Who the establishment of state Israel in 1948 about how many native Palestinians moved into neighboring Arab countries?

It is not correct to state that "native Palestinians moved into neighboring Arab countries" or "fled" following the establishment of the state of Israel in 1948. The displacement and dispossession of Palestinians during that time is commonly known as the "Nakba" or the "Catastrophe." Here's a more accurate explanation:

The Palestinian Exodus (Nakba):

- The establishment of the state of Israel in 1948 resulted in the displacement of a large number of Palestinians from their homes and lands.

- The United Nations estimated that around 700,000 Palestinians became refugees during that time.

- The majority of these displaced Palestinians sought refuge in neighboring Arab countries, such as Jordan, Lebanon, Syria, and the Gaza Strip (which was under Egyptian control).

- The Arab countries that accepted Palestinian refugees set up camps to provide shelter and basic necessities. These camps eventually turned into semi-permanent settlements where many Palestinian refugees still reside today.

- The displacement of Palestinians was the result of several factors, including armed conflict, forced expulsions, and the destruction of Palestinian villages and towns.

It is important to note that the displacement of Palestinians during the Nakba was not simply a voluntary movement, but rather a result of political and military factors, including the Arab-Israeli conflict and the Israeli military operations during that period.
