No your wrong, "Pal.est.ine.", or "Pal.est.in.ians" does exist, you can find it on maps. Look under your feet you may see it.
When the Roman Emperor Hadrian conquered the land of Israel and sent the Jewish people to the four corners of the Earth, he renamed the territory
Palestina after the Philistines, historical enemies of the Jewish people. This was done by Hadrian to spite the Jewish people.

Palestina', just wasteland.
