While we've been obsessing about the UK election, the world has been turning - this week we broaden our horizons to discuss the latest developments in Saudi Arabia, Qatar, Iran and Syria. What do recent changes in Saudi politics mean for the stability of the region? Is the Trump administration making a bad situation worse? Plus we ask the WWI question: are there fault-lines here that remind us of 1914 and a world on the brink of war? We also talk to Helen about her new book: Oil and the Western Economic Crisis. It all comes back to oil. With Helen Thompson, Glen Rangwala and Aaron Rapport.
