Former Mexican president wants North American Union based on EU

Mexico's former president, Vicente Fox, made an astounding admission last night on CNN's Larry King Live when he acknowledged the plan for a NAFTA single currency, a "euro-dollar" as King labeled it.

Fox also vowed to help unite the Americas beyond a trade agreement, following what he described as "a new vision, like we are trying to do with NAFTA".

The comments follow Fox's appearance on The Daily Show in which he advocated the creation of a North American Union based on the model of the European Union.
