The European response: what happened and who signed

The heads of state and government of France, Germany, Italy, Poland, Spain, the United Kingdom and Denmark issued a joint statement in support of Denmark after statements by the U.S. president about a possible interest in Greenland. The document, including a version published by the German government, emphasizes that Greenland belongs to its people, and issues concerning the island should be decided only between the self-governing territory and Denmark.

What the statement says

The partners recalled the need for collective security in the Arctic in coordination with NATO allies, including the United States, and the importance of upholding international law — in particular the principles of sovereignty and territorial integrity.

"These are universal principles, and we will not stop defending them. The United States is an important partner in that endeavor as a NATO ally and within the scope of the 1951 defense agreement between the Kingdom of Denmark and the United States."

Context and sources

The signal from Brussels and European capitals was a response to a series of public statements that drew international media attention. Unnamed American officials told The Economist about possible U.S. talks with Greenland — information that Europe decided to dispel with an official consolidated position.

"When someone repeatedly talks about wanting to acquire another territory, it must be taken seriously; a U.S. military attack, in particular, would mean the end of NATO."

— Mette Frederiksen, Prime Minister of Denmark

Why this matters

First, it is a reaffirmation of the principle of non-interference in domestic affairs and sovereignty, which underpins the modern post-World War II order. Second, it is a test of allies' ability to act in a coordinated way: the joint statement shows that Europe is ready to close information and diplomatic vacuums that might be exploited to undermine international norms.

Third, for Ukraine this episode is a reminder of the importance of collective guarantees and that the principles of territorial integrity are not an abstraction, but a practical tool for defending statehood.

What next

The immediate next steps are to monitor bilateral contacts between Denmark, Greenland and the United States, as well as Brussels' reaction to any informal initiatives. The joint statement does not close the issue completely, but it forces actors to operate within established rules — and that is key to preserving stability in the region.

Will international institutions continue to adhere to these rules when the interests of great powers stoke tensions? The answer depends on the willingness of allies to transform declarations into concrete political and legal measures.
