That is patently false. Caroline Glick just had an article about them allowing 100 thousand Arabs from the PA who are married to Arabs in Israel to move there. Separation is a myth.
What has that got to do with the price of tea in China?
If you want to get rid of all Arabs within Israel, then propose a "Final Solution" for Arabs within Israel and see how far that gets you.
In the Real World, Israel will be separating themselves from Arabs who want to kill them and not from Arabs who have been living peacefully in Israel since 1948.
If Israel considers a certain Arab-Israeli citizen a security risk, Israel can deport his treasonous butt to the opposite side of the Israeli Wall.
If your contention is that loyal and peaceful Arabs may not live within Israel, then that is as wrong as saying that loyal and peaceful Jews did not deserve to live within Germany in the 1930's.
