First I've seen of the fireside chats: a bit of a sensationalist title, provides a high level overview and certainly a more modern interpretation of events than many of the books written within 20 years of the end of hostilities.
Nothing shocking though, if you have read more than Wikipedia summaries of the different campaigns... I do like how they bring home the fact that it was more than a war gaming exercise on a sterile bit of desert: from the West coast to the Eastern horn, North Africa is incredibly diverse in population, climate, topology and economy, all suffering.
They could have reminded us that in essence, it was a European war being executed in European colonies on the African continent. Then Africa was left with the mess.
