The goods the US wants to see restricted are those with a potential military use. Various antibiotics might be used to treat anthrax exposure, Washington argues, making it less costly for Saddam Hussein's forces to use biological weapons. The issue came to the fore in November, when it was revealed that Iraq had approached Turkey for very large quantities of the nerve agent antidote atropine and auto-injectors, which would not be necessary if the drug was to be used for civilian purposes. Restricting the import of any medicines would be controversial, but the permitted levels could be lowered to ones sufficient for medical but insufficient for military use. The White House also wants to lower the maximum size of trucks Baghdad can purchase, to prevent their use as mobile rocket launchers, and ban certain types of boat that might be used for a similar purpose.
