Trump claims US gains permanent security control over Greenland in Denmark deal
On Friday, September 17, 2026, US President Donald Trump announced via Truth Social that he had struck a deal with Denmark granting the United States “permanent control” over Greenland’s security. The agreement reportedly provides the US with permanent access, basing, and overflight rights in Greenland, the authority to establish additional military installations as needed, and bars Russia and China from setting up any bases in the Arctic territory. Trump described the deal as “historic,” “special,” and a “dream come true,” saying it would cost the United States nothing.
For Nigerians, the development is largely distant but signals a shift in Arctic geopolitics that could influence global power balances, NATO cohesion, and access to critical minerals and emerging shipping routes—factors that may indirectly affect foreign investment, defense partnerships, or commodity prices relevant to Nigeria.
The deal also gives the US unilateral power to build new military structures on Greenland without approval from Greenland or Denmark, and prohibits non‑NATO countries from making investments there that Washington deems threatening. Trump linked the arrangement to his planned “Golden Dome” missile defence system and argued Denmark’s current defence spending on the island is insufficient. No specific cost or timeline for construction was disclosed. Readers should watch for official reactions from Copenhagen and NATO, as the arrangement may test existing sovereignty agreements and spark diplomatic debate.
