UNlikely

Does anyone actually think Benon Sevan, Joseph Stephanides or anyone else will be held accountable for oil-for-food? Stephanides is being suspended with pay (Sevan is retired), their pensions "can't be touched" regardless, and this is apparently the beginning of a "disciplinary process" that will most likely take ages, kill a few dozen forests and end with no hard feelings. (Remember this?)

One of the purposes the UN ostensibly serves in developing countries, especially failed states, is that it projects an example of functional governance—transparency, merit-based advancement, accountability, etc. For all their failings, I think field-based projects very often do this. To get paid for being good at what you do—or fired for not being so good at it—can be, as far as I've seen, a new and potentially formative concept for someone raised in a system based on nepotism and graft. Which is why it's so destructive when even the weather people can't keep their checks straight, and war criminals end up with backpay.
