CIA had tapped the phones of the German chancellor in the past using their base in UK. There are no permanent friends or enemies for US. Only permanent corporate interests. They kill traitors inside their country and use traitors of other countries for their benefits. It makes them the most powerful nation in the world. What is Pakistan for them? Nothing more than a dump of smelly garbage. When the head of the Army and head of Intelligence is in their pocket and the legislators are willing to sell their mothers for a few dollars US does not feel it more than an itch of a mosquito bite even if the whole country is on the roads.
