The Arabs attacked Israel and lost territory in wars they initiated. Europe's Jews were slaughtered for being Jews. The 11th century Rabbi Shlomo ben Yitzhak of Troyes ("Rashi")influenced by the massacre of Jews in the Rhineland by the Crusaders en route to the Holy Land reminds us "One day the nations of the world will tell the Jews, this land is ours; you stole it from us. And we will reply: the land belongs to God; He alone has the right to say who will live there. And He gave this land to us." (Quoted in Elie Wiesel, Rashi, 2009).
