My Jewish sources have said that a Jew is a Jew. There is no teasing out by race. The Jews brought Ethiopians and those from Northern Africa and Yemen into Israel. Your information focuses on specific points of time and populations. That information may be of interest to anthropologists and chroniclers and demographers, but all my research seems to focus on the fact that the Balfour Declaration after WWI says that Britain was to give lands to both Jew and Arab. Bottom line — Arabs just flat out don’t like having anybody but other Arabs living in their neighborhood. It is troubling that there have been so many Arabs and Muslims killed and displaced by other Arabs/Muslims. How sad. This reminds me of a couple of sayings — 1) With friends like you, who needs enemies? 2) Why talk about the sliver in my eye when you have a log in your own. Considering how ineffective the Arab League has been, how corrupt the strongmen leadership has been in the Arab world, it seems to me that the Palestinians should realize that they should not have left their land in 1948 to allow the Syrians, Egyptians, and Jordanians to “push the Jews into the sea”. The Palestinians made a bad choice.
