Is not the sophistication of attack on GHQ an indication that the attacker had some level of support from fundamentalist elements within Pakistani forces?
No . Not at all. Perhaps this group is directlly or indirectly playing in hand of India or India & Israeel together. All their last activeties were with aim to down Pakistan and this man Aqeel @ Dr Usman was previously medical cour man so he was aware of GHQ surrounding. Their previos activeties like attack on Sri-Lankan team narrates their desires.
