288 | War: What Is it Good For?

We talk to the historian Margaret MacMillan about the changing character of war, from the ancient world to the twenty-first century. Do we still understand the risks? Where are the conflicts of the future likely to break out? And how can we reconcile the terrible destructiveness of war with its capacity to bring about positive change? Plus we talk about why war produces so much great art.

276 | Jill Lepore on the Destructive Power of Tech

David talks to the American historian Jill Lepore about the damage new technology can do to democracy, from the 1960s to the present. Who first tried to manipulate the minds of the electorate? Where did the money come from? What happened when the same technology was applied to fighting the Vietnam War? Plus we discuss US presidential elections from 1960 to 2020: do the machines really decide who is going to win, and if he does win this time, what might Joe Biden be able to do about it?

159 | David King on Climate Repair

An extra episode in our climate season: we talk to Sir David King, former Chief Scientific Advisor to the British government, about what's now known about the scale of the threat and the urgency of the need for action. What has happened since the Paris agreement? What is the Chinese government most afraid of? What is the meaning of Extinction Rebellion? And is it time to start talking about refreezing the poles to repair the damage already done?
