But you already knew that. The more interesting point is that if the Arabs (in this case the Palestinians), have given up a claim to pre 1967 Israel, just why do they need a refugee camp already within the borders of the state they seek? That seems inconsistent.
The inconsistency can be squared three ways: 1) The PA simply hasn't had the time to clean out the refugee can't since they gave up a claim to pre 1967 Israel, but it was occuring in due course, 2) the PA is corrupt and the money is all going to Switzerland, and/or perhaps not so corrupt, but it has other priorities, to wit using the money to buy or manufacture arms, or 3) the PA has not abandoned its claim to Israel within its pre 1967 Israel. I guess you can mix and match 2) and 3). They are not mutually exclusive.
Just my thoughts per your inquiry.
Here you have a clue.
What is this other society? The Arabs in the territories call themselves "Palestinians" as do more and more of those in Israel and in the "refugee camps" located in countries surrounding Israel. Same with a majority of Jordanians. Arafat, the Egyptian, is also a "Palestinian". And by the way, they concede in their Charter that I too am a "Palestinian".
So what is this society-where the criteria for membership is manipulated at will-other then front line shock troops in the never ending Arab national war against the Jews? And more important why does this make believe society, indistinguishable from other Arabs, merit their own (another Arab) State?
