The World Wars were total. Entire populations were mobilised at home and away. Part of our fascination with them lies in the fact that our modern wars look entirely different. They are fought by volunteer armies with smart, modern technology. William Arkin is a bestselling author, military expert, and award-winning journalist. He is also a former intelligence analyst. William came onto the podcast to talk to James about how the battlefield has developed since the end of the Second World War. He traces the fall of the ‘front line’ and the development of new weapons which have brought an end to the need for feet on the ground. This is a great insight into the workings of war and the changes in public attitudes towards it.
