36 US military waste sites complicate Greenland access

Diesel-soaked soil, heavy metals, low-radioactive wastewater. Across Greenland's ice and tundra, at least 36 former US military sites carry the residue of Cold War operations, according to a Politiken investigation based on Danish and Greenlandic environmental documents. The findings land as Washington actively seeks renewed strategic access to the island. Bloomberg reports that Denmark expects high-level talks to produce a deal by year's end.

Greenland's leverage depends on whether cleanup becomes part of the access bargain, or whether old contamination and new military plans are handled separately.

Power Split Between Nuuk and Copenhagen

Greenland has governed most of its internal affairs since the 2009 Self-Government Act. Defence and foreign policy remain with the Kingdom of Denmark. The standing framework for US military presence is the 1951 US-Denmark Defence Agreement, signed when Greenland had no voice at all.

That formal structure gives Copenhagen the signature on any new deal. But Greenlandic communities live with the contaminated sites. Any agreement signed in Copenhagen without political support in Nuuk would be fragile from the start. Yle reported that Greenland and the Faroe Islands are pushing for greater say over their own foreign-policy positions, a demand that gains weight when the territory under discussion is the same territory absorbing the environmental cost.

Why Washington Wants Back In

The US military case for Greenland is geographic. The island sits on the shortest air and missile routes between North America and Russia. NATO describes the Arctic as increasingly central to allied defence, and the US already operates Pituffik Space Base (formerly Thule) for early warning and space surveillance.

The broader problem is that surveillance, communications and early-warning systems work badly across the High North without ground infrastructure. According to Reuters, allies have promised to close that gap but have yet to build the radars, sensors and stations required. Russia's nuclear-armed Kola Peninsula sits across the water. Denmark itself is sending conscripts to Greenland, signalling it wants to demonstrate Arctic responsibility rather than leave the field to Washington.

The Unresolved Bill

The contamination findings undercut the image of the US as a clean-handed security partner. The infoLibre/EIC republication of the Politiken investigation connected the pollution to an alleged 1991 US promise to remove hazardous substances from vacated installations. Denmark, according to that reporting, has absorbed part of the cleanup cost without US contribution. The primary text of the 1991 commitment has not been independently retrieved, so it remains a strong lead rather than a confirmed legal obligation.

German and Nordic coverage pushed in the same direction. Arte centred Greenlandic Inuit identity and self-determination. POV International framed US interest through defence geography while insisting that any step taken against Greenlandic will would lack legitimacy. Camp Century, a Cold War base buried under the ice sheet, remains the emblematic case: abandoned military infrastructure in Greenland does not stay buried forever.

The Bargain Ahead

No source across Nordic, German, Dutch or Spanish coverage confirmed a formal "cleanup first, access later" condition in the current negotiations. The political case is visible everywhere: pollution deepens distrust, Greenlandic consent matters, and allies should not dump costs on the communities hosting their defence infrastructure. But that case has not hardened into a published condition.

If cleanup stays separate from access talks, Washington gains room to expand its military presence without paying the full price of past contamination. Copenhagen preserves the alliance relationship. Greenland loses its strongest card: the ability to bundle accountability for old damage with consent for new presence. And if Nuuk objects after a deal is signed, it has no formal veto over defence agreements. Its only tool is the political cost it can impose on a Danish government that needs Greenlandic cooperation to make any agreement work on the ground.

The people living there are still waiting for the last round to be cleaned up.
