I was re-reading Alistair Horne’s book To Loose a Battle this past weekend. When on June the 14th, Paul Reynaud made his plea to President Roosevelt for intervention. Needless to say, there was no chance of this ever happening. It did however make me wonder, if, after 1918 the US had decided to maintain a more robust peacetime army. To have been considered at a minimum, a credible threat to both European and Asian powers. So how large would the active army’s numbers have needed to have been? I’m talking about manpower, armor, army air corps, artillery, plus reserve supplies and reserve numbers of men?
