So President Trump was not just shooting off about acquiring Greenland at all. It has really happened.
Yesterday September 22, 2026, at the UN headquarters in New York, President Donald Trump, Danish Prime Minister Mette Frederiksen, and Greenlandic Prime Minister Jens-Frederik Nielsen signed an agreement. It amends and supplements the existing 1951 U.S.–Denmark Greenland defense agreement. Here is a quick video:
Much greater U.S. military access: The U.S. can expand its military presence and operations in Greenland.
- New U.S. defense areas: The agreement specifically provides for U.S. facilities at Narsarsuaq and Mestersvig, alongside expansion of the existing Pituffik Space Base.
“Golden Dome” missile defense: The agreement explicitly allows the U.S. to establish a missile-defense system in Greenland.
Broad military access: U.S. aircraft, ships and forces receive extensive rights to move through Greenland and its territorial waters in support of defense operations.
Excludes non-NATO military presence: Non-NATO states cannot establish military installations or a persistent military presence in Greenland without agreement.
Limits sensitive foreign investment: Investors from non-NATO/non-EU states can be restricted from controlling or significantly influencing strategically sensitive Greenlandic sectors.
- Greenland remains Danish: The agreement explicitly reaffirms the sovereignty and territorial integrity of the Kingdom of Denmark and Greenlanders' right to self-determination. It does not make Greenland U.S. territory.
- Even if Greenland becomes independent: The agreement is designed to continue if Greenland later becomes independent, including provisions for continued NATO membership and U.S. defense arrangements
