A panel sponsored by the Council on Foreign Relations wants the United States to focus not on the defense of our own borders, but rather create what effectively would be a common border that includes Mexico and Canada. CHRISTINE ROMANS, CNN CORRESPONDENT: On Capitol Hill, testimony [is] calling for Americans to start thinking like citizens of North America and treat the U.S., Mexico and Canada like one big country. That's the view in a report called Building a North American Community." It envisions a common border around the U.S., Mexico and Canada in just five years, a border pass for residents of the three countries, and a freer flow of goods and people. [Task force member Robert] PASTOR: What we hope to accomplish by 2010 is a common external tariff which will mean that goods can move easily across the border. We want a common security perimeter around all of North America. ROMANS: Security experts say folding Mexico and Canada into the U.S. is a grave breach of that sovereignty. [The report calls for] temporary migrant worker programs expanded with full mobility of labor between the three countries in the next five years. The idea here is to make North America more like the European Union. [CNN Anchor Lou] DOBBS: Americans must think that our political and academic elites have gone utterly mad at a time when three-and-a-half years, approaching four years after September 11, we still don't have border security. And this group of elites is talking about not defending our borders, finally, but rather creating new ones. It's astonishing.
