akuperma: You’re wrong when you say many if not most hareidim follow the views of the Satmar Rebbe. Unless, of course, you’re just referring to Satmar chassidim when you say “many”, as there are many of them.
The leading Rabbonim in Israel do not agree with it. After all, they tell people to run for office, vote, and participate in the running of the state. Most Rabbonim in the US share the same views as the Rabbonim in Israel. The only ones who are adamantly opposed to Israel are Satmar. I’d say Neturei Karta as well, but with the Satmar chassidim going down to protest Netanyahu recently, holding up signs for the world to see one Jew protesting against another, I now lump them together.
