Russian President Vladimir Putin called U.S. efforts to gain control of Greenland historically grounded and not to be dismissed, according to CNBC. Putin referenced past American offers to buy the mineral-rich Arctic territory. Putin said Trump’s plan is not preposterous, noting U.S. interest in Greenland dates back to the 1860s. He emphasized the Arctic’s growing global strategic importance, adding Russia will modernize its military infrastructure and respond to NATO's expanding presence. U.S. Vice President JD Vance is set to visit Greenland on Friday.
