Secretary of State Marco Rubio is suggesting the United States won't govern Venezuela other than enforcing an existing “oil quarantine” on the country. The turnaround Sunday comes after President Donald Trump announced a day earlier the U.S, would be running Venezuela following its ouster of President Nicolás Maduro. Rubio's statements on TV talk shows seemed designed to temper concerns about whether the assertive American action to achieve regime change might again produce a prolonged foreign intervention or failed attempt at nation-building. They stood in contrast to Trump’s broad but vague claims that the U.S. would at least temporarily “run” the oil-rich nation, comments that suggested some sort of governing structure under which Caracas would be controlled by Washington.
