Angie Zelter is on her way to Loch Goil in Scotland. It’s a beautiful summer’s day, and her friends have packed a picnic. But that’s not the real reason they’re there. Angie has an urgent message to deliver to the world about nuclear weapons. And she’s going to deliver it through an act of destruction.

In this episode, Matthew Syed looks at the danger that nuclear weapons pose, even if nations never use them in a deliberate act of war. He hears about the moments we came within a hair’s breadth of disaster through misunderstanding, negligence, accident and even a blackbrown bear.

It’s simple - the more weapons there are in the world, the more risk increases. But how to deal with this problem throws up complex solutions and viewpoints.

Some would like the total eradication of nuclear weapons, arguing that disarmament across the world is the only way to avoid catastrophic risk. But others worry about disrupting the delicate balance of nuclear deterrence. As Matthew hears, history shows us that scaling back the numbers is possible - even at the height of the Cold War. He asks whether the possibilities for non-proliferation and scaling back through treaties and verification could be a way forward today.
