How long US forces could hold territory

President Trump has posted on social media another warning that he would, in his words, 'obliterate' Kharg island and Iran's power plants, if the Strait of Hormuz is not immediately reopened to allow oil and gas tankers to travel freely.

Also on the programme: how are countries around the world responding to the price of oil reaching $116 a barrel? And paintings by Renoir, Cezanne and Matisse have been stolen from a museum in Italy. Is there's even a market for this type of stolen art?
