Por Renan Filho · 2026-09-28The wind doesn’t blow in Greenland — it attacks. At 76 degrees below zero, the air itself becomes a physical force, searing exposed skin in seconds, freezing the moisture in your breath into a crystalline fog that hangs in front of your face like a warning. It was there, standing on the ice sheet that covers 80 percent of the world’s largest island, that I understood why the Trump administration’s renewed push to establish permanent U.S. military bases on Greenland is not merely a geopolitical gesture — it is a strategic imperative that could reshape Arctic defense for decades.
For years, the Arctic was a backwater of great-power competition, a frozen no-man’s-land where only scientists and a few hardy indigenous communities dared to operate. But the melting ice caps have changed everything. The Northwest Passage is opening, natural resources are becoming accessible, and Russia has been quietly modernizing its northern fleet, building new icebreakers and reopening Soviet-era bases along its Arctic coastline. China, too, has declared itself a “near-Arctic state” and is investing billions in polar research and infrastructure. The United States, meanwhile, has been playing catch-up — and Greenland is the key to closing that gap.
President Donald Trump first floated the idea of buying Greenland in 2019, to widespread mockery. But the strategic logic was never about real estate; it was about geography. Greenland sits astride the shortest route between North America and Eurasia, a natural chokepoint for any missile or bomber flying over the polar cap. The existing U.S. base at Thule, now Pituffik Space Base, is already the northernmost installation in the U.S. military, providing early-warning radar and missile defense. But it is aging, underfunded, and limited in capacity. Trump’s proposal — now backed by a new congressional task force and a series of high-level Pentagon studies — would expand that footprint with additional runways, deep-water ports, and missile defense batteries, transforming Greenland into a forward operating base for the 21st century.
I traveled to Greenland in March 2026, embedded with a U.S. Air Force logistics team testing cold-weather equipment for a potential base expansion. The mission was simple: assess whether the infrastructure could survive the environment. The answer, after three days on the ice, was both humbling and clarifying. Nothing works as it does in temperate zones. Diesel fuel turns to gel. Batteries drain in minutes. Metal becomes brittle enough to shatter. Even the most advanced Arctic-grade clothing fails if you stop moving for more than a few minutes. The soldiers I accompanied moved in short bursts, their breath freezing into ice masks, their radios crackling with static from the aurora borealis. One sergeant told me, “This place doesn’t forgive mistakes. It just punishes them.”
That reality is the core of the strategic argument. The Arctic is not a conventional battlefield; it is an environment that imposes its own brutal logic. Any military force that operates there must be equipped, trained, and supplied to a standard that most nations simply cannot meet. The United States, with its vast defense budget and technological edge, is one of the few countries that can even attempt it. But it requires permanent infrastructure — not just temporary deployments. That is why the Trump administration’s push for bases is so significant. It signals a shift from a reactive posture to a proactive one, from monitoring the Arctic to dominating it.
Critics argue that the move is provocative, that it will escalate tensions with Russia and undermine diplomatic efforts to keep the region peaceful. They point to the Ilulissat Declaration of 2008, in which Arctic states agreed to resolve disputes through law rather than force. But the world has changed since then. Russia’s invasion of Ukraine shattered the post-Cold War security order, and Moscow has militarized the Kola Peninsula, home to its Northern Fleet, with new hypersonic missiles that can reach the U.S. East Coast in under 15 minutes. China is building a research station in Svalbard and has signed a free trade agreement with Iceland. The Arctic is no longer a zone of cooperation; it is a theater of competition. To ignore that is not diplomacy — it is dereliction.
From a liberal-conservative perspective, the case for expanding U.S. presence in Greenland is straightforward. National defense is the first duty of government, and the Arctic is now the front line. The free market alone cannot provide for collective security; that requires state action, and a minimal state must act decisively where its core functions are at stake. The cost of building new bases — estimated at $12 billion over the next decade — is a fraction of what the U.S. spends on foreign aid or entitlement programs. And it is an investment in deterrence, not aggression. The goal is not to fight a war in the Arctic; it is to prevent one by making the cost of aggression prohibitive.
The economic dimension is equally compelling. Greenland is rich in rare earth minerals, uranium, and oil — resources that are increasingly critical for technology and energy security. The United States currently imports over 80 percent of its rare earth elements from China, a vulnerability that Beijing has already exploited in trade disputes. By securing a foothold in Greenland, Washington can diversify its supply chains and reduce its dependence on a strategic rival. This is not colonialism; it is partnership. The Trump administration has proposed a deal that would invest billions in Greenland’s infrastructure — ports, airports, hospitals, and schools — in exchange for long-term leases on military land. The Greenlandic government, which has autonomy over its natural resources, would gain a reliable source of revenue and development. It is a win-win arrangement that respects local sovereignty while advancing mutual interests.
But the challenges are immense. The logistics of building in the Arctic are staggering. Construction season lasts only a few months, and every piece of material must be shipped in by icebreaker or airlift. The environmental impact is a concern, though modern engineering can mitigate it. And there is the human factor: the Greenlandic population is small, scattered, and deeply attached to its traditions. Any large-scale military presence will inevitably disrupt their way of life. That is why the plan must be transparent, consultative, and respectful. The United States cannot impose its will; it must earn trust. That is a lesson I learned not from policy papers, but from the faces of the Danish and Greenlandic officials I met in Nuuk, who were cautiously optimistic but wary of being used as a pawn in great-power games.
My time at 76 below zero taught me something else: the Arctic is not a place for abstractions. It is a place where decisions have immediate, physical consequences. A frozen fuel line can ground an entire squadron. A cracked windshield can blind a pilot. A misread weather report can kill a patrol. In that environment, the margin for error is zero. That is why the United States must be prepared — not just with rhetoric, but with concrete assets on the ground. The bases Trump proposes are not a provocation; they are a necessity. They are the difference between being a spectator in the Arctic and being a player.
As I boarded the C-130 for the flight back to Thule, the sun was setting over the ice, painting the horizon in shades of orange and purple. The cold had seeped into my bones, and I knew I would never fully warm up. But I also knew that the men and women who serve in this environment, who endure conditions that would break most people, deserve a government that takes their mission seriously. The Arctic is the next great frontier of global power, and the United States cannot afford to be absent. The question is no longer whether to build bases in Greenland, but how quickly we can do it — and whether we have the will to see it through.

**Q: Why is Greenland strategically important for the U.S.?** A: Greenland sits on the shortest ballistic missile trajectory between North America and Russia, making it a vital early-warning and defense position. Its location also controls access to the Arctic shipping lanes and is rich in critical minerals.
**Q: Is the U.S. trying to buy Greenland?** A: No. The proposal is for long-term leases on land for military bases, combined with investment in Greenland’s civilian infrastructure. Greenland remains a self-governing territory within the Kingdom of Denmark.
**Q: Will this escalate tensions with Russia?** A: It could, but Russia has already militarized the Arctic. The U.S. response is defensive, aimed at deterrence. The alternative — doing nothing — would leave the Arctic open to Russian and Chinese dominance.
**Q: What are the environmental concerns?** A: Building in the Arctic is disruptive, but modern techniques can minimize impact. The U.S. military has a record of environmental stewardship in the region, and any expansion would follow strict regulations.
**Q: How much will this cost?** A: Estimates range from $10 to $15 billion over a decade, depending on the scope. This is a small fraction of the U.S. defense budget and a wise investment in long-term security.
**Q: What does Greenland get out of it?** A: Infrastructure development, job creation, and a stable source of revenue. The deal is designed to be mutually beneficial, respecting Greenlandic autonomy and environmental standards.
**Q: Is this a new Cold War?** A: Not in the classic sense, but great-power competition is back. The Arctic is a key arena, and the U.S. must be prepared to defend its interests without ceding the region to rivals.
