This whole security situation of Taliban and religious fanaticism was started and developed by ISI people like Hamid Gul and Mirza Aslam Baig.
So yes, ISI under these people was more loyal to "Amirul Momineen" of Afghanistan than the Mumlikat e Khudadad Pakistan.
If you think supporting Taliban and training people to cause violence against others was a good thing to do then there is no point arguing with you. In that case, you can support "Amirul Momineen" Nawaz Sharif as much as you want, but then you are not my audience. I am talking to people from Punjab who are against religious violence and consider people like Taliban the bigots.
