@Ray; you don't seem to have understood what I meant with the India deal.
I meant to address the one Pakistani interest that totally overrides whatever interest they have in TB and AQ: India's ability to invade Pakistan.

Threaten to push India into such heights of military power that Pakistan would be hopeless and Pakistan would be forced to do just about everything because this touches their core vital interest with a glowing axe.

Bribing Pakistan invited them to play you - threaten them indirectly at their core interest and they'll #### their pants. Even the ISI's vital interest would be hit.

There would not need to be any arms deal. Just the credible threat.
