There are groups using the NK name illegitimately. The real NK in Yerushalayim have nothing to do with them. The Satmar Rebbe and Brisker Rov were very close to NK founder Rav Amram Blau.
Also, Pappenheim doesn’t represent the Eida, despite his media campaign claiming so.
All that doesn’t address the point that the Satmar Rov did not agree with supporting the Palestinians.
