Mike Williams presents a special extended edition of The Why Factor on patriotism. He asks what motivates people to serve their country and how this loyalty can be fostered, manufactured and manipulated. Mike investigates the power of patriotism from World War One to the present day – exploring flags and anthems, borders and boundaries, King and Country, God and Empire, and the truths and the myths of the modern nation state. What would you be willing to fight and die for?
