Actually, its the other Arab countries that want to keep the Palestinians in a camp,
Did you know, that after the '48' war, the Egyptions expelled all its Jews, there were approximately the same amount of refugees, jews from Egypt, Arabs from Palestine.
Egypt promised that all the housing that had belonged to the Jews, would go to the Refugees from Palestine, but it never happened.
I was under the impression it was the palestinians that wanted to eliminate Israel from the map,The jews said when Israel was formed they would rather all die than forsake that land and they are sticking by what they said.
For the others,
After the Romans left, defeated by the invading Arab armies, until the creation of Israel, there has never been a goverment of what the Romans called Palestine, (Their word for Philistine), and never actuall a country called Palestine.
