Why are Russians supposed to integrate? They are not Jews (if you mean Russian spouses of Jews). They are there so that their Jewish spouses are there, too. They don't "multiply" in the sense that their Israeli-born kids do not grow up Russians, so it's not like Israel is risking being "liberated" by some Putin successor someday, their culture dies with themselves.

I mean Russians Jews are not integrating. Just because you are a Jew does not mean that you share the values and culture of other Jews. Just like ethnic Russians culture as been molded by Stalinism and communism, so has Russian Jewish culture. By large they have the same backward values and are bringing them to Israel (this already shows in politics and other things).
