India's support to terrorism in Pakistan is a bogey, a smokescreen that never yields any proof. For a long time people in Pakistan have been wrapped up around blaming India because lets face it "It has to be India right? Who else wants to see us fail?"
But that has cost us to miss the more obvious signs of what lays smack in front of us. TTP suicide bomber that killed the 6 CIA agents in Khost was sent into the TTP by the CIA and was actually a CIA agent that just happened to cross them. So the history of CIA and TTP agents working together infilitrating each other is there. Their goals are not the same for them to form a marriage, but a one night stand is quite on the cards.
I would advise Pakistanis always not to get too sucked in with the Indian boogeyman being sold to them. Go with tangible evidences.
DynCorp operates in Pakistan. Fact.
Xe Operates in Pakistan. Fact.
Drones operate in Pakistan. Fact.
I'm still trying to find this Indian article where back when we started pointing fingers at India, the article essentially said "Don't look at us, look at what your new best friends are up to".
Indian official admitted before to "pumping money into Balochistan". That is a fact. There's also some stuff in the wikileaks, wrt British Intelligence accusing India of supporting insurgents in Balochistan.
