Venezuela's President Nicolas Maduro has issued a chilling warning to U.S. President Donald Trump amid rising tensions in the Caribbean. Maduro vowed to defend his nation against what he called U.S. “aggression,” following a deadly strike on a Venezuelan boat. He branded U.S. Secretary of State Marco Rubio the “lord of death and war,” blasting his rhetoric on Latin American cartels. Maduro said Venezuela would exercise its right to defend itself as Trump hinted at new military action.
