## Trump announces 'infinite' Greenland deal
President Trump said the US reached an agreement with Denmark and Greenland for permanent control over security and strategic needs. The deal prevents any US adversary from having a military base or making sensitive investments there without American approval.

> This is an "Infinite Life" Agreement, there is no end!
## The deal hasn't been signed yet
Almost nothing is known about the agreement beyond Trump's social media posts. Denmark and Greenland both stated that any deal would not compromise Greenland's sovereignty, suggesting Trump's annexation threats are off the table.
## US military already has sweeping access
The US military has enjoyed broad access to Greenland since a 1950s treaty. Service members are currently the single largest group of Americans in the territory, so Trump's expansion claims may be overstated.
## Trump wants rare earth minerals and oil
Trump has cited Russia and China as threats, but his real focus is Greenland's rare earth minerals and oil reserves. A US company just paid over 35 million dollars for the Sarfartoq Rare Earths Project in southwest Greenland.
## Greenlanders are protesting the deal
Thousands of Greenlanders marched against Trump's threats in early 2026. Ninety percent of Greenland's population is Indigenous, and a majority supports independence from Denmark, let alone the United States.
## Local skepticism about what's really happening
Ellen Frederiksen, a retired teacher in Narsaq, said the deal makes her nervous. She worries Trump is being given a monopoly over Greenland, and hopes that isn't what the agreement actually says.

> The way Trump presents it, it sounds as if he is being given a monopoly over Greenland.
## Key takeaway

Trump secured expanded military and strategic control over Greenland without annexation, but the vague deal has sparked Greenlandic protests and concerns about sovereignty.
