The other day I was watching CNN. I found that most of the US policy makers know that all terrorists are either hiding in Pakistan or its neighbouring areas.They also know that some top offcials are making sure that they be safe. US has invested billions of dollrs to elliminate the terrorists and its network but they didn't get good responce from Pak government.They just took money on the name of terror.I wanted to know ahy US trusted Pak and if they know about the facts then why didn't they react the same way they did on Iraq and Afganistan.May be US fears Pakistans nuclear capabilities???
