Trump Says US Has ‘Permanent Control’ Over Greenland Security: Does it?

The United States’ recent agreement with Denmark on Greenland’s security has sparked a mix of reactions, from jubilation in some quarters to skepticism and outright criticism in others. At its core, this deal promises “permanent control” over Greenland’s security and “all other needs,” but what does that really mean for the island nation?

Greenland, an autonomous territory within the Kingdom of Denmark, has long been a strategic prize due to its location in the Arctic. The 1951 treaty between the US and Denmark already grants Washington broad overflight and basing rights on the island, including control over landings, takeoffs, anchorages, moorings, movements, and operation of ships, aircraft, and waterborne craft.

President Trump has described this new agreement as an “Infinite Life Agreement,” which means that the US will have carte blanche to build military bases on Greenland without needing approval from either Denmark or Greenland itself. However, Imran Bayoumi, a former Pentagon official, notes that many of these objectives could have been achieved through diplomacy and dialogue without straining the broader US-NATO relationship.

The deal also bars non-NATO states – specifically China and Russia – from establishing military presence or making “sensitive investments” in Greenland. But what constitutes a sensitive investment? And who gets to decide which countries qualify as adversaries?

Behind the rhetoric about “permanent control,” lies a more complex web of interests. The US has long been seeking to expand its access to rare-earth metals, which are in short supply globally. Greenland’s rich deposits of zinc, iron, uranium, and graphite would be a major prize for any nation looking to secure these strategic resources.

Greenlanders themselves seem to have mixed feelings about the deal. In 2025, an overwhelming majority (85%) opposed becoming part of the US. While some see it as a positive development that ends the crisis caused by Trump’s earlier threats, others remain wary of ceding control over their territory.

Ultimately, this agreement may be less about Greenland’s security and more about the interests of global powers vying for influence in the Arctic. As Olesen notes, the deal could have far-reaching implications for other countries, potentially labeling them as adversaries subject to similar restrictions.

The US already operates a Space Force base on Greenland’s Pituffik Peninsula, staffed by over 100 personnel. Trump has promised to “immediately” build up a large military presence on the island, but what exactly this entails remains unclear. Will it involve new bases, expanded infrastructure, or simply an increased troop deployment?

One thing is certain: Greenland’s security shield has become a pawn in the global game of geopolitics. As nations jockey for position in the Arctic, the stakes have never been higher. It remains to be seen whether this agreement will truly bring “permanent control” or merely create a facade of stability – but one thing is clear: the consequences of this deal will be felt far beyond Greenland’s shores.
