Will you give us then Dawood Ibrahim, Masood Azhar, Hafiz Saeed and others?. If that is the case India wouldn't mind giving any of them, but I think it has to be two ways. The question will be who will blink first.
I also remember the case of Khalistani Hijacker in 1970s or so. He was tried in Paksitan, convicted by Pakistani courts. And guess what, he served his jail term in a Gurudwar. When India asked him to be extradited, pakistan denied that he is present in Pakistan. I sense some similar things going to happen here.
Well, Pakistan has been blinking for a while. I has released hundred of Indian prisoners, while there was no response from the next door. So i dont think Pakistan is very interested in that blinking game anymore.
