WASHINGTON (Gray DC) - President Donald Trump announced Friday the U.S. has entered into an agreement with Denmark and Greenland, giving the U.S. what he called permanent control over the territory’s security.

Trump made the announcement on social media after months of insisting Greenland is crucial for U.S. security and threatening to take the island by force.

Trump wrote “the United States will forever have the complete ability to do what is necessary in Greenland in order to secure and defend the security of Greenland, and the United States of America.”

He added “no U.S. adversary can ever have a base in Greenland, have a military presence in Greenland, or make sensitive investments in Greenland, without our express written approval.”

Trump said the U.S. would immediately start developing a large military presence in the “appropriate part of Greenland.” He said the U.S. would work with the people of Greenland on development and construction.

Danish Prime Minister Mette Frederiksen said she was pleased with the agreement. She said it “strengthens our shared security in the Arctic and the North Atlantic, and therefore also benefits NATO and Europe. At the same time, the agreement recognizes the sovereignty and territorial integrity of the Kingdom of Denmark and the Greenlandic people’s right to self-determination.”

Frederiksen said the deal would be signed by the three governments next week during the United Nations General Assembly in New York.
