My take on it is much different from most due to listening to people who really studied history. The number may be real, but not caused the way they claim. Supply lines getting cut, forced (not by Nazis) migration to Palestine and disease that is common in war all contributed. My brother made his college history presentation about this subject and was berated by the professor in front of the class but privately was told by the same professor that he was correct. The Zionist staged the entire thing to gain a homeland and they are not close to their ultimate goal
