Seriously! The Arabs (as they identified then before identifying as Palestinians in the 1960’s to aid their cause to annihilate Israel) in the geographic region of Palestine in 1948 and before, did not have a sovereign State, it was not their territory, they were part of the Ottoman Empire, then under a British mandate who captured the territory from the Ottoman Empire.
Many Arab workers emigrated into the region in the early 19th century, to work in the budding economy
(created by the Jews). Below are a few common surnames among Palestinians in Gaza and the West Bank.
Sidwai family - "from Sidon" (Lebanon)
Inshasi family - "from Inshas" (Egypt)
Halabi family - "from Halab" (Halab is Aleppo in arabic)
Harami family - "from Haram" (Syria)
Zarqawi family - "from Zarqa" (Jordan)
Al-Sorani family - "from Soran" (Iraq)
Al-Karaki family - "from Karek" (Jordan)
Hejazi family - "from Hejaz" (Saudia Ariba)
Al Kiswani family - "from kiswah" (Syria)
Al-masri family - "The Egyptians" (Egypt)
Yasser Arafat was an Egyptian!
So whose land was taken away?
It was divided so both peoples could have their own land, economy and autonomy. The Jews were allocated a large area of desert.
Instead of rejoicing and declaring their own independence in the region (after the area being part of the Ottoman Empire for centuries), like Israel did, the Arabs decided to declare war, then a few more wars, then decades of terrorism then war again.
They weren’t bothered about creating their own State while the area was illegally occupied by Egypt for almost twenty years.
I gently advise you do some research, which isn’t TikTok, if you want to give a serious opinion.
