It has had bases there since the Second World War and has the largest military in the alliance. The 1951 Greenland Defense Agreement allowed the United States to keep its military bases in Greenland, and to establish new bases or "defense areas" if deemed necessary by NATO. The U.S. military could freely use and move between these defense areas, but was not to infringe upon Danish sovereignty in Greenland. The treaty gave the United States permanent jurisdiction over the defense areas of Thule, Sondrestrom and Narsarsuaq. As of 2025, the only U.S. military base in Greenland is

(formerly Thule Air Base). The 2004 Igaliku Agreement stated that Thule Air Base was the only U.S. defense area in Greenland and that the U.S. must inform Denmark and Greenland of any proposed changes. Thus, the U.S. cannot increase its military presence without consent from Denmark and Greenland.

Economy

Greenland's annual GDP was $3 billion, 0.007% that of the United States. Its working-age population is estimated to decline by 16% by 2040. Denmark is by far Greenland's largest trade partner, receiving 55% of the island's exports and providing 63% of imports. it subsidizes Greenland with billion annually, up from billion in 2009. The island's largest private industry is fishing. Covering an area of 2,166,086 km2, it has vast natural resources, including uranium,

mine closed in 2024 after bankruptcy. Javier Blas of Bloomberg wrote in 2025 that "hyperbole around Greenland and commodities has a 50-year long history", noting that the island had never produced any petroleum and the attempt to mine iron ore ended in bankruptcy. A majority of possible mineral sites are north of the Arctic Circle; those south of the circle are mostly small, with Tanbreez among the exceptions. the United States only imported $190 million in rare earths; if prices rose, they could be obtained more easily from American and other deposits than from Greenland. Blas urged the United States to focus on the African copperbelt and elsewhere as more important. "Investing in Greenland is not for the faint of heart", CEO Brian Hanrahan of Lumina said, stating that the anorthosite mine was more complex than any of the 270 worldwide sites he oversaw at another job. A 2014 report stated that replacing the Danish subsidy would require 24 large projects each costing billion, one opening every two years. As no investors existed for such projects, the report by 13 scholars said that Greenland would remain dependent on the subsidy for at least 25 years to maintain its welfare system. Minik Thorleif Rosing, one of the authors, in 2025 said that the situation had not changed: "Even if you had an unrealistically high rate of development of mineral resources, it would be unlikely to replace more than half the annual block grant from Denmark in any near future".

Russia is much more capable of Arctic land combat than the United States, and Greenland may be vulnerable to invasion.

Post-War efforts to repatriate U.S. forces

At the end of the war, Denmark expected U.S. forces to exit Greenland and was taken by surprise when the United States indicated it had no intention of leaving. Over the next several years, Danish officials attempted, unsuccessfully, to convince the United States to leave the island. According to Jeroen van Dongen, a period of tension between the two countries followed as, despite its desires, "Denmark was clearly not in a position to force the USA to leave Greenland" nor did it have any means at its disposal to deny the U.S. access to the territory. By spring 1948 Denmark gave up on persuading the Americans to leave. Part of why the country joined NATO, Trade Minister

made the $100 million offer on December 14, 1946, in a memorandum delivered to Danish foreign minister Gustav Rasmussen when he visited the United States. The memorandum described the American position on what to do about the informal 1941 agreement made in 1941 by Kauffmann to station United States forces on Greenland. It suggested three alternatives: Two variations on the 1941 agreement—A 99-year lease on the existing American bases there, or the United States wholly taking over the defense of the island—or the purchase of Greenland. The United States preferred to purchase and believed that doing so was better for Denmark, as it would prevent criticism of American bases on Danish soil and save Denmark the cost of supporting Greenland. The American told the Dane that a sale "would be the most clean-cut and satisfactory". "Our needs ... seemed to come as a shock to Rasmussen", Byrnes said. The memorandum indeed surprised the Dane; rumors at the time stated that the United States wanted to purchase Greenland, but the Danish government's position was that the United States would withdraw its troops, based upon language in the 1941 Kauffmann agreement that it remained in force "until agreement has been reached that current threats to the peace and security of the American continent have ended". The Danish government understood that the threats were the world war; it did not know that the U.S. understood this to include postwar threats from the

as well. Known as "Article X" of the Kauffmann agreement, the clause established that both sides would have to agree to ending it. Rasmussen declined all three options, and returned to Denmark. He told United States ambassador Josiah Marvel, " ile we owe much to America I do not feel that we owe them the whole island of Greenland". The American offer surprised Rasmussen because of duplicity by Kauffmann, who with a friend at the United States Department of State advocated for an American presence in Greenland while not fully informing the Danish government. Kauffmann had minimized in his reports the importance of proposals of a takeover or purchase in the U.S. House of Representatives, saying that the idea was considered ridiculous by the U.S. government, when in fact it was not. He had also not conveyed important parts of a 1945 American proposal to keep its bases on the island after the war. Rasmussen visited Washington in 1946 expecting to annul the 1941 agreement, not understanding because of Kauffmann's duplicity why nothing had happened with the Danish government's previous overtures in that regard.

By offering to purchase Greenland, the United States told Denmark that it was not likely to ever leave. Denmark would not fully understand for another decade the island's strategic importance to the United States. The Danish government's own outlook on national security was more parochial, and did not extend to viewing Greenland as a part of that.

, the new government of Hans Hedtoft continued and expanded Kauffmann's strategy of duplicity. To the Danish public, it maintained that the United States would withdraw from Greenland as expected. To the United States the Hedtoft government stated that its own private position was that the American presence would remain. Its own private position was to persuade the United States to withdraw. Kauffmann likewise continued with his own personal agenda. The Danish government was not duplicitous on one point: It was not going to outright cede Greenland to a foreign power. Marvel told Rasmussen that he should not do anything that would lead to the disclosure of anything that had transpired in Rasmussen's meeting with Byrnes. The Danish government kept the American interest secret from the public, as part of its own strategy. The 1947 offer was classified until the 1970s, and ''

Cold War and 1955 proposal

A scholar wrote in 1950 that, despite official denials of the rumors of an American purchase, because of Greenland's large expense to Denmark and strategic importance, "the potential sale of the island to the United States remains a distinct possibility". Postwar Denmark was not able to defend Greenland, an ice-covered island 50 times larger than itself. In April 1951 Denmark and the United States signed the Greenland Defense Agreement. Replacing the 1941 agreement, it allows the latter country to keep its military bases in Greenland, and to establish new bases or "defense areas" if deemed necessary by NATO. The American military can freely use and move between these defense areas, but cannot infringe upon Danish sovereignty in Greenland. The agreement remains in force as long as the NATO treaty does. Denmark recognized that without the agreement Greenland would become closer to the United States anyway, whether as a nominally independent country or with a

that the Danes were "very cooperative in allowing the United States quite a free hand in Greenland". A Danish scholar later wrote that his country's sovereignty over the island during the Cold War was fictional, with the United States holding ''de facto'' sovereignty. The BBC wrote that the 1951 agreement "in effect, gave the US whatever it wanted". In 1955 the Joint Chiefs nonetheless proposed to Eisenhower that the nation again try to purchase Greenland, writing that "sovereignty provides the firmest basis of assuring that a territory and its resources will be available for military use when needed. United States sovereignty over Greenland would remove any doubt as to the unconditional availability of bases". Circa 1953 in Operation Blue Jay the United States built

He said that Greenlanders do not want to sell to the United States but want to cooperate as an equal partner, suggesting that Trump visit the island instead of Denmark to negotiate. While a majority of Greenlanders prefer Denmark to the United States, most prefer the latter to China. Another Greenlander hoped that Trump's interest would cause Denmark to "wake up and show Greenland some respect. A lot of Danes think everyone here is just a drunk Inuit. But now that America wants to buy us, maybe they can see there is much of value here". A third said that "for hundreds of years anesearned many, many billions of kroner from Greenland" while neglecting Greenlanders, and hoped that the American attention would give them more power when negotiating with Denmark. Krarup said that Greenlanders were also angry at Denmark for discussing Greenland without them. While Trump needed to "change isattitude", Krarup hoped that the president's interest would change the island's political situation. Among Greenlandic politicians,

encouraged Western mining investment in Greenland. In 2024, American and Danish officials repeatedly told geologist Barnes's company Tanbreez Mining, developer of the island's largest rare-earths deposit, not to sell the project to Chinese developers. Tanbreez sold the project to Critical Metals of the United States, reportedly for much less than what the Chinese offered. The U.S. pressure is akin to similar American efforts to block Chinese influence in Africa's copperbelt. A week before the Trump's re-election in November 2024, Nick Solheim of American Moment, a group preparing for the transition, said that the proposal had been serious. He reportedly cited the

, implying that the government would encourage American settlement of the island. Shortly after the election, Trump ally Representative Mike Collins posted a picture of Greenland in an electoral-college map as voting Republican in "Project 2029", suggesting Trump would make another bid to purchase Greenland during his second term. "Buying Greenland" appeared on a list of foreign policy goals that the incoming administration prepared after the election, and the transition team began discussing business opportunities in Greenland with private industry, including Critical Metals. Gad said that Greenland had discussed their relationship with the two previous American administrations and was aware that "the US will never leave". On December 22, 2024, Trump posted to

appeared to rebuke Trump's offers of owning Greenland, when he stated, "We are all united and each of us committed for the kingdom of Denmark, from the Danish minority in South Schleswig and all the way to Greenland. We belong together". The royal household also ordered the changing of the Royal Arms of Denmark to include Greenland more significantly in the arms. After Trump's Christmas message on Greenland, Greenlandic minister of finance Erik Jensen invited the president-elect to the island (as Siumut chairman, and not on behalf of the government). On 7 January, Donald Trump Jr. arrived in Greenland, but did not meet with Jensen or the Greenlandic government. His guide was Jørgen Boassen, a pro-Trump islander who intends to run in the April 2025 election on a pro-United States platform, although he also stated his opposition to American acquisition of Greenland.

On 14 January, the Trump-affiliated Nelk Boys also visited Godthåb, handing out dollar bills to locals. Frederiksen's priority is maintaining good relations with the Americans, because of the "Greenland map" barter that has been vital to her country's security for 80 years, and because the United States is Denmark's largest trading partner. She requested an audience with Trump. Her government privately reiterated to Trump aides that the island is not for sale, but that it will discuss increasing the United States military presence or any other request.

Opposition MP Rasmus Jarlov criticized her stance that "Greenland belongs to the Greenlanders" and had control over its future, saying that Frederiksen should have more emphatically stated that Denmark opposed U.S. annexation of Greenland. All left parties in the Danish parliament support Greenlandic independence, while the right is divided. Denouncing "Greenlandic fantasists", Morten Messerschmidt, Danish People's Party leader, said Greenlanders would prefer Denmark's social programs to those of the United States: "Greenland will never gain independence. We might as well say that. Greenland will never, ever get independence", he said, adding that Trump would have to negotiate with Denmark, not Greenland.

said that if Trump offered more money than the current Danish subsidy "I can easily imagine that a majority of the population will declare independence". Greenlandic cabinet minister Naaja Nathanielsen said that her government had for years sought more cooperation with the United States or European Union, and that she rarely spoke to Danish media about her island's natural resources, the forced IUD case, or separation of Greenlandic children and parents in Denmark. Her island would use the great Danish and worldwide attention from Trump's interest to settle the scandals, she said. Reiterating that "We are not Danes, nor Americans", Nathanielsen asked for more American mining and infrastructure investment in a ''Washington Post'' op-ed, stating that Canadian and British companies held most licenses. Gad said that Denmark might now be willing to continue subsidizing Greenland for some time after independence. On January 9, 2025, Trump wrote "The people of Greenland would love to become n American state Denmark maybe doesn't like it. But then we can't be too happy with Denmark". While stating his opposition to joining the United States, Broberg said that Trump's interest in Greenland had confirmed the island's importance, and that other nations could help it become independent. Many Danish professionals on the island did not speak Greenlandic, he said, and that an independent Greenland would teach English instead of Danish: "Then it will not matter so much whether it is an American or an Englishman or a third person who speaks English who is going to be a doctor or a teacher. Then you will actually be able to communicate with each other". On 11 January leaders of all five parties in

have reacted negatively to the acquisition wishes of the Trump administration. Jacques Hartmann of Dundee University Law School wrote that even if the Danish parliament voted against Greenlandic independence, Denmark could not stop secession because of the island's right to unilaterally declare independence, which the United States would likely recognize. Greenlandic Premier Egede canceled a planned audience with Frederik X, scheduled to coincide with the date of Trump Jr.'s visit, in what officials attributed to a scheduling conflict but the ''Copenhagen Post'' noted was "not a normal occurrence". The meeting with the king was shortly after rescheduled and took place, four hours later than initially planned; royal historian Sebastian Olden-Jørgensen said that Egede rescheduled the meeting to prove that he did not "bow to Denmark". At a previously scheduled joint press conference on 10 January, Frederiksen and Egede said that the incoming Trump administration had not contacted either. "The status quo is not an option", the latter said: "Greenland is for the Greenlandic people. We do not want to be Danish, we do not want to be American. We want to be Greenlandic", but he understood America's strategic interest in his island. Egede said he wanted to be able to speak to a foreign leader without a Danish ambassador present.

wrote that Egede seemed overwhelmed, regretting the sudden immense global interest Trump's interest had caused in him and his island. Frederiksen described American interest in Greenland as positive, by causing the island and her country to reevaluate each other. She said that Greenlandic desire for independence was "legitimate and understandable" but that she wanted the island to remain within the kingdom. Gad stated that Frederiksen—unlike previous Danish governments—was not completely against a Danish COFA with Greenland. She might decide that, given the Trump discussion, a looser relationship with the island was better than completely losing Denmark's Arctic role, the scholar said.

said "It is incredibly important that we do not allow Russian and Chinese influence to grow". Admiral James Stavridis (USN, Ret.) said Greenland "is an immensely valuable piece of real estate" because of its strategic location, natural resources, and potential for post climate-change agriculture. Since he did not expect American acquisition of the island, and advised against independence, the former SACEUR proposed that the United States improve the island's infrastructure, police, military, and tourism. Gad, the author of ''Greenland in Arctic Security'', said that while the GIUK gap and Pituffik are important for American national security, "neither the US nor Danish and Greenlandic authorities have so far found anything that warrants further military buildup in Greenland". On March 4, 2025, Trump gave a speech before the United States Congress where he declared: "One way or the other, we’re going to get" Greenland. In his March 13, 2025 meeting with NATO Sec. Gen. Rutte, Trump suggested that he would be working with NATO when annexing Greenland, which he said he thought would happen. Rutte responded saying that he wanted to "leave that [issue] outside...

=Make Greenland Great Again Act

= On January 13, 2025, legislation was introduced in the U.S. House of Representatives by Rep. Andy Ogles to authorize the U.S. government to acquire Greenland on behalf of the United States, granting to Congress a 60-day review period prior to integration of Greenlandic territory into the United States. As of the date of introduction, the bill had 12 co-sponsors and had been referred to the United States House Committee on Foreign Affairs for review.


=Red, White, and Blueland Act of 2025

= On 10 February 2025, Representative Buddy Carter introduced a legislation which would rename Greenland to "Red, White, and Blueland" and allow US President Donald Trump to "purchase or otherwise acquire" Greenland. Carter further stated, "When our Negotiator-in-Chief signs this historic agreement, we will proudly welcome the people of what is now Greenland to join the freest nation in history. President Trump has rightly identified this purchase as a national security priority." The legislation gives the office of the United States Secretary of the Interior, Secretary of the Interior six months after its passage to ensure that federal documents are updated to reflect the name change.


Purchase price estimates

*In August 2019, ''The Washington Post'' estimated a purchase price of Greenland between $200 million and $1.7 trillion, with a middle estimate of $42.6 billion. The lower figure was based on an inflation- and size-adjusted valuation of what the United States paid for Alaska, and the higher figure based on a price-to-earnings ratio of 847, which the newspaper said might be justified based on future valuations of its mineral deposits, and the possibility that it might become a residential destination due to both the Climate change in Greenland#Adaptation, effects of climate change and becoming a United States territory. *The ''Financial Times''s FT Alphaville estimated a $1.1 trillion price for the territory. Its sum-of-the-parts analysis valued potential oil fields at $300 billion to $400 billion, rare-earth minerals at $500 billion to $700 billion, and real estate at $200 billion to $220 billion. The newspaper wrote that the US has "a history of accretive land acquisitions", with a 7.1% internal rate of return for the Louisiana Purchase, 7.4% for Manhattan, and 9.0% for Alaska. *24/7 Wall Street estimated a purchase price for Greenland of $533 billion, using Wyoming as a comparables, comparable. "If the United States wants it for the strategic value of its property, both on land and offshore, and to project military power, the answer is that a value of $500 billion is not overly rich", 24/7 Wall Street concluded. *FT Alphaville reiterated its $1.1 trillion estimate in 2025. *''The Economist'' said of its $50 billion valuation using discounted cash flows—one twentieth of annual US defense spending—or about $1 million to each resident, not including its value to American national security: "Given the territory's riches and importance, America could probably make every Greenlander a multimillionaire and still benefit enormously from the purchase". *Noel Maurer of George Washington University estimated that royalties and mining tax revenues would be worth $16 to $20 billion to the U.S. federal government, net of the cost of continuing the existing Danish subsidy to Greenland. He discounted future mining revenues for the risk that they might not materialize. Maurer also estimated an additional strategic value between $12 and $24 billion, based on past U.S. offers for similar territories, for a total value between $29 billion and $45 billion, or $518,000 and $804,000 per Greenlandic citizen. *David R. Barker estimated a $12.5 billion to $77 billion purchase price, noting that if Greenland benefited national security, "its value increases with the size of the U.S. economy". *Nikola Swann of credit consultant SwissThink stated that the island's mineral wealth was more important because of the existing American military presence. Barker thought the ''Financial Times'' estimate was too high because the government and private industry would share the benefits of drilling and mining rights. Swann said that the importance of pharmaceuticals to the Danish economy strengthened Trump's tariffs threat. Several estimates agreed that buying Greenland would be "the deal of the century".


Governance proposals

Several proposals have been advanced for governance of Greenland in the event of its acquisition by the United States. Former U.S. National Security Advisor Robert O’Brien suggested that the United States could award Greenland to
Alaska Alaska ( ) is a non-contiguous U.S. state on the northwest extremity of North America. Part of the Western United States region, it is one of the two non-contiguous U.S. states, alongside Hawaii. Alaska is also considered to be the north ...
, noting that "the native people in Greenland are very closely related to the people of Alaska". A report issued by Audubon found that harmonizing Alaska's common law legal system with the Danish Civil law (legal system), civil law used in Greenland would present issues, and that "indigenous populations could face challenges related to rights, cultural preservation, and social integration". The report also found that merging the two countries would offer "several advantages for the United States, spanning economic, strategic, and environmental domains". Barry Scott Zellen, a scholar of Arctic strategy at the United States Coast Guard Academy, suggested Greenland could become an Territories of the United States, organized and unincorporated territory of the United States but with a clear pathway to eventual admission as a constituent state "not unlike that which Alaska followed". According to Zellen, "Greenlandic Inuit, who suffer from a long legacy of neglect and whose colonial experience, despite recent gains in autonomy, has not been entirely positive, may indeed stand to benefit in many ways" from this arrangement. In November 2024, Gray proposed that an independent Greenland sign a COFA with the United States which would guarantee American economic and military assistance, describing it as "the deal of the century". Trump officials reportedly discussed creating a COFA and Greenlanders are aware of the proposal, in addition to their own longstanding internal discussions of seeking a COFA with Denmark or the United States. Writing in The Volokh Conspiracy, Josh Blackman suggested—in a post-acquisition scenario—the United States Congress could place Greenland within the United States Court of Appeals for the Fifth Circuit, fifth judicial circuit whose judges, he opined, might be more friendly to permitting resource extraction. Trevor Filseth of ''The National Interest'' wrote that in addition to promising that "life in Greenland will remain the same or improve under the American flag" as an autonomous territory, Trump should commit to a subsidy larger than Denmark's and exemption from the Jones Act.


Coercive annexation


U.S. plans and capabilities

During a 8 January 2025 press conference at The Pentagon, Sabrina Singh declined to answer the question of a reporter who asked "Are there plans to take Greenland by force if ordered to do so?" saying she would defer comments on the matter to "the incoming administration". Asked on 14 January by Senator Mazie Hirono about the potential use of military force to integrate Greenland into the United States, Pete Hegseth—then presumptive nominee for United States Secretary of Defense—stated he would not provide details in a public forum. In January 2025, then-Vice President-elect of the United States, Vice President-elect JD Vance repeatedly stated that controlling Greenland is critical for U.S. national security and said that there's "a deal to be made in Greenland". Following a 15 January telephone call with Trump, Frederiksen confirmed the United States' interest in acquisition of Greenland and its commitment to apply punitive, economic sanctions against Denmark until it acquiesced to the transfer of the territory. In a meeting with the parliamentary committee on foreign policy, Frederiksen said the nation was in "a serious situation", that "unfortunately, we could face a situation where our level of economic cooperation [with the United States] might be less than it is today", and that she was concerned for Danish national security "as a country and as a Kingdom".

and the Danish Security and Intelligence Service indicated they were actively monitoring for potential attempts by foreign states to influence the outcome of the contest. In an interview with TV 2 (Danish TV channel), TV 2, independent analysts named the United States as one possible instigator of clandestine action in the country. The United States is Denmark's largest export market, accounting for more than 17 percent of all products the country sells externally, while Denmark is the United States' 29th largest export market, accounting for less than one percent of all products it sells externally. Jesper Daugaard Faurby, Danish Country Manager of Atradius, said that a trade war between the United States and European Union could cause the inflation to rise and result in bankruptcies of otherwise healthy companies. In April 2025, a plan by the United States for undermining the territorial integrity of the Kingdom of Denmark through a campaign of foreign interference and disinformation on social media became known. In May 2025, Trump stated that he could not rule out a U.S. millitary annexation of the island. In june 2025 Defense Secretary Pete Hegseth has officially declared Greenland part of the "U.S. homeland."


Danish plans and capabilities

According to defense researcher Kristian Søby Kristensen of the University of Copenhagen, Denmark "cannot defend Greenland against anybody on its own" and the Danish armed forces "are neither equipped nor trained to resist a U.S. invasion". Gad commented that a United States military-backed acquisition of Greenland would "be the shortest war in the world, there is no defensive capacity in Greenland". Marc Jacobsen, a professor at the Royal Danish Defence College, opined that "the US has de facto control [of Greenland] already". As of January 2025, Denmark's military stocks were significantly depleted due to recent arms transfers to Ukraine. In January 2025, a European Commission spokesperson stated Denmark could invoke the European Union's mutual defense provisions in the event of a U.S. invasion of Greenland. Daniel Fiott of the Brussels School of Governance stated that such an appeal would be "meaningless in its current form as there is no genuine military force behind it". Writing for ''Irish Legal News'', Federica Fazio questioned whether Denmark could, in fact, invoke the EU's mutual defense provisions in the event of the coercive annexation of Greenland as there is an outstanding question as to whether it is applicable in "Overseas Countries and Territories" of EU member states, such as Greenland. Fazio also noted that, as of 2025, some EU states—such as Italy and Hungary—would probably decline to provide assistance to Denmark altogether "and there is no sanctioning mechanism that could compel them to do otherwise". In late January 2025, the Chairman of the European Union Military Committee Robert Brieger called for the stationing of European Union military forces in Greenland. The proposal was immediately rejected by Danish defence minister Troels Lund Poulsen. It is a legal uncertainty if Denmark could invoke NATO's mutual defense clause to repel an attack undertaken by another NATO state. Besides ending sales of Ozempic to the United States, ''Foreign Policy (magazine), Foreign Policy'' suggested that Denmark could order Maersk and Lego to stop serving American customers as an economic disincentive for American invasion.


Legal framework

Under the Danish Penal Code, activities that unlawfully threaten Denmark's sovereignty or constitutional order, including through foreign interference or attempts to alter territorial integrity by illegal means, are criminalized under provisions relating to national security and crimes against the state.


Public opinion


Greenland

A 2019 article in Arctic Today claimed that about two-thirds of Greenlanders supported "the vision of independence from Denmark at some point in the future", but most believed that it would not be viable if it led to a cessation of Danish subsidies. The article went on to note that "president Trump’s notion that Greenland, including all of its 57,000 inhabitants with their distinct language, unique culture, democratic institutions and the rest of it could be sold and bought as a simple piece of real estate collided head on with all current views in Denmark and Greenland of normality, the status of the kingdom, the value of history and respectful interchange between peoples as the foundation of the current order of our times." The first survey of the island on foreign policy, by the Konrad Adenauer Foundation, Konrad Adenauer Stiftung Foundation in 2021, found that 68% of islanders wanted more cooperation with Denmark. Martin Breum of the Arctic Council said that the finding was not contradictory with the strong support for independence, as many supporters believe that post-independence cooperation with Denmark would be voluntary for Greenland. 69% of Greenlanders wanted more cooperation with the United States, and 75% viewed NATO positively. The survey found that 85% of islanders wanted more cooperation with Canada, which Breum interpreted as wanting closer ties with the Inuit of Nunavut and not with Canada as a whole; "If I am right, this might disturb a few influential people in Nuuk" who have deemphasized transnational Inuit ties and support for the Inuit Circumpolar Council, he said. A January 2025 poll of 416 residents of Greenland, conducted by the U.S. survey firm Patriot Polling, found that 57.3% of respondents approve of Greenland joining the United States, while 37.4% disapprove and 5.3% are undecided. The poll and the firm behind it was severely criticized by professor Scott Lucas from University College Dublin, however, who called the poll very suspect, criticizing the lack of information on how the respondents were chosen, which questions were asked, and what was its statistical uncertainty. He also named the firm behind it as a start-up organization having a political purpose performing push polls. The CEO of the organization, Lucca Ruggieri, came under criticism due to his ties to Republican donors and politicians. A poll of 497 adult residents of Greenland between 22 and 26 January 2025, made by Verian for the national Greenlandic newspaper '' Sermitsiaq'' and the national Danish newspaper ''Berlingske'', found that 85% of respondents rejected a proposition that Greenland should leave the Danish Realm to become part of the United States, whereas 6% supported the proposition and 9% were undecided. In the same poll, when asked whether they would prefer a Danish or an American citizenship, 55% preferred a Danish one and 8% an American one, whereas 37% were undecided. Furthermore, the poll explored opinions on Donald Trump's interest in Greenland: The results indicate that 45% of responders consider Donald Trump's interest in Greenland to be an opportunity, while 43% view it as a threat and 13% of answered "Don't know". The statistical uncertainty was reported as between 1.9% and 4.4%. Trump's interest in Greenland has strengthened the cause of Greenland's Greenlandic independence, independence from Denmark. Only the party leader of Qulleq (political party), Qulleq stated his support for Trump but the party failed to win any seats in the 2025 Greenlandic general election, 2025 regional election which was won by the moderate and highly Trump-critical Democrats. The separatist Naleraq which has pro-Trump members came in second place.


United States

A January 2025 poll of 1,000 U.S. registered voters conducted by Suffolk University found approximately 53 percent of respondents oppose acquiring Greenland, while 40 percent supported the idea. A poll of 6,933 U.S. adults by YouGov, fielded on January 8, 2025, found 31% "strongly support" or "somewhat support" the U.S. seeking ownership of Greenland, 35% "strongly oppose" or "somewhat oppose" such a move, and 34% weren't sure. Responses indicating strong support for the proposal were highest among men, 18 to 29 year-olds, and persons in the Southern United States. Responses indicating strong opposition to the proposal were highest among persons over the age of 65 and those in the Midwestern United States. A week later, another poll by YouGov joint with ''The Economist'', comprising 1,558 U.S. adults, reported that 28% supported the U.S. seeking ownership of Greenland, whereas 47% opposed this and 25% were not sure. About one-fourth of those in favor of U.S. ownership of Greenland, corresponding to 6% of all poll participants, supported using military force to take over Greenland. Another poll of 1,077 U.S. adults, conducted by Ipsos for

on January 20 to 21, showed little support for plans of extending U.S. territory, finding that only 16% of respondents agreed that the U.S. should pressure Denmark into selling Greenland to the U.S. and 21% agreed that the U.S. has a right to expand its territory in the Western Hemisphere.


Denmark

A January 2025 YouGov poll found that nearly half of Danes consider the United States a significant threat, surpassing concerns about North Korea and Iran, while 78% oppose selling Greenland to the United States. In response to Trump's statements during his second term, Danish residents issued Proposed Danish acquisition of California, a satirical petition for Denmark to purchase California from the United States, that went viral and attracted several hundred thousand Danish signatures in support. The petition parodied Trump's rhetoric as president, bearing the slogan "Måke Califørnia Great Ægain" and vowing to "bring hygge to Hollywood, bike lanes to Beverly Hills and organic smørrebrød to every street corner."
