It’s a little girl’s eighth birthday. She wakes to a sight that looks like the end of the world. A radioactive mushroom cloud rises 130,000 feet in the air. And the world wakes up to the devastating fallout of nuclear weapons.

In this new mini series from Sideways, writer and Times columnist Matthew Syed is calling for a nuclear awakening. Since the end of the Cold War, when relations between two of the world’s nuclear superpowers - the former USSR and the USA - seemed more rosy, Matthew argues that many of us have slipped into a kind of comfortable amnesia about the presence of these destroyers of worlds.

The wake up call came when President Vladimir Putin launched the invasion of Ukraine in February accompanied by veiled nuclear threats. It was a reminder of the mind bending fact that there are weapons in existence that are capable of eradicating our species.

Over four episodes, Matthew explores the intellectual and strategic frameworks birthed by the bomb and the tensions of the Cold War, which sought to contain the ultimate destructive force. From deterrence to disarmament and non-proliferation, these ideas all aim at one goal - protection from catastrophic nuclear use. Understanding their origins and complexities is urgently needed, Matthew argues.

Ultimately, Matthew will be asking if the actions of Putin in Ukraine call for a new intellectual framework to help make our world safe.
