Episode Details

Since the start of the US-Israel war on Iran, The Global Story listeners have been contacting us with questions: about the causes of the war, the legality of it, and how other countries are responding. As Gulf states get drawn further into the conflict, might they send military reinforcement? And if the Iranian regime were to fall, could islamist groups such as Isis seize an opportunity to claim more power?

In today’s episode, we answer all of these and more, with BBC world affairs editor, John Simpson. Producers: Hannah Moore and Xandra Ellin Sound engineer: Travis Evans Senior news editor: China Collins
