Let's not pretend that India hasn't had a hand in helping destabilize its neighborhood. Ask the Sri Lankans, and the Nepalese if you don't give a **** about Pakistan's opinion.
There's a very good reason why SAARC fell apart, it wasn't because India convinced everyone to kick out Pakistan, it was because half of South Asia doesn't trust India, which has very little to do with Pakistan. The other half are either puppets or reluctant partners of India.
This is the reality that India has to contend with if it wants to dominate the region.
As for Pakistan's internal strife, India better pray that IK doesn't win this because if he comes back to power, India is going to back to being shamed on the international stage.
