in Greenland without formal annexation, though continued U.S. coercive pressure could still destabilize NATO cohesion and trigger a broader transatlantic crisis if ongoing talks break down. Details have emerged over the past week about the content of ongoing trilateral negotiations between Washington, Copenhagen and Nuuk aimed at finding a resolution to the dispute triggered by U.S. President Donald Trump's repeated demands to acquire Greenland. A May 12 report from the BBC said U.S. officials were pushing for three new military bases in southern Greenland focused on surveilling Russian and Chinese maritime activity in the GIUK Gap, the strategic stretch of the northern Atlantic between Greenland, Iceland and the United Kingdom. One of the new bases would likely be located at the site of the former U.S. base in Narsarsuaq, while the others would likely be in areas with existing infrastructure, such as airfields or ports, to reduce upgrade costs. U.S. negotiators have reportedly asked for the bases to be formally designated as U.S. sovereign territory, though no official agreement has been reached on the matter. Meanwhile, a May 18 investigation by The New York Times revealed that Washington is seeking several guarantees, including the right for U.S. troops to maintain an indefinite presence on Greenland, even if it gains independence from Denmark; effective veto power over major foreign investments to limit Russian and Chinese influence; and a framework for collaboration concerning the island's oil, uranium and critical mineral resources. According to the report, the Pentagon has also recently sent a Marine Corps officer to Narsarsuaq to inspect the World War II-era airport, the harbor and potential housing sites for U.S. troops. 

• A working group on Greenland's future was established in January and has reportedly met at least five times in Washington since then. The U.S. side is led by Michael Needham, a top adviser to Secretary of State Marco Rubio, and is typically accompanied by one or two officials from the State Department or the National Security Council. The chief Danish negotiator is Jeppe Tranholm, the permanent state secretary of foreign affairs, alongside Jesper Moller Sorensen, Denmark's ambassador to the United States. Jacob Isbosethsen, the top Greenlandic diplomat in Washington, represents Nuuk.
• U.S. Ambassador to Denmark Kenneth Howery and U.S. special envoy to Greenland Jeff Landry traveled to Nuuk between May 18 and May 20, where they met with Greenlandic Prime Minister Jens-Frederik Nielsen and attended the Future Greenland conference. Landry said his meetings with small and large business owners "revealed broad interest in expanding ties" with the United States. Nielsen described the meeting as "constructive" but said it "showed no indications" that Trump's stated wish to acquire Greenland had changed. Nielsen also indicated on May 12 that the existing arrangement covering the U.S. Pituffik Space Base in northern Greenland could serve as a template for any new U.S. bases, though other arrangements remained on the table.
• On May 21, the United States also inaugurated a new consulate building in Nuuk, its first dedicated facility in Greenland since the 1950s, with several hundred protesters gathering outside to demonstrate against recent U.S. pressure to gain control of the island.

Trump's push to acquire Greenland triggered a crisis that threatened transatlantic trade and security relations before trilateral negotiations partially defused tensions, but the end of the Iran war could bring the administration's focus back to the issue, risking fresh escalation. The Trump administration has repeatedly flagged Greenland's centrality to U.S. Arctic strategy and homeland security, citing the island's position at the heart of the North American Arctic shield and astride the GIUK Gap, through which Russian submarines and aircraft must transit to reach the Atlantic. The administration has also highlighted Greenland's untapped deposits of rare earths, uranium and other critical minerals, as well as the need to limit China's expanding presence in the Arctic, especially as thawing ice from climate change opens up new commercial and military maritime routes. Until recently, these interests were managed through a relatively stable framework rooted in Danish sovereignty over the island and NATO defense arrangements. This framework included the permanent U.S. presence at Pituffik Space Base (which has hosted U.S. early-warning and surveillance capabilities since the Cold War), as well as close coordination between Washington, Nuuk and Copenhagen to restrict Chinese commercial inroads. Discussions were also underway on increasing NATO's presence around the island, deeper defense integration and even a potential future Compact of Free Association with a more autonomous Greenland. However, tensions escalated in 2025 after Trump made public remarks about annexing the island and refused to rule out the use of force or economic coercion. The crisis peaked in January 2026 after Trump threatened to impose additional tariffs on eight European countries that had publicly opposed U.S. demands and explored a limited military deployment to the island. Later that month, Greenland and Denmark agreed to enter trilateral negotiations with Washington, partially defusing the dispute. With Trump's attention having recently shifted toward the Iran war, the trilateral track has been able to narrow the scope of U.S. demands and explore possible compromise frameworks. But a wind-down of the Middle East conflict could quickly bring Greenland back to the top of Trump's agenda and reignite tensions, if talks have not yielded tangible progress by then.

• Greenland is an autonomous territory within the Kingdom of Denmark, currently governed under the 2009 Act on Greenland Self-Government. Denmark remains responsible for the island's defense, foreign policy and monetary system. Under the act, Greenland could become independent following a decision by the Greenlandic Parliament, then a national referendum and negotiations with the Danish government. Greenland remains heavily dependent on Danish subsidies to fund public services, making economic self-sufficiency the primary constraint on independence. Under existing defense agreements, the United States operates Greenland's only military base at Pituffik.

Faced with mounting geopolitical and domestic pressures, the Trump administration is most likely to pursue a negotiated compromise with Denmark and Greenland that expands U.S. strategic access without requiring formal sovereignty over the island. The ongoing talks are most likely to result in the Trump administration softening or deferring some of its demands to secure a compromise agreement that would enable it to take home a win without triggering a costly escalation with the European Union. Such a compromise would most likely take the shape of a modernized version of the 1951 Defense of Greenland Agreement, granting the United States expanded military access — likely two or three new bases in southern Greenland, a deepwater port and a rotational Special Operations presence — under updated U.S.-Denmark-Greenland frameworks, rather than as sovereign U.S. territory. Renewable, multi-decade basing rights might replace controversial demands for a guarantee of an indefinite military presence on the island, while a joint screening mechanism could give Washington a formal role in vetting major foreign investments, effectively granting de facto veto power over Russian- or Chinese-linked deals. Resource cooperation could also grant U.S. companies preferential access to Greenland's critical minerals. Such a compromise would enable the United States to secure expanded access to the island and limit Russian and Chinese influence. Simultaneously, Denmark would preserve formal sovereignty, and Greenland would secure new investment while avoiding a formal handover of its territory. The European Union would also benefit by averting both a NATO crisis and renewed trade escalation with Washington. This outcome will become increasingly likely the longer the Iran war drags on and the more Trump's attention is pulled elsewhere, such as possible military action in Cuba or domestic political pressures ahead of the November U.S. midterm elections. Under these conditions, the administration will likely have less appetite to force a maximalist outcome on the Greenland dispute and be more inclined to secure a partial win or let the issue sit. However, that calculus could change at any time, and a pause or resolution in those competing crises could shift the Trump administration's focus back to Greenland and revive U.S. pressure for a more far-reaching deal. 

• The 1951 defense agreement, revised in 2004, already grants Washington substantial latitude within Greenland's designated defense areas, allowing it to operate there indefinitely and to develop military infrastructure, provided it keeps Copenhagen and Nuuk informed. It also allows the United States to establish new defense areas, though doing so triggers a consultation requirement that Denmark and Greenland could contest. Danish and Greenlandic negotiators initially argued that the pact gave the United States such extensive freedom of action that taking over the island was unnecessary. On this reading, Washington could meaningfully expand its presence without striking a fundamentally new deal.
• Under the current framework, the United States already holds considerable sway over major investment and infrastructure decisions involving Greenland. Over the past decade, Chinese firms have repeatedly sought to expand into Greenlandic mineral and infrastructure projects, but most efforts have been blocked through U.S.-Danish coordination or local environmental rules. The clearest example came in 2018, when a Chinese state company emerged as a frontrunner to build several airports, including at the tourist hub of Ilulissat, before U.S. pressure prompted Denmark to intervene and Greenland awarded the contract to a Danish firm instead.
• Greenlandic officials have signaled openness to a larger U.S. economic footprint and military presence on the island but have drawn firm red lines elsewhere. Nielsen has repeatedly ruled out ceding any sovereignty and, while welcoming greater U.S. involvement in Greenland's critical resources, insisted that its strict environmental rules would remain in place. Officials also resist allowing Washington to dictate investment decisions, arguing that it would violate Greenlandic sovereignty and foreclose any prospect of real future independence.

Even if it does not formally annex Greenland, the United States' sustained pressure could gradually establish de facto American control over the island's security, economy and strategic future, while weakening Danish influence and straining transatlantic relations. In a less likely scenario, under sustained U.S. pressure, Copenhagen and Nuuk could ultimately concede on more controversial issues, such as an indefinite presence guarantee, a formal investment veto or even some form of sovereign-territory designation for U.S. bases on the island. Such concessions would entrench U.S. influence over Greenland's security and resources. Sovereign base enclaves could set a precedent for later expansion — first to surrounding infrastructure and mining areas, then potentially to wider stretches of territory — while U.S. economic transfers progressively supplant Danish subsidies and shift Greenland's dependency toward Washington. Meanwhile, an indefinite U.S. presence guarantee would make Greenland's eventual independence from Denmark not merely compatible with but potentially conducive to future U.S. annexation. Absent a deal, Washington could instead unilaterally expand its footprint under a permissive reinterpretation of existing agreements, deploying additional air-defense assets, intelligence platforms and rotational forces while presenting the move as a national security priority. In either case, Copenhagen and Nuuk would likely resist but may eventually tolerate the new status quo to avoid an escalation of military, economic and political tensions. This would ultimately enable the United States to secure de facto control over the island's security environment and steadily erode Denmark's relevance, without having to mount a formal sovereignty challenge that would trigger a transatlantic crisis. Such an outcome would limit the immediate political and diplomatic backlash, contain U.S.-European tensions and avert a near-term NATO crisis. However, it would still risk significant pushback from Greenlandic authorities and civil society, and deepen European perceptions of the United States as an increasingly unreliable ally, reinforcing momentum toward rearmament and strategic autonomy in Europe.

• The 2004 Igaliku Agreement — which updated the original 1951 framework — requires the United States to consult Denmark and Greenland before making any "significant changes" to its military operations or facilities on the island. Copenhagen interprets this consultation requirement as conferring an effective veto over U.S. moves, but Washington could treat it as a procedural formality that imposes no real constraint. This divergence in interpretation would give the United States a degree of legal and political cover to enlarge its footprint, while leaving Denmark and Greenland with little practical recourse short of escalation.

If, however, negotiations break down, the Trump administration could revert to economic and diplomatic coercion, reopening the prospect of a spiraling transatlantic trade war and a serious fracturing of NATO, but a U.S. military occupation of the island would remain highly unlikely. If the negotiations collapse, Washington will likely revive its tariff threats against EU countries (or the bloc as a whole) over Greenland. The Trump administration could, for example, use Section 232 or Section 301 tariffs, potentially alongside non-tariff levers such as export controls, restrictions on European firms' access to U.S. procurement, and heightened regulatory and antitrust scrutiny. Such moves would almost certainly collapse the already fragile EU-U.S. tariff framework agreed in 2025, prompting the European Union to reinstate the roughly 93 billion euro retaliation package it had suspended during negotiations. In a more extreme scenario, the bloc could also activate its Anti-Coercion Instrument, enabling countermeasures spanning tariffs, services, investment and public procurement access for U.S. companies. These steps would invite further U.S. retaliation, triggering a tit-for-tat spiral that would impose high economic costs on both sides and narrow the scope for any near-term de-escalation. The diplomatic and security fallout would further strain NATO cohesion at a moment of acute confrontation with Russia, which would likely seize the opportunity to intensify its hybrid activity and military signaling in the Baltic and Arctic. It would also fuel additional U.S. troop withdrawals from Europe and attacks by the Trump administration on the alliance's Article 5 guarantees, while accelerating European rearmament and strategic autonomy efforts. However, an outright U.S. move to occupy the Green remains highly unlikely, given the enormous strategic, legal and political costs it would involve and the absence of any real need for it when Washington can secure most of its objectives through less drastic means.
