On September 12, 2001, Pakistan’s ISI (Inter-Services Intelligence) head General Mahmud Ahmad, who was visiting Washington, “was summoned to the State Department to see Deputy Secretary of State Richard Armitage. According to [Pakistani President Pervez] Musharraf’s account of the meeting, Mahmud was told either Pakistan cooperated with the United States against al Qaeda or the Taliban, or it would be bombed mercilessly back into the Stone Age. Both Mahmud and Armitage deny referring to the Stone Age, although Mahmud later complained bitterly to Ambassador Wendy Chamberlin in Islamabad that Armitage had been very rude in the meeting.”
