there can be only one type of covert strike from India, that is to help Pakistan in case of any type of state level challenge they may face, and on invitation only..........
Pakistan is facing a serious threat from terrorists/militants including US's/British rulers who have bought half of the pakistani politicians with many military bosses itself. even if Baluchistan may get separated, like how US is giving protection to BLA's training camps in Afghan, then it will bring a serious challenge to India/Iran altogether as it will then become a military base of NATO in that so much strategically important area. until Pakistani rulers can't prove themselves loyal to pakistan's civilians itself, India must not try to fight with that pakistan which is on the finger of western rulers right now. even if India may face 2-3 Mumbai Attacks type things, India would only try to fix the problems and help pakistan's 'honest' people find those who were played on the hands of CIA to do that, similar to 26/11 2008 Mumbai attack......
militants of pakistan are the bigger threat to pakistan than india and if they scored 1000 on indian side during last 10 years then over 30,000 they scored in pakistan itself? India can only defend itself from this mess made in pakistan side and hope, pakistan may fix it soon. but I would also recommend that if proper evidence of CIA's involvements are found in any more terror attack on India then IAF must take a strike on the military bases of US in this region to level the number.
i mean, until pakistan is in full control of US/UK, India would answer only to US/UK, in case of any attack originated from pakistan......
