Answer:
My opinion is that it is fair that the Jewish People have a place to claim as their own, that is also their ancestral land, since they have been an errand people since the times of the Roman Empire, who have been expelled from many countries, and who have been subject to discrimination and poor treament.
However, it would also be fair that the Palestian Arabs have a share of the land too, because they were dwelling those land for more than a millenium before the Jewish began to settle back. This is why the most reasonable policy for the area would be a two state solution: one state for the Jewish People, and one state for the Palestinian Arabs.
