US and Denmark announce security agreement on Greenland after Trump annexation threats

Agreement announced

The United States and Denmark said they will sign a security agreement concerning Greenland at the United Nations General Assembly next week, according to statements from Danish Prime Minister Mette Frederiksen and Greenland Government Chairman Jens-Frederik Nielsen. Both officials described the pact as strengthening security in the Arctic and North Atlantic while recognizing Greenland’s sovereignty and the right to self-determination.

Claims about the deal’s content

A US State Department official, who was not named, outlined provisions that reportedly give the United States permanent access, basing and overflight rights, and allow unilateral construction of additional military facilities without further approval from Greenland or Denmark. The official also said the agreement would prohibit non-NATO countries from establishing bases in Greenland and block investments in “sensitive sectors” by adversaries such as Russia and China. No text of the agreement has been made public.

Context and unresolved questions

The announcement follows months of statements by Donald Trump on his social platform, in which he threatened to seize Greenland and claimed the deal would cost the United States nothing while granting the ability to prevent adversary military presence and investments. US Secretary of State Marco Rubio called the arrangement a historic win for the United States. It remains unclear how the new pact differs from the 1951 defence agreement that already allows US troops to operate in Greenland, and the agreement still requires approval through Danish parliamentary procedures before it can enter force.
