Donald Trump renewed his suggestion that Greenland should be controlled by the United States as he arrived for a NATO summit, drawing fresh criticism from European leaders who say the Arctic island—self-governing but part of the Kingdom of Denmark—belongs to its people.

The comments followed diplomatic friction involving Trump’s wider demands about Greenland and security in the Arctic. Denmark’s prime minister, Mette Frederiksen, and Greenland’s leadership have rejected any idea of a U.S. takeover and said decisions about Greenland’s future can only be made by Denmark and Greenland.

In response to Trump’s stance, a group of European leaders—including France, Germany, Italy, Poland, Spain, the UK, and Denmark—issued a statement reaffirming Greenland’s strategic importance but emphasizing that sovereignty is not negotiable. Canadian Prime Minister Mark Carney also said Canada supports Greenland and Denmark’s right to determine Greenland’s future.

Trump has argued that controlling Greenland is important for NATO-linked security, pointing to Arctic risks and threats. The renewed remarks came as Trump sought to position the United States as central to Arctic defense planning, while European governments emphasized alliance unity and Denmark’s authority over the territory.
