With the end of the Iraq war, the globalisation war is heating up around trade again, this time over the issue of genetically modified food. George W. Bush is once more attacking "Old Europe," claiming that it is denying food to starving Africans, after several African countries declined US aid in the form of genetically modified food out of concern that it might taint their own crops and block sales to Europe. And once again the United States is opposing a United Nations approach, this time in the form of the Cartagena Protocol on Biosafety, signed by more than 100 nations, which establishes rules to regulate GMOs.
