What is the author's style in Genghis Khan and the Making of the Modern World by Jack Weatherford?

Jack Weatherford is the author of Genghis Khan and the Making of the Modern World and is the Dewitt Wallace Professor of Anthropology at Macalester College. He uses three major non-Western texts, including the Secret History of the Mongols. If Weatherford has a bias, it is his express desire to wholly rehabilitate the image of the Mongol Empire in the eyes of Western historians and the culture of the West generally.
