The programme was, quite simply, the most ambitious experiment in aid ever undertaken by the United Nations.And that's why sanctions never work: they hurt the poor, oppressed population, while the political elite ride high on the hog. The oil-for-food scheme was designed to try to prevent that, but there were dozens of reports in the 1990s (and now, lots of proof) that most of the money was diverted away from the poor, and into Saddam's vaults.
It became a test of the organisation's capacity to shield ordinary people from the potentially catastrophic impact of sanctions aimed at a political elite.

The American-led coalition has renegotiated almost all of the contracts and re-employed most of the local staff.
