Once it became clear some months ago that Saddam Hussein had been telling the truth about not having weapons of mass destruction or connections to al-Qaida, it should have been an embarrassment to the neo-conservatives who talked President George Bush into war with Iraq.
France, Germany, Russia and China had become obstacles to regime change in Baghdad, either at the UN Security Council or at Nato, or both.
It has now also been shown that Iraq had met the conditions of the UN Security Council post-Gulf war resolution which demanded he destroy his unconventional weapons before economic sanctions could be lifted and the Iraqi government could resume the sale of oil.
My educated guess is that the neo-cons who continue to have serious influence on the Bush administration through Vice-President Dick Cheney's office, knew full well that if the Volcker commission did its job honestly, it would be able to report that the oil-for-food programme worked pretty much as it was designed to work.
