Shortly after midnight on 18th January, one of the two men who claims to be the president of Venezuela snuck by foot across the little-patrolled border into Colombia. The crossing, most often used by migrants and smugglers, can be made in minutes. At the other side of the frontier, Colombian intelligence officials were waiting for Juan Guaidó. Greeting him formally as “Señor Presidente,” they escorted him on to a government plane for the short flight to Bogotá.
