We discuss Donald Trump’s latest foray into foreign policy (1:01) – in taking the US out of the Iran nuclear deal. Is it worthy of a Nobel peace prize, or the act of a maniac?

We also talk about the young Londoners who regularly take cocaine, despite the drug’s violent supply chain (13:20), and ask, are emojis ruining children’s abilities to communicate (22:04)?

With Christopher de Bellaigue, Dr Roham Alvandi, Alastair Thomas, Dr Adam Winstock, Lara Prendergast, and Professor Vyv Evans.

Presented by Isabel Hardman.
