Trump pulls the US out of Iran nuclear deal

Donald Trump strikes again. After pulling out of the Paris agreement on climate change last June, the US president announced the country will no longer be part of the deal on Iran's nuclear weapon concluded by his predecessor Barack Obama in July 2015. 

Producer Lisa Boudet reports on the president's decision, and what it means for both Iran and the rest of the signatories, as well as for the future of diplomacy and world stability.
