New Delhi has said that a serious and sustained dialogue with Islamabad can thrive only in a climate free of terrorism directed against India from Pakistan. In an interview to a journal, the Foreign Secretary Nirupama Rao said otherwise, the trust deficit and public alienation towards Pakistan would only deepen. Rao said that while some steps had been taken on the Mumbai terror attack case by Pakistan, including arrests of seven persons, and the declaration of 20 more as proclaimed offenders, much more needs to be done. She said that focused and determined investigation of the conspiracy, the bringing of the perpetrators to justice, were all tasks that remain to be completed. She said that the trial which had moved at a glacial pace was a matter of concern. The Foreign Secretary admitted that the path to a lasting peace with Pakistan would not be easy because of the inherently complex and seemingly intractable nature of our differences. Replying to a question on Wikileaks revelations, she said that what they indicate was known to India. She said that Pakistani hostility towards India’s presence in Afghanistan, raises troubling questions about Pakistani complicity. The Wikileaks disclosures have brought this into even sharper focus.
