I should have done. I've been writing about it for four years now, with War on Wheels on WW2 and Ordnance on Equipping the Army for the Great War. Iron, Steel and Coal are the sinews of war. By putting the industries of the former waring nations together, the risk of war was massively reduced. So too the capacity for building a lasting and prosperous peace.
I am indebted to Bill Hayes on Facebook for drawing my attention to a short video, by historian David Reynolds, that explains it all.
My researches took me to the mid nineteenth century when Britain, France and Germany had each developed massive arms industries which only grew more powerful through the demands made on them by two World Wars.
It also reminded me of a piece I wrote eighteen months ago and which I had forgotten had been published in the Lincolnshire Echo.
May our leaders watch and learn.
