Perhaps because the US & Pakistan alliance had already subdued many of the dangerous Taliban terrorists groups. Therefore maybe the US doesn't see the need to continue pouring money into fighting the Taliban or other terrorist groups in Pakistan anymore?Too little....too late....
Pakistan wont bother with this, as effectively Pakistan is already out of that scenario that these actions will bother. In fact US cant afford to lose Pakistan support in particular the supply line.
I believe majority of this forum members are well versed & aware about the reality, hence just ignore these news as this is nothing but dirty politics.
