US Secretary of State Marco Rubio faced sharp questioning from senators over presidential war powers, NATO unity, and America’s global role, as lawmakers debated the legality and long-term consequences of US actions in Venezuela. Rubio defended the operation that led to the arrest of Nicolas Maduro, arguing it did not amount to war. “NATO needs to be reimagined,” Rubio said, clarifying that its “capabilities have to be reimagined,” not its purpose. “Without the United States, there is no NATO,” he said. “The President, in his speech in Davos, made very clear that the United States was not going to use force or military force in Greenland,” he said.
