Kudos to the UK http://news.bbc.co.uk/2/hi/science/nature/2970503.stm
A spokeswoman for the UK Ministry of Defence (MoD) told BBC News Online: "Legally, we have no obligation to clean up the remains of the DU we used. It's the responsibility of the new regime in Baghdad.
"But morally we do recognise an obligation, as we have in the past. We helped in the removal of DU from Kosovo.
"We'll be helping in any way we can, specifically by providing money for the clean-up, and by making available records of where the ammunition was fired.
