Arabs moved into the area for 1300 years, you accept it or not. That is how they constituted the majority of the population by WWI.
Again, show me serious, peer-reviewed historical evidence of a mass migratory movement from the arabian peninsula to Palestine similar to the mass immigration wave of Bantu peoples from Central to Southern Africa.
If you are unable to present me this historic evidence, I'm sorry, but I and the rest of the world will continue to support the historic facts presented by the entire scientific community:
The native population was arabized due to the arab conquest just like the native inhabitants of France, Spain and Portugal were latinized by the Roman conquest.
"After 4, 3, 2 or even 1 century without claiming your right to the place of origin of your ancestors it ceases to be your homeland."
There is no saying, or international law which says that.
There is no piece of paper signed by foreign diplomats in the world with no power over any foreign nation that will force Britain, Germany or any other country to accept even 1 million american immigrants on the grounds that they are descendants from british or german colonists and rightfully so...
When your family moves to the other side of the world and remains there for more than a century without claiming their right to live in their ancient homeland even once it ceases to be your homeland.
A given country might even accept them after 100, 150 years but it is the prerrogative of the country in question not a natural right of the individual.
All other indigenous people in all all conquered Arab or European invasions continue to be the indigenous inhabitants of those lands.
The Kurds of Kurdistan are the only other indigenous people invaded by the Arabs who have recently taken control of part of their ancient homeland, even if they are still not recognized as a State due to Turkish intervention.
Apaches and Kurds remained in their historical homelands...
They didn't spend 2 millenia in China and then on a beautiful day decided to "return" to America - Kurdistan.
And european Jews are racially europeans who can't even claim any native jewish ancestry.
No indigenous people anywhere in the world have ever given up claim to their homelands, no matter how much time has passed.
And they never will.
The pseudo semitic "Jews" of Europe clearly did.
For 2 millenia they couldn't even bothered to go live in Palestine despite being allowed to by several rulers of the region.
Hell... most of them preferred to live in neighboring Damascus, Aleppo and Bhaghdad than in their so-called "homeland".
So much for "unbreakable ties to the homeland".
