Regardless of whether Purim was a silly myth or not, there was no "Israeli-Arab" conflict of the sort that you propose.

No, the interesting thing is that the majority of anti-Jewish sentiment, prior to the latter half of the Twentieth Century, came from WHITE CHRISTIANS IN EUROPE. Jews were protected in al-Andalus, they were protected in Jerusalem under the Muslims, they were protected by the Sultan of the Ottoman Empire and they were protected by the Shahs of Persia.

Jews lived in peace in Baghdad, and Basra, and Tehran, and Shiraz, and Damascus, and the cities of Morocco, and Jerusalem, and Granada.

Yes, they had to pay taxes as dhimmis. However, they weren't murdered on a regular basis the way they were in Europe. They weren't deported en masse like they were from Spain and England. They weren't burned and attacked like they were in Germany, and France, and Italy. They weren't systematically deprived of any means of working the land, attending institutions of higher education or advancing themselves like they were all over Europe. They weren't slaughtered in pogroms, they weren't killed in death camps and they weren't forced to live in ghettos or shtetls.

Up until the time that militant Zionist settlers arrived in British Mandate Palestine in the 20th Century, there was really virtually no Jew-Arab hostility, and there hadn't been since the establishment of Islam. Some issues can be raised about the last days of Muslim Spain and the Nineteenth Century in the Ottoman Empire, but the problem there is more one of a degeneration of public order generally.

As a result, the problem is, really, a new one.
