The island's importance to early warning and North Atlantic defence does not change with the composition of Congress.
Democratic control of both houses of the US Congress is likely to sharpen political resistance to any renewed attempt by President Donald Trump to pursue territorial acquisition or unilateral coercive measures, according to Troy Bouffard of the Center for Arctic Security and Resilience at the University of Alaska Fairbanks. Speaking to TASS, the military expert said that such resistance should not be confused with opposition to the strategic importance of Greenland itself, whose geographic position he described as central to North American defence, Arctic surveillance, early warning and the security architecture of the North Atlantic.
Bouffard's argument is that the United States does not require sovereignty over Greenland to achieve many of its most important security objectives. Cooperative defence arrangements, reliable access, infrastructure investments and sustained engagement with Denmark and Greenland, he said, can deliver substantial operational advantages without introducing unnecessary political friction within NATO. The claim rests on a distinction between access and ownership, and it is the sort of distinction that tends to be lost in the politics of an election campaign.
That politics has been active. According to the TASS report, Trump signed an agreement in September with the prime ministers of Denmark and Greenland, Mette Frederiksen and Jens-Frederik Nielsen, on the transfer of responsibilities for the security of the Arctic island to Washington. In late October, speaking at a rally for Republican supporters, Trump claimed that the Danish authorities had agreed to place Greenland under US control, and he posted an AI-generated image on Truth Social depicting the island as an American airbase. Danish Foreign Minister Lars Lokke Rasmussen characterised those statements as an attempt by the White House to secure a victory for Republicans in the midterm elections.
The gap between a security responsibilities agreement and a claim of control is the crux of the matter. One is a working arrangement among allies; the other is a question of sovereignty, which Copenhagen and Nuuk have not conceded on the record as reported here. Bouffard's assessment implies that the strategic substance of the September arrangement can survive a more combative Congress, provided Washington keeps its focus on cooperation rather than acquisition. Whether the White House accepts that framing is another question.
What is not yet known is considerable. The report gives no detail of the September agreement's terms, no indication of how far Democratic leaders intend to press the Greenland issue, and no confirmation from Danish or Greenlandic officials beyond Rasmussen's remarks. The expert's expectation of increased political resistance is a prediction, not a reported decision by Congress. Nor is it clear what practical leverage lawmakers would use, or whether Arctic security cooperation would itself become a partisan battleground.
For allies in NATO, the signal is mixed. A Congress inclined to scrutinise unilateral measures may be a stabilising force in the alliance, but a president who frames security arrangements as territorial victories can unsettle partners regardless of legislative arithmetic. The island's importance to early warning and North Atlantic defence does not change with the composition of Congress. The politics surrounding it does.
