Most TTP are not comprised of local tribes, or at least not of
one tribe, consists mostly of newbee punjabi TTP members who think they are entitled to that culture. These people have killed countless local tribals in the name of their Wahabi lord. This is in all probability payback from the local tribes.
The problem here on this forum is whenever they hear the word "TTP", they think it's synonymous with Pashtuns, that's hardly the case. TTP as a body is composed of more foreign (Punjabi Taliban LeJ LeT(new player) foreign fighters) than it is composed of Pashtuns from any local tribe. It has just been sold as TTP = Pasthuns. That's where the problem lies. The media.
I personally intend to see to it that I catch few of these foreign ones, and extract some relevant info. Wish me luck on my trip.
