NEW DELHI (Agencies) - Indian Prime Minister Manmohan Singh said on Friday Indias decision to hold foreign secretary-level talks with Pakistan was calculated. Responding to the debate on motion of thanks to the Presidents address in Lok Sabha, Singh said it was not a sudden decision but a calculated one. Singh said he had earlier offered to resume talks on humanitarian issues. All problems with Pakistan can be resolved bilaterally if it adopted a reasonable attitude in dealing with terrorists which target India, Indian Prime Minister said, adding that dialogue was the only way forward with Pakistan. Singh said he was a strong advocate of dialogue with Pakistan but Islamabad must not allow territory under its control to be used for terrorism against India. For any meaningful dialogue to proceed the terror machine has to be controlled by Pakistan, he told parliament. Singhs statement came a day after Pakistan said it had put forward a roadmap on how to revive talks with Indias political leadership and had urged New Delhi to respond to the proposal. The prime minister did not comment on the Pakistani plan but said: I have never believed channels of communication with Pakistan should break down... the chances of miscalculation can only increase in a situation of no contact. The US and the Soviet Union, even at the height of the Cold War had kept communication channels open, Singh added. He denied charges that he had sought mediation between Pakistan and India by Saudi Arabia and that talks with Pakistan were held under US pressure. Our policy towards Pakistan is consistent, cautious and realistic, he said.
