Jared Diamond explores how countries survive national crises. The Pulitzer Prize-winning author and polymath talks to Andrew Marr about the process seven countries went through at moments of huge upheaval – from Japan and Finland to Australia and Chile. Using the lessons learnt in overcoming personal trauma, Diamond charts the painful process of self-appraisal, selective change and flexibility needed to move forward.

Britain is facing its own national crisis, with the public and political parties divided over Brexit, political leadership and the way to move forward. Professor David Runciman and the Associate Director at the IEA Kate Andrews put Jared Diamond’s thesis to the test. They explore how far we can learn from past disasters and whether there are core national values that could help to unite the country. And, as the Conservative leadership contest begins and President Trump arrives in the UK, they discuss the limits to power and the myth of the strong leader.
