Just say it, Israel is installing controlled opposition in Egypt through influence.There is a historic Jewish quarter in Cairo which still has a number of Jews living in it, dating back to atleast the 12th century, composed of groups that fled the Spanish Inquisition in Iberia. His mother was from there apparently.
Foreign Jews, including Israelis, are now allowed to roam in Egypt freely, thanks to Sisi, while there is an active effort to bury old interviews of his origins.
