Nuclear weapons and mutually assured destruction are associated with the Cold War but today more countries have the bomb than ever. An American president has the power to unilaterally start a nuclear war. In South Asia, India and Pakistan face off across a volatile border, both countries hold nuclear arsenals primed and ready to fire. Elsewhere, rogue-nation North Korea edges closer to nuclear capability, and a nuclear armed Israel sees its very existence threatened by Iran. So how safe are we from nuclear destruction? Join Owen Bennett Jones and his guests on Newshour Extra as this week they discuss the nature of the threats we face from nuclear weapons: how secure are global stockpiles, and what is the likelihood that any one of the many thousands of nuclear warheads across the globe could be launched intentionally or by accident?
