The Eidah Chareidus is not Chasidish. Rav Shterbuch shlita isn’t Chasidish. Rav Yosef Chaim Sonnenfeld ZT’L, its founder, isn’t Chasidish. They were anti-Zionist under their Litvish leadership.
Both the first and the second Satmar Rebbe’s were the leaders of the Eidah Chareidus. In fact, they are the only two leaders who didn’t live in Eretz Yisroel.
