I have my own family members, who are not Jews, residing in Israel and have full citizenship rights and benefits. They are more satisfied by their treatment by the State then some of my Jewish family members. I know many non Jews, who live in Israel. If you mean Israeli Arabs, so why they refuse to be part of the future Palestinian State with their current houses being on other side of the border? If Israel is so bad to them, why on Earth they would like to stay in Israel and keep their Israeli passports?
