Heck, the new Iraqi government ought to just demand that all creditors provide them with a complete billing list of all items that were allegedly sold to Baghdad, showing what each item was, in what quantity, and the companies involved in the purchase and sale.
Considering that most were probably illegal under the sanction policy, those debts could most probably be ignored by the new regime.
I'm saving this one for the next time some Bush-hater tries to bring this up to change the subject from the fact that they lost.
