Can the Taliban be stopped from retaking Afghanistan?

With the Taliban gaining territory following the exit of foreign forces from Afghanistan, we ask: can they retake the country? An MP from the city of Kandahar gives us his views, and the BBC's Lyse Doucet looks at the prospects for a political solution. Also in the programme: we hear from an academic who joined the resistance in the war-torn Ethiopian region of Tigray, and Frederick Forsyth, the author of the seminal thriller The Day of the Jackal.
