^ that past is not that far past Kaptaan saab. Previous behaviour of Pakistani involvment was always had the same reaction in Pakistan. No we did not do it. Ofcourse you would not have done it but there are enough places in Pakistan where things are not exactly in Govt. hands (including military's) .
Dude, do you see the difference in the past ones and this one? In the past ISI was blamed so it was very unlikely any "public" action would've been taken to satisfy India unless you want Pakistani government to publish internal affairs of ISI, internal emails, who was punished and who was not, which would be idiotic in my opinion.
This particular one is being blamed on "private" parties by Indian government itself and still not providing details/solid-proof, so what do you think Pakistan can do?
