Laws that control and restrict Jews become models for control and restrictions of other religious and ethnic groups. Catherine the Great limited where Jews could live. Prejudice expanded to officially sanctioned pogroms that sent many Jews emigrating to the West. The Soviet Union enforced brutal legal restrictions on Jews and ruthlessly expanded them to other minorities. The Dreyfus case in France at the end of the 19th century provoked international condemnation and severely weakened the French military; its effects are felt today. Germany has yet to recover the talents of the Jews it killed or expelled under The Third Reich, including 20 Nobel Prize scientists.
The impact of anti-Semitism on the Arabs in the Middle East is only now getting the attention it deserves. Jews under the Ottoman Turks in the 15th and 16th centuries were welcomed for their advanced knowledge of spinning, weaving and dying of textiles. Their knowledge of European languages enabled Muslims to employ them as diplomats. Modern Islam merely blames them for everything they imagine going wrong.
Paul Johnson notes that Arabs have not only wasted trillions of dollars of oil revenues, blowing much of the money on armaments, but they have neither consolidated nor modernized their law nor copied any of the techniques of land management the Jews have used to make the desert bloom. Playing the victim and blaming the Jews for everything that goes wrong galvanizes hatred, but it doesn't do anything to make Arab life livable.
"The Protocols of the Learned Elders of Zion," the crude Czarist forgery that blames Jewish conspiracies for everything bad, is a perennial bestseller in the Arab world and taught as fact in the schools. The book, laughed at in the West, became a Cairo television series widely popular in the Islamic world.
Imagine how different things could have been if the Arabs had cooperated with Jews early in the 20th century. Imagine a Jewish-Arab collaboration to build real schools, teaching hospitals and great universities. Imagine what might have been if they had worked the land together, exchanging techniques of cultivation. Imagine what might have been if they had cooperated to develop joint social services for the needy of both peoples. Imagine.
