The White House confirmed acquiring Greenland is a national security priority, with all options on the table but preferring diplomacy and purchase. Press secretary Karoline Leavitt emphasized options like buying Greenland or a Compact of Free Association. Secretary of State Marco Rubio briefed lawmakers, downplaying invasion but affirming pursuit of acquisition, and plans to meet Danish officials next week. European allies issued statements supporting Denmark and Greenland's sovereignty, warning forcible takeover could endanger NATO. Danish PM Mette Frederiksen reiterated Greenland is not for sale and Trump should be taken seriously. Greenlandic leaders and locals expressed fear and rejection of U.S. ambitions. U.S. congressional figures, including Rand Paul, opposed military options. US forces seized sanctioned oil tankers in the North Atlantic, unrelated to Greenland but amid heightened tensions.
