It is either a serious breach of discipline, or it is implementation of a considered policy by the Pakistan army High Command. In either case, it reflects poorly on the Pakistan Army that, until Partition in 1947, was part of the Indian Army that has exalted personal ‘honour’ above all other virtues. It seems to be a deliberate policy because there’s a discernible pattern to the beheadings, the gouging out of eyes, the cutting off of genitals dating from the Kargil skirmish, which evidenced the extreme brutality visited upon Captain Kalia, by the Northern Light Infantry intruders, revealing a regression to primitive warfare. In the latest incident in the Sona Gali area of Poonch, variously the 22 Baloch, the 29 Baloch, and the Special Service Group commando, have been held responsible for the barbarity. (There is even talk of the terrorist LeT being part of the raiding party working under Pakistan Army aegis that actually committed the atrocity, though this story seems to be a belated Pakistani attempt to distance the army from this heinous act.) That several different regiments are talked of as having engaged in such inhumane practices suggests that a policy of mutilation was carried out by Pakistan Army soldiers under orders. May be, the Pakistan Army action was in retaliation for one of its jawans killed in the Uri sector two days previous. But that does not justify the post-death horrors inflicted on the bodies of the slain Indian troopeers.
Islamabad certainly jumped on the opportunity to get the UN involved in a Kasmir-related issue, setting a trap by getting India to agree to the UN Military Obesrver Group for India and Pakistan (UNMOGIP) investigating and judging the veracity of what Pakistan claims are mere allegations of mutilation. Fortunately, GOI did not fall for this ruse. India has paid a heavy price for involving the UN in 1948 when it could easily have taken back all of J&K, including the Northern Areas (Gilgit and Baltistan) under Pakistni occupation, but Nehru sought UN intervention instead in the expectation of a fair verdict requiring Pakistan to vacate all the areas previously part of the erstwhile princely state of J&K that had acceded to the Indian Union. That didn’t happen, and India has been discommoded ever since.
That leaves the Indian Army to mete out condign punishment in any manner it chooses below the bilateral relations-diplomatic radar. This the Indian Army, hopefully, will do. After all, what is the Special Forces commando, penny-packeted as force reserve with the GOC-in-C, Northern Command meant for other than to mount, among other things, severe punitive missions on such occasions? Meanwhile, Indian TV comperes frothing at the mouth should wipe the foam of their lips, calm down, and the GOI get back to the normalization talks. This is an issue between the armies — a bit of intra-mural blood sport the two forces have been indulging in since the Line of Control came into being in J&K. The Indian Army will do whatever it has in mind to do, in its own time, to exact a heavy enough cost on its Pakistani counterpart for the latter to rethink its policy of excess.
