In Europe, Trump aide snubs host on Greenland question, threatens NATO allies| Lutnick| USA| Denmark

U.S. Commerce Secretary Howard Lutnick sidestepped questions on Greenland at the World Economic Forum in Davos as tensions escalated between Washington and Europe over Donald Trump’s threats to take over the Arctic territory. Lutnick said Greenland was a national security issue being handled by U.S. officials, while warning Europe that any tariff retaliation would trigger a tit-for-tat response. The remarks came as Trump threatened new tariffs on countries deploying troops to Greenland, prompting European warnings of a dangerous downward spiral. The row has deepened transatlantic tensions, with Trump insisting Greenland is vital for U.S. security.
