One of Americas leading commentators on current events in the Middle East, Iranian-born scholar Vali Nasr brilliantly dissects the political and theological antagonisms within Islam in this smart, clear and timely book (Broad-ranging and detailed, but still eminently readable.Arguably the best book on the market that provides a critical background to the emotionally charged events we have been witnessing in Iran, Iraq, Lebanon and beyond.The value of Mr. Nasrs account lies in the context he gives to todays headlines.Historically incisive, geographically broad-reaching, and brimming with illuminating anecdotes.
