U.S. Attack on Greenland Would End NATO, Diplomats Warn

An alleged U.S. move against Greenland could trigger NATO’s collapse, diplomats say, as Washington debates annexation, alliance rules, and growing geopolitical pressure.

A hypothetical U.S. attack on Greenland — an autonomous territory within the Kingdom of Denmark — would spell the end of NATO, an unnamed alliance diplomat told Politico.

According to the source, a direct strike by the bloc’s largest and most heavily armed member against another NATO participant would be without precedent in the organization’s history. Such a scenario, the diplomat argued, is simply incompatible with the alliance’s foundations.

The NATO founding treaty of 1949 contains no provisions that would allow one member state to attack another. An assault of this kind, the source said, would amount to the alliance’s collapse.

Similar warnings had been voiced earlier by European Commissioner for Defence Andrius Kubilius, who pointed out that any attempt by the United States to annex Greenland would dismantle the North Atlantic Alliance as it currently exists.

The debate intensified on December 12, when Republican Congressman Randy Fine introduced a bill in the U. S. Congress proposing Greenland’s «accession» and the granting of U.S. statehood. Fine framed the initiative as a response to what he described as a growing threat from Beijing and Moscow. Under the proposal, if it were to pass, the White House — led by President Donald Trump — would be authorized to take what the bill calls «necessary measures» to annex or otherwise acquire the island.
