Not only does the US get Iraq out of being sucked dry by French/Russian contract debt claims, we get UN approval of the admin.
With extension of Food for Oil, France/Russia gets hope that more contracts will be thrown their way by their compadre Kofi Annan. Will they get them is yet to be seen.
Frankly I think trading a little for UN "approval" was needed. The "interim Iraqi adminstration" program fell apart...and the Iraqis aren't complaining at all. I was surprised. I think maybe they're of the mindset that the US should take control for a while, then leave. Perhaps it's an authoritarian mindset, perhaps a belief that anyone competent to run the country is too infected with Baathism and its crimes.
