US President Donald Trump has announced an agreement with Denmark and Greenland covering security and defence, according to Público. The Portuguese outlet reported the announcement on Saturday, 19 September 2026.
Coverage of the deal varied across outlets. CartaCapital reported that Trump described it as an arrangement for permanent control of Greenland's "security." G1 framed the agreement around US control of the territory and raised the question of what role China played in the negotiations.
Denmark and Greenland responded to those characterisations. According to UOL Notícias, both stated that the agreement with the United States will not involve any transfer of sovereignty. Opera Mundi reported that the deal was signed after earlier US threats to annex the territory.
The accounts differ on how much control the United States gains. Trump's own description, as reported by CartaCapital, points to a lasting American role in Greenland's security, while the Danish and Greenlandic position reported by UOL Notícias stresses that sovereignty remains unchanged. Público's headline frames the outcome as a security and defence agreement between the three parties.
The full terms of the agreement have not been detailed in the reporting summarised here.
What to watch next: whether Washington, Copenhagen and Nuuk publish the specific terms of the agreement, and how they reconcile the differing descriptions of what the US role in Greenland will be.
