There were more Jewish refugees than Arab refugees. And they were real people whose lives were totally disrupted.
I know a Jewish woman here in NC whose father operated the only steel mill in the mid-east, in Alexandria. They lived in a mansion on the sea.
After the 1948 war, the Egyptians periodically arrested the father for spying for Israel. They knew he wasn't a spy. They just wanted the bribes necessary to get him out of jail.
They fled Egypt during the 1956 war, losing everything. The father, after several years of wandering, managed to get a job in the U.S. working for a steel company.
