To give an even clearer perspective on just how insane/fanatical the Taliban are, they are completely prepared to sacrifice their entire country and population, and are amassing an "attack force" to exact revenge on any bordering countries who offer the U.S./Nato access to their air space, or their land as a staging ground for ground troups -- ALL to protect their "guest" and his henchmen.

(I don't think they're going to have sort of "attack force" left to exact their revenge.)
