Because Palestinians didn't exist prior to 1964 when Egypt created the PLO

Argument: Because they didn't exist prior to 1964 when Egypt created the PLO

Rebuttal: False. A Ben Gurion pointed out in the 1930's, the Palestinians were a nation. In 1905 during the Zionist Congress convention at Bessel (Switzerland) a Palestinian Jew, Yitzhak Epstein 1862-1943, delivered a lecture about the "Arab question" :

"...There is in our beloved land an entire nation, which has occupied it for hundreds of years and has never thought to leave it. . . . "

Argument: Aside from the 1930's aerial photos of Jerusalem, proving the non-existence of "east" Jerusalem, the Arab population increased by 270% while only increasing by 100% in other regions.

Rebuttal: What aerial photos? (no aerial photos of Jerusalem from 1930s exist).
