Washington has written a sphere of influence into a treaty and called it security

23rd September 2026 – (New York) The document signed in New York on Tuesday runs to ten pages. It took months to draft, and the diplomats who wrote it waited for what they judged the right moment to place it before Donald Trump, wary that he might renounce it the following morning as he did with a Saudi nuclear agreement over the summer. What emerged is a trilateral security pact between the United States, Denmark and Greenland that its own signatories are anxious not to describe too precisely. Trump calls it “permanent control”. Copenhagen and Nuuk call it a reaffirmation of sovereignty. Both descriptions are being allowed to stand, because the alternative is reopening a dispute that nobody in Europe wishes to revisit.

It is worth setting out what the agreement actually does. The United States may build two new military sites, at Narsarsuaq in the south and Mestersvig on the east coast, adding to the Pituffik Space Base it already operates. It may deploy elements of the planned Golden Dome missile defence system. Its aircraft and vessels gain broad access to Greenlandic territory and waters. Non-NATO states are barred from military installations. And, most consequentially, investors from outside NATO, its partner states and the European Union are restricted from gaining control or significant influence in critical infrastructure and resource extraction. The agreement has no expiry date and binds Greenland even if it one day leaves the Danish realm.

Analysts across Denmark, Singapore, Australia and Britain have converged on a single judgment i.e. most of this was already available under the 1951 defence agreement and its 2004 revision. At the height of the Cold War, Washington maintained 17 installations and more than 10,000 personnel on the island without any new treaty. Mikkel Runge Olesen of the Danish Institute for International Studies calls the outcome “a moderate improvement for the U.S.” achieved at “an extraordinarily high price”. Marc Weller of Chatham House describes the basing question as “a non issue”. The military expansion, in other words, is theatre built on rights that already existed.

What is genuinely new lies elsewhere, and it deserves closer attention than it has received. For the first time, a third country holds a formal veto over who may invest in another territory’s mines, ports and infrastructure. The provision is not disguised. Elizabeth Buchanan of the Australian Strategic Policy Institute states plainly that it is designed to make it harder for China to gain a foothold, and concedes that the Russian case is “a stretch” since Moscow already possesses ample Arctic territory from which to operate. The clause, then, is written with one country in mind.

In 2016, a Chinese company expressed interest in purchasing a decommissioned naval station at Kangilinnguit. In 2018, a Chinese construction firm bid to participate in Greenland’s airport project. Both were commercial propositions, both were blocked by Danish intervention at Washington’s urging, and neither involved a soldier or a missile. China has published an Arctic policy describing itself as a near-Arctic state with interests in research, shipping and resource cooperation, conducted through the same channels used by Japan, South Korea and the European Union. None of those states appears on the list of the excluded. The distinction is not between military and civilian activity. It is between nations Washington approves of and nations it does not, and it has now been fixed in a text that can be amended only by mutual consent, without end.

Buchanan describes the resulting arrangement as “akin to a US protectorate”. That is a candid word from a friendly analyst, and it points to a contradiction Western capitals have been reluctant to examine. The United States has spent the past decade warning smaller nations about the dangers of economic dependence on China, about debt, about infrastructure investment as a Trojan horse for strategic influence. It has now secured, through eighteen months of threats against a NATO ally, the legal right to decide which foreign companies may operate in a territory of 57,000 people. Imran Bayoumi of the Atlantic Council asks a fair question: if Washington intends to veto others’ investment, is it prepared to fund the development Greenlanders actually need? Trump’s answer, posted on Truth Social, is that there will be “NO COST to the United States”.

This agreement was not the product of patient alliance management. It followed public demands for ownership, a vice-presidential visit to a base to declare that allies had buried their heads in the snow, and a sustained period in which Europeans genuinely feared military action against one of their own. Rasmus Sinding of DIIS observes that a comparable arrangement could probably have been reached through conventional diplomacy. Tillie Martinussen, a former Greenlandic parliamentarian, puts it more directly: Greenlanders “will never forget that he threatened us”.
