For this week's Sunday Debate, we're dipping back into the archive to 2014, when we gathered a panel of expert historians to debate whether Britain was right to fight in the First World War, a tragedy that laid the foundations for decades of destructive upheaval and violence across Europe. To debate the issue, we invited leading historians Margaret MacMillan, Max Hastings, John Charmley and Dominic Sandbrook to an event hosted by journalist, columnist and national security expert, Edward Lucas.  We’d love to hear your feedback and what you think we should talk about next, who we should have on and what our future debates should be about.
