Denmark and Greenland are scrambling diplomatically after U.S. President Donald Trump renewed threats over Greenland’s future, triggering alarm across Europe and within NATO. Copenhagen and Nuuk have sought urgent talks with Washington amid reports that Trump has asked for options ranging from a cash deal to potential military planning. European leaders, including the UK and France, have publicly pushed back, warning that any coercive move against Greenland would undermine NATO unity and international law.
