Perhaps not to the extent believed generally. Complacency, maybe a blind eye here and there. Those are things that might be possible. However, Pakistan has not provided shelter, logistics, weapons and training to these freedom fighters. And on top of it all, please consider the duplicity of the US when it wants Pakistan to fights the Talibaan and yet does not recognize the Talibaan as terrorists.
On the other hand, the US sells all kinds of weapons to our arch enemy, weapons that will only be used against Pakistan. I seriously do not understand how treasonous some of my military and political leadership is that they did not safeguard the interests of Pakistan and allowed the US to sell high tech weapons to India without repercussions.
