Copenhagen, January 6, 2026 – Danish Prime Minister Mette Frederiksen has warned that any attempt by the United States to seize Greenland would spell the end of the NATO alliance, following heightened tensions after the US military operation in Venezuela.

Frederiksen’s statement comes after US President Donald Trump renewed calls to bring Greenland, a semi-autonomous territory of Denmark, under direct US control. Trump has not ruled out using military force, fueling concerns in Copenhagen and Nuuk about the stability of the alliance.

Prime Minister’s Warning

“If the United States chooses to attack another NATO country militarily, then everything stops,” Frederiksen told Danish broadcaster TV2. “That includes NATO itself and the security it has provided since the end of the Second World War.”

The warning echoes broader alarm over Washington’s recent abduction of Venezuelan President Nicolas Maduro and the potential for similar unilateral military actions abroad.

Greenland Leaders Respond

Greenland’s Prime Minister Jens-Frederik Nielsen emphasized that the island is not for sale and called Trump’s threats and social media posts “disrespectful.” He stressed that mutual respect and international law are essential in relations between nations.

“There is neither reason for panic nor for concern,” Nielsen said. “The situation is not such that the United States can simply conquer Greenland.”

The controversy escalated when Katie Miller, wife of Trump’s deputy chief of staff, posted a picture of Greenland in US flag colors on X with the word “SOON,” prompting strong reactions from Greenlandic officials.

Strategic Importance

Greenland’s location between Europe and North America makes it a critical site for US missile defense systems, and its mineral resources are valuable for reducing reliance on Chinese exports. Trump defended his interest, stating, “We need Greenland from the standpoint of national security, and Denmark is not going to be able to do it.”

Despite the rhetoric, Nielsen urged calm and emphasized ongoing cooperation with the US, noting that there is no immediate threat of a takeover.
