President Pervez Musharraf of Pakistan said yesterday that he has come to the United States in search of major gestures from the Bush administration, including the release of American F-16 fighters sold to Pakistan when it was an ally against the Soviet Union and then withheld because of the country's development of nuclear weapons. In an interview with The New York Times, General Musharraf, who is in New York for the United Nations General Assembly, said he would be asking President Bush at their meeting on Saturday for concrete "gestures" in response to Pakistan's strong support in the campaign against terrorism.
