Palestine was not an independent nation when it was given to Israel. It has been a colonial holding of various empires since it was conquered.
Thus, there is no "returned". Unless you're nostalgic for the British mandate, which was certainly not about to grant it independence.
You conveniently behave as though the people who were living there the whole time didn't exist then and don't exist now and would be perfectly fine with living in a country that would treat them as second-class citizens because they don't fit into the prevailing conception of national identity.
