Why Maduro is blocking Venezuela-bound humanitarian aid when so many people in his country need it

Relations between the United States and Venezuela have been strained since the late Hugo Chávez rose to power two decades ago. They got worse when the Trump administration recognized opposition leader Juan Guaidó as the South American country’s president instead of Chávez successor Nicolás Maduro in January 2019.
These tensions could become a full-blown crisis, as has become clear along the Venezuela-Colombia border, where Maduro is blocking the entry of U.S. humanitarian aid. The United States says it is sending US$20 million in food and medical supplies to alleviate suffering at a time when Venezuelans are experiencing widespread malnutrition and lack access to health care. Maduro contends that these shipments are a plot to meddle in his country’s internal affairs – a Trojan horse courtesy of Uncle Sam to undermine Venezuelan democracy.
