Trump announces Greenland deal | 18 Sep 2026 | The U.S. will effectively control Greenland’s security under an agreement reached with Denmark and the self-governing Arctic territory, President Donald Trump has announced. In a Truth Social post on Friday, Trump said the agreement “gives the United States permanent control over security, and all other needs, in Greenland, completely addressing ALL of our many U.S. concerns.” “At my direction, we worked with representatives of Denmark and Greenland to guarantee that 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. “Additionally, from now on, 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 promised that the U.S. would be “very protective” of Greenland, describing the deal as “a dream come true for the United States of America.”
