Stripped of the rhetoric of his anger against India and his attempt to show to his people that he’s not acting under any threat or pressure, General Pervez Musharraf reiterated his January 12 promise today that Pakistan was ‘‘doing nothing across the Line of Control.’’ And that he would never allow the ‘‘export of terrorism anywhere in the world from within Pakistan.’’ The vigorous emphasis on disallowing terrorism, which did not escape the notice of Indian government officials here, was unusually made three times during his 25-minute address to the nation.
