"They and their children have never been allowed to return despite having long established roots,property etc in the city."
And the 820,000 Jews driven out of Arab countries- they are not entitled to be resettled in the land that the 640,000 Arabs who fled abandoned? Try blaming the ARAB nations that did not allow the refugees to settle as citizens.
Or do you insist that Jews are not human beings, who are entitled to the same justice as Arabs?
