President Trump faces a crucial test of his foreign policy and his resolve over Venezuela. His administration has made absolutely clear that the United States no longer considers Nicolas Maduro to be president, publicly backing Juan Guaido, the head of Venezuela’s National Assembly, as the country’s interim leader. Trump has gone so far as to urge the Venezuelan military not to follow Maduro’s orders. These declarations are much stronger than the “red line” Barack Obama drew around Syrian president Bashar Assad.
