Claims analyzed (7)

  1. verified: This Truth Social post was posted by Donald J. Trump on September 18, 2026.
    Multiple news sources confirm that President Donald Trump made an announcement on his Truth Social platform on September 18, 2026, regarding a security agreement with Denmark and Greenland, quoting directly from his post.
  2. mostly true: The United States of America has entered into an Agreement with The Kingdom of Denmark, and Greenland, that gives the United States permanent control over security, and all other needs, in Greenland.
    President Trump announced an agreement on September 18, 2026, stating it gives the US "permanent control over security, and all other needs, in Greenland." News reports confirm an agreement was reached to bolster the US military presence and security interests in Greenland. However, Danish and Greenlandic officials have emphasized that the deal respects their sovereignty and is a framework, not an outright transfer of control.
  3. mostly true: The agreement completely addresses all U.S. concerns.
    President Trump stated the agreement "completely addressing ALL of our many U.S. concerns." Secretary of State Marco Rubio also stated the deal "permanently and completely addresses our national security concerns in Greenland." However, the full details of the agreement are not yet public, and Danish officials have indicated the agreement is a framework, suggesting ongoing discussions.
  4. unverifiable: There will be no cost to the United States for this agreement.
    President Trump stated there would be "NO COST to the United States!" for the agreement. A US State Department official also described it as guaranteeing US security interests "at no cost to the American taxpayer." However, the agreement's full text and financial implications have not been publicly detailed, making it difficult to fully verify this claim.
  5. mostly true: The United States will forever have the complete ability to do what is needed in Greenland.
    President Trump stated the US will "FOREVER have the complete ability to do what is necessary in Greenland." News reports confirm the agreement is described as "permanent" and "indefinite" regarding US security rights and military presence. However, Danish and Greenlandic officials maintain their sovereignty, implying the US ability to act is within the agreed-upon framework and not absolute.
  6. mostly true: President Trump secured an "Infinite Life" agreement with the Kingdom of Denmark.
    President Trump referred to the agreement as "Infinite Life" in his Truth Social post. News reports also quote Trump using this phrase. The agreement is described as having no end date, but the term "Infinite Life" is Trump's phrasing.
  7. misleading: Donald Trump is the first President to address this need and secure such a deal.
    While President Trump has actively pursued a new agreement, the US has had a significant military presence in Greenland since World War II, and a 1951 treaty with Denmark already grants Washington broad latitude for bases. Previous US administrations have also shown interest in Greenland.
