"The former high-level Bush Administration official was just as blunt. 'If a Pakistani general is talking to you about nuclear issues, and his lips are moving, he’s lying,' he said. 'The Pakistanis wouldn’t share their secrets with anybody, and certainly not with a country that, from their point of view, used them like a Dixie cup and then threw them away.' "
