Yes, you are right, Russia and other countries are the biggest benefactors when India makes weapons purchases but the same logic cannot be applied to India and Pakistan both.
And ofcourse, there could be some vested interests of major defence companies that would not want violence in India to end.
Also, please note, I just said that China is the main benefactor, I never said China could be behind the incident.
very well put my dear
thats what I am saying (in my earlier post to other Indians) that same logic cant be used for China because its India & Pakistan who both have their military spend against each other (yea yea India does say that it is looking beyond Pakistan now, but 80%+ of its forces deployments still show Pakistan centric view)
I am not sure if other people are smart enough or care enough to distinguish between the words culprit and benefactor. (they can be used interchangeably too) because a culprit is benefactor by default too 
Re destruction of the American surveillance crafts, China doesn’t automatically become a confirmed supplier of the future aircrafts that would replace these planes. Defence purchases of strategic importance take years of formulating needs, selecting planning and negotiations. Incidents like these don’t mean that they are drastically changed as suggested. Attrition and losses are always accounted for and don’t just result in a U turn in the decisions.
The incident asks everyone to think who considered these planes to be a risk? TTP and Al Qaeda live among civilians in tribal areas and the settled cities not in submersibles and submarines. They were not even that symbolic or well known to public like F-16 or JF-17 might be. Secondly, the method and execution was only similar to Siri Lanken team attack where the intent was not to stay and fight till death but complete the objective and leave the place, except this time one team was to stay on and keep the security forces engaged until the “core” group escaped.
The terrorist team may well have been consisting of well trained Pakistani Taliban (read LeT, LeJ, TTP or sipah Sahabah) + Indian commandos (sans explosive jackets).
This is nothing new at all. When Afghan Mujahideen were introduced with Stinger missiles and 120Mm mortars, both ISI and CIA operatives accompanied the assault teams in person in the initial missions to see the live action. Likewise, British special agents were Para dropped in occupied France to meet up with resistance fighters to plan attacks on Nazi officers, fuel and ammo depots.
The prize here was too big, too crucial too strategic to be given over to some local fanatics no matter how much they would have been trained in Afghanistan so the “core” team accompanied by the kamikaze group reached the targets, destroyed them and left the scene (just like the attacker on Siri Lanken team in Lahore) while the kamikaze part of the terrorists continued to engage the security forces, taking advantage of their restrain due to the Naval assets in the area.
We got to be careful with the wording here because it would mean every natural or human disaster means that the companies selling infrastructure and goods to replace and reconstruct are benefactors. And sadly, the recent natural disasters in the subcontinent have been indiscriminate and devastating so using such words would haunt anyone with a bit of conscience and care about the victims. I am not begging for pity here, lol, far from it (actually I find myself impressed by the success)just saying that fate is a strange thing and such banter has a habit of coming back.
I remember that last year there were some Indians posting jokes and fun about a terrorist attack somewhere in Pakistan and then in few days there was a terrorist attack by Naxlis in India on a train. I went quickly to that thread and requested everyone not to use this as a revenge or response to usual Indian posts, as it was a human tragedy.
