They didn't ALL leave. All of the Jew's were all scattered around the country without anyone else knowing. It says that the jews didn't actually leave, they were all scattered around the country n' in Jeruserlem (Fail spelling lol) practically like hiding themselves.
Even when they left, they still faught against eachother. And guess what? I still believe that the Jews won that war. Plus, just because the palestine's took over the land, doesn't mean they OWN the land and doesn't even mean that they made that country in the first place.
But they faught just for the land, and i believe that the jews won that war. So what the jews left, they still have ownership of that land. Plus, they won the war, they should at least get the land that belonged to them in the first place.
Many people from Israel say that the Palestine have NEVER been mentioned in the Koran//Quran. Sure some say they it does say Palestine in some peoples books but do they have evidence? On most sites, all of them say that Palestine has never been mentioned 40 times or more because it has NEVER been mentioned.
