Army is not just worried about controlling ISI, which of course is its very important strategic arm to both control domestic and foreign policy issues, the army wants to overtly or covertly control everything. In their eyes, the civilian set up are inefficient, weak and corrupt and can’t be trusted with determining or taking care of the strategic objectives of Pakistan. But essentially coming back to your question, ISI functions the same way lot of other international spy organizations do, except for the fact that the role becomes more prominent and is showcased differently because it is a direct reflection on Pakistan’s civil military relations. The debate should not be confined to the role of ISI, ISI is just a tool. It is the role of the so called Pakistan’s establishment that must be questioned.
