One of the legal principles of Israel is:
> The right to exercise national self-determination in the State of Israel is unique to the Jewish people. [0]
There's also a legal path from citizenship to legal-residency, which I would surmise is used almost exclusively on non-Jewish citizens, as well as the blanket permission for all Jewish people (and no one else) to become citizens of Israel.

While we are on the subject, did you know that it's illegal for an Arab in the self-governed parts of West Bank to sell land to a Jew? And that the official penalty for doing so is death?
Also, take a look at the awful governments in West Bank and Gaza and how they abuse their citizens. You don't see hordes of opressed Israeli Arabs fleeing to the Gaza Strip do you?
