These people have no citizenship, no rights, no security, and nowhere to turn. Many of them have been Israeli prisoners, and all of them have relatives currently in Israeli prisons where torture is commonplace. They may labor for Israeli employers but may not enjoy the benefits of Israeli citizen workers. They may work within the 1948 borders but must sleep within their own Israeli-imposed ghettos. Race and religion is one aspect of this nightmare.
Land is another.
Since 1967, more than half of the best Palestinian land in the Occupied Territories has been expropriated for the benefit of a shrinking Israeli-Jewish population. Daily these expropriations continue without any judicial recourse whatsoever, while a burgeoning Palestin-ian population must survive with less land and fewer resources. Demographics is another element. More Jews leave Israel than are replaced by immigration or births. At the same time, despite the daily expulsions and high infant mortality, Palestinians in the Occupied Territories have the highest birthrate in the world.
