The Economist’s John Prideaux (US editor), James Bennet (Senior editor), James Astill (Washington bureau chief and Lexington columnist) and Sophie Pedder (Paris Bureau Chief) discuss how 9/11 changed America and how the response of successive administrations to the tragedy has affected its standing in the world. You can watch the conversation in full below.

The 9/11 attacks and the fear of further terrorism led to US military interventions abroad. The war in Afghanistan cost the country more than $2trn as well as the lives of thousands of its troops, and has ended in defeat. Osama bin Laden, the mastermind of the September 11th attacks, is dead, but violent jihadist Islamism has not been defeated, and indeed is spreading.
