A better question would be...........are Jews entitled to have their own state or not? If not, why not?
Nobody is entotled to have their own state at the expense of the people who were already there.
If you want to move somewhere you have to share it with the people who were there first. Of course as soon as a single generation is passed, the new genetation has as much right to a voice in government no matter who their parents were.
In this way your question is malformed. "Do people have a right to move around and have some say in how things are run wherever they end up?"
Most certainly I would say yes to that better question. But that means the palestinians need to get that same deal, the right to have some equal say in how things are run in the place they already were, in addition to the voice the others who moved in should have...
Currently, neither side wants to acknowledge the voice of the other as valid. Anyone whould have a right to move in. Anyone who lives there should have a voice in government. The government shouls NOT favor the voices of any one group except to defend the fundamental rights of all as equals
