Sounding more like a cast member of the Sopranos than an international leader, in testimony by one key witness Mr Wolfowitz declares: "If they fuck with me or Shaha, I have enough on them to fuck them too."

The remarks were published in a report detailing the controversy that erupted last month after the size of Ms Riza's pay rises was revealed. The report slates Mr Wolfowitz for his "questionable judgment and a preoccupation with self-interest", saying: "Mr Wolfowitz saw himself as the outsider to whom the established rules and standards did not apply."

The report brushed off Mr Wolfowitz's defence that he thought he had been asked to arrange Ms Riza's pay package, observing that "the interpretation given by Mr Wolfowitz ... simply turns logic on its head".

The shorthand version of Paul Wolfowitz ... is inadequate in important ways. It completely misses his style, which relies on patient logic and respectful, soft-spoken engagement rather than on fire-breathing conviction.
