Regarding what exactly? You repeated what I said about Jews persecution in Europe but jus added details (thanks for the info i guess?).Man, ignorance is not a virtue.
That is not entirely correct, but lets assume it is, then the cause is clear, the Arabs considers that Land to be Arab, whether Jews, Christians or Muslims. Ben Gurion was Polish. That overreaction would have been because of this and not the fact they are Jewish.All large Jewish communities were expelled from most Arab countries and their properties were confiscated in pretext that they have sympathy toward Israel
Now, the Reality (ignorance is not a virtue indeed). The massive Immigration of the Arab Jews was sponsored, encouraged, and facilitated by many Zionist institutions.
However, all of this, that History, or how or why Israel came to be does not excuse any of what is happening today. This constant going back is simply to try to gather sympathy and remind people that Jewish have suffered indeed, and that they were Victims. True as it may be, it does not mean that they can wipe out others, especially the ones that have nothing to do with their sufferings.
