Delcy Rodríguez, the acting president of Venezuela, conducts the nation’s business out of the Miraflores Palace, a 19th century neoclassical mansion in the heart of Caracas. Gilded portraits of Simón Bolívar and Hugo Chávez gaze down on the ornate halls. Birds chirp in the manicured gardens. An unusually tight security detail shadows Rodríguez’s every step. The caution is understandable: Not long ago, the U.S. sent a Delta Force unit into her predecessor’s residence on a nearby military base to seize the man she had served for years.
