The 1970s are often remembered as a decade of protest, liberation, and social change — but they were also marked by violence, fear, and political extremism.

Today's guest Jason Burke is an international security correspondent for The Guardian and the author of The Revolutionists: The Story of the Extremists Who Hijacked the 1970s. In this book, he traces how radical groups across the globe turned revolutionary ideals into campaigns of terror — and how their actions reshaped politics, policing, and public life in ways we're still living with today.

This is a conversation about how extremism takes hold, how societies respond, and why the lessons of the 1970s matter now more than ever.
