I would love to get back to you on this soon as I've gathered info from many videos about Neturei Karta but unfortunately I'm a little busy right now. ان شاء اللہ my research will probably take around two posts.
brother don't call those accursed murtaddeen as "Ahmadiyya" and yes indeed they are devils who are actually in bed with the zionist project. i have no idea how close this neturei karta is to the qadianis, lot of ordinary kafir politicians too mingle with them, in india for example even navjot singh sidhu but whatever it is, if at all these guys are well-connected to qadianis, i'd be wary of them.
I would love to talk about this further as I've been researching this topic as well but please look at this for now. Another thing is that the Ahmadiyya's Middle East HQ just so happens to be in Haifa... so Isr*el definitely has some not insignificant relationship with Ahmadiyya.
I bumped into this organization/group in the last couple of months. Wondering if other people have more knowledge on them or if they feel we can leverage them, and if so, how well. https://en.m.wikipedia.org/wiki/Neturei_Karta https://www.adl.org/resources/backgrounder/neturei-karta
