I met Caroline Glick, I even interviewed her when I was working for Arutz Sheva. I can tell you that she is very smart, and deep down she knows the Arabs will always be an existential threat. Off the record she will admit as much. But, Caroline is part of the Israeli establishment, even if just barely, and she will not risk that by coming out and saying we must expel the Arabs and establish a Medinat Torah. The closest she will come is arguing that Israel shouldnt commit suicide by surrendering the high ground. Sadly for the a member of the branja thats radical.
