Still, to a great extent, the biggest contributing factor to the current extremely low Jewish populations in the Middle East outside Israel has been migration or flight to Israel. For example, in Iran, even before the Islamic Revolution and the wave of antisemitic persecution that followed it, which could be described at least as ethnic cleansing if not outright genocide, there had been significant migration of Iranian Jews to Israel.
But when you directly tell the vast majority of the population of a region (>80%) to flee their homes and migrate south on foot or be killed in bombings, and then still kill more than 20 000 women and children, there is no equivocation. This is genocide.
