President Nicolás Maduro of Venezuela threatened Saturday to seize idle factories in his country using a new emergency decree, moves that followed warnings by United States officials that economic chaos in the country had turned even his allies against him. “An idle plant is a plant the people will take,” local news outlets quoted Mr. Maduro as saying at a rally. “We will take all the actions necessary to activate production, which is being paralyzed by the bourgeoisie.” These threats came a day after Maduro said he would extend the state of emergency for another 60 days. This state of emergency came as a result of an economic crisis in Venezuela caused by low oil prices, lack of savings, and massive drought. Enormous lines for food and basic necessities, water shortages, and blackouts have become normal. The US is worried that this crisis will lead to violence on the streets of Venezuela as people struggle to survive, and officials are speculating that his removal from office is looming.
