1. I don't believe in this 'non-state actors' nonsense. This is nothing but a smokescreen to protect people whom PA has regarded as strategic assets against India.
2. For these terrorist elements to harm India and Indian economy on the scale they have harmed Pakistan and Pakistan's economy, they would need to be based in India itself and that is obviously not going to happen. They might have sleeper cells here and there in India but that is nothing in comparison to the set up they have in Pakistan. They might send a batch of 10 kids to kill a few hundred Indians here and there but again, that is not something we cannot deal with minus Pakistan's co-operation. The US (after 9/11) has shown that it is not impossible to prevent major attacks by such elements.
3. We have ample amount of time to focus on ther issues like economy, development, infrastructure, naxals, kashmir etc. and we are paying attention to these issues. None of these issues is in such a dire need of co-operation from Pakistan as to force us to the dialogue table.
