US-Denmark-Greenland Deal Expands Arctic Security Access

US-Denmark-Greenland Deal Expands Arctic Security Access

The United States, Denmark and Greenland signed a new agreement about protecting Greenland and the Arctic.

Greenland remains under Danish control, so the agreement does not give the island to the United States.

The deal lets the United States build or use military facilities at Narsarsuaq and Mestersvig.

It also lets the United States expand work at Pituffik Space Base and use Greenland’s airspace more freely.

The agreement allows a US Golden Dome defence system to be established there.

Countries outside NATO cannot set up military facilities in Greenland, and some foreign investments will face restrictions.

If Greenland becomes independent, the agreement says it should remain connected to NATO.

Supporters say the arrangement could make the Arctic safer, while critics worry that it gives Washington too much influence.

The full practical meaning of Trump’s claim of “permanent control” remains uncertain.
