All eyes are on Vienna as delegations from the United States, Germany, France, the UK, Russia and China meet with Iranian officials in a final push to secure a comprehensive agreement over Iran's nuclear program. They have until July 20 to come to terms. 
The negotiations are complex and the issues vexing. But one thing is certain: if an agreement is struck it could change international relations in the entire Middle East and even the world. Here to take us inside the negotiations is veteran journalist Laura Rozen. She sets the scene for what to expect in Vienna in the coming days. I also speak with Daryl Kimball of the Arms Control Association who breaks down the wonky key points of negotiation in an easily digestible way. 
I think you'll enjoy this episode. This is a hugely significant moment for Obama's foreign policy legacy, the Middle East, and the cause of non-proliferation. Have a listen.
