The suggestion was dismissed by most of Israel’s interlocutors — who include the United States and Britain — because of the risk that such a mass displacement could become permanent. These countries fear that such a development might destabilize Egypt and lock significant numbers of Palestinians out of their homeland, according to the diplomats, who spoke anonymously in order to discuss a sensitive matter more freely.
Curious, then, that one of the biggest stumbling blocks to any peace deal has been the so-called 'right of return' of Palestinian 'refugees'.
First- to explain the quote marks. For centuries, 'Palestinian' meant anyone living in Palestine: the current usage denoting a distinct and separate nation is essentially a fiction. The vast majority of them were itinerant, migratory labourers, following seasonal work around the region. Many of them- as has been noted here before- were not originally from Palestine, and a fair number of them were not even Arabs. Some of them arrived as recently as 1946.
Fast-forward to the present day. There are now millions of self-identifying Palestinians in the Middle East. Most of them were not born in either the West Bank or Gaza, and most have never visited Palestine.
The 'right of return' to homes they may well have only occupied fleetingly, and on a temporary basis, which a good number left of their own volition (there is massive argument among historians to this day about how many were forced off and how many left of their own free will), and to which most Palestinians today have very little connection is not the absolute, written-in-stone moral imperative that many seem to believe it to be.
Now, if they were somehow allowed to enter Israel, that would massively destabilise that country. To allow some 5 million immigrants into a nation of 9 million, and moreover, immigrants that do not share any of the cultural or religious values of Israel, and who in all likelihood hate Israel and hate the Jews, would destroy Israel as we know it.
I suspect this is the real reason for the dogged insistence on the 'right if return': it's more about how this would destroy Israel from the inside out, rather than a genuine desire to see families return to claimed ancestral roots that are highly tenuous. This is merely my opinion, though.
Please note that I am not in any way denying that Arabs were forced off their land. The creation of Israel was a calamity for many Palestinian Arabs. However, demanding an action that realistically could not be achieved, is not helpful.
For some to oppose temporarily settling Palestinians in Egypt, on the grounds that it would destabilise that country, whilst simultaneously insisting on the permanent destabilisation of Israel though an almost identical action, appears to me to be hypocritical and misguided.
