Force Ratios (the old 3-to-1 rule)

From what I can tell, interwar German facination with Liddell-Hart's writings have pretty much been debunked as a post-war sleight of hand by Sir Basil while working with the German generals on their memoirs.

Yes, John Mearsheimer wrote the book on that, I think it was called Liddell Hart and the Weight of History.

Liddell Hart wrote and said some interesting things, but he was also all over the map. He, along with many others, drew the wrong lessons from the Spanish Civil War, and was opposed to a continental commitment until pretty late in the game.
