Here is some establishment boys analysis in short : Anti Imran Khan foreign campaign started right after Indian plane shutdown. When PTI shutoff airspace and sea route, which showed the extreme weakness of India in the region, West wants India to stand against China, an ultimate goal to neutralized China with the help of Pakistan. Also during that standoff , it badly hurt GCC trade with India. So, its Khan vs West, GCC - India. Then Nawaz factor came in, to bring him in power, to protect India hegemony in the region. Nawaz known for better server of GCC-India, Western Interest. So, basically no one serving Pak interest, our whole system is slave of foreign interest
