In May of 2005, the Council on Foreign Relations published their 175-page Report, Building a North American Community. Below is an excerpt from the description of the Report, and a link to the CFR webpage of same.
"When the leaders of Canada, Mexico, and the United States met in Texas recently they underscored the deep ties and shared principles of the three countries. The Council-sponsored Task Force applauds the announced 'Security and Prosperity Partnership of North America', but proposes a more ambitious vision of a new community by 2010 and specific recommendations on how to achieve it."

Those who continue to doubt that plans for the North American Union (NAU) actually exist need to wake up. The United States as we know it soon will be gone.
