Is Zionism a secular form of judaism or a religious form or both?

Although Zionism is a Jewish phenomenon, it does not claim to be a form of Judaism. Rather, it is an emotional, political and practical entity within much of the Jewish people, but by no means all of them. There are both religious and secular Zionists in large numbers.

Many Orthodox Jews feel that Zionism has attempted to replace the religious core of Judaism with secular values plus watered-down Judaism.
