Trump's push to acquire Greenland creates a major crisis for the NATO alliance

President Donald Trump has renewed his interest in the United States acquiring Greenland, suggesting NATO should lead the process. He has argued that having Greenland under U.S. control would make the alliance 'far more formidable and effective' and has suggested he might leave NATO over the issue.

This has triggered a severe crisis within the alliance. European leaders and NATO officials are scrambling to respond, with some discussing deploying NATO forces to Greenland to deter the U.S. threat. A European commissioner stated that a U.S. military takeover would mean the end of NATO, and the prime minister of a member state said the threats make the alliance 'pointless'. NATO chief Jens Stoltenberg has said he cannot promise the U.S. will remain in the alliance.
