Pakistan doenst want to give us any leverage whatsoever. So they will not allow that to happen. India granted Pakistan an MFN quite a few years ago, but Pakistan did not reciprocate.
Remember any involvement of India there makes it feel threatened though there is no need for it. But mutual suspicion will remain and there is no ice breaker here as there is no stable government there with a single minded aim or policy towards resolving any issue with India.
Circumstances dictate changes.
Pakistan then was doing well economically, it was given billions of dollars as reimbursements for WoT, today its economy is in doldrums, its surviving on aid and "charity".
Pakistan doesn't have a large domestic market like India nor can it become an export oriented economy like China and the world is still to come out of the recession.
Pakistan has several choices, let the impasse continue and depend on God's will or take aggressive measures.
If they do nothing at most they can barely survive on bits and pieces or collapse.
If they take aggressive measures they can either hasten the collapse or come out of the mess.
One of the means by which they can come out of the mess is by fostering greater economic relations with India. There are numerous reasons how this will help Pakistan.
Indian aim wrt Pakistan is ensuring that Pakistan ceases to be a security threat and it wouldn't hurt if we are to benefit from Pakistan economically.
At present India is a mere spectator in the whole fiasco and will be for the foreseeable future. In the meanwhile Pakistan will find it hard to solve the economic mess and at the same time maintain military parity with India while India continues to expand its economy and military.
At an opportune time in the future we can present two options on the table to Pak:
1. work with us - greater co-operation, acknowledge our economic might
2. work against us - our patience has run out, we are going to war.
This will present Pak clearly two options when that will ensure their destruction and significant damage to us and second will ensure their survival and our economic benefit.
