Well Pakistan gets blamed for many other mishaps that happen in India specially in IOK.Sir, the red corridor is associated with Pakistan very sparingly. Even when the foreign hand is talked about, China is blamed for it. Pakistan funding Naxalism in India is far fetched except for extremely foolish media houses.
On the other hand, every single attack on Pakistani forces by TTP or BLA/BLF is pinned on India by Pakistan. You can see it for yourself on this very forum.
I posted the link to Naxal attack to show that we all have our troubles.
