European officials leaned towards negotiating with U.S. President Donald Trump over his Greenland security threats rather than retaliating, according to a New York Times article shared by OpenSourceZone on X during the 59-minute period from 1:46 a.m. to 2:45 a.m. UTC on January 19, 2026. This stance follows EU leaders coalescing around a negotiation strategy on January 18, as reported in the same New York Times article cited in earlier coverage, amid Trump's tariff threats on NATO allies pursuing Greenland security. The development builds on Danish defense documents revealed on January 18 showing U.S. requests for Greenland military site information without Copenhagen's involvement, per Berlingske, and NATO activities including Canadian considerations for troop deployments and multinational exercises in Greenland meeting Joint Arctic Command commander Major General Søren Andersen, according to The Globe and Mail and Danish armed forces Forsvaret. UK Prime Minister Keir Starmer addressed the tariff threats in an afternoon call with Trump on January 18, per a Downing Street readout, while the UK's Commando Helicopter Force ramped up Operation Clockwork in northern Norway for Exercise Cold Response 2026, as announced by Joint Force Command Norfolk.
