Palestinian refugees

Palestinian refugees are people who lost both their homes and means of livelihood as a result of the 1948 Arab–Israeli conflict and the 1967 Six-Day War. The number of Palestinians who were expelled or fled from Israel was estimated at 711,000 in 1949. The descendants of all refugees (not just Palestinian refugees) are considered by the UN to also be refugees. As of 2010 there are 4.7 million Palestinian refugees. Between 350,000 and 400,000 Palestinians were displaced during the 1967 Arab–Israeli war. A third of the refugees live in recognized refugee camps in Jordan, Lebanon, Syria, the West Bank and the Gaza Strip. The remainder live in and around the cities and towns of these host countries. Most Palestinian refugees were born outside Israel and are not allowed to live in any part of historic Palestine.

Israel has since 1948 prevented the return of Palestinian refugees and refused any settlement permitting their return except in limited cases. On the basis of the Universal Declaration of Human Rights and UN General Assembly Resolution 194, Palestinians claim the right of refugees to return to the lands, homes and villages where they lived before being driven into exile in 1948 and 1967. Arafat himself repeatedly assured his American and Israeli interlocutors at Camp David that he primarily sought the principle of the right of return to be accepted, rather than the full right of return, in practice.

Palestinian and international authors have justified the right of return of the Palestinian refugees on several grounds: Several scholars included in the broader New Historians argue that the Palestinian refugees fled or were chased out or expelled by the actions of the Haganah, Lehi and Irgun, Zionist paramilitary groups. A number have also characterized this as an ethnic cleansing. The New Historians cite indications of Arab leaders' desire for the Palestinian Arab population to stay put.

The Israeli Law of Return that grants citizenship to people of Jewish descent has been described as discriminatory against other ethnic groups, especially Palestinians that cannot apply for such citizenship under the law of return, to the territory which they were expelled from or fled during the course of the 1948 war.

According to the UN Resolution 194, adopted in 1948, "the refugees wishing to return to their homes and live at peace with their neighbours should be permitted to do so at the earliest practicable date, and that compensation should be paid for the property of those choosing not to return and for loss of or damage to property which, under principles of international law or in equity, should be made good by the Governments or authorities responsible." UN Resolution 3236 "reaffirms also the inalienable right of the Palestinians to return to their homes and property from which they have been displaced and uprooted, and calls for their return". Resolution 242 from the UN affirms the necessity for "achieving a just settlement of the refugee problem"; however, Resolution 242 does not specify that the "just settlement" must or should be in the form of a literal Palestinian right of return.

Historically, there has been debate over the relative impact of the causes of the 1948 Palestinian exodus, although there is a wide consensus that violent expulsions by Zionist and Israeli forces were the main factor. Other factors include psychological warfare and Arab sense of vulnerability. Notably, historian Benny Morris states that most of Palestine's 700,000 refugees fled because of the "flail of war" and expected to return home shortly after a successful Arab invasion. He documents instances in which Arab leaders advised the evacuation of entire communities as happened in Haifa although recognizes that these were isolated events. In his later work, Morris considers the displacement the result of a national conflict initiated by the Arabs themselves. In a 2004 interview with Haaretz, he described the exodus as largely resulting from an atmosphere of transfer that was promoted by Ben-Gurion and understood by the military leadership. He also claimed that there "are circumstances in history that justify ethnic cleansing". He has been criticized by political scientist Norman Finkelstein for having seemingly changed his views for political, rather than historical, reasons.

Although Israel accepts the right of the Palestinian Diaspora to return into a new Palestinian state, Israel insists that the return of this population into the current state of Israel would threaten the stability of the Jewish state; an influx of Palestinian refugees would lead to the end of the state of Israel as a Jewish state since a demographic majority of Jews would not be maintained.
