We should focus on Pakistan & Pakistan's interest. Supporting jihadi terrorists is not in interested of Pakistan & Taliban monster was created by PA & event today it sustained by PA & ISI. That is pretty well known fact.
Now, the question is, how do we take control of border areas & prevent terrorists from turning those areas into launching pad for terrorism across the globe. We also need to understand that if there is major terrorist attack in the US...gues who Americans are going to bomb back to stoneage?
Pakistan had long ago recommended sealing of Pak-Afghan border but Afghanistan and coalition didn't like the idea. Afghanistan may have opposed it because of Durand-line issue. But it is important for both Pakistan and Afghanistan to seal the border entirely. Once the border is sealed militants supply lines on both sides will be cut. Then Pakistan can focus on targetting militants on its side and Afgh/coalition can focus on militants on their side.
