Netanyahu and Lieberman and their buddies, secular as they are, are not simply beholden to the Rabbis because they must be because there is no religion/state separation, Netanyahu et al.

In other words, for Netanyahu and Lieberman and their ilk, religion is just a handmaiden for their long term ethnic cleansing project.
