Historically every great empire had Jews pulling the levers of power. Joseph in Egypt, Daniel in Babylon, Mordechai in Persia. The MO was established in Biblical times but continues to the modern era (Disraeli in Britain, Feinstein et al in the US Congress). The reason is simple. You can put your tribe in charge like Saddam Hussein al-Tikriti, or the Assad family in Syria. You can trust them to a point, but they will turn on you for your ambitious cousin. You put a hated minority in charge and they depend on your authority for protection.

The Jewish Mafia is powerful, but their power derives from them fronting for the incestuous Moabite-Sodomite bloodline families. Remember that when Christ stood before Pilate, the Sanhedrin's mob cried "His blood be upon us". From long experience, they knew that being the scapegoat is perilous but profitable.
