Yes, tens of thousands of Jews capriciously packed their bags and left the country. Thanks to Mitchell Bard's excellent Myths and Facts, here's a synopsis of what actually happened to Egypt's Jews:Egypt was once home to tens of thousands of Jews, but most left decades ago and only a few dozen live in the Arab state.
Between June and November 1948, bombs set off in the Jewish Quarter of Cairo killed more than 70 Jews and wounded nearly 200.
In 1956, the Egyptian government used the Sinai Campaign as a pretext for expelling almost 25,000 Egyptian Jews and confiscating their property. Approximately 1,000 more Jews were sent to prisons and detention camps.
On November 23, 1956, a proclamation signed by the Minister of Religious Affairs, and read aloud in mosques throughout Egypt, declared that "all Jews are Zionists and enemies of the state," and promised that they would soon be expelled . Thousands of Jews were ordered to leave the country. They were allowed to take only one suitcase and a small sum of cash, and forced to sign declarations "donating" their property to the Egyptian government. Foreign observers reported that members of Jewish families were taken hostage, apparently to insure that those forced to leave did not speak out against the Egyptian government.
And so on.
