Trump signs Arctic security pact with Denmark and Greenland

U.S. President Donald Trump signed a landmark 10-page security pact with Danish Prime Minister Mette Frederiksen and Greenlandic Prime Minister Jens-Frederik Nielsen on Tuesday, cooling months of diplomatic friction over White House proposals to gain strategic control of the autonomous territory.

What are the key military provisions and base expansions under the deal?

The tri-party agreement grants the United States authority to build two new major military installations in Greenland—one at Narsarsuaq in the south and another at Mestersvig in the east—alongside expanding the operational footprint and modernization efforts at Pituffik Space Base in the north. The pact also integrates Greenland into Washington's proposed "Golden Dome" air and missile defense architecture, ensuring extensive overflight, landing, and maritime rights for U.S. forces across the strategic Arctic corridor.

Under the terms of the accord, non-NATO and non-EU entities are strictly barred from establishing military facilities or taking controlling stakes in sensitive infrastructure and critical rare earth mining sectors. White House officials emphasized that the deal has no expiration date and dictates that Greenland must maintain its alliance commitments within NATO even if the territory chooses full independence from Denmark in the future.

How did Danish, Greenlandic, and European leaders react to the signing?

Danish Prime Minister Frederiksen welcomed the accord as a "deal that can last forever," noting that while it expands American defense capabilities, it explicitly reaffirms the territorial integrity and sovereignty of the Kingdom of Denmark.

Greenlandic Prime Minister Nielsen stated that the arrangement balances North American security requirements with local rights, declaring it a "win-win-win agreement" that establishes clear boundaries against foreign adversaries.

According to reporting by PBS NewsHour and The Washington Post, European Union leaders and NATO Secretary-General Mark Rutte praised the framework for bolstering collective transatlantic defense across the High North. The agreement will enter into force following formal parliamentary ratification in Copenhagen and Nuuk.
