Trump Claims 'Permanent Control' Over Greenland's Security in New Deal With Denmark
President Trump announced Friday that the United States and Denmark reached a security agreement giving Washington what he called "permanent control" over Greenland's security "and all other needs," a claim that falls short of the outright US ownership he pushed for last year. A State Department official said the deal bars US adversaries from establishing a military presence or making "sensitive investments" on the island without US approval. Denmark and Greenland acknowledged the agreement Friday but did not release specific terms, saying details would follow next week.
The announcement comes 17 days after Greenland Mines, a NASDAQ-listed, US-aligned firm headquartered in North Carolina, closed a deal for the Sarfartoq Rare Earths Project in southwest Greenland, a mine that could produce more than a third of the world's rare earth magnet supply outside China. Greenland holds an estimated 1.5 million tons of rare earth reserves, the eighth-largest deposit in the world, though reaching them requires drilling through hundreds of feet of ice. Trump has repeatedly said his interest in Greenland is about national security rather than minerals, even as his administration works to build supply chains that bypass China, which controls roughly 60 percent of the world's known rare earth deposits.
The deal updates a 1951 agreement between the US and Greenland that already gave American forces free access to the island's defense areas. It marks the latest step in more than a year of on-and-off pressure from Trump on Denmark and Greenland, after he floated outright US ownership of the Danish territory in early 2025, a push that had strained relations with the NATO ally.
Arguments for:
Securing formal, long-term access to Greenland strengthens US missile defense and Arctic positioning against Russian and Chinese activity in the region.
Locking down rare earth access outside China reduces US dependence on a supply chain Beijing has repeatedly restricted through export controls.
Updating a 74-year-old treaty gives both countries clearer rules for military access instead of relying on Cold War-era terms.
Arguments against:
Denmark and Greenland gave no specifics on the deal's actual terms, leaving open questions about what the US gained beyond a rhetorical claim of "permanent control."
The timing, just after a US-aligned firm closed on a major rare earth mine, raises questions about how separate the "security" framing really is from mineral interests.
Trump's earlier threats to seize Greenland outright already strained trust with a NATO ally, and a vague, undetailed agreement may not fully repair that relationship.
