Off course. Let me start off by saying that when i said "India"; i did not mean the average Akshay, Vinod or Talwinder. I meant the State of India, the establishment, the strategic planners and the real lever pushers.
There is never any wish to interfere or destabilize another nation, but it is still done and it is based on strategic and geopolitical compulsions. India just wants to payback Pakistan for Kashmir during the 90's, Simple. Its a golden opportunity as India was able to piggy back on American efforts without putting much effort much to the disappointment of the Americans, attack Pakistan's vulnerable Western flank. The real challenge starts now, as the Americans are imposing stabilizing steps due to their withdrawal in 2014, sooner or later they would ask the Indians to stop these destabilizing actions. What is India going to do than?
Well off course. Let me put it this way, i am not saying that Indian trainers are actively training and proactively providing services to TTP or BLA. But we do we have evidence suggesting that Indian money and weapons have been provided to TTP and BLA. We have pictures of senior BLA commanders meeting up with Indian diplomats, they have been shared with the US. Almost 2 months ago i had the pleasure of having dinner with a battalion commander who just recently returned from FATA. According to him, they conducted interrogations of senior TTP commanders whom revealed that they received weapons and money from Indian middle men in Afghanistan. You don't possibly believe that those 16 consulates in Afghanistan are present to provide visas to poor Afghans. Its simple, every country has strategic interests and they consider it their duty to fulfill them.
