MUNICH (AP) — At the Munich Security Conference on Saturday, U.S. Secretary of State Marco Rubio underscored the United States' steadfast commitment to preserving the trans-Atlantic alliance, declaring it will always be a child of Europe. His remarks come at a time when tensions have surfaced between Washington and its European allies, echoing concerns raised a year ago. Rubio asserted that the post-Cold War euphoria had fostered a dangerous illusion of victory, now jeopardizing the very institutions that defeated the Nazi regime and the Soviet Union.
