Given the discussion of 'sunset' capabilities and the growing feeling in Brussels that the UK has a credibility problem inside NATO, Peter talks to Mungo Melvin (military historian and former soldier), about the dangers of thin-slicing history to draw conclusions about military capability requirements for the future. Mungo characterises the Western Way of Warfare as a dichotomy between what we want wars to looks like, and those we actually have to fight. A fascinating and illuminating conversation.
