Secretary of State Marco Rubio has told U.S. lawmakers that Trump plans to buy Greenland, not invade it, even as President Donald Trump asks senior aides to deliver an updated strategy for acquiring the Arctic territory. The remarks, disclosed by U.S. officials on Tuesday, come amid heightened international scrutiny and growing concern among America’s closest allies.
Rubio made the comments during a closed-door briefing on Monday with members of the armed services and foreign policy committees in both the House and Senate. While the session was formally focused on Venezuela, lawmakers pressed Rubio for clarification about the administration’s intentions toward Greenland following a series of aggressive public statements by Trump and one of his top advisers, Stephen Miller.
According to two officials familiar with the briefing, Rubio attempted to reassure lawmakers that the president’s preferred path involved a transaction rather than military action. On the same day as the briefing, Trump instructed aides to prepare an updated plan outlining options for acquiring Greenland, underscoring that the issue remains a live priority inside the White House.
A long-standing ambition returns to the spotlight
Trump plans to buy Greenland is not a new idea. The president has expressed interest in acquiring the island since his first term, when he openly floated the idea of purchasing it from Denmark. At the time, the proposal was widely ridiculed by foreign leaders and dismissed outright by Copenhagen.
Yet Trump’s background as a New York real estate developer continues to shape his worldview. Several of his closest advisers, including diplomatic envoy Steve Witkoff, also come from real estate and business backgrounds. That perspective, officials say, has influenced how Trump frames territorial control, sovereignty, and strategic assets.
Greenland, sparsely populated and vast in size, has long captured Trump’s attention. The island occupies a critical position in the Arctic and is rich in untapped natural resources, including rare-earth minerals that are essential to modern technology and defense systems.
Greenland’s status and Denmark’s sovereignty
Greenland is an autonomous territory within the Kingdom of Denmark, a NATO ally and one of the United States’ closest partners in Europe. Denmark established colonial control over Greenland in the 18th century and gradually expanded self-rule throughout the 20th century, granting the territory broad autonomy over domestic affairs.
Today, Greenland manages its own internal governance but relies on Denmark for defense and foreign policy. Any attempt by an outside power to acquire Greenland without Danish and Greenlandic consent would violate international law and directly challenge NATO’s founding principles.
Those concerns came sharply into focus on Tuesday when leaders of six NATO nations joined Danish Prime Minister Mette Frederiksen in issuing a rare and forceful joint statement rejecting Trump’s assertions that the United States should take over Greenland.
NATO allies push back collectively
The joint statement was signed by leaders from Britain, France, Germany, Italy, Spain, and Poland—six of Washington’s most important allies. The coordinated response signaled deep unease within Europe about the direction of U.S. foreign policy under Trump’s renewed leadership.
“Security in the Arctic must therefore be achieved collectively, in conjunction with NATO allies including the United States, by upholding the principles of the U.N. Charter, including sovereignty, territorial integrity and the inviolability of borders,” the statement said. “These are universal principles, and we will not stop defending them.”
The leaders left little room for ambiguity about Greenland’s future.
“Greenland belongs to its people,” they added. “It is for Denmark and Greenland, and them only, to decide on matters concerning Denmark and Greenland.”
For European officials, the statement was not merely about Greenland. It was a warning that any attempt to coerce or pressure a NATO ally could undermine the alliance itself at a time when unity is critical.
The White House keeps military options on the table
Despite Rubio’s assurances that Trump plans to buy Greenland, the White House has refused to fully rule out more aggressive options. Karoline Leavitt, the White House press secretary, said in a statement that military force remains within the president’s authority.
“President Trump has made it well known that acquiring Greenland is a national security priority of the United States, and it’s vital to deter our adversaries in the Arctic region,” Leavitt said. “The president and his team are discussing a range of options to pursue this important foreign policy goal, and of course, utilizing the U.S. military is always an option at the commander in chief’s disposal.”
That language has alarmed lawmakers and allies alike, who fear that even rhetorical openness to military action could destabilize NATO and embolden adversaries.
Bipartisan concern on Capitol Hill
Some members of Congress have begun to publicly question the administration’s approach. On Tuesday evening, Senator Jeanne Shaheen, a Democrat from New Hampshire, and Senator Thom Tillis, a Republican from North Carolina, issued a rare bipartisan statement urging restraint.
The two senators lead the Senate NATO Observer Group, a bipartisan body tasked with strengthening ties between the U.S. Congress and the alliance.
“When Denmark and Greenland make it clear that Greenland is not for sale, the United States must honor its treaty obligations and respect the sovereignty and territorial integrity of the Kingdom of Denmark,” they said.
They warned that coercive tactics would contradict the values NATO was created to protect.
“Any suggestion that our nation would subject a fellow NATO ally to coercion or external pressure undermines the very principles of self-determination that our alliance exists to defend,” the senators added.
Trump’s Arctic claims draw scrutiny
Trump has repeatedly justified his interest in Greenland by citing threats from Russia and China. On Sunday, speaking to reporters aboard Air Force One, he claimed that “Greenland is covered with Russian and Chinese ships all over the place.”
While Russia and China have increased their presence and ambitions in the Arctic, experts say Trump’s characterization is inaccurate. Greenland is not surrounded by Russian or Chinese vessels. In fact, the only permanent foreign military presence on the island belongs to the United States.
The U.S. operates Pituffik Space Base, formerly known as Thule Air Base, a critical installation for missile defense and space surveillance. Vice President JD Vance visited the base last year alongside his wife, Usha, underscoring its strategic importance to Washington.
Security analysts argue that existing agreements already give the United States extensive access to Greenland without requiring ownership, raising questions about what additional benefits a purchase would actually provide.
Minerals, power, and strategic dominance
Another reason Trump plans to buy Greenland lies beneath its icy surface. Greenland is believed to hold significant reserves of rare-earth elements and other critical minerals used in electric vehicles, renewable energy technology, and advanced weapons systems.
China currently dominates global supply chains for many of these materials, a situation U.S. policymakers increasingly view as a strategic vulnerability. Control over Greenland’s resources could, in theory, help reduce American dependence on Beijing.
However, Greenland’s harsh climate, limited infrastructure, and strong environmental protections make large-scale mining difficult and costly. Many proposed projects have stalled due to local opposition and economic uncertainty.
Still, the symbolism of controlling such a resource-rich territory appears to resonate strongly with Trump’s broader vision of American power.
A wider strategy takes shape
The Greenland issue cannot be separated from the Trump administration’s broader geopolitical agenda. The second Trump administration’s National Security Strategy explicitly prioritizes dominance of the Western Hemisphere, signaling a more assertive posture toward neighboring regions.
That strategy has already been reflected in Trump’s aggressive approach toward Venezuela, culminating in the seizure of Nicolás Maduro and his wife, Cilia Flores, during a deadly U.S. military operation on Saturday. Earlier, Trump also stated that he planned to acquire Canada, a remark that drew disbelief but reinforced concerns about his views on sovereignty and borders.
Within this context, Greenland appears less like an isolated obsession and more like part of a larger effort to reshape America’s role in the world through power, leverage, and territorial control.
An unresolved and escalating debate
For now, Trump plans to buy Greenland remains an aspiration rather than a policy outcome. Denmark and Greenland have categorically rejected any sale, and NATO allies have drawn a clear line against coercion or force.
Yet the administration’s refusal to rule out extreme measures has ensured that the debate will continue to dominate diplomatic conversations in Washington, Brussels, and Copenhagen.
As Arctic competition intensifies and global power dynamics shift, Greenland has become a symbol of deeper questions about international order, alliance loyalty, and the limits of American ambition in the 21st century.
