Sorry to say are you are day dreaming man? IN is big and potent force in region but its not invincible and don't talk about Russian system as PN don't use them all major electronics comes from west and all strikes will be done in net centric environment so PN, PAF & PA know well whom they have to deal and how they have deal with it. Further PN is trained by USN in terms of net centric warfare so u can think what kind of capacity they have provided us and what we have learned with the most advance net centric fighting NAVY. They were also training PN how to handle big enemy by utilizing their resources in a net centric environment.
on the second part of your post, I have never said that they have not given us system, yes they have but it was old days story, what they do now they teach our Engineers, scientists, technicians etc. so they don't have provide any thing, we built it by our own with making them better by using knowledge learned and systems purchased from west (F-22P is good example of that) means they become new systems with better quality.
