Jews have been persecuted by Arab Muslims since the 7th century and under Sharia law they were second class citizens, subject to degrading and humiliating laws and special taxes right up until the British took over and the Arabs insisted the Jews remain second class citizens, and of course, the European Jews refused, hence the onslaught of Arab terrorism against the Jews.
There was no invasion, just a wave of immigration, but because the immigrants were Jews, the Arabs found it to be intolerable. Both the Ottoman Turks and the British kept excellent records and there is no mention of any land theft by Jews in any of them; there is, however, detailed records of purchases of land from wealthy land owning families. Before the Arab nations declared a war of extermination against the Jews in 1948, casualties from the skirmishes between Arabs and Jews were very low.
So there was no invasion, no land theft, no thousands of casualties and no oppression of any Arabs by the Jews who emigrated to Palestine. The persecution of Jews has been a core value of Muslim culture, law and religion since the 7th century and is the single cause of all the conflict in Palestine.
