Mumbai Evidence Shows Pakistan Link -- Boucher

If you think that Raw did marriot bombing and killed Benazir then you are in delusion.
First, the problems of Pakistan is not of Indias making. The support to jihadi group in Afghanistan and Kashmir is taken by Pakistan govt and supported by the military. Now when they come back to bite you, it is indeed your job to clean them up. You cannot expect other countries to fight your war against your own citizen.
If there is a will in Pakistans ruling establishment and military I am pretty sure that these militants can be eliminated. But instead Pakistans army and govt are training their guns on India.
From your post Pakistan is on a suicide mission. They will not live but they will also not let others live.
