"What legal documents or deeds give Palestinians their claimed rights?"
Fifteen hundreds years of habitation is a legal document in the minds of all decent and moral men, all except the perverse Zionist and fundamentalist Jewish mentality.
As for the modern Jews, they have no legal document. Modern Jews are composed of Kahazars (Ashkenazim) which were converted to talmudic Judaism in the ninth centur AD, black Ethiopians, white Europeans Jews, dark Arabic Jews, Oriental Jews, etc. etc. In other words, the modern Jew is not genetically the heirs of the Hebrews in the Bible. Zionist stake their claims to Palestine on a false deed. Since modern Jews are not the ancient Hebrew, the Zionist claim to the land is false.
Zionists needed to justify their colonization of Palestine so they attempted to use an invalid Hebrew and Biblical claim to land. |
