The theory in Europe that there is a Jewish conspiracy, is old to ancient, from earlier times on up through the activities of the third reich, and I guess still even today. It all started when people that were unhappy with their own meager lot, looked around for those that stressed such things as education, medicine, and the arts, for someone to blame. Leaders let it happen to take the heat off themselves as the real root of the problems, sometimes organised the hate and attacks. People still wanting to believe that theory are just plain dumb.
