This isn't about human rights, this is about people living with the constant fear of islamic monsters who have vowed to exterminate them. You can only take the rats in your house nibbling at your baby's toes for so long before you break out the rat poison.
Well except for running an ethno-state. that is.
Sure there are Arab citizens of Israel. They are not trying to remove them ("cleanse them") right now. But effectively the creation of Israel did result in lots of people being "cleansed" out of the area where Israel sits today. And, to be fair at the same time even more Jews were "cleansed" out of surrounding countries.
So, I'm not sure tha Jews are that concerned with ethnic cleansing. And I think that's probably a realistic thing for them.
Yugoslavia was beset with ethnic civil war throughout the 1990s, until mutual "ethnic-cleansings" were completed. Now it's a much more peaceful place. It's like sending the boys to their own rooms after a fight. Each group has it's own room in Yugoslavia now. The idea that the old Yugoslavia should have been held together with multicultural integration of everyone everywhere is a stupid idea.
I believe if a two state solution is arrived at Arab Israeli's will be encouraged to move there. The Jews are quite aware that they have a future problem with the Arab minority and their birthrates.
