A mature response to the recent incidents would be for both countries to acknowledge that such petty killings accomplish absolutely nothing. What did this attack accomplish, 40 odd families destroyed forever, tens of thousands of people affected and the the gears of revenge being given a nice good oiling.
No party is innocent here. India funds terrorism in Pakistan, Pakistan does it in India. Petty shadow dealings that will never ever have any meaningful impact as far as achieving any of your goals is concerned, just sad point scoring.
The likes of Gambhir are actually disgusting human beings. Its so easy for the likes of him to play the brave hero from the comfort of his position, he'll never be on the frontlines thats for sure, but its easy to act all bravado and encourage tens of thousands more Indian soldiers be sent to their deaths, as well as rival forces, to satisfy an ego. He's either a brainwashing victim of a military complex or an odious human being, perhaps both. Its a sad indictment of our world that wealthy celebrities in the comfort of their mansions typing guff on a keyboard constitutes anything but public embarrassment, let alone being seen as "patriotic" "strong" "brave" etc etc.
The most depressing aspect of it is that the higher ups in the game here are probably quite satisfied with this. From a Pakistani POV in some perverted way they will have been seen to damage a foe, and from an Indian POV they can probably expect a nice funding boost to beef up coffers.
Every single person who has ever given or lost their lives in this conflict will have done so in vain, thats the most devastating thing. Because rather than pause and reflect on the consequences of these actions and this conflict on both sides, and focusing instead on a narrow perspective and viewpoint, the cycle continues, they kill us we kill them so they kill us and so we kill them etc etc etc. No attempts at compromise, finding some, any common ground or purpose to bring some modicum of peace, nope, hyperbolic right wing rhetoric, nationalistic drum beating and hyperemotional responses remain par for the course. A very sad state of affairs, one not unique to these two nations.
Go forward 100 years this will keep going. And like all conflicts you can be absolutely certain that many many people are making a serious sum of money off it.
