The United States military is pushing to expand its footprint in Greenland, a move that could redefine Arctic security dynamics and reshape the balance of power between Washington, Copenhagen, and the autonomous government in Nuuk. Jeff Landry, the special envoy appointed by Donald Trump, wrapped up a contentious first visit to Greenland's capital this week, declaring that "the moment has arrived" for America to reclaim its Cold War-era presence on the Danish territory.
Why This Matters:
• Three new U.S. military bases are reportedly planned for southern Greenland, adding to the sole existing installation at Pituffik in the north.
• The 1951 defense pact (updated in 2004) already permits Washington to deploy additional troops and expand facilities with prior notification to Denmark and Greenland—no new treaty required.
• Greenland sits on the missile corridor between Russia and the U.S., and holds untapped deposits of lithium, cobalt, rare earth elements, and other minerals critical to defense and renewable energy sectors.
• Melting Arctic ice is opening new shipping routes, making the island a commercial and strategic chokepoint in the contest with China and Russia.
The Pentagon's Arctic Revival
At the height of the Cold War, the U.S. Armed Forces operated 17 installations and deployed more than 10,000 personnel across Greenland. Today, that presence has dwindled to a single facility: the Pituffik Space Base (formerly Thule Air Base), a radar and missile-warning hub vital to NATO's northern flank. Landry's visit signals a reversal of that decades-long retreat.
According to recent intelligence, the Pentagon is advancing plans to reactivate three installations in Greenland's south, including a site inspection of a disused World War II airfield at Narsarsuaq for potential troop housing. Washington is also negotiating modifications to the existing defense agreement that would guarantee a permanent American military presence—even if Greenland achieves full independence from Denmark—and seeks veto power over major foreign investments on the island to block Chinese or Russian influence.
Landry, the Republican governor of Louisiana, was not officially invited by Greenlandic authorities, and his trip sparked immediate controversy. Speaking to the Nuuk-based newspaper Sermitsiaq, he framed the issue as both a security imperative and an economic opportunity, stating that the U.S. could help Greenland "transition from dependence to independence." His language mirrors Trump's longstanding argument that American control—or at least oversight—of Greenland is essential to prevent the territory from "falling into the hands" of Beijing or Moscow.
What This Means for Arctic Geopolitics
Greenland is not merely a frozen expanse. It is a geographic pivot in the emerging great-power competition over the Arctic. For the U.S., the island is a northern anchor for missile defense, a buffer against Russian naval operations in the North Atlantic, and a potential source of rare earth minerals that could reduce dependence on Chinese supply chains. Trump has explicitly tied Greenland to his proposed "Golden Dome" air and missile defense system.
For China, Greenland represents a prize in its "Polar Silk Road" strategy. Beijing has sought to finance mining projects and infrastructure on the island, aiming to secure rare earth supplies and gain influence over emerging Arctic shipping lanes. Using the thawing northern route could cut up to 20 days off the voyage between Asia and Europe, saving billions in fuel costs. Chinese research stations and icebreakers in the region have raised Western concerns that scientific activity may serve dual purposes, including submarine surveillance data collection.
Russia, while focused primarily on its own Arctic coast and the Northern Sea Route, views any U.S. military buildup in Greenland as a potential threat to its naval operations and Arctic interests. Moscow has invested heavily in military infrastructure along its northern frontier and is wary of NATO expansion in the region.
Sovereignty vs. Security: The Local Perspective
Greenland's Prime Minister Jens-Frederik Nielsen has walked a diplomatic tightrope. Following a meeting with Landry, Nielsen described the encounter as "constructive" but stressed there was "no sign of change" in the U.S. position. Speaking at an economic forum, he called Trump's earlier rhetoric about "annexing" Greenland "completely disrespectful," but acknowledged the need to find a "solution."
Both the Government of Greenland and Denmark have repeatedly insisted that only Greenlanders can decide the island's future. Copenhagen has warned that any U.S. invasion of Greenland would effectively end NATO, and has coordinated with Norway, Sweden, Germany, and France to bolster its Arctic military presence. In June 2025, Denmark's parliament passed legislation allowing U.S. bases on Danish soil, though the law includes a clause permitting cancellation if Washington attempts annexation.
The 1951 defense agreement, revised in 2004, already grants the U.S. significant latitude. Washington can expand installations and deploy additional personnel as long as it notifies Denmark and Greenland beforehand. No new parliamentary approval is required. This legal framework is now the basis for the Pentagon's expansion plans, circumventing the need for fresh treaties or prolonged negotiations.
The Independence Paradox
Opinion polls show that a majority of Greenlanders favor eventual independence from Denmark. However, the government has no immediate plans to pursue it, largely because the island's economy remains heavily dependent on annual subsidies from Copenhagen. Greenland's GDP per capita is lower than Denmark's, and the extractive industries needed to replace that subsidy income—mining, oil, gas—face harsh operating conditions, poor infrastructure, and high capital costs.
Landry's pitch to Greenland is a calculated gamble. By framing U.S. investment and military presence as a path to economic self-sufficiency, Washington is positioning itself as a partner in sovereignty rather than a threat to it. Yet Greenlandic officials fear that accepting American terms could lock the island into a new form of dependency, trading Danish oversight for U.S. veto power over foreign deals and military access in perpetuity.
The situation echoes historical precedents. Gibraltar, a British overseas territory, retains sovereignty through an explicit veto clause requiring local consent for any transfer. Chagos, recently ceded by the U.K. to Mauritius, saw Britain maintain a 99-year lease on the Diego Garcia military base. The Faroe Islands, like Greenland, are an autonomous Danish territory where Copenhagen retains control of defense and foreign policy. These models illustrate the complexity of balancing military access with self-determination.
Trump's Strategic Calculus
Donald Trump has been the driving force behind Washington's renewed Arctic assertiveness. During his first term, he proposed purchasing Greenland outright—a suggestion dismissed by Denmark and Greenland as absurd. Since returning to office, Trump has moderated his language but intensified his actions. In January 2026, he claimed the U.S. would have "full and unlimited military access" to Greenland based on a NATO pre-agreement struck at Davos, a statement that was not confirmed by other parties.
Trump's interest is rooted in a mix of strategic threat assessment and resource nationalism. He views Greenland as a bulwark against Russian missile routes, a hedge against Chinese mineral dominance, and a necessary component of a hemispheric defense umbrella. Yet his approach has ruffled feathers in Copenhagen and Nuuk, where leaders insist that respect for sovereignty is non-negotiable.
In January, after international backlash, Trump stepped back from annexation threats, and a trilateral working group—comprising the U.S., Denmark, and Greenland—was established to address Washington's security concerns within existing legal frameworks. That group is now the forum for negotiating the scope and terms of any military expansion.
A Fragile Bargain
The outcome of these talks will determine whether Greenland becomes a model for negotiated security partnerships in the Arctic—or a flashpoint for transatlantic friction. For now, the island remains a Danish territory with broad autonomy, a single U.S. base, and a population of 56,000 weighing its future against the ambitions of three superpowers.
Landry's parting message to Greenlanders was blunt: "Greenland needs the United States." Whether Nuuk agrees—and on what terms—will shape the Arctic order for decades to come.
