The U.S. Government should contribute funds to help contain contamination in Iraq caused by weapons that used DU (depleted uranium) ammunition because it is likely that everyday citizens could be affected. If it were just military targets that would be affected, then the U.S. should not be obligated, but Iraqi civilians should not have to be exposed to it.
America has a moral responsibility to at least contribute funding to help contain contamination. Not only that, but the other governments that had a part in it need to help too. Contributing funds is the least we can do. I don't know if it's possible for us to send people over there to do it, but sending money should be the bare minimum.
No, the United States government is so deep in debt that they need to stop worrying about other countries and focus on spending money only where they have to. There is not enough depleted uranium in Iraq to contaminate the people, and no one is going to get harmed from it.
Depleted uranium is not significantly damaging to the environment, and there is no reason to spend tons of money dealing with yet another problem that only sounds dangerous, rather than actually being dangerous. All of the actual radioactive material that could be dangerous is contained, and is very sparse to begin with.
The American government has already spent way too much money in Iraq at this point. It's time for the Iraqi government and the Iraqi people to clean up their own mess causes by depleted uranium ammunition. Those stockpiles are part of Saddam Hussein's alleged cache of weapons of mass destruction that got the George W. Bush administration in a tizzy in 2003.
