I have read enough about it & it all comes down to Musharraf losing his way with the lawyers agitation.
Indeed, but before the movement when Musharraf as the at peak of his power the peace deal could have been signed with the full backing of the Establishment. India was the one which hesitated, not Pakistan. Another example of how Pakistan wants to achieve peace but India with its mindset of 'perpetual hatred' is not ready to come to peace terms with Pakistan.
The very fact that the PPP government backtracked proved right what many in India doubted, whether Pakistan would simply resile from its position once Musharraf was no more in the seat.
Not really, if India would have signed the deal it would have been with the State of Pakistan, thus PPP Government would have no choice but to accept it. A similar comparison could be made with the Economic Corridor with China, no matter which political party is in the Federal Government, they have to honour that agreement.
The only reason why the PPP Government backed out is because they did not want to give Musharraf any credit and were hell bent on destroying any legacy Musharraf left. I guess those many doubters in India predicted wrong and continued on with their policy of 'perpetual hatred'.
The deal was to be between India & Pakistan, no point if someone repudiated Musharraf's agreement as being of no consequence.
If it would have been signed than yes, it was between the States and not any political entity.
Evidence for any increase or even funding is not available except in the very fertile imaginations of some.
I don't think you know how the world of espionage works, there is never any hard evidence left unless there is a major fu** up. This is why India is yet to furnish any credible evidence linking any terrorist attacks within India with the State of Pakistan. There is a reason why the US Government has set a bounty of $10 million to solicit evidence against HS, they themselves don't have a smoking gun. Your hired guns are singing like birds and revealing everything during interrogation, those consulates are not there to give visas to poor Afghans.
As for Sabre rattling, that is not much of an issue. Your politicians & army chiefs have been doing it for years on Kashmir.
There was not any sabre rattling from the Pakistani side, it began from India and than answered by Pakistan. I can tell you one thing that there was genuine interest from the Pakistani side whether the Army or the Political Leadership to achieve peace with India. This is why NS went to India for Modi's inauguration and a follow up visit, but with the way he was treated in India has left a really sour taste especially on NS mouth who could have been considered at the time a genuine Indian Lover.
