I agree with Raman's point that we might be expecting chickens even before the eggs are hatched. Knowing Pakistan's way of treating this relationship for last so many years,it would be stupid on our part to straight away trust them.I would rather suggest that India takes up the problem of Terrorism with Pakistan with an altimatum of Zero Infiltration and no casualties in Kashmir or any border area with Pakistan. There is nothing wrong in these efforts of improving relations but this has to be reciprocated.Our neighbours are yet to prove their reliability. As rightly quoted about Pakistan " They always come back."
