It is no doubt that Pakistan Army had launched a well planned operation in KERAN. The operation had typical Nawaz Sharif signature for nibbling at the LoC. Therefore, though he makes noise for peace, whenever he becomes PM, he asks his army to straighten the LoC to Pakistan’s advantage.
His offer must have been so tempting that Manmohan Singh, and Vajpayee before him, could not say no. Therefore Singh went ahead and met him in New York despite a lot of hue and cry in the country. I wonder if the US had a hand in it.
