Pakistan had clearly demanded that India admit that Sarabjit is Indian spy. Meanwhile Sarabjit's confession to Pakis showed he worked based on instructions from Amritsar branch of Indian intellegence and he was involved in Paki bomb blasts. This means that if India took all necessary steps (asusming effective steps) then India admitted to state sponsored terrorism. If this is not the case, then India may be exchanging some Paki spy like Afzal Guru. Both these options are dreadful. So Mr PM please explain what steps you are referring to.
