You belie the typical mindset of the Indian 10%er, behind which the saffron trishul wielding 90% gather their forces.
Pakistanis never seek violent solutions. We seek to explain, to reason, to cite historical facts and justifications, for our assertions. We accommodate and tolerate, ultimately creating a platform for compromise, which leads us all to peace and prosperity. That is why we offer diplomacy first and foremost. That is why Pakistan itself was born of intelligent and skilful negotiation in the first place - our founder was a skilled statesman who argued his case eloquently on the basis of evidence and reason, not a brahmin ascetic who commanded hordes of lower castes to lie down and create physical barriers until his opponents yielded from simple frustration.
I digress, but the point being made is that Pakistan is never "happy" or "sad" over events that result inevitably in violent outcomes.
The security situation in occupied Kashmir is one of Delhi's own making, entirely. Pakistan warned of this egregious outcome. Delhi ignored the path of diplomacy that was desired by Pakistan and a platform for which was offered by countless neutral countries and organisations, to serve both our nations and the interests of Kashmiris.
The path of violence has been chosen by Delhi because the people it serves believe in Bollywood outcomes and the reductionist framing of serious diplomatic issues as constant "struggles" between "good" and "evil". Such immaturity cannot sustain itself forever.
