...who lost it in war to the Hebrews...who lost it in war to the Romans....who left....then the locals lost it in war to the Arab invaders....then the Arabs lost it in war to the Israelis.....
...um what's your actual point?
War makes borders. Deal with it and move on.
You know they don't listen to reason. They make up ad hoc arguments and appeal to principles that have no communion with reality, and which they don't really believe in themselves.
Will the Arabs give Egypt back to -- I don't know, the native Egyptians ?
Should every person with Spanish blood move out of South America back to Spain ?
Every Brazilian with Portuguese blood go back to Portugal ?
Every Egyptian with Arab blood go back to the Hijaz peninsula ?
Every Afro-American or Afro-Caribbean go back to Africa ?
Every Turk go back to the plains, and give Greece back to the Greeks ?
And indeed, the unexplainably pro-Palestinian, anti-Israeli Scandi-navalim should give all their land back to the Sami, and go back to Denmark and Germany from whence they came.
The Japanese would have to give back the land to the Ainu. The white Americans and Oceanians would generally have to go back to Britain. The British would have to go back to France or Germany I guess. Hence the white Americans / Oceanians would have to emigrate en masse to France or Germany.
Sounds plausible, right ? This is definetely gonna happen. Real soon.
