i can tell you there is a higher chance of what ifti has said and it seems logical if india has to be dominant in the region and for that pakistan has to be contained geographically.
cut balochistan on one side and NWFP on other and what you have remaining is sindh and punjab india on one side and sea on other..
but i am sure we arent that weak even now to let this happen.
India, America or for that matter any foreign country are capable of achieving a big zero if we Pakistanis become sensible and realise that the real threat to us are terrorist/gangsters from within ourselves...
