Goodbye, Trans-Arctic cooperation? US-Greenland deal tightening encirclement of Russia

US President Donald Trump has recently announced a security deal with the Kingdom of Denmark and Greenland, a Danish autonomous territory. Previously, Washington had openly threatened it with annexation by force, if needed - thereby potentially undermining NATO itself.

In Trump’s words, the deal now gives the United States “permanent security control” over the vast Arctic island, allowing Washington to build a large military presence there.

NATO welcomed the pact. Danish and Greenlandic leaders, in turn, insisted that the agreement does not compromise territorial sovereignty or self-government. The text itself has not been fully released, so the full scope of it remains rather unclear.

Trump framed the outcome in characteristically blunt terms: an “infinite life” pact that hands the superpower lasting authority to “defend” Greenland and itself by whatever means it deems necessary. Copenhagen and Nuuk are careful to describe it as  something narrower: an expansion of existing military access that still respects Danish sovereignty.

In fact, the United States already enjoyed an extraordinarily favorable position there under the 1951 Defense of Greenland Agreement.

That Cold War-era framework, subsequently amended - including by a major 2004 agreement - has regulated the American presence for decades. Today, that presence centers on Pituffik Space Base, formerly Thule Air Base, with two more planned.

The installation provides ballistic-missile warning, space surveillance and Arctic monitoring deemed vital to North American defense.

What has changed is scale and permanence: the new pact reportedly expands the US footprint, locks in American rights - even if the island moves toward independence; and restricts non-NATO adversaries from establishing military facilities or sensitive infrastructure there.

In short, it deepens Greenland’s integration into the Western security architecture while denying strategic space to others.

In a sense, the American threats worked: months of annexation rhetoric, provocative maps, and pressure on Denmark produced concessions - despite European talk of “standing up” to such a menacing “ally”.

Yet these concessions may encourage further demands: one cannot appease a bully. And given Trump’s record of treating agreements or legal constraints as bargaining instruments (and of twisting or breaking the law), a larger US military presence could allow Washington to stretch or ignore narrower Danish interpretations.

The development also fits a wider pattern of Arctic militarization and strategic competition. The Atlantic Alliance launched Arctic Sentry this year, while America is investing in icebreakers and other polar capabilities.

Greenland lies along the GIUK Gap, a critical passage between the Arctic and North Atlantic used by Russian Northern Fleet submarines. Yet a January Carnegie analysis found no signs Moscow intended to turn the island into a military front line, describing Russian policy instead as focused on deterring Western military infrastructure in the region. It added that the prospect of an “unscrupulous” US “takeover” was more dangerous to Denmark and the Arctic than the “supposed threats from China and Russia”.

This Danish territory is thus being integrated more tightly into a strategic  security arc stretching from Alaska and Canada through the region; and the North Atlantic to Iceland and Norway.

The result is a classic security dilemma: Washington sees growing Russian Arctic activity and responds with more bases and radars; Moscow, in turn, sees expanding Western military infrastructure near its northern flank and nuclear deterrent.

This cycle also makes any future pragmatic European and Canadian cooperation with Moscow on non-military Arctic issues (search and rescue, fisheries, shipping safety and environmental monitoring) more difficult. As I have argued, geography itself demands Trans-Arctic joint action. Washington has become an increasingly unpredictable and hostile variable, making such efforts even harder.

Beijing’s growing polar research, shipping and resource interests have heightened US concerns about Chinese strategic access - and the new pact reportedly gives Washington a veto over sensitive investments by its adversaries in Greenland.

Growing Russian-Chinese collaboration in this resource-rich region is likewise viewed in the West as a challenge. American menaces against both Canada and Greenland have also been closely tied to energy interests. It is no wonder the White House presents the agreement as a strategic win against both powers.

The Arctic is unlikely to replace Ukraine as an active battlefield - but its stakes are broader: North American defense, nuclear deterrence, submarines, space surveillance, undersea cables, shipping routes and resources all converge there.

Any serious incident in such a theater carries escalation risks that conventional fighting farther south does not.

Trump’s deal thus institutionalizes a stronger US-NATO position in the region. That is the real substance behind his claim of “permanent control”: it represents the conversion of an already privileged military presence into a more permanent and explicitly exclusionary architecture.

Moreover, from Moscow’s perspective, it adds fuel to the wider  Baltic Question too, further encircling Russia from the north, thereby increasing tensions - trans-arctically and trans-atlantically.
