In the case of the Palestinian arabs, things are altogether different. Those who fled in the Nakba, or were driven out, took the title deeds of their property with them, and some even their house keys. That was almost exactly sixty years ago (Israel celebrates this fact this year) and so well within living memory of the displaced Palestinians.
CarolC then wrote: The people whom the government of Israel is expelling are the descendants of the original people to live in that area. They have the older claim. Jews ruled the area for a few hundred years, and then some of them left.
So can we put these together and posit the question: "If they are the descendants of the original people, then from whom did they procure these 'title deeds'"?
The answer is that the prior claims arguments of both the above are without merit. Title deeds of even Turkish origin are like the permission of one house breaker to another. If one wants to selectively pick an original inhabitant, one of course may, and I'm allowed to selectively pick the one who wrote down thousands of years ago "If I forget thee Oh Jerusalem, may my right hand wither..."
And again I make the point that the failure to acknowledge Jews as Palestinians by right has led to much of this blundering about in violence on the part of the Arabs and their co-opts.
