Trump’s Greenland claim falters under a century of sovereignty records

CNN fact-checks Trump’s extraordinary message to Norway, debunking his claim that there are no written documents proving Denmark’s sovereignty over Greenland. The piece cites multiple historical documents and agreements—from the 1916 Lansing Declaration to post‑war treaties and Greenland’s 2004 Home Rule—that reaffirm Danish sovereignty, and it notes Greenland’s earlier Danish‑Norse settlement history and U.S. recognition of Denmark’s sovereignty, showing Trump’s claim is false.
