montelatici, et al,
Of the 1.7M people of the population living in the country last year (2014), 75% (1.2+M) are considered "Sabras" - native-born Israeli.
• Of the Palestinian Refugees, in the occupied Palestinian territory (oPt), fighting over the "right-of-return:" HOW ANY WERE BORN IN ISRAEL?
• How many of these claimants --- were actually deported or forcible transferred from a previous residence in Israel? (It certainly cannot be as many as there are native Israelis. Why should they be threatened by alien Arabs?)
[Why should the native Palestinians leave their ancestral home to European the offspring of the European newcomers?
(COMMENT)
The question you ask is nebulous. We must narrow it down and be more specific.
• The legality of an action taken in 1918 through 1922, is base on what the law was in 1918 through 1922. To discuss what the law is today and attempt to apply it to the conditions of a near century ago is totally impossible.
• Similarly, the legality of an action taken in 1948 or 1967, must be evaluated in terms of the law and the customary action of nations in the 1948 and 1967 era. You cannot apply more recent laws to events or actions taken a half-century ago.
And it is even more difficult to evaluate the application of customary laws when, the indigenous population, no matter how long they have lived on the territory, never the had sovereignty over the territory.
(REMEMBER)
No indigenous citizen of the territory, that included Palestine, ever exercised sovereignty authority over that territory
(not in the second millennium). It could be argued that while there were several period of Arab Rule in the First Millennium, those rules came from all over the region; but were not indigenous. Even Saladin, First Grand Sultan of Egypt and Syria --- Liberator of Jerusalem, was a Kurd from Tikrit. And again, the Ismaili Islamic Caliphate was a Shi'ite sect associated with the Fatimah following
(descent from Fatima bin Muhammad, daughter of Islamic prophet PBUH) were from the Hejaz.
