Fault lies with the Pakistan Govt. they have a double speak, by heart they do not want to harm taliban otherwise these thugs could also be beheaded in a similar cruel manner. Will someone tell who is providing arms and ammunition to them? Who is providing logistic facilities? We are our own enemies. The ideology of jahiliyat will sink the whole Pakistan. This could have been possible in trible Arab world of centuries ago. This is modern age, I don't know how it is being tolerated in present times,
Even if the Pakistani gov't was giving secret support to these goons, or even shelter from the bombs going off in Afghanistan in 2001, doesn't necessarily mean that is still the case.
Currently, Taliban is funded by the help from their opium farmer slaves who sell opium raw materials to them for dirt cheap which are sold on the market allowing them to rake in millions. On top of that, they've joined forces with thievery mafias around Pakistan and outside - so when your cell phone gets robbed, don't be suprised if some idiot near Tora Bora picks up to say hello.
