“We should have our people reassess-what all this means to the common citizen, the region (North America);…what it represents to our workers to have available work, thanks to the fact that NORTH AMERICA can be a FULLY INTEGRATED REGION.” (Felipe Calderon, President of Mexico, speaking at the “Three Amigos” summit in Montebello, Canada, August 21, 2007), See also 
“Our economic focus should be on the creation of a common economic space that expands economic opportunities for all peoples in the region (North America, CFR plan), a space in which trade, capital, and people flow freely.” 
George Bush’s push for another “comprehensive” immigration bill may be his last chance to put into place the key needed to integrate North America into a union before he leaves office (despite his recent comment that talk of a union is “comical”).
The fact is that he needs legislation by Congress to legally open up our interior borders with Mexico and Canada. This would make it possible for the full integration of North America, including a government.
I’ve written a number of times that the Council on Foreign Relations Task Force Report on Building a North American Community is a blueprint for the Security and Prosperity Partnership of North America as well as the eventual integration of Canada, Mexico, and the United States.
The SPP was agreed to by George Bush and the leaders of Canada and Mexico on March 23, 2005 in Waco, Texas. Many of the goals of the SPP can be found in the CFR plan and are currently being implemented behind closed doors at the U.S. Department of Commerce.
However, there is one program that is essential for the integration of the three nations of North America and it cannot be implemented without legislation. And that is a “Common Security Perimeter” around North America which would allow the common internal borders of the three nations to be opened up to a free flow (but regulated) of all citizens and cleared foreigners throughout North America. The illegal immigration problem would be solved. Not only that, but citizens of all three nations would be able to “live and work” anywhere within the perimeter. 
George Bush, Felipe Calderon of Mexico, and Stephen Harper of Canada are very familiar with the CFR plan for building this North American Community. Each nation is responsible for constructing their part of the common security perimeter. And, according to the CFR plan, the only way to achieve this security perimeter is through “specific policy, STATUTORY, and procedural changes in all three nations.” 
It would be impossible for Bush to explain why there is wording in immigration bills over the past two years that provide for a common security perimeter for North America, the source of which is the CFR plan.
Securing the border with Mexico means just that; putting forces and infrastructure in place along our southern border with that nation. What Bush is trying to do is “…achieve operational control over the entire land and maritime borders of the United States.” Canada and Mexico would be doing the same with their borders, coordinating their efforts with the United States. Once completed and certified, the internal borders could be opened to the freer flow of people and commerce within North America. 
George Bush, Michael Chertoff, and Carlos Gutierrez (Commerce Secretary) have recently stated that Congress should try and produce another comprehensive immigration bill just as Chertoff reluctantly announced a “crackdown” on illegal aliens in the United States. There is an excellent chance that provisions for a common security perimeter will be in any new bill.
For a look at three bills which mandate a common security perimeter for North America, go to thelastgringo.com (URL listed below). The bills are S. 853, S. 2611, Comprehensive Immigration Reform Act of 2006, and S. 1639, the last attempted immigration bill. Despite changes in wording designed to confuse the few who bothered to read it, all three bills authorize this security perimeter.
