Remember that rather embarrassing mess called Oil For Food (OFF)? The UN mandated black hole where billions and billions of dollars were laundered, err, misappropriated away from precisely the folks who were said to need the aid most?
In case you're drawing a blank, head on over to the GAO's website for their report of the day, appropriately titled: United Nations: Lessons Learned from Oil for Food Program Indicate the Need to Strengthen UN Internal Controls and Oversight Activities, GAO-06-330.
If you've ever questioned the competence of the UN, you'll definitely want to read this report. Nutshell ... the UN is utterly discombobulated and needs a shakeup (or should that be shakedown? Hmm...).
