US President Donald Trump has threatened to destroy Iran's Kharg Island unless Tehran accepts a peace deal, but an expert says empirical evidence suggests otherwise.

US President Donald Trump threatened on March 30 to destroy Iran's crude export hub of Kharg Island, along with its oil wells and power plants, unless Tehran quickly accepted a peace deal. He also claimed that the United States was in 'serious discussions' with 'a more reasonable regime' in Tehran. 'While Trump points in one direction, empirical evidence seems to point the other way' says FRANCE 24's Douglas Herbert.
