This logic, even if accepted at face value, is still very odd. We are talking about opinions in 2013. What happened pre 1947, in 1948, in 1965, in 1971, 1984, 1999 has been consigned to history. What matters now is the perception in India that Pakistan still supports terrorist organisations which carry out attacks in India. If that changes, Indian opinion is guaranteed to change. Musharraf & MMS came close to formulating a peace agreement. Had that succeeded, I'm reasonably sure that Indians would have changed their views on Pakistan. It didn't, your PPP government reneged on that agreement (back channel), 26/11 happened & the cycle of violence & hatred endures. Today India is more wary, MMS is a lot weaker & any new government in India will have plenty to do before it bothers itself with a peace push with Pakistan. I believe that for the immediate future, we are unlikely to see much movement on this.
It is important to understand that Pakistan's position vis-a-vis India has progressively deteriorated. In 1999, during Vajpayee's bus yatra, Pakistan was in a much better situation which went downhill after the Kargil war, the coup, 9/11, Parliament attacks (in India) etc. The next time a peace deal was worked on, Pakistan was settling for a lot less. That was in 2004. The change in government in Indian in that year pushed the nascent peace process further back & by 2007 when it was being firmed up, the balance had decisively shifted in India's way. That too didn't work & now in 2013, Pakistan is an even worse position from which to negotiate. The last few years have seen the hardening in Indian position to a point where senior Indian decision makers question the need & the ability(of Pakistan) to make any agreement, arguing that a cold peace is the best we can hope for.
