You are basing it on a recent song that is composed after the Balestinian Beoble were invented. Prior to the early 1800’s there was no mention of Balestinians: in 1920(League of Nations) there were no Balestinians: in UNGA181 there were no Balestinians: in UNSC242 there were no Balestinians.
Recently in the Peace treaties between Israel and Egypt and Israel and Jordan there were no Balestinians as well as in the UNWRA resolution of 1949.
Stupidity is not an excuse to LIE.
