War of the World

I recently read War of the World, 2006, by Niall Ferguson (NF), a Harvard history professor. NF's thesis is: the 20th Century's various wars were part of a worldwide power shift from the West to the East. NF's thesis is provocative to say the least. His book is full of obscure historical facts I had not encountered before and is worth reading. NF is vaguely reminiscent of Oswald Spengler who wrote The Decline of the West, 1922.
