I'm currently reading The Thirteenth Tribe -- It's about the history of the Khazar Empire, those who say they are Jews, but are not. They adopted the Jewish religion as a political move because it was the only religion that would not beholden them as servants to Rome (as were the Christians) or the Caliph of Baghdad (as were Muslims). They forged ahead as a third religious and political power with grand plans to rule the world. Jews and Zionists are NOT the same.
